NEW QUESTION # 44
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.)

- B. Set das.ignoreinsufficienthbdatastore to true
- C. Disable vSphere HA during maintenance
- D. Create VM-Host anti-affinity rules
- E. Set das.respectvmvmantiaffinityrules to false
Answer: A,E
Explanation:
A) Create VM-VM anti-affinity rules - A VM-VM affinity rule specifies whether selected individual virtual machines should run on the same host or be kept on separate hosts.
https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.resmgmt.doc/GUID-94FCC204-115A-4918-9533-BFC588338ECB.html
B) Set das.respectvmvmantiaffinityrules to false - Determines if vSphere HA enforces VM-VM anti-affinity rules. The default value is "true" and rules are enforced even if vSphere DRS is not enabled. In this case, vSphere HA does not fail over a virtual machine if doing so violates a rule
