QUESTION 51

A functional requirement in a design requires management, IP-based storage, vMotion, and virtual machine traffic to be physically separated. Which option best fulfills the functional requirement?

 

A.

Using a single virtual switch, applying VLANS for each traffic type, and configuring the physical adapters to use different physical switches

B.

Using distributed virtual switches

C.

Using a different virtual switch for each type of traffic and having all network adapters use the same physical switch

D.

Using a different virtual switch for each type of traffic and having the physical adapters use different physical switches

 

Answer: D

VMware VDCD510 : Practice Test

 

Explanation:

VLANs can be used to logically separate network traffic. Separate virtual switches will physically separate the traffic on the ESXi host, but using a single physical switch introduces a single point of failure. The best answer is D: Using different physical switches will allow for redundancy.

 

 

QUESTION 52

Which of the following is not considered vSphere network traffic?

 

A.

IP storage

B.

VM network

C.

Storage vMotion

D.

vMotion

 

Answer: C

Explanation:vSphere network traffic includes VM network, vMotion, IP storage, FT traffic, and management network traffic.

 

 

QUESTION 53

The difference between the beginning of a project and the vision is also known as the ____________.

 

A.

current state analysis

B.

gap state analysis

C.

upstream relationship

D.

downstream relationship

 

Answer: B< /span>

Explanation:By reviewing the current configuration of a system and mapping the final status of components as described in the vision, the business identifies the gap between the two. A

gap state analysis is a review of the items or tasks that are required to progress between the stages. Such an analysis is useful in creating milestone plans, implementation orders, and so on.

 

 

QUESTION 54

You are working on a virtual guest design for the deployment of a critical business application. The software vendor has provided you with very few application requirements for projected workloads. Which of the following scaling approaches does this describe?

 

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 55

Part of your design includes updating VMware tools and virtual hardware to a newly updated vSphere 5.1 architecture. What is the best method for updating tools and hardware?

 

 

 

VMware VDCD510 : Practice Test

 

A.

Manually update each virtual machine

B.

Don’t bother updating the VMs; the new version of hardware and tools are not necessary

C.

Use Update Manager to update all the virtual machines at once

D.

Use Update Manager to help update the virtual machines in groups, as maintenance windows allow

 

Answer: D

Explanation:Using Update Manager is the best way to upgrade multiple virtual machines in an automated fashion. You would not want to update them all at once because it would be time-consuming and would require a lot of resources and lots of reboots. As a result, there might not be enough time to finish within a maintenance window.

 

 

QUESTION 56

Which of the following diagrams which may be included in project documentation shows a system’s components and how they could affect/depend on each other?

 

A.

Logical diagram

B.

Entity relationship diagram

C.

Physical diagram

 

Answer: B

Explanation:An entity relationship diagram is a form of logical diagram than can be used to map service component dependencies. It is independent of the hardware used for a solution.

Chapter 2, Presenting the Data Gathered

 

 

QUESTION 57

Based on the information in the high-level design extract from question 2, what storage protocol is unsuitable?

 

 

 

VMware VDCD510 : Practice Test

 

A.

NFS

B.

iSCSI

C.

FC

 

Answer: A

Explanation:The requirements state that the application uptime requirements would not be met if using vSphere HA alone. vSphere HA would invoke a restart of guest virtual machines after at least 10 seconds.

VMware fault tolerance would meet the uptime requirements; a failover would result in zero downtime of the application. This technology can be used only with VMFS; therefore, NFS cannot be used in this design.

Chapter 4, NetWork – Logical and Physical Design to allow applications to flow

 

 

QUESTION 58

You develop a physical storage design after you develop a logical storage design.

 

A.

True

B.

False

 

Answer: A

Explanation:A logical design is used to create a physical design. The logic and relationships should be capable of being deployed using any vendor.

 

 

QUESTION 59

Which of the following is an advantage of a scaled-out architecture?

 

A.

Fewer larger hosts means less hardware.

B.

Larger servers come with more bells and whistles, like completely redundant hardware.

C.

Smaller hosts translate to less time needed to recover using HA.

D.

Larger servers are cheaper.

 

 

 

VMware VDCD510 : Practice Test

 

Answer: C

Explanation:In a scaled-out architecture, the cluster is configured with many smaller hosts rather than fewer large hosts. Because of this, when an ESXi host crashes in a scaled-out cluster, you lose a smaller percentage of your cluster, which translates to fewer virtual machines crashing, which translates to faster recovery times.

 

 

QUESTION 60

A validation plan can be used to gather further requirements.

 

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 th

ese 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).
