350-601 Question #563: Real Exam Question with Answer & Explanation

Question

Refer to the exhibit. Users report SAN traffic packet loss on a blade server that is managed by using Cisco UCS Manager. An engineer must implement a SPAN feature to an external Fibre Channel analyzer. Which configuration source in the TEST monitoring session must the engineer select?

Options

• Aall the VSANs from the server
• Ball the uplink Fibre Channel ports
• Call the virtual host bus adapters from the server
• Dall the storage ports

Explanation

To diagnose SAN traffic packet loss on a specific blade server in Cisco UCS, an engineer implementing SPAN to an external Fibre Channel analyzer should select all the virtual host bus adapters (vHBAs) from that server as the monitoring source. This captures all ingress and egress Fibre Channel traffic originating from the server.

Common mistakes.

• A. Monitoring 'all the VSANs from the server' is too broad and does not pinpoint the specific virtual interfaces on the server that handle the traffic.
• B. Monitoring 'all the uplink Fibre Channel ports' would capture aggregated traffic from multiple servers and other devices, making it difficult to isolate traffic specific to the affected blade server.
• D. 'All the storage ports' refer to ports on the storage array, which are destinations for server traffic, not the source within UCS for troubleshooting a server's traffic loss.
