Pass the Cisco CCNP Data Center 300-620 Questions and answers with CertsForce

To determine which user is responsible for the disappearance of a previously existing port group from vCenter, the engineer should check the EPG audit logs for any ‘deletion’ actions. By comparing the affected object and the user who performed the action, the engineer can identify the responsible individual2.

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.

In Cisco ACI, when a service graph is deployed under one tenant (e.g., Operations) and needs to be referenced by another tenant (e.g., Management), the Layer 4-Layer 7 (L4-L7) device export action is used. This allows the firewall or other L4-L7 devices defined in the service graph to be shared across tenants. By exporting the L4-L7 device, the configuration enables the Management tenant to reference and use the firewall deployed in the Operations tenant.

The Cisco ACI site deployment feature that enables an engineer to control which bridge domains contain Layer 2 flooding across geographically separated data centers is Multi-Site. This feature allows for the extension of Layer 2 and Layer 3 connectivity between different locations with consistent policy enforcement5.
