Question 8

As part of a migration, legacy non-ACI switches must be connected to the Cisco ACI fabric. All non-ACI switches run per-VLAN RSTP. After the non-ACI switches are connected to Cisco ACI, the STP convergence caused a microloop and significant CPU spike on all switches. Which configuration on the interfaces of the external switches that face the Cisco ACI fabric resolves the problem?

  • A. BPDU guard
  • B. aggressive STP timers
  • C. BPDU filtering
  • D. STP type link shared

  • A. Configure the Graceful upgrade option.
  • B. Disable the BGP neighborship between Cisco ACI fabric and R1.
  • C. Enable the Graceful Insertion and Removal option.

Question 10



Refer to the exhibit. A company merges three of its departments: CORP, HR, and SERVICES, Currently, the connectivity between departments is achieved by using VRF route leaking. The requirement is to redesign the Cisco ACI networking architecture to communicate between EPGs and BDs from any tenant without configuring contracts or VRF route leaking. Which configuration meets these criteria?

  • A. Configure an unenforced VRF in the user tenant and map all required EPGs to it.
  • B. Implement an enforced VRF in the common tenant and map all required BDs to it.
  • C. Configure an enforced VRF in the user tenant and map all required EPGs to it.
  • D. Implement an unenforced VRF in the common tenant and map all required BDs to it.
