  The solution must support the ability to migrate workloads between hosts within a cluster.

  The solution must support resource management priorities.

  The solution must support the ability to connect virtual machines directly to LUNs.

  The solution should use existing IPv4 based network infrastructure.

  There is no budget for additional physical hardware.

  Which two design decisions could the architect make to meet these requirements? (Choose two.)

  A. The ESXi hosts will leverage Fibre Channel (FC)

  B. The ESXi hosts will leverage NFS 3

  C. The ESXi hosts will leverage Fibre Channel over Ethernet (FCoE)

• Question 73:

  An architect is reviewing a physical storage design. The customer has specified that storage DRS will be used for ease of operational management for capacity and performance.

  Which recommendation should the architect include in the design?

  A. Create smaller datastores to balance space with Storage DRS

  B. Use a larger number of storage profiles (varied disk speeds and RAID levels) to improve performance

  C. Create larger datastores to balance space with Storage DRS

  D. Create more datastores within each Storage DRS cluster to balance space and performance

  Correct Answer: D

• Question 74:

  The Chief Information Security Officer (CISO) for an organization is concerned about the security posture of the operating system images that are used for the provisioning of their Software-as-a-Service (SaaS) applications. The organization is in a growth period. The organization is opening a new data center to

  launch its next phase of new SaaS-based solutions.

  The DevOps team currently creates encrypted virtual machine (VM) templates that are used for various

  operating systems and adds these to the vSphere inventory. The DevOps team already uses a published

  content library and has been granted a role with the ability to add and delete library items.

  The following requirements have been noted:

  Impacts to the DevOps team's operational processes must be kept to a minimum.

  The DevOps team must be able to regularly check out a copy of the image for updates and check in a new

  version of the image.

  Images must be synchronized from the primary data center to the new data center.

  Which three recommendations should the architect make to design a content library solution that will meet

  these requirements? (Choose three.)

  A. Clone virtual machines as VM templates to the published content library

  B. Create a subscribed library from the published library and synchronize Open Virtualization Format (OVF) templates on-demand

  C. Create a subscription and publish VM templates to a subscribed content library

  D. Create a subscribed library from the published library and synchronize Open Virtualization Format (OVF) templates automatically

  E. Clone virtual machines as Open Virtualization Format (OVF) templates to the published content library

  F. Update the role for the DevOps team with new privileges

  Correct Answer: BEF

• Question 75:

  An architect is tasked with planning the design of a new vSphere environment. When commissioned, this environment will be used to migrate an existing set of virtual machines.

  An inventory of the existing infrastructure, including configured vCPU, RAM and storage sizes has been provided.

  In order for each virtual machine to be migrated, which two data sources with peak and average utilization data are required for sizing? (Choose two.)

  A. %Ready

  B. Disk Write latency

  C. CPU

  D. Ballooned memory

  E. IOPS

  Correct Answer: BE

• Question 76:

  An architect makes the design decision to install ESXi on embedded and resilient 8 GB SD cards. What is the impact of this design decision?

  A. Host profiles must be used for this kind of installation

  B. Scratch partition would need to be created on the external storage

  C. The size of the SD cards is too small and the installation will fail

  D. The vSphere Auto Deploy feature must be enabled on vCenter Server

  Correct Answer: A

• Question 77:

  An architect is designing a new vSphere environment to meet the following requirements:

  The environment must support 5,000 virtual machines.

  The environment will be built initially using 350 hosts.

  Which vCenter Server appliance deployment size should the architect specify for the design?

  A. Large

  B. Small

  C. Tiny

  D. Medium

  Correct Answer: A

• Question 78:

  An architect is designing a new greenfield environment with 600 ESXi hosts in an automated fashion. The engineering department already has a PXE Boot server, TFTP server, and DHCP server set up with an NFS mount for their current Linux servers.

  The architect must be able to demonstrate and meet a security requirement to have all infrastructure processes separated.

  Which recommendation should the architect make for the ESXi host deployment?

  A. Request an isolated network segment to use and dedicate it to Auto Deploy functions

  B. Ask the business to expand the engineering environment to service the virtual environment as well

  C. Request a common shared network with flexible security measures to accommodate different auto deployment options

  D. Deploy each ESXi host individually and document it to satisfy security requirements

  Correct Answer: C

• Question 79:

  An architect is designing a new vSphere environment with the following resources:

  600 vCPU

  5,760 GB RAM

  Average resource usage is:

  60 vCPU

  1,152 GB RAM

  The design must meet the following requirements:
