A storage administrator has added multiple resources to a single density-based Host I/O Limit policy for the following storage resources: - LUN A:25GB - LUN B:25 GB - LUN C:50 GB - Density-Based…

Question

Options

• A2000
• B500
• C60
• D1000

• A
  84% (26)
• B
  3% (1)
• C
  3% (1)
• D
  10% (3)

Explanation

Option A (2000 IOPS) is correct because a density-based limit applies the IOPS rate per GB of total storage, not per LUN or per policy. Adding the three LUNs gives 25 + 25 + 50 = 100 GB total, and 100 GB × 20 IOPS/GB = 2,000 IOPS.

Why the distractors are wrong:

• C (60) confuses density-based with a flat per-LUN limit - multiplying 3 LUNs × 20 IOPS ignores capacity entirely.
• D (1000) only accounts for the largest LUN (50 GB × 20 = 1,000), missing the other two.
• B (500) applies the rate to a single 25 GB LUN, as if only one resource were in the policy.

Memory tip: Think of "density" like density in physics - it's always rate × quantity (IOPS/GB × total GB). When multiple resources share one density-based policy, sum all their capacities first, then multiply by the density limit.
