QUESTION 81

DRS and vMotion can help increase consolidation ratios.

 

A.

True

B.

False

 

Answer: A

Explanation:DRS can be configured for fully automated mode and can review performance statistics on hosts.

 

 

 

VMware VCAP5-DCD : Practice Test

 

Assuming that all workloads will not have the same peak period of time, you can load balance workloads across the hosts and reuse resources in different scenarios through the working day to increase consolidation ratios.

QUESTION 82

Which of the following are the infrastructure qualities?

 

A.

Availability, manageability, best practices, scalability, backup

B.

Availability, manageability, performance, recoverability, security

C.

CPU, memory, network, storage

D.

Management, virtual machine, compute, network, storage

 

Answer: B

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 83

Which virtual machine scaling approach requires the most planning and research before the VM is actually created?

 

A.

Comprehensive

B.

Predictive

C.

Adaptive

D.

Literal

 

Answer: B

Explanation:The predictive approach requires you to have a full understanding of how the application will utilize resources before the virtual machine is created. There will be no actions taken to

scale once the VM is complete. The advantage of this is that once the VM is complete, only periodic application maintenance is required.

 

 

QUESTION 84

You are VMware architect working at a large enterprise where a new VMware platform is being installed.

 

Based on conversations with the business, you establish that the RTO requirement is 8 hours, and the RPO requirement is 15 minutes. After months of successful use, the system crashes at 4 p.m. To meet the project SLA, _____________. (Choose two)

 

A.

the application must be brought online and be accessible to users by midnight.

B.

the application must be brought online and be accessible to users by 4:15 p.m.

C.

when the appl

ication is brought online the data must be from a version as of 3:45 p.m.

D.

when the application is brought online the data must be from a version as of 8 p.m. the night before.

 

Answer: AC

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 85

The VMware hot add and hot plug functionality is most useful for a(n) __________ scaling approach.

 

A.

adaptive

B.

predictive

 

Answer: A

VMware VCAP5-DCD : Practice Test

 

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 86

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

 

A.

active

B.

passive

 

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 87

VMware HA respects vApp startup order.

 

 

 

VMware VCAP5-DCD : Practice Test

 

A.

True

B.

False

 

Answer: B

Explanation:A vApp is a logical container of guest virtual machine objects. The use of a container provides the ability to use key management functionality, which can dramatically help a virtualized platform. Automation allows lots of VMs to be managed by fewer staff

. Although the objects have startup and shutdown automation features, VMware HA does not currently understand this feature; therefore, at present, a manual process should be used to restart applications in the event of a VMware HA event.

 

 

QUESTION 88

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 89

Options for running the vCenter Server include _____________.

 

A.

installed on a physical server.

B.

installed on a virtual machine.

C.

deploying the vCenter Virtual Appliance

D.

all of the above

 

Answer: D

VMware VCAP5-DCD : Practice Test

 

Explanation:

All of the listed options are supported.

 

 

QUESTION 90

You are the technical designer for a vSphere platform transformation project. After conducting SME interviews and using various platform information-gathering methods, you have created a high-level design document.

 

This document specifies the following:

 

Requirements:

 

R1. The solution must not have a single point of failure.

 

R2. Production applications must not have an outage of more than 10 seconds.

 

R3. Data must be based in the UK.

 

R4. There is a 7-year retention policy for contracts.

 

R5. Applications should support existing and developing workloads for the next 3 years’ growth.

 

Spec of servers:

 

Web 1 vCPU, 2 GB RAM, 100 GB storage

 

App 1 vCPU, 4 GB RAM, 100 Gb storage

 

DB 2 vCPU, 16 GB RAM, 750 Gb storage

 

At a late stage in the software development life cycle of a production application developed in-house, an unfortunate issue was ide

ntified when the application was deployed to the production vSphere cluster. The production core stacked switch has capacity issues, and this is having a serious impact on all applications for which the switch is providing network services. Within the test system, the application works as intended in the single test VLAN and with a single-host configuration.

 

Which of the following could be tried to help in this situation, from a vSphere perspective? (Choose two)

 

 

 

VMware VCAP5-DCD : Practice Test

 

A.

Redevelop the application for a virtual platform

B.

Place the application into a single-vApp network

C.

Add DRS rules to keep network traffic within the same host, where possible

D.

Configure network I/O control

 

Answer: BD

Explanation:If you limit the application traffic to a specific dedicated network (that is, a separate VLAN) and using enforced DRS affinity rules, the application traffic will not traverse the ESXi host’s physical network interfaces. This will ensure that the impact of the application is minimized, while also ensuring that the application itself is not limited. The application servers already have vCPU settings. This suggests that the system has already being virtualized in both types of environments. Network I/O control could be useful in the event of contention, but the role of a designer would be to plan to prevent contention where possible; other options would be more beneficial. In addition, Requirement 5 specifies that the system should work with workloads over the next 3 years. Network I/O control would suggest contention very early in the platform history.
