VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 37

An architect is designing a vSphere environment for a customer based on the following information:
✑ The vSphere cluster will have three hosts only due to budget considerations.
✑ A database cluster (node majority) consisting of three virtual machines will be running on the vSphere cluster.
Which two recommendations can the architect make so that the customer achieves the highest level of application availability while taking into consideration operational resiliency? (Choose two.)

Answer options

• A. Create VM-VM anti-affinity rules
• B. Set das.respectvmvmantiaffinityrules to false
• C. Create VM-Host anti-affinity rules
• D. Disable vSphere HA during maintenance
• E. Set das.ignoreinsufficienthbdatastore to true

Correct answer: A, B

Explanation

Creating VM-VM anti-affinity rules (Option A) is essential for preventing virtual machines that are part of the same cluster from running on the same host, thus ensuring higher availability. Setting das.respectvmvmantiaffinityrules to false (Option B) allows for more flexibility in VM placement, which can be beneficial in a resource-constrained environment. The other options don't directly enhance application availability or could negatively impact it.
