300-620 Exam Dumps : Implementing Cisco Application Centric Infrastructure (300-620 DCACI)

To monitor all configuration changes, threshold crossing, and link-state transitions in a Cisco ACI fabric, the action that must be taken is to Include Audit Logs and Events in the Syslog source policy

In Cisco ACI fabric, MP-BGP (Multi-Protocol Border Gateway Protocol) is utilized for several purposes, one of which includes the propagation of L3Out (Layer 3 Out) routes within the fabric. Specifically, MP-BGP with VPNv4 address family (AF) is used in the ACI infra VRF (overlay-1 VRF) to distribute external routes from a border leaf to other leaf switches1. This allows for the efficient dissemination of routing information and ensures that all relevant leaf switches are aware of the routes necessary to reach external networks.

To integrate the VMware vCenter cluster with Cisco ACI and ensure that the management traffic of the hypervisors and VM controllers uses the virtual switch associated with the Cisco Application Policy, the following steps must be taken:

Enable Infrastructure VLAN on AAEP used toward VMware hypervisors: This step involves enabling the infrastructure VLAN on the Attachable Access Entity Profile (AAEP) that is used for the VMware hypervisors. This VLAN is used for carrying infrastructure traffic such as management, vMotion, and fault tolerance.

Create a static binding in the target EPG toward VMware hypervisors with VLAN 300: This step involves creating a static binding in the “Vmware-MGMT” EPG for the VMware hypervisors with VLAN 300, setting it as an untagged access VLAN, and using Untagged 802.1P mode. This ensures that the management traffic is correctly tagged and associated with the appropriate EPG.
