An engineer configured subnets on the external EPG called L3OUT_CORE. The external endpoints in the 10.1.0.0/24 subnet can reach internal endpoints, but the external endpoints in the 172.16.1.0/24 subnet are unreachable. Which set of actions enables the connectivity?

A. Delete both external EPG subnets. Create the 0.0.0.0/1 subnet.

B. Delete the external EPG subnet 0.0.0.128/1. Create the 128.0.0.0/1 subnet.

C. Delete both external EPG subnets. Create the 0.0.0.0/0 subnet.

D. Delete the external EPG subnet 0.0.0.0/0. Create the 0.0.0.0/128 subnet.

A customer is deploying a new application across two ACI pods that is sensitive to latency and jitter. The application sets the DSCP values of packets to AF31 and CS6, respectively.

In a Cisco ACI fabric, an endpoint moves between two leaf switches during a virtual machine migration. Which action does Cisco ACI take to minimize the impact to traffic during this event?

A. A new leaf switch updates a COOP database on the spine, which causes the old leaf switch to install a bounce entry.

B. A new leaf switch sends a COOP message to the Cisco APIC cluster to populate a new location of the endpoint.

C. A new leaf switch sends a COOP message directly to the old leaf switch to update it with new information about the endpoint move.

D. A new leaf switch floods GARP to every other leaf switch in the fabric, which advertises a new endpoint location to the fabric.

A network engineer implements an L3Out inside the Cisco ACI fabric. The engineer plans to connect a Cisco ACI leaf switch to a switch outside of the Cisco ACI fabric to exchange routes via a routing protocol.
