NEW QUESTION # 49
In a Cisco ACI Multi-Site fabric, the Inter-Site BUM Traffic Allow option is enabled in a specific stretched bridge domain. What is used to forward BUM traffic to all endpoints in the same broadcast domain?
- A. egress replication on the source leaf switches
- B. ingress replication on the spines in the destination site
- C. egress replication on the destination leaf switches
- D. ingress replication on the spines in the source site
Answer: D
Explanation:
In a Cisco ACI Multi-Site fabric, when the Inter-Site BUM Traffic Allow option is enabled in a specific stretched bridge domain, ingress replication on the spines in the source site is used to forward Broadcast, Unknown unicast, and Multicast (BUM) traffic to all endpoints in the same broadcast domain. This method ensures that BUM traffic is efficiently replicated across the fabric, reaching all relevant endpoints without overwhelming the network with unnecessary traffic4.

NEW QUESTION # 58
A company must connect three Cisco ACI data centers by using Cisco ACI Multi-Site. An engineer must configure the Inter-Site Network (ISN) between the existing sites. Which two configuration steps must be taken to implement the ISN? (Choose two.)
- A. Configure BIDIR-PIM on all ISN routers.
- B. Configure OSPF on subinterfaces on routers that are directly connected with spine nodes
- C. Configure OSPF on all ISN routers.
- D. Configure encapsulation VLAN-4 between the routers and spine nodes.
- E. Configure ISN site extension on Cisco routers in the network
Answer: A,B
Explanation:
For the ISN implementation between Cisco ACI data centers using Multi-Site, OSPF must be configured on subinterfaces for dynamic routing, and BIDIR-PIM must be set up on all ISN routers for efficient bidirectional multicast traffic routing.

NEW QUESTION # 64
Which PIM version must be configured in the Inter-Pod Network to allow broadcast, unknown unicast. and multicast flooding between Cisco ACI pods?
- A. Source Specific Multicast
- B. Bidirectional PIM
- C. PIM sparse mode
- D. PIM dense mode
Answer: C
Explanation:
Protocol Independent Multicast sparse mode (PIM-SM) is designed for efficient routing to multiple receivers in a multicast group across an inter-pod network (IPN). PIM sparse mode is best suited for environments where receivers are dispersed because it allows for explicit join messages to control the flow of traffic. This makes it ideal for scenarios where broadcast, unknown unicast, and multicast flooding between Cisco ACI pods is required.

Answer: A
NEW QUESTION # 67
An engineer is implementing the Cisco ACI fabric but is experiencing loops detected from endpoints. When the issue was investigated, it was discovered that the packets are received with the same source IP address but from different leaf switch ports. The engineer must prevent the issue from happening in the future and make sure that the port is brought back up if it was disabled due to the loop discovered. Which set of actions must be taken to meet these requirements?
- A. Enable the enforce endpoint check and set the Rouge EP detection interval
- B. Enable reverse path forwarding and set the Hold Interval
- C. Enable the rogue endpoint and set the Error Disabled Recovery Policy
- D. Enable the remote endpoint limit and set the Interface override
Answer: C
Explanation:
To address loops detected from endpoints in a Cisco ACI fabric, the engineer should enable the rogue endpoint feature and set the Error Disabled Recovery Policy. This will allow the system to detect rogue endpoints causing loops and automatically recover the port if it was disabled due to the loop detection2.
