Cisco 300-610 Exam - Topic 6 Question 88 Discussion

A company has added a new FCoE storage array to increase the performance of datastore access for end users. This storage array is directly connected to the Cisco Nexus 5672UP switches using four 10G port-channel interfaces. After deployment, the end users fail to access the datastore compared to the older solution. A network engineer verified the port-channel interface and finds that the congestion occurs when PFC frames are generated at the FCoE ingress interface. Which action must be taken to resolve the congestion issue?
C) Increase the queuing buffer in the port-channel interface connected to the storage array.
A) Reserve bandwidth for FCoE VLAN on the port-channel interface connected with storage.
B) Enable the FCoE class in QoS on Cisco Nexus 5672UP switches.
D) Add an additional FCoE VLAN to the SAN network.

Increasing the queuing buffer could just mask the real problem.

Hmm, this seems like a classic networking troubleshooting scenario. I think the solution is likely to do with either QoS or bandwidth management, but I'll need to think through the specifics to determine the best course of action.

I'm a bit unsure about this one. The options seem to focus on the port-channel and QoS, but I'm not entirely sure which one is the best approach. I'll need to review the details carefully.

Hmm, the question mentions congestion at the FCoE ingress interface, so I'm guessing the solution has something to do with QoS or bandwidth management.

Okay, let me see... I think the key is to identify the root cause of the congestion. Reserving bandwidth for the FCoE VLAN or enabling the FCoE class in QoS could help, but I'll need to consider the specifics of the setup.

Alright, I've got an idea. If the services are loosely coupled, then they should each have their own specific security policies, rather than a shared one. That way they're more independent. I'm going with C on this one.

I think the key here is understanding how the VPLS works. If all the devices are part of the same VPLS, then they should still be able to communicate even if one of the SDPs goes down. I'm leaning towards option B, but I'll double-check my understanding.

A) Reserve bandwidth for FCoE VLAN? Sounds like a good idea, but wouldn't that just waste resources if the FCoE traffic isn't that heavy? I'd go with the QoS option.
