What is the maximum hierarchical Snapshot level, for both LUNs and file systems, on Dell Unity XT storage system?
The correct answer is C. 10. On Dell Unity XT, the maximum hierarchical Snapshot level is 10 for both LUNs and file systems, making C correct. This is a hard platform limit - nesting snapshots beyond 10 levels deep is not supported, regardless of available capacity. Why the distractors are wrong: A (20)…

Explanation
On Dell Unity XT, the maximum hierarchical Snapshot level is 10 for both LUNs and file systems, making C correct. This is a hard platform limit - nesting snapshots beyond 10 levels deep is not supported, regardless of available capacity.
Why the distractors are wrong:
- A (20) and D (32) are plausible-sounding round numbers but exceed the actual platform ceiling - Dell does not support snapshot chains that deep on Unity XT.
- B (16) may seem familiar because 16 appears in other storage contexts (e.g., some replication or RAID parameters), but it is not the snapshot hierarchy limit.
Memory tip: Think "10 = top" - 10 levels is the top of the Unity XT snapshot hierarchy. The number 10 also matches how snapshot trees are typically visualized as a single-digit depth, keeping management practical.
