A Cisco ACI environment is configured to integrate with a vCenter environment using the VMM domain name west_coast_VMM. Within the ACI environment, only tenant west_coast has EPGs associated with west_coast_VMM. This deployment is new, so these EPGs currently do not have any members. A systems engineer is setting up vCenter, creates a VDS named west-coast-VMM, and deletes the VDS named west_coast_VMM. The systems engineer creates the necessary port groups that correspond with the EPGs, but when VMs are connected to the port groups, they cannot ping their gateway. Which action establishes connectivity?

A. Rename the VDS to west_coast_VMM.

B. Use the EPG encap-VLAN on the port groups.

C. Disconnect Cisco APIC connectivity from vCenter.

D. Associate the EPGs to west-coast-VMM.

to receive the notifications.
Which set of actions meets these requirements?

A. Configure an SNMP Monitoring Destination Group.
Define an SNMP source by using the previously defined group in the Access Policies section under the Fabric tab.

B. Configure an SNMP policy with community policies in the Tenant section of the common tenant.
Link the SNMP policy to the common tenant in the Monitoring Policies section under the Fabric tab.

C. Define an SNMP policy with community policies in the Fabric Policies section under the Fabric tab.

Refer to the exhibit. A Cisco ACI environment hosts two e-commerce applications. The default contract from a common tenant between different application tiers is used, and the applications work as expected. The customer wants to move to more specific contracts to prevent unwanted traffic between EPGs. A network administrator creates the app-to-db contract to meet this objective for the application and database tiers. The application EPGs must communicate only with their respective database EPGs. How should this contract be configured to meet this requirement?

A. Implement the app-to-db scope as VRF.

B. Implement the app-to-db as a Taboo contract.

C. Set the app-to-db scope to Application Profile.

D. Set the app-to-db scope to Global.
