VCP-DCV Configure and Manage vSphere Storage Practice Question
A vSphere administrator is planning to configure VMware vSAN. Which TWO requirements must be met for a vSAN cluster?
⚠ Common exam trap
It's easy for candidates to confuse vSAN's minimum requirement of 3 hosts with the common misconception that vSAN can run with 2 hosts (which requires a witness host for quorum), or they mistakenly think a dedicated 10 GbE network is mandatory, when vSAN can function on 1 GbE with proper configuration.
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
✓
Each host must have at least one SSD and one HDD for capacity.
VSAN requires at least one SSD (or NVMe) for the cache tier and one HDD (or SSD) for the capacity tier on each host to form a disk group. This hybrid or all-flash configuration is fundamental to vSAN's storage architecture, where the cache tier accelerates writes and reads, while the capacity tier provides persistent 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.
- ✗
A dedicated 10 GbE network for vSAN traffic.
Why it's wrong here
While recommended, 1 GbE can be used for vSAN.
- ✗
All hosts must have identical CPU models.
Why it's wrong here
vSAN does not require identical CPUs.
- ✓
Each host must have at least one SSD and one HDD for capacity.
Why this is correct
vSAN uses SSD for caching and HDD for capacity.
- ✓
A minimum of 3 ESXi hosts in the cluster.
Why this is correct
Standard vSAN requires at least 3 hosts.
- ✗
A shared storage array accessible by all hosts.
Why it's wrong here
vSAN uses local disks, not shared storage.
