In a small Data Center two-tier topology what technology is used with VSX pair to provide redundancy for the default router?

Question

Options

• AHSRP
• BActive forwarding
• CActive gateway

• A
  3% (1)
• B
  3% (1)
• C
  95% (37)

Explanation

Active Gateway is the correct answer because it is HPE Aruba's VSX-native feature that assigns a shared virtual IP and MAC address to both VSX peers, allowing both switches to simultaneously serve as the default gateway for connected hosts - a true active-active redundancy model designed specifically for VSX deployments in two-tier Data Center topologies.

HSRP (A) is wrong because it is a Cisco-proprietary protocol; VSX is an HPE Aruba technology and does not use HSRP for gateway redundancy.

Active forwarding (B) is a distractor because it describes the general VSX behavior where both peers can forward traffic across the VSX LAG - it is a capability of VSX, not the specific mechanism that provides default gateway redundancy.

Memory tip: Think "Active Gateway → Gateway redundancy." In VSX, everything is active, so the gateway technology matches that theme - both peers actively answer ARP for the virtual IP, unlike HSRP's active/standby model.
