Which does VOQ implement that is different from most typical campus switches?

Question

Options

• ALarge ingress packet buffers
• Bvsx
• CPer-port ASICs
• DLarge egress packet buffers

• A
  5% (2)
• B
  87% (34)
• C
  8% (3)

Explanation

VSX (Virtual Switching Extension) is the HPE Aruba-specific high-availability technology that VOQ-based switches implement, enabling active-active redundancy between two switches that appear as a single logical device - something not found on typical campus switches, which rely on traditional spanning tree or basic stacking.

Why the distractors are wrong:

• A (Large ingress packet buffers): While VOQ architecture does use ingress buffering, this alone is not the key differentiator being tested here - many enterprise switches have varying buffer configurations.
• C (Per-port ASICs): This is a hardware design detail present in various switch lines and is not a defining characteristic unique to VOQ switches.
• D (Large egress packet buffers): This describes traditional switch architectures - VOQ specifically moves buffering to the ingress side to prevent head-of-line blocking, so large egress buffers are the opposite of what VOQ does.

Memory tip: Think "V-S-X goes with V-O-Q" - both are HPE Aruba-specific technologies that appear together in the CX high-end switch line. If you see VOQ on an HPE exam, VSX is likely the paired concept being tested.
