QUESTION 151

A network design has a requirement to have five total networks that are physically separated from one another.

 

The design requires that there be no single points of failure on the network. Based on this information, how many network adapters are needed?

 

A.

5

B.

2, with the use of VLANs

C.

1

D.

10

Since there is a requirement that physical separation is required for the five different networks, VLANs will not satisfy the design. To ensure that there is no single point of failure, each virtual switch will require 2 adapters per virtual switch–for a total of 10.

 

 

QUESTION 152

An activeassive storage array should be configured with the fixed multipathing policy.

 

A.

True

B.

False

 

Answer: B

Explanation:An activeassive array will have only one active path at a time. An array like this should be configured with the MRU multipathing policy. An activective array has multiple active paths and should be configured with round-robin or fixed-multipathing policies.

 

 

QUESTION 153

Which of the following is not a reason to use virtualization?

 

A.

Save money

B.

Improve system performance

C.

Save time

D.

Make disaster recovery easier

 

Answer: B

Explanation:Administrators often feel compelled to virtualize their server infrastructure for reasons such as the following:

Save time–Administering virtualized servers over physical servers can save a huge amount of time.

Save money–Any way you measure it, virtualization comes out as a cost-saving proposition; dollars are saved in less administrative time, fewer infrastructure requirements, and less energy utilization.

Simplify management–Virtualization enables the use of advanced features such as resource optimization, high availability, and point-in-time snapshots of servers. Recover from disaster–Having a reliable disaster recovery plan is essential for ensuring business continuity. Virtualization offers hardware independence and decreased recovery time after a disaster or failover.

 

 

QUESTION 154

A multitier website has an RTO of 4 hours and an RPO of 15 minutes. The database crashes at 5 p.m. and causes the website to be unavailable. Which of the following is true? (Select all that apply.)

 

A.

The website must be restored by 5:15 p.m.

B.

The website must be restored by 9 p.m.

C.

At restore time, the data must be correct from at least from 4:45 p.m.

D.

At restore time, the data must be from at least 1 p.m.

 

Answer: BC

 

 

QUESTION 155

A ______________ design requires IP addresses and specific hardware selections.

 

A.

conceptual

B.

physical

C.

logical

D.

None of the above

 

Answer: B

Explanation:A conceptual design is a high-level overview of the suggested system. Logical designs show how subsystems interconnect or communicate. No attempt is made to select vendors or map out physical products; rather, the logical design shows how the suggested components align together. A physical design puts specific components and settings into place. It lists items such as vendor products, IP addresses, and specific communication protocols. A physical design is a blueprint of an architecture.

QUESTION 156

The VMware hot add and hot plug functionality is most useful for a(n) __________ scaling approach.

 

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 157

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?

 

 

 

VMware VDCD510 : Practice Test

 

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 158

vSphere cluster functionality such as DRS and HA does not need to be part of a validation plan. This kind of documentation is only concerned with guest VM workload validation, not platform-wide validation.

 

A.

True

B.

False

 

Answer: B

 

 

QUESTION 159

In the project life cycle, who defines the vision?

 

A.

The IT architect

B.

The software vendor

C.

The business

 

Answer: C

 

 

QUESTION 160

A platform has an RPO of 4 hours. The platform crashes at 2 p.m. Which of the following is correct?

 

 

 

VMware VDCD510 : Practice Test

 

A.

The platform must be ready for users to access by 6 p.m., with data versions from at least from 10 a.m.

B.

The platform must be ready for users ASAP, with data versions from at least 10 a.m.

C.

The platform must be ready for users to access by 6 p.m., and the data age is unknown from the RTO.
