QUESTION: 1
When designing a storage platform, which of the following should be considered as part of the
overall design?

A. Capacity
B. I/O requirements of the applications to be supported
C. Disk latency tolerance
D. Growth rate
E. Al of the above

Answer(s): E
Explanation:
A storage platform logical design requires in-depth analysis of factors that can affect
applications.In the case of storage, aspects that relate to the physical layer--such as the amount
of usable space required for services; the size, number, and speed of disks; and how fast the
data is being produced--could have a substantial impact to the storage platform.

QUESTION: 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(s): 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 wil not traverse the ESXi host's physical
network interfaces. This wil 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
