NO.1 Storage DRS can be enabled and can balance I/O levels based on

A. real-time stats

B. historical stats

Answer: B

Explanation:

Storage DRS can balance I/O by using storage vMotion. This would be based on historical values for

a period of time. Storage DRS would make decisions based on these figures. If the system were

using realtime stats, the machines could potentially migrate a lot more. This could have an effect on

the latency figures for some systems. The larger historical sampling in storage DRS allows the system

to make a decision with limited risk of impacting I/O-unlike moving a virtual machine over and over

again. Chapter 4, Storage Design - The Logical & Physical Approaches

 

NO.2 You are the technical designer for a vSphere platform transformation project. After conducting

SME interviews and using various platform information-gathering methods, you have created a

high-level design document. This document specifies the following: Requirements: R1. The solution

must not have a single point of failure. R2. Production applications must not have an outage of

more than 10 seconds. R3. Data must be based in the UK. R4. There is a 7-year retention policy for

contracts. R5. Applications should support existing and developing workloads for the next 3 years'

growth. Spec of servers: Web 1 vCPU, 2 GB RAM, 100 GB storage App 1 vCPU, 4 GB RAM, 100 Gb

storage DB 2 vCPU, 16 GB RAM, 750 Gb storage At a late stage in the software development life

cycle of a production application developed in- house, an unfortunate issue was identified when the

application was deployed to the production vSphere cluster. The production core stacked switch has

capacity issues, and this is having a serious impact on all applications for which the switch is

providing network services. Within the test system, the application works as intended in the single

test VLAN and with a single-host configuration. Which of the following could be tried to help in this

situation, from a vSphere perspective? (Choose two)

A. Redevelop the application for a virtual platform

B. Place the application into a single-vApp network

C. Add DRS rules to keep network traffic within the same host, where possible

D. Configure network I/O control

Answer: B,D

Explanation:

If you limit the application traffic to a specific dedicated network (that is, a separate VLAN) and

using enforced DRS affinity rules, the application traffic will not traverse the ESXi host's physical

network interfaces. This will ensure that the impact of the application is minimized, while also

ensuring that the application itself is not limited. The application servers already have vCPU settings.

This suggests that the system has already being virtualized in both types of environments. Network

I/O control could be useful in the event of contention, but the role of a designer would be to plan to

prevent contention where possible;

other options would be more beneficial.

In addition, Requirement 5 specifies that the system should work with workloads over the next 3

years. Network I/O control would suggest contention very early in the platform history. Chapter 4,
