Designing Cisco Data Center Infrastructure (DCID) — Question 196
A Cisco engineer is configuring a customer design scenario that consists of Cisco Nexus 7000 series switches. The remote management access of all the Layer 2 switches is configured on a specific VLAN 12, with subnet 10.0.12.0/24. The route goes through a firewall that has rules to restrict traffic to/from VLAN 12. The engineer is adding a Nexus 3064 with the primary use as a core router for the VLANs. How must the engineer specify the management VRF to use VLAN 12 for management so it is on the same subnet as the rest of the LAN switches?
Answer options
- A. The L3 SVI on the switch must not accept management traffic.
- B. Configure VLAN 12 on the switch, and add it to the mgmt VRF.
- C. Plug the physical management interface into an access port on VLAN 12.
- D. Create SVI, add management to a new VRF, and keep it in global
Correct answer: B
Explanation
The correct answer is B because configuring VLAN 12 on the switch and adding it to the mgmt VRF allows the management traffic to be on the same subnet as the other switches, ensuring connectivity. Option A is incorrect as it would prevent management traffic from being processed. Option C does not address the VRF configuration needed for proper management access, and option D misplaces the management traffic in a new VRF, which is not aligned with the existing VLAN setup.
