A storage administrator must enable NAS service for a Dell Unity XT380 equipped with 12 16- Gbps FC front-end ports. The data center network has only 10 Gbps Ethernet SFP+ ports available. How many…

Options

• A8
• B0
• C16
• D4

• A
  74% (28)
• B
  13% (5)
• C
  5% (2)
• D
  8% (3)

Explanation

Option A (8) is correct because the Dell Unity XT380 has a fixed number of front-end I/O module slots across its dual Storage Processors. With 12 × 16 Gbps FC ports already installed (consuming FC I/O module slots), the remaining available slots can accommodate 10 GbE SFP+ I/O modules - each providing 2 Ethernet ports - yielding exactly 8 additional 10 GbE ports for NAS service.

Why the distractors are wrong:

• B (0) is wrong because the system can support Ethernet ports for NAS alongside existing FC ports - the slots are not all consumed by FC.
• C (16) exceeds the remaining slot capacity; this number might tempt candidates who confuse it with the total 16 Gbps FC port count already installed.
• D (4) is a per-SP answer - it represents the correct count for one Storage Processor only, forgetting that the Unity XT380 has two SPs contributing to the total.

Memory tip: On Unity XT dual-SP systems, always calculate available ports per SP first (remaining slots × ports per module), then double for the full system. If a choice looks like a single-SP answer, that's a classic distractor.
