QUESTION 141

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.

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 142

An entity relationship diagram shows the physical attributes of a solution.

 

A.

True

B.

False

 

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 the solution.

 

 

QUESTION 143

Which quality of a good design deals with backup and restoration?

A.

Availability

B.

Manageability

C.

Performance

D.

Recoverability

 

Answer: D

Explanation:Recoverability deals with recovering from a component or system outage with minimal data loss, in accordance with an organization’s RTO and RPO.

 

 

QUESTION 144

The size of a host can affect the business impact in the event of a VMware HA event.

 

A.

True

B.

False

 

Answer: A

Explanation:The size and number of VMs running on a system can affect the impact of a system failure. For example, a larger per-host configuration with a smaller number of hosts per cluster would normally have a larger consolidation ratio; however, in the event of a failure, more guest VMs would be restarted, and this would be more likely to impact more applications.

 

 

QUESTION 145

You are working on a virtual guest design for the deployment of a critical business application. The software vendor has provided you with some projected workloads. One of the project requirements is to ensure that business application performance is guaranteed. Which of the following would be the best approach for guest configuration?

 

A.

Configure the virtual guest with a reservation, as specified, as the minimum requirement for the application to run.

B.

Configure the virtual guest with a reservation, as specified, as the projected initial

workload requirement.

 

Answer: B

Explanation:Allocated resources are shown in the guest operating system and are not guaranteed. The amount depends on the unreserved resources available at the time. Assuming no functionality issues, you can configure a production application to be guaranteed its projected workload, and the system should deliver. Without a reservation, there is potential for a performance impact if there is contention.

 

 

QUESTION 146

A ____________ is an iterative process used to define a technical solution.

 

A.

constraint

B.

best practice

C.

logical design

D.

design methodology

 

Answer: D

Explanation:A design methodology is an iterative process used to create a technical design.

 

 

QUESTION 147

An upstream relationship is a logical object or component that has dependency on other items in a solution.

 

A.

True

B.

False

 

Answer: A

Explanation:In an upstream relationship, a logical object or component has a dependency on other

items in the solution. For example, a service running on an application server requires an Active Directory user account to be authenticated. The application service must be started after the Active Directory service. Therefore, the application server has an upstream relationship with the Active Directory service.

In an downstream relationship, a logical object or component does not have a dependency on other items in the solution. For example, say that a multisite web server crashes. The web tier hosting multiple websites will crash; however, the downstream objects such as the database server will continue to function. Backend processes that are dependent on the downstream objects from the web servers can continue to function.

 

 

QUESTION 148

The design process involves creating a conceptual design, using the conceptual design to aid in creating the logical design, and then using the logical design to assist in creating the physical design.

 

A.

True

B.

False

 

Answer: A

Explanation:A conceptual design brings forth the scope of the project. A logical design starts to show the relationship between components, without selecting specific equipment. The physical design is the exact drawing of the design, as intended.

 

 

QUESTION 149

As a designer, you must either use a predictive or adaptive approach to creating virtual machines. You cannot use a combination of the two approaches.

 

A.

True

B.

False

 

Answer: B

VMware VDCD510 : Practice Test

 

Explanation:

In some instances, a combination of the two approaches might be best.

 

 

QUESTION 150

VMware HA respects vApp startup order.

 

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.
