What are two characteristics of a durability component in vSAN? (Choose two.)

Question

Options

• ABetter Performance
• BFaster resynchronization
• CFaster snapshot creation
• DBetter Storage utilization
• EBetter Availability

• A
  6% (3)
• B
  90% (47)
• C
  2% (1)
• D
  2% (1)

Explanation

vSAN durability components act as temporary protective placeholders when a host failure occurs, tracking changed data (via a change log/bitmap) so that only modified blocks need to be resynced rather than the full object - this is why B (Faster resynchronization) is correct. They also maintain the required fault-tolerance level of the storage object during the failure window, keeping data accessible and protected, which is why E (Better Availability) is correct.

The distractors fail because: A (Better Performance) is wrong - durability components are a resiliency mechanism, not a performance optimization; C (Faster snapshot creation) is unrelated to durability components entirely; and D (Better Storage utilization) is actually the opposite of true - durability components temporarily consume extra space as overhead.

Memory tip: Think "D.A.R.E. to survive failures" - Durability = Availability + Resync speed. When a host goes down, vSAN dares to keep your data available and resyncs fast.
