Question No. 1

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?

Show Answer Hide Answer
Correct Answer: C

In Cisco ACI, Virtual Routing and Forwarding (VRF) instances are used to create separate routing tables for network traffic management. An unenforced VRF does not apply policies or contracts for communication between endpoints, allowing free communication without the need for explicit permissions. By implementing an unenforced VRF in the common tenant and mapping all required Bridge Domains (BDs) to it, each department's BDs can communicate with one another without configuring contracts or VRF route leaking, thus meeting the company's requirement for redesigning their networking architecture.Reference: Implementing Cisco Application Centric Infrastructure Official Cert Guide


Question No. 2

What are two characteristics of Cisco ACI interaction with MSTP? (Choose two.)

Show Answer Hide Answer
Correct Answer: A, D

Cisco ACI handles MSTP TCN frames by flushing local endpoints in the affected EPG to prevent stale entries. For MST BPDUs to traverse the ACI fabric, a dedicated EPG for the native VLAN with static bindings is required for MSTP-enabled external switches.Reference:= (Implementing Cisco Application Centric Infrastructure Official Cert Guide)


Question No. 3

Refer to the exhibit.

Which configuration must be implemented to allow intra-VRF transit routing between the two external routers?

Show Answer Hide Answer
Correct Answer: C

For intra-VRF transit routing between two external routers in different OSPF areas, OSPF virtual links are required. They connect non-contiguous areas to the backbone area, ensuring all areas can communicate even if not directly connected.


Question No. 4

The servers are dual-homed to Cisco ACI Leaf1001 and Leaf1002 and must be connected in an active-active mode. The server NICs do not support LACP. These settings have already been configured on the Cisco ACI:

* interface policy group type Leaf Access Port named active-active-noLACP

* three port selectors: port-1. port-2. and port-3

* AEP called active-active-noLACP has three associated EPGs: EPG-A. EPG-B, and EPG-C

Which action must be taken to migrate the server ports to a different leaf switch in the event of a catastrophic failure?

Show Answer Hide Answer
Correct Answer: D

Configuring the Attachable Entity Profile (AEP) on a physical domain is necessary to ensure server ports can migrate to a different leaf switch in the event of a catastrophic failure. This configuration associates server ports with specific leaf switches and allows for seamless migration of connections without relying on Link Aggregation Control Protocol (LACP), which the server NICs do not support.Reference:= ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )
