QUESTION 1

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:

I would like to clarify few things in this blog entry about the Port-mirroring feature that is available on vSphere Distributed Switch (VDS). 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, dependi
ng 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 2

Which two statements are true about local storage? (Choose two.)

 

A.

It requires a compatible Host Bus Adapter in the host.

B.

It requires a storage network to communicate with the host.

C.

It is a virtual storage.

D.

It is a direct-attached storage.

 

Correct Answer: AC

Explanation:

Local storage does not require a storage network to communicate with your host. You need a cable connected to the storage unit and, when required, a compatible HBA in your host.

Local Storage Stores virtual machine files on internal or directly connected external storage disks

QUESTION 3

After configuring Fault Tolerance for critical servers, an administrate notices that protected virtual machines run slower than usual. What is the reason for performance reduction of these virtual machines?

 

A.

Hosts have lower bandwidth for Fault Tolerance logging.

B.

Virtual machines are usually slow after Fault Tolerance logging.

C.

The storage space on the host is low.

D.

Virtual machines are running memory intensive applications.

 

Correct Answer: A

 

QUESTION 4

What are two features of a resource pool? (Choose two.)

 

A.

Controls the aggregate CPU and memory resources of the DRS cluster.

B.

Allocates available resources among the virtual machines.

C.

Consolidates workloads to reduce the power consumed by the cluster.

D.

Provides easy migration and monitoring.

QUESTION 5

How does Storage Replication handle data replication without a dedicated link between various storage sites?

 

A.

By using storage I/O control for replication of datastores.

B.

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

C.

By using volume level mirroring.

D.

By using storage vMotion.

 

Correct Answer: D

Explanation:

vSphere Storage vMotion Yes You can move the disk files of a replicated virtual machine on the source.
