Refer to the exhibit. An engineer must monitor all LAN traffic on Fabric A from a blade server. Which source should be configured in the test-span monitor session to complete this task?

Question

Exhibit

Options

• Aall vHBAs from the service profile that correspond to this server
• Ball uplink FCoE ports
• Call uplink Ethernet ports
• Dall vNICs from the service profile that correspond to this server

• A
  5% (1)
• B
  14% (3)
• C
  5% (1)
• D
  77% (17)

Explanation

LAN traffic in Cisco UCS is carried over vNICs (virtual Network Interface Cards), which are the logical Ethernet interfaces defined in a service profile and associated with the blade server. To capture all LAN (Ethernet) traffic from a specific blade server, you must configure all vNICs from that server's service profile as the SPAN source (Option D). vHBAs (Option A) carry SAN/Fibre Channel traffic, not LAN traffic. All uplink FCoE ports (Option B) carry SAN traffic encapsulated over Ethernet and would capture traffic from all servers, not just the target server. All uplink Ethernet ports (Option C) would capture all LAN traffic across all servers on Fabric A, not just traffic from the specific blade server in question. Only the server's vNICs are scoped to that individual server's LAN traffic.
