At the pre-defined time.

C.

M When an administrator adds another host to vCenter Server

QUESTION 12

A company has recently incurred financial loss, due to a crashed server that resulted in the loss of critical data. Which two vSphere 6.x features should this company implement to protect against losing critical data due to physical server failure? (Choose two.)

 

A.

Virtual Volumes

B.

Enhanced vMotion Capability

C.

High Availability

D.

Fault Tolerance

 

Correct Answer: CD

Explanation:

VMware HA. The solution in this paper extends the high availability offered by VMware HA by using a feature called VMware Fault Tolerance, which protects mission-critical virtual machines (VMs) from downtime and data loss.

QUESTION 13

In what two situations would an administrator use Storage vMotion? (Choose two.)

 

A.

To create new virtual machines in the host.

B.

To bring powered-down hosts back online.

C.

To select separate locations for the virtual machine disk files.

D.

To migrate virtual machines from one datastore to ano
ther.

 

Correct Answer: CD

Explanation:

You can use vMotion to migrate virtual machines to a different host and datastore simultaneously. In addition, unlike Storage vMotion, which requires a single host to have access to both the source and destination datastore, you can migrate virtual machines across storage accessibility boundaries.

QUESTION 14

How does fault tolerance provide continuous availability?

 

A.

By providing the availability required by most applications running in virtual machines, independent of the operating system and application running in it.

B.

By using a feature called Changed Block Tracking (CBT), which backs up content.

C.

By creating and maintaining a secondary virtual machine that is identical to primary machine.

D.

By using the host as the medium to provide asynchronous replication of datastores.

 

Correct Answer: C

Explanation:

VMware Fault Tolerance provides continuous availability for virtual machines by creating and maintaining a Secondary VM that is identical to, and continuously available to replace, the Primary VM in the event of a failover situation.

QUESTION 15

A network administrator notices that a few virtual machines run slowly every morning. To troubleshoot the issue the administrator needs to analyze the total traffic sent I virtual machines. Which feature would the administrator use for troubleshooting?

 

A.

Virtual LANs

B.

Traffic Shaping

C.

NetFlow

D.

Port Mirroring

 

Correct Answer: D

Explanation:

This feature is similar to the port mirroring capability available on the physical switches. Network administrators can use this feature to troubleshoot any network related issues in the virtual infrastructure and monitor virtual_machine-to-virtual_machine traffic that is flowing on the same ESXi host. Network administrators use network analyzer tool, which captures traffic, along with the port mirror feature to perform monitoring and troubleshooting activities. In the physical network, depending on where the analyzer or debug tool is placed in the network, network administrators choose different port mirroring options. The following are some of the standard port mirroring options available on physical switches.

QUESTION 16

What does Storage DRS do to determine if a particular disk device is overburdened?

 

A.

Powers down the storage device.

B.

Monitors disk I/O latency on the shared storage devices.

C.

Takes a count of virtual machines on the storage device.

D.

Reads the data on the storage devices.

 

Correct Answer: B

QUESTION 17

Which feature of vSphere networking restricts the inbound and outbound network bandwidth of a group of virtual machines?

 

A.

Differentiated Services Code Point

B.

NetFlow

C.

Traffic Shaping

D.

Port Mirroring

 

Correct Answer: C

Explanation:

Traffic Shaping

Allows you to restrict the inbound and outbound network bandwidth of a group of virtual machines.

QUESTION 19

What is the name of the logical volume that vSphere 6.x uses to store virtual machines files?

 

A.

Virtual Volume

B.

Datastore

C.

Logical Unit Number (LUN)

D.

Raw Device Mapping (RDM)

 

Correct Answer: B

 

 

QUESTION 20
