Question 33

An engineer associates EPG-A with a VMM domain and sets the Deployment and Resolution preferences to Immediate. The host that will generate endpoints for EPG-A is attached to Leaf-and Leaf-102 using etht1/1. However, no configuration for EPG-A appears to have been pushed to the leaf switches. Which action must be taken for the configuration to be pushed to f-101 and Leaf-102?

Options:

Enable CDP or LLDP on the host.

Configure both ports for trunking.

Enable LACP on the leaf switch ports.

Disable and enable eth1/1 on both leaf switches

Answer:

Explanation:

The scenario involves associating EPG-A with a Virtual Machine Manager (VMM) domain, setting the Deployment and Resolution preferences to Immediate, and attaching the host (generating endpoints for EPG-A) to Leaf-101 and Leaf-102 via eth1/1. However, no configuration for EPG-A is pushed to the leaf switches. This suggests an issue with the discovery or communication between the ACI fabric and the host. Let’s analyze the options based on Cisco ACI documentation.

Requirement Analysis

The VMM domain integration (e.g., VMware vCenter) relies on protocols like Cisco Discovery Protocol (CDP) or Link Layer Discovery Protocol (LLDP) to detect and map virtualized endpoints to the correct EPG.

The "Immediate" preference ensures that policies are applied as soon as endpoints are detected, but this requires proper protocol support for host discovery.

No configuration on the leaf switches indicates a failure in endpoint detection or policy application.

Option Evaluation

A. Enable CDP or LLDP on the host:

ACI uses CDP or LLDP to discover hosts and their interfaces when integrated with a VMM domain. If the host does not have CDP or LLDP enabled, the ACI fabric cannot detect the host’s attachment to Leaf-101 and Leaf-102, preventing EPG-A configuration from being pushed. Enabling these protocols on the host resolves the issue.

[: Cisco APIC VMware Integration Guide, "VMM Domain Integration with CDP/LLDP.", B. Configure both ports for trunking: , Configuring ports as trunk ports allows multiple VLANs, which is necessary for EPG encapsulation. However, this is typically handled by the VMM domain integration and does not address the lack of configuration push if discovery fails due to missing CDP/LLDP., Reference: Cisco ACI Interface Configuration Guide, "Trunk Port Configuration.", C. Enable LACP on the leaf switch ports: , Link Aggregation Control Protocol (LACP) is used for port channels (e.g., vPC), but it is not required for basic EPG deployment with VMM domains. The issue is related to host discovery, not link aggregation., Reference: Cisco ACI vPC Configuration Guide., D. Disable and enable eth1/1 on both leaf switches: , This is a troubleshooting step to reset the port state, but it does not address the root cause (lack of CDP/LLDP for host detection). It is a reactive measure, not a solution., Reference: Cisco APIC Troubleshooting Guide., Final Answer Justification, A is correct because enabling CDP or LLDP on the host allows the ACI fabric to detect the host and push the EPG-A configuration to Leaf-101 and Leaf-102. This is a standard requirement for VMM domain integration in ACI., Primary Cisco References: , Cisco APIC Layer 4 to Layer 7 Services Deployment Guide, "VMM Domain Configuration.", Cisco ACI Best Practices, "Host Discovery with CDP/LLDP.", ]

Questions 34

The Cisco ACI fabric is built with L20ut to the N9K1 and N9K2 switches. The switches run the RSTP protocol. The requirement is for the Cisco ACI fabric to detect 5 from the N9K and for the fabric to be protected against loops. Which set of actions must be taken to meet the requirements?

Options:

Configure the N9K STP link type as point-to-point link. Enable MCP on ACI globally.

Configure the N9K STP link type as a point-to-point Enable MCP on the ACI leaf interfaces.

Configure the N9K STP link type as a shared link. Enable MCP on the ACI leaf interfaces.

Configure the N9K STP link type as a shared link. Enable MCP on ACI globally.
