QUESTION 19
There are four ways to divide VLAN:
1. Interface-based VLAN;
2. MAC-based VLAN;
3. Protocol-based VLAN;
4. Subnet-based VLAN.
Then the order of these four division methods is:

2 – 4 – 3 – 1 (mac, subnet, protocol, and end priority)

QUESTION 20
Which of the following statements about configuring a virtual switch is incorrect?

The uplink port of the virtual switch allows all VLANs to pass

The virtual machine uses the vNet0 port of the virtual switch, and the port is configured with VLAN100. Then the physical switch port connected to the virtual switch must allow VLAN100 to pass through, otherwise the virtual machine network will be unavailable.

When adding a virtual switch, you must bind a physical interface, and when binding multiple physical interfaces, you must configure link aggregation mode and load sharing mode.

The storage virtual switch must be configured with a P address, otherwise the CVK host cannot mount the iP SAN storage through the storage virtual switch.

QUESTION 21
The following statements about CAS characteristics are correct:

HA comprehensively considers load factors such as virtual machine CPU, memory, I/O throughput, and the affinity of the virtual machine to the physical host, dynamically adjusts the business-responsible division, and improves system availability.

When a server fails, DRS can automatically select an idle server and restart the VM on the idle server.

DRX comprehensively considers load factors such as the virtual machine’s CPU, memory, I/O throughput, and the virtual machine’s affinity to the physical host, dynamically adjusts the business-responsible division, and improves system availability.

V2V supports converting virtual machines in various formats such as vmware, citrix, kvm, etc. into H3CCAS virtual machines

QUESTION 22
Servers are classified into the following categories according to their processor architecture:

RISC architecture server

Blade Server

X86 server

I A-64 Server

QUESTION 23
Which of the following statements about CAS software version upgrade is correct?

As long as you perform the upgrade operation on the CVM host, you can also complete the upgrade operation of the CVK host managed by the CVM host.

Before upgrading the CAS software version, you need to back up your business data.

When upgrading services, it is recommended to shut down the VM normally from within the VM and suspend the shared storage pool.

If you do not clear the browser cache after the upgrade, CAS page access exceptions may occur

QUESTION 24
Three ways to backup a virtual machine. After multiple backups, which of the following statements is correct?

Full backup backs up the most data

Incremental backup is the fastest

Differential backup does not support CBT

Differential backup The first backup is a full backup

QUESTION 25
Which of the following statements about virtual machine templates is correct?

A virtual machine template is a copy of a virtual machine that is used to easily create and configure multiple new virtual machines.

The number of CPUs, memory size, and capacity in the virtual machine template cannot be modified

There are two ways to create a virtual machine template: converting to a template and cloning. Cloning to a template must be done when the virtual machine is shut down.

Make sure the CD-ROM drive is disconnected before creating the template

QUESTION 26
To configure memory for a virtual machine, the following statement is correct

The memory allocated to a virtual machine can be greater than the physical memory

The virtual machine does not occupy memory when it is turned off

The memory configuration of all virtual machines on a host may be greater than the total memory of the host.

The virtual machine memory is modified online, and a cold restart of the virtual machine is required to take effect

QUESTION 27
Which of the following statements about virtual machine cloning is incorrect?

Virtual machine cloning methods include normal cloning, fast cloning and full cloning.

Cloning is only allowed within the same CVK host

The cloned virtual machine has the same operating system, application system and data as the original virtual machine, and the MAC address of the virtual network card is also the same.

The default IP address acquisition method for the cloned virtual machine is DHCP, so there will be no address conflict problem

QUESTION 28
Which of the following statements about the default gateway is incorrect?

After installing the CAS software, the management network gateway is used as the default gateway by default

The server where the CAS system is installed can be configured with multiple default gateways

If the storage network does not run Layer 3, there is no need to configure static routing locally

If the storage network runs at Layer 3, you need to configure static routing locally

QUESTION 29
A company has two departments, R&D and marketing, and has assigned organizations accordingly. Which of the following statements is correct?

Each organization can be allocated multiple cluster computing resources

Organization administrators can only approve virtual machine electronic flows within one organization.

A cluster can only be assigned to a certain organization.

Virtual machines requested by users in the R&D organization only occupy the computing and storage resources of the R&D organization.

QUESTION 30
The following description of virtual machine startup is incorrect

If the CVK host does not have hardware-assisted virtualization enabled, the virtual machine will not be able to start normally.

When the CPU of the CVK host reaches 87%, the virtual machine can still be started with less virtual CPU allocated

After a virtual machine fails to start, the startup failure information will be recorded in the “/var/log/libvirtd.log” log

When a suspended virtual machine is restarted after hibernation, the virtual machine remains in the suspended state.

QUESTION 31
The unit for allocating computing resources is

Host pool

Cluster

Host

Virtual Machine

QUESTION 32
When the virtual machine is started, it prompts that the disk does not exist, but it exists in the CAS front-end interface and the disk capacity is also displayed. What may be the reason?

The backing-file of the virtual machine disk has been deleted

The virtual machine disk’s backing-file has been moved to another directory

There is a problem with the front-end interface display

Disk capacity is too small

QUESTION 33

The cloned virtual machine disk is a three-level architecture

The Base0 file of the cloned virtual machine disk is not the same as the Base0 file of the original virtual machine disk.

The cloned virtual machine disk data may be different from the original virtual machine data

This operation has no impact on the original virtual machine architecture

QUESTION 35
Which of the following statements about sharing files is correct?

Shared file system types include iSCSI shared file system and FC shared file system

A shared file system cannot be mounted simultaneously by hosts in different host pools

FC shared file system does not support FC multipathing

Multiple clusters under a host pool are not allowed to use the same shared file system

QUESTION 36
Which of the following statements about cluster HA is incorrect?

Shared storage is required to implement HA

Hosts that implement HA in the cluster need to mount the same shared storage

After HA is enabled, when a host in the cluster fails, the system can select an idle server and restart the VM on the failed host on the idle server

The cluster enables HA, which can ensure business continuity even when both the server and the shared file system fail.

QUESTION 37
