In Aruba CX VSX configuration, which statement about VRRP and Active Gateway on a VLAN is true?

• A. VRRP and Active gateway are mutually exclusive on a VLAN
• B. VRID is set automatically as SVI vlan id
• C. VRIDs need to be non-overlapping with VRRP
• D. VRRP and Active Gateway can be configured on a single VLAN for interoperability

Answer: (A)

In VSX, gateway redundancy for a VLAN is provided by either VRRP or Active Gateway, not both. VRRP creates a virtual IP that is owned by a master device, with a backup device ready to take over if the master fails. Active Gateway designates which switch in the VSX pair owns the gateway for that VLAN, and failover occurs by transferring gateway control to the other switch. If both mechanisms were configured on the same VLAN, you’d get conflicting gateway ownership and routing state, leading to unpredictable traffic paths. So the correct statement is that VRRP and Active Gateway are mutually exclusive on a VLAN. If you choose VRRP, use VRRP exclusively for that VLAN; if you choose Active Gateway, disable VRRP for that VLAN.
