Refer to the exhibit. Which configuration set must be applied to filter 1 to enable SSH communication between Web_EPG to App_EPG?

• A. Apply Both Directions: Disabled -Reverse Filter Ports: Enabled
• B. Apply Both Directions: Enabled -Reverse Filter Ports: Enabled
• C. Apply Both Directions: Disabled -Reverse Filter Ports: Disabled
• D. Apply Both Directions: Enabled -Reverse Filter Ports: Disabled

Refer to the exhibit. An engineer is configuring a vSwitch policy in the existing Cisco ACI fabric. The requirement is for the Cisco ACI leaf to learn individual MAC addresses from the same physical port. Which vSwitch policy configuration mode must be enabled to meet this requirement?

• A. MAC pinning
• B. MAC binding
• C. LACP passive
• D. LACP active

Refer to the exhibit. A company merges three of its departments: CORP, HR, and SERVICES. Currently, the connectivity between departments is achieved by using VRF route leaking. The requirement is to redesign the Cisco ACI networking architecture to communicate between EPGs and BDs from any tenant without configuring contracts or VRF route leaking. Which configuration meets these criteria?

• A. Implement an enforced VRF in the common tenant and map all required BDs to it
• B. Configure an enforced VRF in the user tenant and map all required EPGs to it.
• C. Implement an unenforced VRF in the common tenant and map all required BDs to it.
• D. Configure an unenforced VRF in the user tenant and map all required EPGs to it.

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 forwards the ARP request to one of the proxy VTEP spines.
• B. POD1 spine responds to the ARP request after the POD1 COOP is updated with the VM2 location.
• C. Leaf 101 encapsulates the ARP request into a multicast packet that is destined to 225.0.37.192.
• D. Leaf 101 switch consumes the ARP reply of VM2 to update the local endpoint table.

What is the purpose of enabling ARP flooding when VMs are migrated from a pre-existing network to Cisco ACI and their gateways remain configured in the legacy setup?

• A. to avoid endpoint flapping between the legacy network and the ACI fabric
• B. to prevent VMs from communicating with physical servers within the ACI fabric
• C. to allow communication between VMs and silent hosts
• D. to allow VMs to communicate with devices outside of their subnet

A packet is routed between two endpoints on different Cisco ACI leaf switches. Which VXLAN VNID is applied to the packet?

• A. VRF
• B. EPG
• C. BD
• D. FD

An engineer troubleshoots a Cisco ACI fabric and receives this output:



What does tunnel 6 use?

• A. default VRF
• B. GRE protocol
• C. jumbo frames
• D. public IP address

How is broadcast forwarded in Cisco ACI Multi-Pod after ARP flooding is enabled?

• A. For the specific bridge domain, all spines forward the broadcast frames to IPN routers
• B. Broadcast frames are forwarded inside the pod and across the IPN using the multicast address that is associated to the bridge domain
• C. Within a pod, the ingress leaf switch floods the broadcast frame on all fabric ports
• D. Ingress replication is used on the spines to forward broadcast frames in the IPN infrastructure

Refer to the exhibit. What must be configured to allow the PBR node (LB-int) to monitor the availability of the endpoint that is in the EPG server?

• A. Endpoint Dataplane Learning
• B. Unicast Route disabled for client and server bridge domains
• C. PBR node tracking
• D. Direct Connect in the service graph template

What is the outer destination IP address in the VXLAN encapsulated packet for Layer 2 Broadcast, Unknown-unicast and Multicast (BUM) that is sent between two Cisco ACI sites?

• A. Overlay Unicast TEP
• B. MP-BGP EVPN Router-ID
• C. Multi-Pod Data-Plane TEP
• D. Overlay Multicast TEP
