Master the VMware Certified Specialist - vSAN exam with our comprehensive Q&A collection. Review questions by topic, understand explanations, and build confidence for exam day.
Strategies to help you tackle VMware Certified Specialist - vSAN exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for VMware Certified Specialist - vSAN
The witness component contains only metadata about the vSAN object and is used to maintain quorum and availability decisions when data components are distributed. It does not store actual data, only information about the object's state. Option A is incorrect because witnesses do not store data copies. Option C is incorrect as caching is handled by cache tier devices, not witnesses. Option D is incorrect because encryption is handled by the encryption layer, not witness components.
RAID-6 (Erasure Coding) with FTT = 2 is the correct answer as it provides tolerance for two host failures while using less storage than mirroring (1.5x overhead vs 3x for RAID-1). RAID-6 requires a minimum of 6 hosts, which is satisfied. Option A uses 3x storage overhead. Option B (RAID-5) can only tolerate one failure. Option D creates a hybrid configuration but is more complex and still uses more space than RAID-6.
High network latency in vSAN health checks indicates a networking issue that must be investigated first. This includes checking for proper VLAN configuration, network congestion, physical cable issues, or misconfigured vmkernel adapters. Option A addresses storage distribution but won't fix network latency. Option C relates to data processing, not network transport. Option D addresses capacity/performance but won't resolve network latency issues between hosts.
RAID-5 erasure coding in vSAN requires a minimum of 4 hosts. This configuration provides 3+1 erasure coding (3 data components and 1 parity component) allowing for one host failure tolerance. Option A (3 hosts) is the minimum for a basic vSAN cluster but insufficient for RAID-5. Options C and D exceed the minimum requirement; 6 hosts is the minimum for RAID-6.
A two-node vSAN cluster requires an external witness host (or witness appliance) to maintain quorum and provide tie-breaking capabilities. The witness is essential for determining which node remains operational during split-brain scenarios. Option A is incorrect as vSAN management is integrated with vCenter. Option C is not mandatory for vSAN operation. Option D describes a stretched cluster which is a different architecture.
