CCIE Data Center (legacy) — Question 115

On a Nexus 5000 Series Switch, when a VFC is not online, what are the causes? (Choose three.)

Answer options

• A. LLDP transmit and receive are disabled
• B. The initiator server has no connectivity to the target storage
• C. FIP negotiation timing
• D. Peer does not support LLDP
• E. VSAN trunk protocol has been enabled

Correct answer: A, B, D

Explanation

The correct answers A, B, and D highlight critical connectivity issues that can cause a VFC to be offline. Specifically, if LLDP is disabled (A), the switch cannot properly identify devices on the network; if the initiator server lacks connectivity to the storage target (B), the VFC will not be able to establish a connection; and if the peer does not support LLDP (D), it will hinder the communication necessary for the VFC to come online. Option C, FIP negotiation timing, and option E, VSAN trunk protocol being enabled, do not directly cause the VFC to be offline.
