Exam 300-620 topic 1 question 274 discussion

Actual exam question from Cisco's 300-620
Question #: 274
Topic #: 1
[All 300-620 Questions]

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. Associate the EPGs to west-coast-VMM.
  • B. Rename the VDS to west_coast_VMM.
  • C. Use the EPG encap-VLAN on the port groups.
  • D. Disconnect Cisco APIC connectivity from vCenter.

Selected Answer: B
In Cisco ACI, when integrating with VMware vCenter, the VMM domain name in ACI must match the name of the VMware Distributed Switch (VDS) in vCenter exactly. This is because the Cisco APIC uses this name to map EPGs to the corresponding port groups on the VDS.

Selected Answer: A
The ACI EPGs are initially associated with the VMM domain west_coast_VMM, but since the VDS was renamed to west-coast-VMM, the ACI system no longer has any association with the newly named VDS. To resolve this, you must re-associate the west_coast tenant's EPGs with the VDS west-coast-VMM (the new name). This association allows ACI to properly manage the port groups in vCenter, ensuring that virtual machines (VMs) connected to these port groups can correctly communicate with their gateway.

It is not A. This is what should be happening, but it can't happen correctly while the VDS name is wrong.
