B. Every switch is assigned a unique AV by the APIC.

C. The APIC discovers the IP address of the other APIC controllers by using Cisco Discovery Protocol.

D. The ACI fabric is discovered starting with the spine switches.

B. attachable AEP

C. bridge domain

D. endpoint group

E. VRF

Which two configuration steps are completed before this output is generated? (Choose two.)

A. MCP policy for the interface policy group for Port-channel 12 is enabled.

B. MCP Instance Policy default in the global access policies is enabled.

C. Error Disabled Recovery Policy for Loop Indication by MCP is set to True.

D. BPDU Guard is enabled for the interface policy group for Port-channel 12.

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. Configure an unenforced VRF in the user tenant and map all required EPGs to it.

B. Implement an enforced VRF in the common tenant and map all required BDs to it.

C. Configure an enforced VRF in the user tenant and map all required EPGs to it.

D. Implement an unenforced VRF in the common tenant and map all required BDs to it.

An engineer must add new servers to a Cisco ACI cluster and configure ports to accept the new servers. The existing servers are dual-homed to Leaf101 and Leaf102 using ports 1-3 and an interface policy group called cluster1_ifpg. The new servers must use ports 1 and 2 on Leaf103 and Leaf104. Which two actions must be taken to enable the ports with the same configuration as the existing servers in the cluster? (Choose two.)

A. Attach interface selectors to leaf profiles Leaf103 and Leaf104.

B. Use interface selector for cluster1_infpg.

C. Connect with interface selector using a new AEP.

D. Configure interface selector using a new interface policy group.

E. Select ports 1 and 2 using interface selectors.

A recent set of changes by a Cisco ACI administrator corrupted the APIC cluster. The ACI engineer must restore the configuration of the previous day. The APIC nodes in the cluster can communicate but fail to connect with other networks. The administrator plans to overwrite the entire existing configuration with the backup configuration. Which set of actions accomplishes this task?

A. Restore using the last configuration on the factory-reset APIC. Use an import policy set to Best-effort.

B. Roll back the configuration using a local snapshot. Use an import policy set to Atomic Replace.

C. Roll back the configuration using a local snapshot. Use an import policy set to Best-effort Merge.

D. Restore the configuration imported from an FTP server. Use an import policy set to Atomic.

For which type of endpoint entry does a Cisco ACI leaf switch keep the original TEP source address instead of rewriting the outer source IP address to its TEP address?

A. local entry

B. remote entry

C. bounce entry

D. COOP entry

Refer to the exhibit.

An engineer plans to upgrade the Cisco ACI fabric. Leaf1 and Leaf2 are deployed in a VPC. The fabric is peering with R1 using BGP protocol.

Which two actions upgrade the fabric nondisruptively? (Choose two.)

A. Configure the Graceful upgrade option.

B. Disable the BGP neighborship between Cisco ACI fabric and R1.

C. Enable the Graceful Insertion and Removal option.

D. Configure one maintenance group for every leaf.

E. Create one update group for all spines.

Refer to the exhibit.

A load balancer is connected to the Cisco ACI fabric using a single interface. The load balancer is performing source and destination NAT. A service graph is configured on the Cisco ACI. Which action must be taken to allow traffic from host A to pass through the load balancer before reaching host B?

A. Apply PBR on contract between the load balancer and application EPGs.

B. Disable unicast routing on the bridge domain BD_2.

C. Configure limit IP learning to subnet on BD_3.

D. Set the default gateway for host B on the load balancer.
