QUESTION 121

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 122

A functional requirement ____________.

 

A.

specifies what the system should do

B.

is a detail that happens to be true but has not been tested or verified

C.

specifies how the system should behave

D.

is an attribute that can prevent the completion of the project

 

Answer: A

Explanation:A functional requirement states something the system should do (for example, the system should process transactions). A nonfunctional requirement states how the system should behave (for example, the system should update its performance metrics every 5 seconds). An assumption is a detail that happens to be true but has not been tested or verified is an assumption, and a risk is an attribute that can prevent ta project from being completed.

 

 

QUESTION 123

The swap file must always be stored with the other virtual machine files.

 

 

 

VMware VDCD510 : Practice Test

 

A.

True

B.

False

 

Answer: B

Explanation:A virtual machine’s swap file can be stored separately on a local or shared datastore. This is a good option if you are replicating storage to another location and do not wish to replicate files that are not needed at the replicated site.

 

 

QUESTION 124

Mean time between failures (MTBF) is the ____________.

 

A.

point to which data has to be recovered after a failure

B.

amount of time it takes to recover a system from a failure

C.

plan to restore a system after a failure

D.

anticipated amount of time until a solution component will fail

 

Answer: D

Explanation:MTBF is the agreed upon amount of time it takes to recover a system from failure.

 

 

QUESTION 125

You are a VMware consultant working at a small managed-services company that has won a contract with a large Company A to host its test and dev platform, with the chance on annual review to host its production platform.

 

Although you have been engaged early in the project, because of business requirements, the budget for the project has already been combined with another DR project for another Company

B.The thought process for this decision is that, if needed, the test systems from Company A have a lower requirement in the unlikely event of Company B having a DR event.

All the items have been bought and are to be delivered. Your role is to take the equipment provided and construct, develop, and implement a scalable working vSphere platform.

 

The requirements stated are:

 

Company A test machines must be provided with sufficient resources for BAU. Company B systems must be made available with minimum impact to Company

 

A.

The RTO for Company A is seven days, with an RPO of one month. Company B’s RTO is 1 hour, and its RPO is 15 minutes.

 

The use of a shared infrastructure used in this way is a constraint to the project.

 

 

A.True

B.

False

 

Answer: A

Explanation:An item from the current state analysis that would restrict or change a design choice is potentially a constraint. These factors can limit the design and in some cases prevent the realization of the project vision.

 

 

QUESTION 126

Which of the following VMware vSphere functionality can help control real-time storage issues?

 

A.

Storage DRS

B.

Storage I/O control

 

Answer: B

Explanation:Storage I/O control can be used to monitor and ensure the amount of I/O at contention time. This is based on real-time stats and requires a support storage system. Storage DRS uses an average of I/O usage.

QUESTION 127

Which of the following could be considered a single point of failure for storage?

 

A.

Using RAID 5 instead of RAID 10

B.

Using single-port HBAs in an ESXi host

C.

Using a dual-port HBA in an ESXi host

D.

Not using jumbo frames

 

Answer: C

Explanation:Using a dual-port HBA can result in a single point of failure if the HBA malfunctions, taking out both ports. It is better to use two single-port HBAs.

 

 

QUESTION 128

VMware HA in vSphere 5.0 cannot survive more than five primary host failures. Thus, hosts should be physically placed in different racks, where possible, to avoid substantial impact.

 

A.

True

B.

False

 

Answer: B

Explanation:This was true for VMware HA solutions prior to version 5. vSphere 5 can withstand multiple failures and uses a master/slave topology with a reelection process.

 

 

QUESTION 129

Which design is created first?

 

A.

Conceptual design

B.

Physical design

C.

Logical design

 

 

 

VMware VDCD510 : Practice Test

D.

None of the above

 

Answer: A

Explanation:A conceptual design is a high-level overview of the suggested system. The conceptual design is created first and is usually the starting point for the logical design.

 

 

QUESTION 130

To balance IOPS and capacity within a datastore cluster, which of the following technologies should be implemente

d?

 

A.

vMotion

B.

High Availability

C.

Storage I/O control

D.

Storage DRS

 

Answer: D

Explanation:Storage DRS will automatically migrate powered-on VMs to datastores within a storage cluster in order to balance the capacity and IOPS among member datastores.
