The correct answer is A. Enable Unicast Routing. To enable in-band management in Cisco ACI, allowing APICs and fabric switches to be reachable from the in-band network, unicast routing must be enabled on the associated bridge domain.
Question
Refer to the exhibit. The engineer is planning to configure in-band management for the Cisco ACI fabric. The goal is to allow the network operators to reach the Cisco APIC servers and fabric switches from the in-band network. Which configuration must be applied on the bridge domain to accomplish these goals?

Why each option
To enable in-band management in Cisco ACI, allowing APICs and fabric switches to be reachable from the in-band network, unicast routing must be enabled on the associated bridge domain.
Enabling Unicast Routing on a bridge domain allows the configured bridge domain's subnet to act as a default gateway for endpoints, facilitating IP reachability and routing within and outside the bridge domain, which is essential for in-band management access. This feature allows the APIC and fabric switches to be part of the routable network.
Setting the scope to 'Shared between VRF' makes the bridge domain subnet accessible across VRFs, but it doesn't inherently enable routing within the bridge domain itself for in-band management.
Making an IP address primary is a detail for subnet configuration but does not enable the fundamental routing capability required for in-band management.
This option is a duplicate of A and is correct for the same reason.
