VMware vSAN 8.x Administrator — Question 60

An architect is designing a new VMware Cloud Foundation (VCF) solution. During the discovery workshops, the customer explained that the solution will initially be used to host a single business application and some internal management tooling. The customer provided the following background information:

• The business application consists of two virtual machines.
• The business application is sensitive to changes in its storage IO.
• The business application must be available during the company’s business hours of 9am - 5pm on weekdays.

The architect has made the following design decisions in response to the customer’s requirements provided during discovery:

• The solution will use the VCF consolidated architecture model.
• A single cluster will be created consisting of six ESXi hosts.

Which design decision should the architect include in the design to mitigate the risk of impacting the business application?

Answer options

• A. Use resource pools to apply CPU and Memory reservations on the business application virtual machines.
• B. Use Anti-Affinity Distributed Resource Scheduling (DRS) rules on the business application virtual machines.
• C. Replace the vSAN shared storage exclusively with an All-Flash Fibre channel shared storage solution.
• D. Perform ESXi host maintenance activities outside of the stated business hours.
• E. Implement FTT=6 for the business application virtual machines.

Correct answer: D

Explanation

Choosing option D is correct because performing maintenance activities outside of business hours ensures that the application remains available during critical times. The other options either do not directly address availability during business hours or could introduce unnecessary complexity without guaranteeing the application's performance and uptime.
