NEW QUESTION 348

It can be issued without force

Can be issued on ABR

Issuance can only be enforced

Answer can be issued on ASBR

NEW QUESTION 349
VPN instances are also known as VPN routing forwarding tables (PN Routing and Forwarding table), and there are multiple route forwarding tables on the PE, including a public route forwarding table, one or more VPN route forwarding tables, and VPNv4 Route forwarding table.

False

TRUE

NEW QUESTION 350
The following about BGP routing, what is the wrong description?

Non-aggregate routes take precedence over aggregate routes.

In the case of PrefVal, Local_Preference equality, if the BGP preference of the locally generated route, IBGP route, EBGP route is equal, the valid reference of this generation is preceded by priority.

See the following entry in the BGP routing table: * *17 16 1. 11/32 0 00010 0? Indicates that the route is available non-optimal.

For next_hop unreachable routes are invalid cat by and do not participate in the preference. Flogging case

NEW QUESTION 351
Regarding the domain-authentication-mode md5 hello command in the ISIS process, the correct explanation is
?

ISIS authentication cannot be applied in IPv6 environments.

This command is mainly used to make is the ISIS Hello message carry authentication information during the transmission process.

All router domain authentication methods of the same routing domain are MD5, the password is hello, and lS-IS SNP and LSP will spread normally.

outing domain authentication is primarily used to allow level-1 and Level-2 SNP and LSP messages to carry authentication information during delivery.

NEW QUESTION 352
Which is the correct description of optimal routing election for each protocol in the following options?( Radio).

Route entries in BGP that are unreachable for the next hop are also placed in the IP routing table.
In the

BGP protocol, the best route to reach the same destination circumference is selected by comparing the cost values of the route entries.

The OSPF protocol puts all the routing information in the LSDB into the IP routing table.

From BGP and OSPF, different route entries to reach the same destination segment are learned, and the optimal route is selected to join the IP route table by comparing the protocol’s preference value .

NEW QUESTION 353
Which of the following VPN technologies may have two IP message headers in one message?

GOES

SSL VPN

IPsec VPN

L2TP

NEW QUESTION 354
OSPFV is the GP running on the P4 network) OSPF3 is the KGP running on the IP6 network. OsPFV works the same basic way as OSPF2, such as elections for DR and BDR. As shown in the figure, an engineer uses three routers for IP6 service testing, and he wants to interconnect the IPv6 network by running OSPFv3 Which of the following statements is correct regarding the election of the network DR?

After the network converges, R1 is DR

After the network converges, the engineer modifies the priority of R1 to 100, the priority of R2 to 10, and R3 to the default value. When the network converges again, Rl is DR and R2 is BDR

After the network converges, the broadcast link adds a device, R4, with a priority of 150 When the network converges again, R4 is DR

After the network converges, R1 is powered off and restarted, and when the network converges again, R3 is DR

NEW QUESTION 355
The following description of IGMPv1 and IGMPv2 is correct?( Multiple select).

IGMPv2 message types include member departure packets

IGMPv2 does not support specific group queries

IGMPv1 supports universal group queries

The IGMPv1 message type does not contain members leaving the packet AD

NEW QUESTION 356
The following statement about the VPNv4 address is wrongly described as ?

By default, PE does not perform VPN-target filtering on received VPNv4 routes.

Local PE sets up An Export Target for these routes before releasing VPNv4 routes learned from sites that are directly connected to them to other PEEs attributes, and are published with routes as extended community attributes for BGP.

Carries the RD attribute when BGP publishes both reachable and unreachable VPNv4 routes.

The VPNv4 address has a total of 12 bytes, including an 8-byte route identifier RD (Route Distingulisher) and a 4-byte IPv4 Address prefix.

NEW QUESTION 357
You need to configure smart policy routing on the router to specify that specific traffic is forwarded through an interface. When policy-based routing is applied, what are the two most typical types of information that can be used to forward traffic along a particular path?

The TTL and source IP address of the packet

Source A address and the Layer 2 source address

Source IP address and specific protocol (such as FTP, HTTP, etc.)

Service type header and message length

NEW QUESTION 358
A router Router LSA is shown in the figure, and the error in the following statement is ?

This router supports external routing ingestion

This router is a DR

The Router ID of this router is 100121

This router has established an adjacency relationship

NEW QUESTION 359
BGP4+ is running between two routers, and the neighbor relationship is normal, but the BGP routing table of the router on this side does not have a neighbor route entry.

The route entry in the peer BGP route table is non-optimal.

The next hop address of the

BGP route entry is unreachable

Peer ignore is configured on the peer

The peer is configured with active-route-advertise

NEW QUESTION 360
In the use of the CP protocol, the following description is correct?

The Eth-Trunk interface can be avoided by frequent oscillation interfaceeth-trunkllacppreemptenablelacppreemptdelaydelay-time by following command

Source A address can be configured for load sharing in an enabled link aggregation group with the following command: interface eth-trunk 110ad-balance src-dst-ip

A member interface can be removed from an enabled link aggregation group with the following command: interface GigabitEthernet0/0/1 shutdown interface GigabitEthernet0/0/1 undo eth-trunk 1 interfaceGigabitEthernet0/0/1undoshutdown

The member interface can be joined in the link aggregation group by enabling the following command: interface GigabitEthernet0/0/1 shutdown interface GigabitEthernet0/0/1 trunkport

NEW QUESTION 361
The correct description of the extended features of ISIS is ?

When the amount of information in the Link State Protocol data packet PDU to be released by ISIS is too large, the ISIS router will generate multiple LSP shards to carry more ISIS information.

ISIS can choose whether to authenticate incoming SNP and LSP packets

If there are other vendors’ devices on the network and do not support the LSP sharding function, the sharding expansion mode must be configured as Model-1, otherwise the message will not be recognized by other vendors’ devices.

After you enable the LSP shard extension feature of your router, you can use it without restarting the ISIS process.

NEW QUESTION 362
Which of the following scenarios send free ARP messages?( Multiple choice questions).

After the VRRP protocol master and standby role election is completed

The DHCP client receives an acknowledgment message from the server after it sends it

When a new host configured with an IP address is connected to the network

When a host connected to the switch issues a Ping message.

NEW QUESTION 363
By default, routers running IS-IS in broadcast networks have a period of seconds for DIS to send CSNP packets?

NEW QUESTION 364
Two VTEPs in an XLAN can identify a VXLAN tunnel, and this VXLAN tunnel between the VTEPs will be covered by two NDEs is common to all VNI.

True

False

NEW QUESTION 365
When you deploy LLQ, you need to configure bandwidth parameters, what is the significance of bandwidth parameters?( Single choice questions).

Provides a built-in policer to limit the maximum available bandwidth of a low-latency queue during congestion

The parameter should be as small as possible. It means that the bandwidth is always preserved, and even if the LLQ is set, changing the parameters will reduce the available bandwidth of the interface

It represents a reference CIR to calculate the burst size D of the built-in tactician token bucket Changing parameters is an option because LLQ always takes precedence over other queues

NEW QUESTION 366
Which of the following options enables encapsulation and unencapsulation of VXLAN messages?

VBDIF

VLANIF

VTEP

NEW QUESTION 367
The address resolution feature for NDP in the following description is incorrect?

When sending a neighbor request packet, the source address-is set as the link-local address

of the local interface Two types of ICMPv6 messages,

are used in the address resolution process, neighbor request and neighbor advertisement Address resolution implements the ability to resolve from IPv6 addresses to link-layer addresses

When sending a neighbor request packet, the destination address must be the multicast address of the neighbor’s requested node
