QUESTION 81

Which of the following describes the anticipated time until a solution component may fail?

 

A.

Recovery time objective

B.

Recovery point objective

C.

Mean time between failures

 

Answer: C

Explanation:The recovery time objective (RTO)–also known as the return to operation–is the amount of time it takes to restore a service after a failure has taken place. The recovery point objective (RPO) is the point in time to which the system needs to be restored following a failure. The MTBF is the amount of time a component is predicted to fail and can be used with operational management or design concepts.

 

 

QUESTION 82

VMware VDCD510 : Practice Test

Active discovery methods may impact the platform used for monitoring.

 

A.

True

B.

False

 

Answer: A

Explanation:There are two types of discovery methods: active and passive. Active discovery methods can run processes that are detrimental and can impact a system.

They normally require an agent.

With passive discovery methods, data is obtained in a non-impact, non-intrusive manner, with no agents.

Obtaining and interpreting/presenting data such as this normally requires more experience.

 

 

QUESTION 83

You have been asked to design a system with the following VMware functionality enabled:

 

R001: VMware HA must be functional.

R002: VMware SRM can be used between two sites for DR processes. R003: You must be able to see all hosts from a single pane of glass.

 

From these requirements:

 

A.

A vSphere 5.0 VCSA can provide an acceptable solution.

B.

A vSphere 5.0 Windows-based vCenter can provide an acceptable solution.

C.

The requirements cannot be met.

 

Answer: B

Explanation:The VCSA can function with VMware SRM. However, for SRM functionality, both sites require a vCenter installation. This would limit the choice of single-glass-pane management to Linked mode. A Linked mode installation requires Microsoft technology in the ADAM instance, and thus eliminates the VCSA choice.

QUESTION 84

A number of factors determine how many physical adapters are needed in a host design.

Which of the following is not one of them?

 

A.

Virtual machine size

B.

Amount of bandwidth required

C.

Security requirements

D.

Hardware fault tolerance

 

Answer: A

Explanation:Virtual machine size has no effect on the network.

 

 

QUESTION 85

High Availability (HA) can prevent virtual machine downtime.

 

A.

True

B.

False

 

Answer: B

Explanation:HA restarts virtual machines when an ESXi host crashes. HA can reduce downtime, but it cannot prevent it.

 

 

QUESTION 86

In which type of VLAN does adding and removing the VLAN tag occur at the virtual switch?

 

A.

Virtual switch tagging

B.

VLAN trunking

C.

Virtual guest tagging

D.

External switch tagging

 

 

 

VMware VDCD510 : Practice Test

 

Answer: C

Explanation:Virtual guest tagging occurs when the guest operating systems inside the virtual machines adds the VLAN tags the network traffic.

 

 

QUESTION 87

A design calls for 10 virtual machines, each with 2 GB of RAM, to be located on a single VMFS datastore. Only 5 virtual machines will be powered on at one time. If the virtual machines are
using default resource settings, how much space on the datastore will be utilized by swap files?

 

A.

20 GB

B.

10 GB

C.

No swap files will be created.

D.

None of the above

 

Answer: B

Explanation:By default, the swap file is the same size as the available memory of a VM. The swap file is created when you power on a virtual machine and removed when you power it off. With 5 virtual machines powered on and with each virtual machine having an available memory setting of 2 GB, 10 GB of space will be used for the swap files.

 

 

QUESTION 88

VMware HA may not restart all guest workloads if _______________.

 

A.

admission control policy is disabled

B.

the resources are fragmented between nodes in the cluster and DRS is not in fully automated mode

C.

the master ESXi node has crashed

 

Answer: B

VMware VDCD510 : Practice Test

 

Explanation:

An admission control policy tells VMware HA how to calculate the resources it needs to reserve for a cluster. It uses a combination of memory and CPU reservation configuration or, if no configuration exists, a default low reservation.

 

 

QUESTION 89

The vCenter is an example of a(n) _____ discovery tool.

 

A.

active

B.

passive

 

Answer: B

Explanation:There are two types of discovery methods: active and passive. Active discovery methods can run processes that are detrimental and can impact a system.

They normally require an agent.

With passive discovery methods, data is obtained in a non-impact, non-intrusive manner, with no agents.

Obtaining and interpreting/presenting data such as this normally requires more experience.

 

 

QUESTION 90

A project vision _______________.

 

A.

is the required endpoint of a project–the purpose for completing the process

B.

can be achieved after several iterations of a project life cycle

C.

both of these are correct

 

Answer: C

Explanation:The project vision indicates the final state the platform should be in. It is the business-led objective, which provides value and incorporates the infrastructure qualities.
