QUESTION 131

You have a requirement to create a three-tiered application as part of a virtual machine’s design. The requirement includes the ability to start up and shut down the tiers in a given order and to be able to ensure that the three-tiered application gets the resources it needs.

Which would be the best option?

 

A.

Put all the tiers in a resource pool and manage resources via the resource pool settings

B.

Create a vApp and place the three tiers in it. Configure the startup/shutdown options and configure resources via the vApp

C.

Ensure that all three tiers are on the same vSwitch and use the ESXi host VM startup and shutdown options

D.

Manage the three tiers as three separate virtual machines

Answer: B

Explanation:Of all these options, only a vApp can offer startup, shutdown, and resource control options.

 

 

QUESTION 132

A(n) _______ is a set of processes which proves that a design has been properly configured and that the design works as planned.

 

A.

validation plan

B.

implementation plan

C.

design blueprint

D.

none of the above

 

Answer: A

Explanation:A validation plan is used to ensure that a design is implemented and configured properly and to ensure that the design functions as intended.

 

 

QUESTION 133

What practice should not be considered when using IP-based storage?

 

A.

Using an isolated network for storage

B.

Using jumbo frames

C.

Placing the storage network on the physical switch as the management network

D.

Using a 10GbE network

 

Answer: C

Explanation:It is a good idea to keep the storage network physically isolated from all other networks. If this cannot be done, at least consider logically separating the storage network via a VLAN.

QUESTION 134

When considering scalability, the VCSA is not as effective as the vCenter installed on a Windows platform.

 

A.

True

B.

False

 

Answer: B

Explanation:The VCSA can scale to the same size of the Windows-based platform when using a remote database based on Oracle or DB2. Microsoft SQL, however, is not supported. The built-in database is a DB2 version, which is only supported for small platforms.

 

 

QUESTION 135

An installation guide should contain _____________. (Choose two)

 

A.

basic troubleshooting and baseline monitoring for verification purposes

B.

entry criteria or requirements

C.

justifications for design choices

D.

best practices.

 

Answer: AB

Explanation:An installation guide provides engineers a detailed reference and process to install and verify a solution. All relevant components and processes are detailed. It is also useful to include troubleshooting or known issues, if any were experienced during the development and test phases.

 

 

QUESTION 136

VMware VDCD510 : Practice Test

Which of the following could prevent a physical system from being converted to a virtual workload?

 

A.

The physical system uses legacy operating systems, such as Windows

B.

NT 4.

C.

The application running on the physical server is not supported in a virtual platform.

D.

The application has not been tested in a virtual platform.

 

Answer: B

 

 

QUESTION 137

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 138

Which design quality is concerned with creating an architecture that is easy to maintain and operate?

 

A.

Recoverability

B.

Security

C.

Availability

D.

Manageability

Answer: D

Explanation:When a system is manageable, the infrastructure is easy to maintain and operate.

 

 

QUESTION 139

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 identified 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?

 

 

 

VMware VDCD510 : Practice Test

(Choose two)

 

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.

QUESTION 140

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

 

A.

CP

U Wait

B.

Ballooning

C.

CPU Ready

D.

pCPU

 

Answer: C

Explanation: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.
