Explanation

Option A is correct because the Aruba CX 10000 features twelve SFP28 port-groups, each containing four ports - meaning breakout or speed settings are applied at the group level, affecting all four ports within that group together. Options B and D are wrong because they invert or consolidate the grouping structure (the CX 10000 doesn't bundle ports into large single groups of 12 or one all-encompassing group). Option C is wrong because port-groups are a fundamental part of how the CX 10000 manages its high-density SFP28 interfaces. For the exam, remember "12×4" - think of a dozen eggs in four-packs: twelve groups, four ports apiece.
