Implementing Cisco Application Centric Infrastructure (DCACI) — Question 217

An engineer must attach an ESXi host to the Cisco ACI fabric. The host is connected to Leaf 1 and has its gateway IP address 10.10.10.254/24 configured inside the ACI fabric. A new firewall is attached to Leaf 2 and mapped to the same EPG and BD as the ESXi host. The engineer must migrate the gateway of the ESXi host to the firewall. Which configuration set accomplishes this goal?

Answer options

• A. Disable unicast routing. Configure IP address 10.10.10.254/24 on the ACI BD.
• B. Disable unicast routing. Define IP address 10.10.10.254/24 on the firewall.
• C. Enable unicast routing. Configure IP address 10.10.10.254/24 on the ACI EPG.
• D. Enable unicast routing. Set IP address 10.10.10.254/24 on the firewall.

Correct answer: B

Explanation

The correct answer is B because disabling unicast routing allows the firewall to take over the gateway role for the ESXi host, and configuring the IP on the firewall is necessary for it to serve as the gateway. Options A and C do not achieve the migration since they either involve configuring the IP on the ACI BD or EPG instead of the firewall. Option D incorrectly suggests enabling unicast routing, which is not required in this scenario.
