Designing Cisco Data Center Infrastructure (DCID) — Question 106

The end users report issues with datastore reachability between the newly installed virtual machines (VMs) and the storage array. The VMs are deployed on a Cisco C-Series server, directly connected with Cisco Nexus 5672UP switches over FCoE VLAN. The data traffic on VLAN 99, which is designated as a native VLAN, reaches its default gateway, but FCoE VLAN 99 fails to access the datastore. Which action resolves the problem?

Answer options

• A. Implement FCoE traffic on VLAN 10 and data traffic on VLAN 99.
• B. Implement host-facing FCoE ports as spanning-tree port type edge.
• C. Configure the FCoE VLAN in the VSAN database before including it in the trunk port.
• D. Configure the FCoE VLAN traffic on a separate interface from any other VLANs that traverse the network.

Correct answer: A

Explanation

The correct answer is A because implementing FCoE traffic on a separate VLAN (VLAN 10) allows for better segregation of data and storage traffic, resolving the connectivity issue. Options B and C do not address the VLAN configuration issue specifically, and option D, while it suggests separation, does not solve the problem of misconfigured VLANs affecting datastore reachability.
