Quick Answer
The answer is 2. With FTT=2, the vSAN maximum host failures with fault domains is exactly 2, because the storage policy’s failure tolerance directly caps the number of simultaneous host or domain failures the cluster can survive, regardless of how fault domains are configured. Fault domains simply isolate failures to separate physical boundaries, but they do not increase the tolerance set by the policy; FTT=2 means the VM’s data is replicated or erasure-coded to withstand up to two failures across any combination of hosts or domains. On the VMware Certified Professional Data Center Virtualization VCP-DCV exam, this is a common trap—candidates often mistakenly add fault domain counts to FTT, but the correct logic is that fault domains enforce placement, not tolerance. A useful memory tip: “FTT sets the line, fault domains define the fence.”
This VCP-DCV practice question tests your understanding of configure and manage vsphere storage. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A vSAN cluster has two fault domains. What is the maximum number of host failures that can be tolerated if the cluster is configured with a storage policy that sets 'Number of failures to tolerate' to 2?
2
FTT=2 allows tolerance of 2 host failures.
1
Why wrong: FTT=1 tolerates 1 failure; FTT=2 tolerates 2.
3
Why wrong: 3 exceeds the configured FTT value.
4
Why wrong: 4 exceeds the configured FTT value.

Correct answer & explanation
2
With FTT=2, the VM can survive up to 2 host failures regardless of fault domains. Fault domains ensure that failures are isolated, but the FTT value directly sets the tolerance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Why it's wrong here
4 exceeds the configured FTT value.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the VCP-DCV exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
