QUESTION NO: 1

RTO and RPO requirements can have a direct impact on the size and number of virtual datastores used in a vSphere platform.

A. True
B. False

Answer: A

QUESTION NO: 2

You are a platform designer reviewing a colleague's design. Based on vSphere 5, the platform is designed to be scalable and provide continuous availability of the vCenter. The proposed design utilizes VMware FT. Does the design meet requirements?
A. Yes
B. No

Answer: B

Explanation:

VMware FT currently only supports 1vCPU. The vCenter requires 2vCPU and above, dependingon the location of the Microsoft SQL database.

QUESTION NO: 3

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 NO: 4

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

A. Fewer Larger hosts means less hardware to manage
B. Smaller hosts mean more DRS options
C. Smaller hosts translate to less time needed to recover using HA
D. Smaller servers are cheaper.

Answer: A

Explanation:

In a scaled-up architecture, Fewer servers are needed because each server can handle
morevirtual machines that what a typical scaled-out server can handle. So the cluster will require
fewer servers.

QUESTION NO: 5

A logical design includes basic subsystems that the design will use and data flow directions, but it
does not include specific hardware or settings details.
A. True
B. False

Answer: A

Explanation:

A logical design shows a high-level overview of the design without going through the details of
the design such as hardware and software selections and storage and network settings. The logical design isusually the starting point for the physical design.

QUESTION NO: 6

A gap state analysis is a review of the items or tasks required to progress from the current environment to the vision.

A. True
B. False

Answer: A

Explanation:

By reviewing the current configuration of a system and mapping the final status of components
asdescribed in the vision, the business identifies the gap between the two. A gap state analysis is
a review of theitems or tasks that are required to progress between the stages. Such an analysis
is useful in creatingmilestone plans, implementation orders, and so on.

QUESTION NO: 7

You are reviewing a vSphere platform design. The system is planning to use a virtual vCenter
server. Which of the following is not true if the vCenter fails when using this design?

A. DRS is unaffected.
B. VMware HA can protect and restart the vCenter.
C. The VCSA cannot be used.
D. vCenter must be configured in Linked mode.

Answer: A

Explanation:

DRS is controlled by the vCenter. vCenter invokes vMotion based on metrics. During the
periodwhere the vCenter is out of action, DRS is not functional.

QUESTION NO: 8

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: A,B

Explanation:

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

QUESTION NO: 9

As a platform designer, you have been asked to create a design for a vSphere 5 platform. Based
on existing capacity state analysis, the platform will require 30 hosts and 250 guest VMs. Due to
an existing vendor relationship with the enterprise, the preferred database for all datacenter
systems is Microsoft SQL 2008. Which of the following vCenter deployments can be used based
on this constraint?

A. VCSA with a remote Microsoft SQL 2008 database
B. Windows-based vCenter with a local Microsoft SQL 2008 database
C. VCSA with an embedded Microsoft database
D. Any of the above would meet the requirements.

Answer: B

QUESTION NO: 10

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 virtualizationtechnologybrings to a datacenter. It allows a guest virtual machine to be created initially on a few metrics or high-levelrequirements (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 mustknow 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.
