QUESTION 11

You are considering the correct option for a VMware HA cluster admission control policy. The system is a hosted platform, and for business reasons, reservations will not be used.

Which of the following statements is correct?

 

A.

The only admission control policy possible is based on failover host.

B.

A default slot size will be used in place of reservations.

C.

The percentage-based admission control policy should be used.

 

Answer: B

Explanation:An admission control policy tells VMware HA how to calculate the resources it needs to reserve for a cluster. It uses a combination of memory and CPU reservation configuration or, if no configuration exists, a default low reservation.

A.

True

B.

False

 

Answer: A

Explanation:An admission control policy tells VMware HA how to calculate the resources it needs to reserve for a cluster. It uses a combination of memory and CPU reservation configuration or, if no configuration exists, a default low reservation.

QUESTION 14

You are a VMware architect employed to design and build application environments and the underlying platform for a software development company. The company is using a “devops” approach and has engaged with you at the beginning of the first planning meeting/pre-sprint.

 

The software has yet to be written. However, you have some high-level specifications that are subject to change at each of the early meetings.

The ______ is more logical for virtual machine sizing.

 

A.

predictive sizing approach based on current software

B.

adaptive sizing approach

 

Answer: B

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 15

What are t

he main types of storage? (Choose two)

 

A.

Fibre Channel

B.

local storage

C.

VMFS

D.

shared storage

 

Answer: BD

Explanation:From a VMware platform design perspective, the storage is agnostic. Logically, there are two types of storage: local and shared.

QUESTION 16

A project vision in some cases may not be achieved due to constraints, risks, and other project factors. However, a project vision is required to guide a project throughout the life cycle.

 

A.

True

B.

False

 

Answer: A

Explanation:The technical design process enables a platform designer to work in a methodical way and with others who have similar objectives. The vision is the endpoint–the environment or situation whereby the business would ideally like to be following the process.

QUESTION 17

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 requi

rement 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 application 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 18

Information gathered during the current state analysis include the number of sites, servers, or devices; a list of applications and their dependencies; current usage; and known issues.

 

A.

True

B.

False

 

Answer: A

Explanation:Data such as the following may be gathered for a current state analysis:

Number of sites, servers, or devices

A list of applications and their dependencies

Current use and capacity

Known issues (for example, a specific piece of software is not supported in a virtualized platform, an application requires certain hardware to run) Forthcoming projects and future growth plan (for example, Will extra capacity be needed soon? Is a critical point in the business year approaching?) Licensing, support, and maintenance information

Business standards, policies, and compliance

information

 

 

QUESTION 19

You are a VMware technical contact for an application development project. The system consists of a multitier application. In addition to you, the project team consists of three developers and a project manager. You are required to create various environments for different stages of the SDLC. The developers will be developing in silos on various hardware (laptops, Windows 7 desktops, vSphere hosted). Which of the following delivery methods would be the easiest to manage and deploy?

 

A.

Create the virtual servers using an in-house template and export each VM and present the server OVFs to each developer for copying and importing.

B.

Create servers for an environment and place them within a vApp object, export the vApp object as OVF files, and present the OVF files to the dev team for editing and importing.

C.

Create servers for an environment and place them within a vApp object, export the vApp object as an OVF file, and present the file to the dev team for copying and importing.

 

Answer: C

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.

 

 

QUESTION 20

You are a VMware architect designing a solution for a client with an existing site who wishes to build a disaster recovery site. The operations manager has presented some information in the kickoff meeting. The company has 1,000 VMs, and the average VM has the following specs:

 

18 GB memory

 

2 vCPU

 

100 GB

 

The company already has an existing vendor relationship with a hardware vendor and would like to keep the existing storage solution roadmap in place. The following requirements are stated:

 

RTO: 15 minutes

 

RPO: 15 minutes

 

Uptime: 99.99%

 

The existing vendor relationship is a ______________.

 

A.

risk to the project

B.

constraint

C.

vision

 

Answer: B

Explanation:

An assumption could impact your design. It is good to ensure that project team and wider business are aware of assumptions and that they are agreed and validated as part of the design consideration process.
