QUESTION 71

An application has an SLA which states that the application must be restored within 12 hours, with no more than 10 minutes of data loss. This means the application has an RTO of 10 minutes and an RPO of 12 hours.

 

A.

True

B.

False

 

Answer: B

Explanation:The RTO is the amount of time until a crashed application should be back online. The RPO is the tolerated amount of data loss.

 

 

QUESTION 72

You are a VMware designer working on virtualizing a business application. The SLA specifies that the RTO requirement is 4 hours, and the RPO requirement is 9 hours. After months of successful use, the system crashes at 1 p.m. To meet the project SLA, which of the following is true?

 

A.

The application must be brought online and be accessible to users by 10 p.m.

B.

The application must be brought online and be accessible to users by 5 p.m.

 

Answer: B

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.

 

 

QUESTION 73

According to HA best practices, which of the following admission control policies is most appropriate for a cluster of hosts with virtual machines of very different memory and CPU reservations?

 

A.

CPU and Memory % Configuration

B.

Number of Hosts Tolerate

C.

Failover Host

 

Answer: A

 

 

QUESTION 74

A best practice can change over time.

 

A.

True

B.

False

 

Answer: A

Explanation:A best practice is based on experience with delivering a solution. A new product will have limited best-practice information except for vendor- or vendor-partner-based recommendations. The longer a technology is used in a community, the more potential success; therefore, best practices can change over time.

A guest VM should be sized using ____________. (Choose two)

 

A.

minimum applications specifications

B.

initial workload

C.

anticipated workloads

Answer: AC

Explanation:Allocated resources are shown in the guest operating system and are not guaranteed. The amount depends on the unreserved resources available at the time. Assuming no functionality issues, you can configure a production
application to be guaranteed its projected workload, and the system should deliver. Without a reservation, there is potential for a performance impact if there is contention. Chapter 5, Virtual Machines–From the Design Perspective

A.

must be achieved

B.

can be set as aspirational but may never be achieved

 

Answer: A

QUESTION 79

Which metric displays the amount of time, in milliseconds, it takes for a virtual CPU to get processing time on a physical CPU?

 

A.

CPU Wait

B.

Ballooning

C.

CPU Ready

D.

pCPU

 

Answer: C

Explanation:

 

 

VMware VCAP5-DCD : Practice Test

 

CPU Ready is a metric that can be viewed using performance charts on the Web client or the vSphere client that shows how long a virtual CPU had to wait for a physical CPU to become available.

 

 

QUESTION 80

Which of the following type of discovery methods used in state-analysis techniques is more likely to affect application or server performance.

 

A.

Active

B.

Passive

C.

Both A and B

 

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.
