QUESTION 102
Refer to the exhibits.
A company has added a new user group. Users in the group try to connect to the WLAN and receive errors that the connection has no Internet access. The users cannot reach any resources. The first exhibit shows the record for one of the users who cannot connect. The second exhibit shows the role to which the AOS device assigned the user’s client.
What is a likely problem?

The AOS device does not have the correct RADIUS dictionaries installed on it to understand the Aruba-User-Role VSA.

The AOS device has a server derivation rule configured on it that has overridden the role sent by CPPM.

The clients rejected the server authentication on their side because they do not have the root CA for CPPM’s RADIUS/EAP certificate.

The role name that CPPM is sending does not match the role name configured on the AOS device.

The scenario involves an AOS-8 Mobility Controller (MC) with a WLAN where a new user group has been added. Users in this group cannot connect to the WLAN, receiving errors indicating no Internet access and inability to reach resources. Exhibit 1 shows the ClearPass Policy Manager (CPPM) Access Tracker record for one user:
CPPM sends an Access-Accept with the VSA Radius:Aruba:Aruba-User-Role user_group4.
The endpoint is classified as “Known,” but the user cannot access resources. Exhibit 2 (not provided but described) shows that the AOS device (MC) assigned the user’s client to the “denyall” role, which likely denies all access, explaining the lack of Internet and resource access.
Analysis:
CPPM sends the Aruba-User-Role VSA with the value “user_group4,” indicating that the user should be assigned to the “user_group4” role on the MC.
However, the MC assigns the client to the “denyall” role, which typically denies all traffic, resulting in no Internet or resource access.
The issue lies in why the MC did not apply the “user_group4” role sent by CPPM.
Option A, “The AOS device does not have the correct RADIUS dictionaries installed on it to understand the Aruba-User-Role VSA,” is incorrect. If the MC did not have the correct RADIUS dictionaries to understand the Aruba-User-Role VSA, it would not process the VSA at all, and the issue would likely affect all users, not just the new user group. Additionally, Aruba-User-Role is a standard VSA in AOS-8, and the dictionaries are built into the system.
Option B, “The AOS device has a server derivation rule configured on it that has overridden the role sent by CPPM,” is incorrect. Server derivation rules on the MC can override roles sent by the RADIUS server (e.g., based on attributes like username or NAS-IP), but there is no indication in the scenario that such a rule is configured. If a derivation rule were overriding the role, it would likely affect more users, and the issue would not be specific to the new user group.
Option C, “The clients rejected the server authentication on their side because they do not have the root CA for CPPM’s RADIUS/EAP certificate,” is incorrect. If the clients rejected the server authentication (e.g., due to a missing root CA for CPPM’s certificate), the authentication would fail entirely, and CPPM would not send an Access-Accept with the Aruba-User-Role VSA. The scenario confirms that authentication succeeded (Access-Accept was sent), so this is not the issue.
Option D, “The role name that CPPM is sending does not match the role name configured on the AOS device,” is correct. CPPM sends the role “user_group4” in the Aruba-User-Role VSA, but the MC assigns the client to the “denyall” role. This suggests that the role “user_group4” does not exist on the MC, or there is a mismatch in the role name (e.g., due to case sensitivity, typos, or underscores vs. hyphens). In AOS-8, if the role specified in the Aruba-User-Role VSA does not exist on the MC, the MC falls back to a default role, which in this case appears to be “denyall,” denying all access. The likely problem is that the role name “user_group4” sent by CPPM does not match the role name configured on the MC (e.g., it might be “user-group4” or a different name).
The HPE Aruba Networking AOS-8 8.11 User Guide states:
“When the Mobility Controller receives an Aruba-User-Role VSA in a RADIUS Access-Accept message, it attempts to assign the specified role to the client. If the role name sent by the RADIUS server (e.g., ‘user_group4’) does not match a role configured on the controller, the controller will fall back to a default role, such as ‘denyall,’ which may deny all access. To resolve this, ensure that the role name sent by the RADIUS server matches the role name configured on the controller, accounting for case sensitivity and naming conventions (e.g., underscores vs. hyphens).” (Page 306, Role Assignment Troubleshooting Section) Additionally, the HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide notes:
“A common issue when assigning roles via the Aruba-User-Role VSA is a mismatch between the role name sent by ClearPass and the role name configured on the Aruba device. If the role name does not match (e.g., ‘user_group4’ vs. ‘user-group4’), the device will not apply the intended role, and the client may be assigned a default role like ‘denyall,’ resulting in access issues. Verify that the role names match exactly in both ClearPass and the device configuration.” (Page 290, RADIUS Role Assignment Issues Section)

QUESTION 103
How can hackers implement a man-in-the-middle (MITM) attack against a wireless client?

The hacker uses a combination of software and hardware to jam the RF band and prevent the client from connecting to any wireless networks.

The hacker runs an NMap scan on the wireless client to find its MAC and IP address. The hacker then connects to another network and spoofs those addresses.

The hacker connects a device to the same wireless network as the client and responds to the client’s ARP requests with the hacker device’s MAC address.

The hacker uses spear-phishing to probe for the IP addresses that the client is attempting to reach. The hacker device then spoofs those IP addresses.

QUESTION 104
What is a correct description of a stage in the Lockheed Martin kill chain?

In the delivery stage, the hacker delivers malware to targeted users, often with spear phishing methods.

In the installation phase, hackers seek to install vulnerabilities in operating systems across the network.

In the weaponization stage, malware installed in the targeted network seeks to attack intrusion prevention systems (IPS).

In the exploitation phase, hackers conduct social engineering attacks to exploit weak algorithms and crack user accounts.

The Lockheed Martin Cyber Kill Chain is a framework that describes the stages of a cyber attack, from initial reconnaissance to achieving the attacker’s objective. It is often referenced in HPE Aruba Networking security documentation to help organizations understand and mitigate threats.
Option A, “In the delivery stage, the hacker delivers malware to targeted users, often with spear phishing methods,” is correct. The delivery stage in the Lockheed Martin kill chain involves the attacker transmitting the weaponized payload (e.g., malware) to the target. Spear phishing, where the attacker sends a targeted email with a malicious attachment or link, is a common delivery method. This stage follows reconnaissance (gathering information) and weaponization (creating the malware).
Option B, “In the installation phase, hackers seek to install vulnerabilities in operating systems across the network,” is incorrect. The installation phase involves the attacker installing the malware on the target system to establish persistence (e.g., by creating a backdoor). It does not involve “installing vulnerabilities”; vulnerabilities are pre-existing weaknesses that the attacker exploits in the exploitation phase.
Option C, “In the weaponization stage, malware installed in the targeted network seeks to attack intrusion prevention systems (IPS),” is incorrect. The weaponization stage occurs before delivery and involves the attacker creating a deliverable payload (e.g., combining malware with an exploit). The malware is not yet installed in the target network during this stage, and attacking an IPS is not the purpose of weaponization.
Option D, “In the exploitation phase, hackers conduct social engineering attacks to exploit weak algorithms and crack user accounts,” is incorrect. The exploitation phase involves the attacker exploiting a vulnerability (e.g., a software flaw) to execute the malware on the target system. Social engineering (e.g., phishing) is typically part of the delivery stage, not exploitation, and “exploiting weak algorithms” is not a standard description of this phase.
The HPE Aruba Networking Security Guide states:
“The Lockheed Martin Cyber Kill Chain describes the stages of a cyber attack. In the delivery stage, the attacker delivers the weaponized payload to the target, often using methods like spear phishing emails with malicious attachments or links. This stage follows reconnaissance (gathering information about the target) and weaponization (creating the malware payload).” (Page 18, Cyber Kill Chain Overview Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
“Understanding the Lockheed Martin kill chain helps in threat mitigation. The delivery stage involves the attacker sending malware to the target, commonly through spear phishing, where a targeted email tricks the user into downloading the malware or clicking a malicious link.” (Page 420, Threat Mitigation Section)

A user visits a website and downloads a file that contains a worm, which sell-replicates throughout the network.

An attack exploits an operating system vulnerability and locks out users until they pay the ransom.

QUESTION 111
Which is a correct description of a Public Key Infrastructure (PKI)?

A device uses Intermediate Certification Authorities (CAs) to enable it to trust root CAs that are different from the root CA that signed its own certificate.

A user must manually choose to trust intermediate and end-entity certificates, or those certificates must be installed on the device as trusted in advance.

Root Certification Authorities (CAs) primarily sign certificates, and Intermediate Certification Authorities (CAs) primarily validate signatures.

A user must manually choose to trust a root Certification Authority (CA) certificate, or the root CA certificate must be installed on the device as trusted.

QUESTION 112

What is one thing can you determine from the exhibits?

CPPM originally assigned the client to a role for non-profiled devices. It sent a CoA to the authenticator after it categorized the device.

CPPM sent a CoA message to the client to prompt the client to submit information that CPPM can use to profile it.

CPPM was never able to determine a device category for this device, so you need to check settings in the network infrastructure to ensure they support CPPM’s endpoint classification.

CPPM first assigned the client to a role based on the user’s identity. Then, it discovered that the client had an invalid category, so it sent a CoA to blacklist the client.

QUESTION 115
You have been asked to rind logs related to port authentication on an ArubaOS-CX switch for events logged in the past several hours But. you are having trouble searching through the logs What is one approach that you can take to find the relevant logs?

Add the “-C and *-c port-access” options to the “show logging” command.

Configure a logging Tiller for the “port-access” category, and apply that filter globally.

Enable debugging for “portaccess” to move the relevant logs to a buffer.

Specify a logging facility that selects for “port-access” messages.

QUESTION 116
You have been asked to send RADIUS debug messages from an AOS-CX switch to a central SIEM server at 10.5.15.6. The server is already defined on the switch with this command:
logging 10.5.15.6
You enter this command:
debug radius all
What is the correct debug destination?

file

console

buffer

syslog

The scenario involves an AOS-CX switch that needs to send RADIUS debug messages to a central SIEM server at 10.5.15.6. The switch has already been configured to send logs to the SIEM server with the command logging 10.5.15.6, and the command debug radius all has been entered to enable RADIUS debugging.
Debug Command: The debug radius all command enables debugging for all RADIUS-related events on the AOS-CX switch, generating detailed debug messages for RADIUS authentication, accounting, and other operations.
Debug Destination: Debug messages on AOS-CX switches can be sent to various destinations, such as the console, a file, the debug buffer, or a Syslog server. The logging 10.5.15.6 command indicates that the switch is configured to send logs to a Syslog server at 10.5.15.6 (using UDP port 514 by default, unless specified otherwise).
Option D, “syslog,” is correct. To send RADIUS debug messages to the SIEM server, the debug destination must be set to “syslog,” as the SIEM server is already defined as a Syslog destination with logging 10.5.15.6. The command to set the debug destination to Syslog is debug destination syslog, which ensures that the RADIUS debug messages are sent to the configured Syslog server (10.5.15.6).
Option A, “file,” is incorrect. Sending debug messages to a file (e.g., using debug destination file) stores the messages on the switch’s filesystem, not on the SIEM server.
Option B, “console,” is incorrect. Sending debug messages to the console (e.g., using debug destination console) displays them on the switch’s console session, not on the SIEM server.
Option C, “buffer,” is incorrect. Sending debug messages to the buffer (e.g., using debug destination buffer) stores them in the switch’s debug buffer, which can be viewed with show debug buffer, but does not send them to the SIEM server.
The HPE Aruba Networking AOS-CX 10.12 System Management Guide states:
“To send debug messages, such as RADIUS debug messages, to a central SIEM server, first configure the Syslog server with the logging <ip-address> command (e.g., logging 10.5.15.6). Then, enable the desired debug with a command like debug radius all, and set the debug destination to Syslog using debug destination syslog. This ensures that all debug messages are sent to the configured Syslog server for centralized logging.” (Page 92, Debug Logging Section) Additionally, the HPE Aruba Networking AOS-CX 10.12 Security Guide notes:
“RADIUS debug messages can be sent to a Syslog server for centralized monitoring. After enabling RADIUS debugging with debug radius all, use debug destination syslog to send the messages to the Syslog server configured with the logging command, such as a SIEM server at 10.5.15.6.” (Page 152, RADIUS Debugging Section)

QUESTION 117
A company is deploying ArubaOS-CX switches to support 135 employees, which will tunnel client traffic to an Aruba Mobility Controller (MC) for the MC to apply firewall policies and deep packet inspection (DPI).
This MC will be dedicated to receiving traffic from the ArubaOS-CX switches.
What are the licensing requirements for the MC?

one AP license per-switch

one PEF license per-switch

one PEF license per-switch. and one WCC license per-switch

one AP license per-switch. and one PEF license per-switch

QUESTION 118
A company has HPE Aruba Networking Mobility Controllers (MCs), campus APs, and AOS-CX switches. The company plans to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to classify endpoints by type. This company is using only CPPM and no other HPE Aruba Networking ClearPass solutions.
The HPE Aruba Networking ClearPass admins tell you that they want to use HTTP User-Agent strings to help profile the endpoints.
What should you do as a part of setting up Mobility Controllers (MCs) to support this requirement?

Create datapath mirrors that use the CPPM’s IP address as the destination.

Create an IF-MAP profile, which specifies credentials for an API admin account on CPPM.

Create control path mirrors to mirror HTTP traffic from clients to CPPM.

Create a firewall whitelist rule that permits HTTP and CPPM’s IP address.

HPE Aruba Networking ClearPass Policy Manager (CPPM) uses device profiling to classify endpoints, and one of its profiling methods involves analyzing HTTP User-Agent strings to identify device types (e.g., iPhone, Windows laptop). HTTP User-Agent strings are sent in HTTP headers when a client accesses a website. For CPPM to profile devices using HTTP User-Agent strings, it must receive the HTTP traffic from the clients. In this scenario, the company is using Mobility Controllers (MCs), campus APs, and AOS-CX switches, and CPPM is the only ClearPass solution in use.
HTTP User-Agent Profiling: CPPM can passively profile devices by analyzing HTTP traffic, but it needs to receive this traffic. In an AOS-8 architecture, the MC can mirror client traffic to CPPM for profiling. Since HTTP traffic is part of the data plane (user traffic), the MC must mirror the data plane traffic (not control plane traffic) to CPPM.
Option A, “Create datapath mirrors that use the CPPM’s IP address as the destination,” is correct. The MC can be configured to mirror client HTTP traffic to CPPM using a datapath mirror (also known as a GRE mirror). This involves setting up a mirror session on the MC that sends a copy of the client’s HTTP traffic to CPPM’s IP address. CPPM then analyzes the HTTP User-Agent strings in this traffic to profile the endpoints. For example, the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http can be used to mirror HTTP traffic to CPPM.
Option B, “Create an IF-MAP profile, which specifies credentials for an API admin account on CPPM,” is incorrect. IF-MAP (Interface for Metadata Access Points) is a protocol used for sharing profiling data between ClearPass and other systems (e.g., Aruba Introspect), but it is not used for sending HTTP traffic to CPPM for profiling. Additionally, IF-MAP is not relevant when only CPPM is in use.
Option C, “Create control path mirrors to mirror HTTP traffic from clients to CPPM,” is incorrect. Control path (control plane) traffic includes management traffic between the MC and APs (e.g., AP registration, heartbeats), not client HTTP traffic. HTTP traffic is part of the data plane, so a datapath mirror is required, not a control path mirror.
Option D, “Create a firewall whitelist rule that permits HTTP and CPPM’s IP address,” is incorrect. A firewall whitelist rule on the MC might be needed to allow traffic to CPPM, but this is not the primary step for enabling HTTP User-Agent profiling. The key requirement is to mirror the HTTP traffic to CPPM, which is done via a datapath mirror, not a firewall rule.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
“To enable ClearPass Policy Manager (CPPM) to profile devices using HTTP User-Agent strings, the Mobility Controller (MC) must mirror client HTTP traffic to CPPM. This is done by creating a datapath mirror session that sends a copy of the client’s HTTP traffic to CPPM’s IP address. For example, use the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http to mirror HTTP traffic to CPPM. CPPM then analyzes the HTTP User-Agent strings to classify endpoints by type (e.g., iPhone, Windows laptop).” (Page 350, Device Profiling with CPPM Section) Additionally, the HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide notes:
“HTTP User-Agent profiling requires ClearPass to receive HTTP traffic from clients. In an Aruba Mobility Controller environment, configure a datapath mirror to send HTTP traffic to ClearPass’s IP address. ClearPass will parse the HTTP User-Agent strings to identify device types and operating systems, enabling accurate profiling.” (Page 249, HTTP User-Agent Profiling Section)

QUESTION 119
You have been instructed to look in an AOS Security Dashboard’s client list. Your goal is to find clients that belong to the company and have connected to devices that might belong to hackers.
Which client fits this description?

MAC address: d8:50:e6:f3:6d:a4; Client Classification: Authorized; AP Classification: Suspected Rogue

MAC address: d8:50:e6:f3:6e:c5; Client Classification: Interfering; AP Classification: Neighbor

MAC address: d8:50:e6:f3:6e:60; Client Classification: Interfering; AP Classification: Interfering

MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Suspected Rogue

The AOS Security Dashboard in an AOS-8 solution (Mobility Controllers or Mobility Master) provides a client list through its Wireless Intrusion Prevention (WIP) system, showing the classification of clients and the APs they are connected to. The goal is to identify clients that belong to the company (Authorized clients) and have connected to devices that might belong to hackers (rogue or suspected rogue APs).
Client Classification:
Authorized: A client that has successfully authenticated to an authorized AP and is part of the company’s network (e.g., an employee device).
Interfering: A client that is not authenticated to the company’s network and is considered external or potentially malicious.
AP Classification:
Authorized: An AP that is part of the company’s network and managed by the MC.
Suspected Rogue: An AP that is not authorized and is suspected of being malicious, often because it exhibits suspicious behavior (e.g., a BSSID close to an authorized AP, indicating potential spoofing).
Neighbor: An AP that is not part of the company’s network but is not connected to the wired network (e.g., a nearby AP from another organization).
Interfering: An AP that is not part of the company’s network and may be causing interference, but is not necessarily malicious.
The requirement is to find a client that is Authorized (belongs to the company) and connected to a Suspected Rogue AP (might belong to hackers).
Option A: MAC address: d8:50:e6:f3:6d:a4; Client Classification: Authorized; AP Classification: Suspected Rogue This client is classified as “Authorized,” meaning it belongs to the company, and it is connected to a “Suspected Rogue” AP, which might belong to hackers. This matches the requirement perfectly.
Option B: MAC address: d8:50:e6:f3:6e:c5; Client Classification: Interfering; AP Classification: Neighbor This client is “Interfering” (not a company client) and connected to a “Neighbor” AP, which is not considered a hacker’s device (it’s just a nearby AP).
Option C: MAC address: d8:50:e6:f3:6e:60; Client Classification: Interfering; AP Classification: Interfering This client is “Interfering” (not a company client) and connected to an “Interfering” AP, which is not necessarily a hacker’s device (it may just be causing interference).
Option D: MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Suspected Rogue This client is “Interfering” (not a company client), although it is connected to a “Suspected Rogue” AP. It does not meet the requirement of being a company client.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
“The Security Dashboard’s client list in ArubaOS shows the classification of each client and the AP it is connected to. An ‘Authorized’ client is one that has successfully authenticated to an authorized AP and is part of the company’s network. A ‘Suspected Rogue’ AP is an unauthorized AP that exhibits suspicious behavior, such as a BSSID close to an authorized AP, indicating potential spoofing by a hacker. To identify security risks, look for authorized clients connected to suspected rogue APs, as this may indicate a company device has connected to a malicious AP.” (Page 415, Security Dashboard Section) Additionally, the HPE Aruba Networking Security Guide notes:
“WIP classifies clients as ‘Authorized’ if they have authenticated to an authorized AP managed by the controller. A ‘Suspected Rogue’ AP is a potential threat, as it may be attempting to mimic a legitimate AP to lure clients. Identifying authorized clients connected to suspected rogue APs is critical for detecting potential attacks, such as man-in-the-middle attempts by hackers.” (Page 78, WIP Classifications Section)

QUESTION 120
What purpose does an initialization vector (IV) serve for encryption?

It enables programs to convert easily-remembered passphrases to keys of a correct length.

It makes encryption algorithms more secure by ensuring that the same plaintext and key can produce different ciphertext.

It helps parties to negotiate the keys and algorithms used to secure data before data transmission.

It enables the conversion of asymmetric keys into keys that are suitable for symmetric encryption.

An initialization vector (IV) is a random or pseudo-random value used in encryption algorithms to enhance security. It is commonly used in symmetric encryption modes like Cipher Block Chaining (CBC) or Counter (CTR) modes with algorithms such as AES, which is used in WPA3 and other Aruba security features.
Option B, “It makes encryption algorithms more secure by ensuring that the same plaintext and key can produce different ciphertext,” is correct. The primary purpose of an IV is to introduce randomness into the encryption process. When the same plaintext is encrypted with the same key multiple times, the IV ensures that the resulting ciphertext is different each time. This prevents attackers from identifying patterns in the ciphertext, which could otherwise be used to deduce the plaintext or key. For example, in AES-CBC mode, the IV is XORed with the first block of plaintext before encryption, and each subsequent block is chained with the previous ciphertext, ensuring unique outputs.
Option A, “It enables programs to convert easily-remembered passphrases to keys of a correct length,” is incorrect. This describes a key derivation function (KDF), such as PBKDF2, which converts a passphrase into a cryptographic key of the correct length. An IV is not involved in key derivation.
Option C, “It helps parties to negotiate the keys and algorithms used to secure data before data transmission,” is incorrect. This describes a key exchange or handshake protocol (e.g., Diffie-Hellman or the 4-way handshake in WPA3), not the role of an IV. The IV is used during the encryption process, not during key negotiation.
Option D, “It enables the conversion of asymmetric keys into keys that are suitable for symmetric encryption,” is incorrect. This describes a process like hybrid encryption (e.g., using RSA to encrypt a symmetric key), which is not the purpose of an IV. An IV is used in symmetric encryption to enhance security, not to convert keys.
The HPE Aruba Networking Wireless Security Guide states:
“An initialization vector (IV) is a random value used in symmetric encryption algorithms like AES to enhance security. The IV ensures that the same plaintext encrypted with the same key produces different ciphertext each time, preventing attackers from identifying patterns in the ciphertext. In WPA3, for example, the IV is used in AES-GCMP encryption to ensure that each packet is encrypted uniquely, even if the same data is sent multiple times.” (Page 28, Encryption Fundamentals Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
“The initialization vector (IV) in encryption algorithms like AES-CBC or AES-GCMP makes encryption more secure by ensuring that identical plaintext encrypted with the same key results in different ciphertext. This randomness prevents pattern analysis attacks, which could otherwise compromise the security of the encryption.” (Page 282, Wireless Encryption Section)

You are troubleshooting an authentication issue for Aruba switches that enforce 802 IX10 a cluster of Aruba ClearPass Policy Manager (CPPMs) You know that CPPM Is receiving and processing the authentication requests because the Aruba switches are showing Access-Rejects in their statistics However, you cannot find the record tor the Access-Rejects in CPPM Access Tracker What is something you can do to look for the records?

Make sure that CPPM cluster settings are configured to show Access-Rejects

Verify that you are logged in to the CPPM Ul with read-write, not read-only, access

Click Edit in Access viewer and make sure that the correct servers are selected.

Go to the CPPM Event Viewer, because this is where RADIUS Access Rejects are stored.

QUESTION 126
The monitoring admin has asked you to set up an AOS-CX switch to meet these criteria:
Send logs to a SIEM Syslog server at 10.4.13.15 at the standard TCP port (514) Send a log for all events at the “warning” level or above; do not send logs with a lower level than “warning” The switch did not have any “logging” configuration on it. You then entered this command:
AOS-CX(config)# logging 10.4.13.15 tcp vrf default
What should you do to finish configuring to the requirements?

Specify the “warning” severity level for the logging server.

Add logging categories at the global level.

Ask for the Syslog password and configure it on the switch.

Configure logging as a debug destination.

The task is to configure an AOS-CX switch to send logs to a SIEM Syslog server at IP address 10.4.13.15 using TCP port 514, with logs for events at the “warning” severity level or above (i.e., warning, error, critical, alert, emergency). The initial command entered is:
AOS-CX(config)# logging 10.4.13.15 tcp vrf default
This command configures the switch to send logs to the Syslog server at 10.4.13.15 using TCP (port 514 is the default for TCP Syslog unless specified otherwise) and the default VRF. However, this command alone does not specify the severity level of the logs to be sent, which is a requirement of the task.
Severity Level Configuration: AOS-CX switches allow you to specify the severity level for logs sent to a Syslog server. The severity levels, in increasing order of severity, are: debug, informational, notice, warning, error, critical, alert, and emergency. The requirement is to send logs at the “warning” level or above, meaning warning, error, critical, alert, and emergency logs should be sent, but debug, informational, and notice logs should not.
Option A, “Specify the ‘warning’ severity level for the logging server,” is correct. To meet the requirement, you need to add the severity level to the logging configuration for the specific Syslog server. The command to do this is:
AOS-CX(config)# logging 10.4.13.15 severity warning
This command ensures that only logs with a severity of warning or higher are sent to the Syslog server at 10.4.13.15. Since the initial command already specified TCP and the default VRF, this additional command completes the configuration.
Option B, “Add logging categories at the global level,” is incorrect. Logging categories (e.g., system, security, network) are used to filter logs based on the type of event, not the severity level. The requirement is about severity (“warning” or above), not specific categories, so this step is not necessary to meet the stated criteria.
Option C, “Ask for the Syslog password and configure it on the switch,” is incorrect. Syslog servers typically do not require a password for receiving logs, and AOS-CX switches do not have a configuration option to specify a Syslog password. Authentication or encryption for Syslog (e.g., using TLS) is not mentioned in the requirements.
Option D, “Configure logging as a debug destination,” is incorrect. Configuring a debug destination (e.g., using the debug command) is used to send debug-level logs to a destination (e.g., console, buffer, or Syslog), but the requirement is to send logs at the “warning” level or above, not debug-level logs. Additionally, the logging command already specifies the Syslog server as the destination.
The HPE Aruba Networking AOS-CX 10.12 System Management Guide states:
“To configure a Syslog server on an AOS-CX switch, use the logging <ip-address> [tcp | udp] [vrf <vrf-name>] command to specify the server’s IP address, protocol, and VRF. To filter logs by severity, add the severity <level> option to the logging command. For example, logging 10.4.13.15 tcp severity warning sends logs with a severity of warning or higher (warning, error, critical, alert, emergency) to the Syslog server at 10.4.13.15 using TCP. The default port for TCP Syslog is 514.” (Page 89, Syslog Configuration Section) Additionally, the guide notes:
“Severity levels for logging on AOS-CX switches are, in increasing order: debug, informational, notice, warning, error, critical, alert, emergency. Specifying a severity level of ‘warning’ ensures that only logs at that level or higher are sent to the configured destination.” (Page 90, Logging Severity Levels Section)
