QUESTION 161

A logical diagram illustrates how components relate to each other in a solution.

 

A.

True

B.

False

 

Answer: A

Explanation:A logical diagram can be used to show service components and how they relate to each other. A logical diagram is a high-level diagram that is independent of the hardware used for the solution.

 

 

QUESTION 162

A platform validation plan is primarily concerned with guest VM settings and application delivery rather than VMware platform functionality.

 

A.

True

B.

False

 

Answer: B

Explanation:A validation plan can range from a detailed test plan to high-level statements. It should not be subjective. The best validation is to place a platform under a typical test of what it will be faced with in the field –for example, having a simulated number of users go through a workflow (perhaps a website). A lot of these tasks vary with the type of application and are primarily application functionality based. In addition, platform or infrastructure metrics are

key for validation and for information to be used within the operational documentation (for example, troubleshooting guide, monitoring recommendations).

 

 

QUESTION 163

A recovery time objective (RTO) is ___________.

 

A.

the point to which data has to be recovered after a failure

B.

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

C.

the plan to restore a system after a failure

D.

an agreement with the customer on a predefined level of service

 

Answer: B

Explanation:RTO is the amount of time it must take to recover a system from failure.

 

 

QUESTION 164

You are a platform designer constructing a physical design from an existing approved logical design. Out of the vendor proposals, there are two proposed solutions that could be used. Which of the following options is the most important factor when making a decision?

 

A.

Community and vendor-based best practices

B.

Existing vendor relationships

C.

Project requirements

D.

Project budget

 

Answer: C

 

 

QUESTION 165

A physical adapter can belong to only one virtual switch.

A.

True

B.

False

 

Answer: A

Explanation:A physical adapter can be assigned to only one virtual switch. Once it is assigned, it no longer shows up on the available adapter list.

 

 

QUESTION 166

You are designing a vSphere 5 HA cluster. One of the requirements is to ensure full collection of log files in the event of an issue. Which of the following is correct? (Choose two)

 

A.

By default, ESXi logs are not persistent following reboots.

B.

The logs should be forwarded to a syslog server or vCenter dump collector.

C.

The ESXi logs are persistent through reboots.

 

Answer: AB

Explanation:By default, ESXi hosts do not store logs persistently through reboots. To ensure full visibility of logs, a syslog and/or vCenter dump collector is required for compliance and root cause analysis.

QUESTION 167

A validation plan does not validate _____________.

 

A.

the design

B.

system functionality

C.

that system requirements match the functionality of the design

D.

topics outside the scope of the design

Answer: D

Explanation:A validation plan should validate the design, should verify that the system operates in accordance with the functional requirements, and should ensure that all requirements are met.

 

 

QUESTION 168

You are a VMware technical consultant for an application development project. The system consists of a multitier application. The team consists of you, five developers, and a project manager. At the project kickoff meeting, you are tasked with creating the servers for each stage of the development life cycle the team is using: development, testing, staging, and production. During the meeting, you come to the conclusion that the technical specifications have yet to be defined or will likely change. Which of the following scaling approaches for guest workload design would be most appropriate?

 

A.

Adaptive

B.

Predictive

 

Answer: A

Explanation:There are two types of scaling approaches in virtual platforms: adaptive and predictive. Both approaches are usable; however, a designer must work out which is the best approach for each project.

The adaptive approach to guest virtual machine design is a major advantage that virtualization technology brings to a datacenter. It allows a guest virtual machine to be created initially on a few metrics or high-level requirements (such as a limited budget) and scaled (that is, grown, not shrunk) through the virtual machine life cycle. In many cases, this scaling can be performed hot/live without outage/downtime to the running applications. The predictive approach, on the other hand, requires more planning and research, and you must know the metrics before deployment. The advantage here is that once the virtual machine has been deployed, only application maintenance is required. The application requirements are known.

QUESTION 169

Which of the following will still function if vCenter crashes?

 

A.

HA

B.

DRS

C.

FT

D.

Storage DRS

 

Answer: A

Explanation:Although all the options listed require the vCenter Server for configuration, HA will work even if the vCenter Server crashes. For this reason, VMware recommends running the vCenter Server in a virtual machine so HA can provide the vCenter Server availability.

 

 

QUESTION 170

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.
