NEW 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?
- A. BIDIR-PIM
- B. MP-BGP
- C. spine headend replication
- D. MSDP
Answer: C
Explanation:
In a Cisco ACI Multi-Pod environment that is expanding, spine headend replication should be configured to ensure efficient forwarding of BUM (Broadcast, Unknown unicast, Multicast) traffic across the IPN (Inter-Pod Network). This configuration optimizes the control plane scaling and ensures that BUM traffic is handled effectively, maintaining network performance and stability.

- B. PBR node tracking
- C. Endpoint Dataplane Learning
- D. Direct Connect in the service graph template
Answer: C
Explanation:
PBR Node Tracking:
* Purpose: It is used to monitor the health and availability of endpoints within an Endpoint Group (EPG).
* Functionality: When configured, it allows for real-time health checks and traffic redirection based on endpoint status and network conditions.
* Benefits: Ensures traffic is directed to healthy endpoints, maintaining application performance and availability.
NEW QUESTION # 21
What is a design implication for Cisco ACI using an application-centric approach?
- A. One VLAN equals one EPG equals one bridge domain
- B. VLAN numbers are in the names of the bridge domain and EPG objects
- C. One EPG is mapped to multiple bridge domains
- D. Multiple VLANs and/or multiple EPGs are under one bridge domain
Answer: D
Explanation:
Using an application-centric approach in Cisco ACI means that multiple VLANs and/or multiple EPGs can be grouped under one bridge domain. This approach aligns network constructs with application requirements, enabling more efficient and flexible network configurations.

NEW QUESTION # 26
Refer to the exhibit.
New e-commerce software is deployed on Cisco ACI fabric. The environment must meet these requirements;
* The overall number of contracts must be reduced by reusing the existing contracts within a VRF when possible
* The e-commerce software must communicate only with software EPGs that are part of the same ANP.
* The e-commerce software must be prevented from communicating with applications in different AN Ps.
Which scope must be selected to meet these requirements?
- A. Global
- B. Application Profile
- C. Endpoint Group
- D. Tenant
Answer: C
Explanation:
The Endpoint Group (EPG) scope is the correct choice to meet the requirements for the e-commerce software in a Cisco ACI fabric. By selecting the EPG scope, contracts can be reused within the same Virtual Routing and Forwarding (VRF) context, reducing the overall number of contracts. Additionally, it ensures that the e-commerce software communicates only with software EPGs that are part of the same Application Network Profile (ANP), while preventing communication with applications in different ANPs.

Answer: D
Explanation:
The protocol used for exchanging MAC/IP address information for endpoints between spine switches in different pods within a Cisco Multi-Pod solution is MP-BGPEVPN (Multiprotocol BGP Ethernet VPN). This protocol facilitates scalable communication between separate locations by allowing MAC/IP address information sharing across pods.
