How many SFP28 port-groups do Aruba 8325 CX switches have?

Question

Options

• A12 port-groups of 4 ports each
• BOne port-group of 48 ports
• C4 port-groups of 8 ports each
• D4 port-groups of 12 ports

• A
  3% (2)
• B
  8% (5)
• C
  2% (1)
• D
  87% (53)

Explanation

Option D is correct because the Aruba CX 8325 switch has 48 SFP28 ports organized into 4 port-groups of 12 ports each (4 × 12 = 48 total). These port-groups matter for understanding how the switch allocates shared resources like buffers and forwarding logic.

Why the distractors are wrong:

• A (12 groups of 4): The math yields 48 ports, but the grouping structure is inverted - the switch uses 4 larger groups, not 12 smaller ones.
• B (one group of 48): The total port count of 48 is correct, but they are not treated as a single monolithic port-group; they are divided into distinct groups for resource management.
• C (4 groups of 8): This gives only 32 ports total, which doesn't match the 8325's 48-port SFP28 capacity.

Memory tip: Think "4 dozen" - just like a dozen equals 12, the 8325 has 4 port-groups of 12, making 4 × 12 = 48 SFP28 ports. The "48" in the model name (8325-48Y8C) is your anchor.
