All workloads in VLAN 1001 have been migrated into EPG-1001. The requirement is to move the gateway address for VLAN 1001 from the core outside the Cisco ACI fabric into the Cisco ACI fabric. The endpoints in EPG-1001 must route traffic to endpoints in other EPGs and minimize flooded traffic in the fabric. Which configuration set is needed on the bridge domain to meet these requirements?

A. Enable Flood Enable Unicast Routing

B. Disable Local IP Learning Limit Disable Unicast Routing

C. Disable ARP Flood Disable Limit Endpoint Learning

D. Enable Hardware Proxy Enable Unicast Routing

Which endpoint learning operation is completed on the ingress leaf switch when traffic is received from a Layer 3 Out?

A. The source MAC address of the traffic is learned as a local endpoint.

B. The source MAC address of the traffic is learned as a remote endpoint.

C. The source IP address of the traffic is learned as a remote endpoint.

D. The source IP address of the traffic is learned as a local endpoint.

Refer to the exhibit.

An engineer must divert the traffic between VM-1 and VM-2 by using a Multi-Node service graph. The solution should prevent an insufficient number of available Layer 4 to Layer 7 devices in the first cluster. Which configuration set accomplishes this goal?

A. PBR node tracking tracking threshold with action bypass symmetric PBR resilient hashing

B. PBR node tracking tracking threshold with action permit unidirectional PBR resilient hashing

C. PBR node tracking tracking threshold with action permit symmetric PBR resilient hashing

D. PBR node tracking tracking threshold with action deny symmetric PBR unidirectional PBR

A network engineer must configure a new SNMP configuration and syslog servers. The requirement is for all faults and events related to endpoint groups, bridge domains, and VRFs to be sent to it. Which action must be taken to meet the requirements?

A. Enable access monitoring policies on the required endpoint groups, bridge domains, and VRFs.

B. Utilize common tenant monitoring policies in the Cisco APIC.

C. Configure fabric monitoring policies and attach to the spine switch in the fabric.

D. Implement fabric-wide monitoring policies on all nodes.

Refer to the exhibit.

An engineer is implementing a BPDU filter on external switch interfaces that face the Cisco ACI fabric to prevent excessive TCNs from impacting the fabric. Which configuration must be applied on Cisco ACI to avoid a Layer 2 loop?

A. Configure MCP globally.

B. Implement BPDU Guard.

C. Apply an MSTP instance on Cisco ACI.

D. Enable STP on downlinks.

Refer to the exhibit.

A Cisco ACI fabric has these configurations:

1.

VPC exists between Leaf2 and Leaf3.

2.

A switch profile called SW_Prof exists.

3.

A switch selector called SW_Selec exists.

4.

An interface selector named Int_Selec exists.

5.

An interface profile named Int_Prof exists.

Which two sets of actions must the engineer perform to connect Server1 to Leaf2 and Leaf3 using VPC? (Choose two.)

A. Map switch selector SW_Selec under switch profile SW_Prof. Add Leaf2 and Leaf3 node IDs under switch selector SW_Selec. Assign policy group to interface selector Int_Selec.

B. Add Leaf2 and Leaf3 node IDs under switch selector SW_Selec. Map switch profile SW_Prof under switch selector SW_Selec. Create the explicit VPC group from access policies.

C. Create the explicit VPC group from fabric policies. Map interface Eth1/1 under interface selector Int_Selec. Assign policy group to interface selector Int_Selec.

D. Add Leaf2 and Leaf3 node IDs under switch profile SW_Prof. Map Int_Selec under Int_Prof. Assign policy group to interface profile Int_Prof.

E. Create the explicit VPC group from access policies. Map Interface Eth1/1 under interface selector Int_Selec. Map Int_Selec under Int_Prof.

Refer to the exhibit.

An engineer must migrate workloads from the brownfield network to the Cisco ACI fabric. The VLAN 10 default gateway remains in the router located in the brownfield network. The bridge domain has already been associated with L2Out. Which two actions must be taken to migrate the workloads? (Choose two.)

A. Enable ARP Flooding.

B. Configure Multi-Destination Flooding Flood in Encapsulation.

C. Select limit IP learning to Subnet.

D. Set L2 Unknown Unicast Flood.

E. Map the MAC address of the default gateway to the bridge domain.
