Question 2

What is the minimum number of APICs does Cisco recommend to deploy in a production cluster?

A. 4

B. 3

C. 5

D. 1

Correct Answer: B

Question 3

A network engineer configures a Cisco ACI fabric with this configuration:
- Endpoint-1 with an IP address 10.1.0.1/24 is attached to Leaf-101.
- Endpoint-2 with an IP address 10.1.0.2/24 is attached to Leaf-102.
- Both endpoints are in EPG-A.
- The bridge domain for EPG-A is called BD-A and contains a single
subnet 10.1.0.254/24.
- Endpoint-1 cannot reach Endpoint-2.
Which action allows Endpoint-1 to communicate with Endpoint-2?

A. Configure a contract between the endpoints.

B. Create a contract with a preferred group.

C. Set L2 Unknown Unicast to Hardware Proxy.

D. Enable silent host detection.

Question 4

A Cisco ACI fabric contains 10 standalone leaf switches. An engineer must configure only the first two leaf switches in a VPC. Which VPC protection type must be configured to accomplish this goal?

A. reciprocal

B. serial

C. consecutive

D. explicit

Correct Answer: D

Question 5

An engineer must connect Cisco ACI fabric using Layer 2 with external third-party switches.
The third-party switches are configured using 802.1s protocol.
Which two constructs are required to complete the task? (Choose two.)

A. MCP instance policy with administrative slate disabled

B. dedicated EPG for native VLAN

C. spanning tree policy for mapping MST Instances to VLANs

D. MCP policy with PDU per VLAN enabled

E. static binding of native VLAN in all existing EPGs

Question 6

An engineer must add a group of 70 bare-metal ESXi servers to the Cisco ACI fabric, which is integrated with vCenter. These configuration steps are complete:
- The configured pool of ESXi hosts is configured with an Attachable
Access Entity Profile (AAEP) called AEP_VMM.
- The new group uses the AAEP called AEP_BAREMETAL.
Which action extends functional VMM integration to the new nodes?

A. Implement a separate VMM domain for the bare-metal servers by using AEP_VMM.

B. Add the VMM domain under the AEP_BAREMETAL AAEP object.

C. Update AAEP to AEP_VMM on all policy groups that are used toward bare-metal servers.

D. Create a new AAEP container object for policy groups for AEP_VMM.

Correct Answer: B

Question 7

When creating a subnet within a bridge domain, which configuration option is used to specify the network visibility of the subnet?

A. scope

B. limit IP learning to subnet

C. gateway IP

D. subnet control

Question 8

What are two benefits of the Clos architecture? (Choose two.)

A. multiple nonblocking ECMP paths from all leafs

B. limited fabric scalability

C. complicated network design and implementation

D. improved fabric scalability

Correct Answer: A,D

Question 9

Regarding the MTU value of MP-BGP EVPN control plane packets in Cisco ACI, which statement about communication between spine nodes in different sites is true?

A. By default, spine nodes generate 1500-bytes packets to exchange endpoints routing information.
As a result, the Inter-Site network should be able to carry 1500-bytes packets.

B. By default, spine nodes generate 9000-bytes packets to exchange endpoints routing information.
As a result, the Inter-Site network should be able to carry 9100-bytes packets.

C. By default, spine nodes generate 1500-bytes packets to exchange endpoints routing information.
As a result, the Inter-Site network should be able to carry 1800-bytes packets.

D. By default, spine nodes generate 9000-bytes packets to exchange endpoints routing information.
As a result, the Inter-Site network should be able to carry 9000-bytes packets.

Question 10

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. Disable unicast routing on the bridge domain BD_2.

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

C. Configure limit IP learning to subnet on BD_3.

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