Question 1

An architect has 50 ESXi hosts to deploy and DHCP servers are not allowed on any network. Which automated host deployment method should the architect use?



Answer : C

'Running a script is an efficient way to deploy multiple ESXi hosts' with an unattended installation. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.esxi.install.doc/GUID-00224A32-C5C5-4713-969A-C50FF4DED8F8.html


Question 2

A customer requires the use of data encryption to ensure data is not accessible when a drive is removed from the primary storage platform. However, there is also a requirement to use deduplication and compression against all workloads in order to conserve space.

Which solution meets the customer requirements?



Answer : D

Array-based encryption provides the same benefits as SEDs (self-encrypting drives), in that the drive shows no readable data once it is removed from the array. That means drives don't need to be physically destroyed when they are removed, which brings cost, security and environmental benefits


Question 3

A customer has a database cluster with 40/60 read/write ratio and a high IOPs requirement with no contention on an all-flash vSAN cluster.

Which two storage settings should be configured for best performance? (Choose two.)



Answer : B, C


Question 4

A customer has six hosts available in a cluster. When running at full capacity, all virtual machines can be run on two hosts.

How many hosts can the customer place into maintenance mode at the same time while still providing N+2 resiliency to the cluster?



Answer : A


Question 5

As part of a requirements gathering workshop, the customer provides the following requirements for the design of a new greenfield virtual infrastructure:

Some applications have a latency that must be less than 5 minutes.

The solution must be able to support a workload growth rate of 10% per year.

Which requirement classification is being gathered for the design documentation?



Answer : A


Question 6

An architect is finalizing the design for a new vCenter Server High Availability deployment.

What is one thing the architect must document in the design?



Answer : B

vCenter HA uses SSH keys for password-less authentication between the Active, Passive, and Witness nodes. The authentication is used for heartbeat exchange and file and data replication. To replace the SSH keys in the nodes of a vCenter HA cluster, you deactivate the cluster, generate new SSH keys on the Active node, transfer the keys to the passive node, and activate the cluster.

Question 7

An architect is designing a new vSphere platform for a customer to meet the following requirements:

The platform must be deployed into five physically separate sites.

The sites are spread across multiple regions.

Some sites require more than one vCenter Server.

The platform must provide an administrator with the ability to access virtual infrastructure components across all sites from a single management tool instance.

Which single sign-on (SSO) design recommendation will meet these requirements?



Answer : A

Use an SSO domain across all vCenter Server instances 'The platform must provide an administrator with the ability to access virtual infrastructure components across all sites from a single management tool instance' Having a single SSO domain will achieve this.

'The platform must provide an administrator with the ability to access virtual infrastructure components across ALL SITES from a SINGLE management tool instance' this is Linked mode.
