Exam 300-620 topic 1 question 77 discussion

Actual exam question from Cisco's 300-620

Question #: 77
Topic #: 1

A Solutions Architect is asked to design two data centers based on Cisco ACI technology that can extend L2/L3, VXLAN, and network policy across locations. ACI
Multi-Pod has been selected. Which two requirements must be considered in this design? (Choose two.)

A. ACI underlay protocols, i.e. COOP, IS-IS and MP-BGP, spans across pods. Create QoS policies to make sure those protocols have higher priority.
B. A single APIC Cluster is required in a Multi-Pod design. It is important to place the APIC Controllers in different locations in order to maximize redundancy and reliability.
C. ACI Multi-Pod requires an IP Network supporting PIM-Bidir.
D. ACI Multi-Pod does not support Firewall Clusters across Pods. Firewall Clusters should always be local.
E. Multi-Pod requires multiple APIC Controller Clusters, one per pod. Make sure those clusters can communicate to each other through a highly available connection.

A is not correct, altho COOP, IS-iS and MP-BGP spans across pods. this is a standard behavior which you dont have to worry about , so its not a matter of consider this as a requirement, is how it works. Have said that, you dont have to create QoS policies to achieve the requirements in the question per se. C - You must enable PIM-Bidir in the IPN in order to L2 BUM traffic pass between PODs, otherwise the L2 extension will face some issues when talk to each other POD.

altho COOP, IS-iS and MP-BGP spans : No - it does not span pods. They run separate instances of that.

Correct answers are BC Multipod is with only a single APIC cluster - multisite requires multiple clusters. "The entire network hence runs as a single large fabric from an operational perspective; however, ACI Multi-Pod introduces specific enhancements to isolate as much as possible the failure domains between Pods, contributing to increase the overall design resiliency. This is achieved by running separate instances of fabric control planes (IS-IS, COOP, MP-BGP) across Pods." https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c11-737855.html
