A storage administrator wants to have frequent snapshots of a LUN during production hours What is the minimum frequency configurable for a snapshot schedule of the LUN?

Question

Options

• A2 hours
• B15 minutes
• C30 minutes
• D1 hour

• A
  7% (3)
• B
  2% (1)
• C
  4% (2)
• D
  87% (39)

Explanation

On many enterprise storage platforms (such as Dell EMC Unity), the snapshot scheduler enforces a minimum interval of 1 hour between scheduled snapshots for a LUN, making D the correct answer. This limit exists to balance snapshot overhead with storage performance during production hours.

• A (2 hours) is wrong because it's less frequent than the minimum - you can schedule every 2 hours, but it's not the minimum (most frequent) option.
• B (15 minutes) is wrong because no standard LUN snapshot scheduler allows intervals that short; sub-hourly scheduling is not supported.
• C (30 minutes) is a common distractor since it sounds "frequent," but it falls below the 1-hour threshold the scheduler enforces.

Memory tip: Think of it as "1 Hour = 1 LUN snapshot minimum" - the scheduler won't let you go more granular than that for a production LUN schedule.
