Question 14

Which feature should be disabled on a bridge domain when a default gateway for endpoints is on an external device instead of a Cisco ACI bridge domain SVI?

Accepted Answer

Unknown unicast flooding should be disabled on a bridge domain when a default gateway for endpoints is on an external device instead of a Cisco ACI bridge domain SVI. This is because unknown unicast flooding can cause traffic to be flooded to all endpoints on the bridge domain, which can lead to performance problems and security risks.

Question 17

An organization expands a Cisco ACI Multi-Pod from two to six pods and must ensure that the control plane scales. What should be configured in the IPN to ensure that BUM traffic is forwarded efficiently across the IPN?

Accepted Answer

BIDIR-PIM (Bidirectional Protocol Independent Multicast) is used to efficiently forward Broadcast, Unknown unicast, and Multicast (BUM) traffic across the Inter-Pod Network (IPN) in a Cisco ACI Multi-Pod environment. It helps in scaling the control plane by optimizing the distribution of multicast traffic.

Question 18

What does the VXLAN source port add to the overlay packet forwarding when it uses the hash of Layer 2, Layer 3, and Layer 4 headers of the inner packet?

Accepted Answer

The VXLAN source port uses a hash of Layer 2, Layer 3, and Layer 4 headers to enable Equal-Cost Multi-Path (ECMP) routing, which allows for efficient load balancing across multiple paths in the network.
