QUESTION 191

You are a VMware consultant for a large enterprise running VMware vSphere 4.1. You are reviewing the upgrade documentation created to take the company to version 5.X of the software. The upgrade has several requirements, including the following:

 

Minimize the impact to the business applications Do a full rollback, if required, for any issues not foreseen by the project team

 

You notice in the documentation that the upgrade to VMFS 5 is mentioned as being nondisruptive and having zero impact on the technical solution. Is this technically correct?

 

A.

Yes

B.

No

 

Answer: B

Explanation:In this example, a VMFS 5 upgrade cannot be rolled back without extra scratch space and without using storage vMotion. These things could add extra I/O load on the systems and affect the first requirement.

QUESTION 192

During an upgrade of VMware vSphere 4.1 to vSphere 5.0, several virtual machines appeared to have lost network configuration. What is the possible cause of the issue?

 

A.

DHCP server not available

B.

Incorrect order of upgrade implementation steps

C.

Incorrect drivers.

 

Answer: C

Explanation:This can be experienced when migrating from a virtual machine hardware level and have an old version of VMware tools installed. The guest operating system may not understand the hardware and may create or lose information such as the MAC address and network settings. By upgrading VMware tools first and then upgrading the hardware the correct drivers and software are present for a non-impacting upgrade.

 

 

QUESTION 193

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 194

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 195

How do you understand and predict the resources available for VMware HA to meet specific project requirements?

 

A.

Configure the appropriate admission control policy

B.

Disable admission control policy

 

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 196

High Availability (HA) can prevent virtual machine downtime.

 

A.

True

B.

False

 

Answer: B

Explanation:HA restarts virtual machines when an ESXi host crashes. HA can reduce downtime, but it cannot prevent it.

 

 

QUESTION 197

Best practices should always be followed.

 

A.

True

B.

False

 

Answer: B

Explanation:Best practices are recommendations based on practical standards collected by VMware and should always be used unless company business rules or functional requirements prevent their use.

 

 

QUESTION 198

Infrastructure qualities are guiding design considerations that can be used ___________.

(Choose two)

 

 

 

VMware VCAP5-DCD : Practice Test

 

A.

in the absence of project requirements

B.

instead of project requirements

C.

in addition to project requirements

 

Answer: AC

Explanation:Good design should meet the project requirements and consider the properties of assumed platform design. Protecting data requires that a system be available and manageable, that it have good performance, and that it be easy to recover and be secure. Chapter 3, What Makes a Good Choice for Virtualization, and What Is a Good Design?

 

 

QUESTION 199

A nonfunctional requirement is similar to a(n) _______.

 

A.

constraint

B.

functional requirement

C.

risk

D.

assumption

 

Answer: A

Explanation:A constraint is an attribute that may limit a design choice. A nonfunctional requirement is a behavior of the system, which may also limit design choices. A functional requirement is something the system must do. An assumption is something that is decided to be true, without testing or verification. A risk is an attribute that can prevent a project from being completed.

 

 

QUESTION 200

Which of the following could be considered a single point of failure for storage?

 

A.

Using RAID 5 instead of RAID 10

B.

Using single-port HBAs in an ESXi host

 

 

 

VMware VCAP5-DCD : Practice Test

C.

Using a dual-port HBA in an ESXi host

D.

Not using jumbo frames

 

Answer: C

Explanation:Using a dual-port HBA can result in a single point of failure if the HBA malfunctions, taking out both ports. It is better to use two single-port HBAs.
