VCP-DCV vSphere Architecture, Products and Solutions Practice Question
Which two of the following are required to deploy a vSphere cluster with vSphere HA and DRS? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Clock synchronization across all hosts (NTP)
Options A and C are correct. Clock synchronization (NTP) is required for vSphere HA master election and DRS recommendation consistency. Network connectivity for management traffic is required for host communication and vCenter management. Option B is incorrect because a single vCenter Server can manage both HA and DRS. Option D is incorrect because Active Directory is optional. Option E is incorrect because shared storage is not a prerequisite for HA or DRS; HA can use datastore heartbeats on any accessible storage, and DRS works with or without shared storage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Clock synchronization across all hosts (NTP)
Why this is correct
HA and DRS require synchronized time for proper operation.
- ✗
A minimum of two vCenter Server instances
Why it's wrong here
Only one vCenter Server is required for a cluster.
- ✓
Network connectivity between hosts for management traffic
Why this is correct
HA and DRS need management network communication.
- ✗
An active Directory service for authentication
Why it's wrong here
AD is optional for vSphere clusters.
- ✗
Shared storage accessible by all hosts in the cluster
Why it's wrong here
HA/DRS can work without shared storage (e.g., vSAN is shared, but not required).
