What is a consideration when specifying a Dial Home suppression time for a Dell Unity XT storage array?

Question

Options

• AShould be set between 1 and 32 hours
• BCan be lengthened or shortened
• CThe time zone where the array is located
• DCan be enabled at any time

• A
  94% (29)
• C
  3% (1)
• D
  3% (1)

Explanation

Option A is correct because Dell Unity XT enforces a strict constraint on the Dial Home suppression window: it must be set to a value between 1 and 32 hours, making this the primary consideration when configuring it. This bounded range ensures suppression is used for finite maintenance windows and not left open-ended.

Why the distractors are wrong:

• B is misleading - while you can adjust the duration, the fact that it "can be lengthened or shortened" is trivially true of almost any time setting and ignores the enforced 1–32 hour boundary, which is the actual constraint.
• C is irrelevant - suppression duration is a relative time window, not a scheduled clock time, so the array's time zone has no bearing on configuring it.
• D is a distractor that sounds reasonable but isn't a meaningful consideration - the real constraint is the valid range, not when you're permitted to enable it.

Memory tip: Think "1 to 32" as "one shift to a day and a third" - suppression covers at least one hour of work but caps before it can span two full days, keeping Dell support in the loop reasonably quickly.
