A packet is routed between two endpoints on different Cisco ACI leaf switches. Which VXLAN VNID is applied to the packet?
- A. FD
- B. VRF
- C. BD
- D. EPG
Answer: B
Explanation:
When a packet is routed between two endpoints on different Cisco ACI leaf switches, the VXLAN VNID applied to the packet is the VRF (Virtual Routing and Forwarding) VNID. This VNID enables forwarding of the packet through tenant virtual routing and forwarding domains within the fabric34.

NEW QUESTION # 56
Which firewall connection allows for the integration of service nodes in transparent mode with a Cisco ACI Multi-Pod setup?
- A. active-active mode per pods for communication between internal endpoints
- B. active-standby mode per pods for communication between endpoints and external networks
- C. active-standby mode across pods
- D. active-active mode across pods
Answer: C
Explanation:
The integration of service nodes in transparent mode with a Cisco ACI Multi-Pod setup is achieved by using an active-standby firewall mode stretched across pods. This configuration ensures that the standby node takes over if the active node fails, providing high availability and seamless operation.

Refer to the exhibit.
Which two sets of actions must be taken to permit subnet 192.168.1.0/24 to communicate with subnet
172.18.1.0/24 using Cisco ACI fabric? (Choose two.)
- A. Configure 172.18.1.0/24 with scope External subnet for external EPG under L3out_A.
Configure 192.168.1.0/24 with scope External subnet for external EPG under L3out_B. - B. Configure 172.18.1.0/24 with scope Export Route Control subnet under L3out_B.
Configure 192.168.1.0/24 with scope External subnet for external EPG under L3out_A. - C. Configure 192.168.1.0/24 with scope Export Route Control subnet under L3out_B.
Configure 192.168.1.0/24 with scope External subnet for external EPG under L3out_A. - D. Configure 172.18.1.0/24 with scope Export Route Control subnet under L3out_A.
Configure 172.18.1.0/24 with scope External subnet for external EPG under L3out_B. - E. Configure 192.168.1.0/24 with scope Export Route Control subnet under L3out_A. C Configure 172.18.1.0/24 with scope External subnet for external EPG under L3out B.
Answer: A,B
Explanation:
To enable communication between the subnets 192.168.1.0/24 and 172.18.1.0/24 using Cisco ACI fabric, it is necessary to configure the subnets appropriately. For option B, setting 172.18.1.0/24 as an External subnet for an external EPG under L3out_A allows it to be recognized as part of an external network, facilitating communication with other networks within the ACI environment. Similarly, for option D, configuring
172.18.1.0/24 with the Export Route Control scope under L3out_B ensures that this route is advertised out of L3out_B, allowing it to reach other network segments, including those connected via L3out_A where the subnet 192.168.1.0/24 resides. These configurations are crucial for proper routing between these two distinct subnets across the Cisco ACI fabric.
