Implementing Cisco Application Centric Infrastructure (DCACI) — Question 174

A network engineer must optimize a Cisco ACI multi-pod deployment. Both pods are using the same pod policy group. The customer requirement is to avoid inter-pod traffic loss in case of planned or unplanned spine reload. Which action accomplishes this goal?

Answer options

• A. Configure the COOP type as compatible in COOP Group Policy.
• B. Configure MACsec in the MACsec Fabric Interface Policy.
• C. Configure a lower IS-IS metric for redistributed routes in ISIS Policy.
• D. Configure all spines as Route Reflectors in the BGP Route Reflector Policy.

Correct answer: C

Explanation

Configuring a lower IS-IS metric for redistributed routes in the ISIS Policy ensures that routes are preferred during spine reloads, thus minimizing traffic loss. The other options either do not directly address the issue of traffic loss during spine reloads or are not applicable to the scenario described.
