Which command list satisfies configuring an SVI on an Aruba CX switch with VLAN 25, IPv4 address 10.105.43.1/24, IPv6 address fd00:5708::f02d:4df6/64, and VRF eng, using the least number of commands?

• A. vrf eng
• B. vlan 25
• C. interface vlan 25
• D. ip address 10.105.43.1/24 and ipv6 fd00:5708::f02d:4df6/64

Answer: (C)

Configuring an SVI starts by entering the VLAN’s interface context. The SVI is the Layer 3 representation of that VLAN, so all IP addressing and VRF binding for the SVI are done while you’re in interface vlan 25. Without entering this specific interface context, the IP addresses and VRF won’t attach to the SVI. So, the essential first step is to go into interface vlan 25. From there you can apply the IPv4 address, the IPv6 address, and bind the SVI to the VRF eng. The other options don’t place you in the correct configuration scope on their own: creating a VRF alone doesn’t create the SVI, creating the VLAN alone doesn’t create the SVI, and assigning addresses without being in the SVI context wouldn’t attach them to any interface.
