A.

True

QUESTION 32

An organization is considering buying hosts that have one three-port NIC rather than buying hosts that have three one-port NICs. Is this a good idea? Why or why not?

 

A.

This is a good idea; one three-port NIC means fewer PCI slots.

B.

This is a good idea; one card is cheaper than three.

C.

This is not a good idea; one card translates to a single point of failure.

D.

This is not a good idea; three-port NICs are expensive

 

Answer: C

Explanation:If the one three-port NIC fails, you will usually lose all three ports on the NIC. It would be a better solution to use three one-port NICs instead. You lose one card, and you lose only one port.

 

 

QUESTION 33

VMware fault tolerance requires a cluster-aware application within the guest workload.

 

A.

True

B.

False

 

Answer: B

A requirement in a se

rver consolidation project states: “The consolidation ratio must be as high as possible.” This has resulted in a lower number of larger-capacity hosts in the vSphere HA cluster. Which of the following is true?

 

A.

QUESTION 35

Infrastructure qualities are guiding design considerations that can be used ___________.

(Choose two)

 

A.

in the absence of project requirements

B.

instead of project requirements

C.

in addition to project requirements

 

Answer: AC

Explanation:Good design should meet the project requirements and consider the properties of assumed platform design. Protecting data requires that a system be available and manageable, that it have good performance, and that it be easy to recover and be secure.

QUESTION 37

You are a VMware architect working at a company where a business application is being rolled out. Based on conversations with the business, you establish that the RTO requirement is 2 hours, and the RPO requirement is 3 hours. Consider a situation in which the VMware platform is out of service following multiple hardware issues. The application dropped from service at 2 p.m. To meet the application business SLA, which of the following is true?

 

A.

When the application is brought online, the data must be from a version as of 4 p.m.

B.

When the application is brought online, the data must be from a version as of 11 a.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 38

The infrastructure qualities are attributes you can use to ensure that major aspects are considered to help with good design processes. What are the infrastructure qualities?

 

A.

RTO, RPO, and MTBF

B.

C.

Capacity, change control, security

, DR, and supportability

Consider leaving about 20% of a datastore available for _____________.

 

A.

larger virtual machines

B.

vMotion

C.

snapshots

QUESTION 40

Vendor-best practices can be used to guide ______________.

 

A.

configuration and design choices in the absence of project requirements

B.

configuration and design choices in addition to project requirements

C.

both these answers are correct

 

Answer: C

Explanation:A best practice is normally based on experience with a successful implementation. By using these configurations, known issues could possibly be avoided. Best practices should not replace project requirements but can be used as a starting point, as long as the project requirements are satisfied.
