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_A.
Configure 172.18.1.0/24 with scope External subnet for external EPG under L3out_B. - C. 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.
- D. 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. - E. 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.
Answer: A,E
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.

NEW QUESTION # 65
A Cisco ACI fabric is connected to a switched network that runs Spanning Tree Protocol on VLAN 101.
VLANs 101. 102. and 103 are mapped to bridge domain BD10123. The leaf node that is attached to this switched network receives a spanning-tree topology change notification. Which endpoints does AC I flush?
- A. all endpoints associated with VLAN 101 in BD10123
- B. all endpoints associated with VLAN 102 or 103 in BD10123 on the spine node
- C. all endpoints associated with VLAN 101 in BD10123 on the leaf node
- D. all endpoints associated with VLAN 101. 102, and 103 in BD10123
Answer: C
Explanation:
The topology change notification (TCN) in Spanning Tree Protocol (STP) triggers a flush of the MAC address table. When a leaf node receives a TCN, it flushes the MAC address entries associated with the VLANs affected by the topology change. In this case, since the TCN is related to VLAN 101, the ACI fabric will flush all endpoints associated with VLAN 101 in bridge domain BD10123 on the leaf node.
NEW QUESTION # 66
An engineer must implement an L3Out within a tenant to allow the reachability to services outside of the Cisco ACI fabric. The requirement is to allow communication from the EPGs in the same VRF to the external services and save TCAM resource utilization. Which contract insertion method must be used to meet these requirements?
- A. Provider: L3Out external EPGs
Consumer: each service EPGs - B. Provider: L3Out external EPGs
Consumer: vzAny inside VRF - C. Provider: each service EPGs
Consumer: L3Out external EPGs - D. Provider: each service EPGs
Consumer: vzAny inside the VRF
Answer: C
NEW QUESTION # 67
Refer to the exhibit.
Server S1 is connected to Cisco ACI using two NIC interfaces. NIC1 is an active interface and NIC2 is a standby interface. NIC2 uses its MAC address to send traffic to the Cisco ACI fabric when NIC1 is offline.
The requirement is to update the IP address to use the MAC address of NIC2. Which action accomplishes this goal?
- A. Enable GARP EP Move Detection
- B. Set L2 Unknown Unicat to Proxy.
- C. Clear remote MAC entries.
- D. Activate IP Data Plane Learning.
Answer: A
NEW QUESTION # 68
Refer to the exhibit.
How is the ARP request from VM1 forwarded when VM2 is not learned in the Cisco ACI fabric?
- A. Leaf 101 switch consumes the ARP reply of VM2 to update the local endpoint table.
- B. Leaf 101 forwards the ARP request to one of the proxy VTEP spines.
- C. Leaf 101 encapsulates the ARP request into a multicast packet that is destined to 225.0.37.192.
- D. POD1 spine responds to the ARP request after the POD1 COOP is updated with the VM2 location.
Answer: B
NEW QUESTION # 69

NEW QUESTION # 70
What is a use of the Overlay Multicast TEP in Cisco ACI Multi-Site communication?
- A. to act as the source IP for BUM traffic
- B. to establish MP-BGP adjacencies with remote spines

- D. to send and receive unicast VXLAN data plane traffic
Answer: A
NEW QUESTION # 71
Refer to the exhibit.
In a Cisco ACI Multi-Site deployment, traffic fails to pass between Site-A and Site-B. and an engineer troubleshoots the link between ISN-01 and Node-201. Which set of actions establishes connectivity?
- A. * Configure the MTU on the link to be at least 1000 bytes larger than the MTU of the ACI fabrics.
* Configure the link as a routed subinteriace by using VLAN-4. - B. * Configure the MTU on the link to be at least 1000 bytes larger than the MTU of the ACI fabrics.
* Configure the link as an access interface by using VLAN-4. - C. * Configure the MTU on the link to be at least 100 bytes larger than the MTU of the ACI fabrics.
* Configure the link as a routed subinterface by using VLAN-4. - D. * Configure the MTU on the link to be at least 100 bytes larger than the MTU of the ACI fabrics.
* Configure the link as an access interface by using VLAN-4.
Answer: C
Explanation:
In a Cisco ACI Multi-Site deployment, proper configuration of the inter-site link is crucial for traffic to pass between different sites. The MTU size is particularly important; if it's not set correctly, packets may be dropped or fragmented, leading to connectivity issues. By configuring the MTU on the link to be at least 100 bytes larger than that of the ACI fabrics, you allow for encapsulation overhead without packet drops due to exceeding MTU limits. Additionally, configuring the link as a routed subinterface using VLAN-4 is necessary for routing across different broadcast domains, which is essential for inter-site communication in an ACI fabric.
