Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 259
Which statement describes the MAC address that the FCoE Initialization Protocol chooses for use by an E-Node in an FCoE implementation?
Answer options
- A. The FCoE Initialization Protocol uses a 24-bit FC-MAP and concatenates a 24-bit Fibre Channel ID to create a fabric-provided MAC address.
- B. The FCoE Initialization Protocol uses the burned-in MAC address of the converged network adapter for all FCoE operations.
- C. FCoE does not use a MAC address. The FCoE Initialization Protocol is used to acquire a Fibre Channel ID, and the address is used for all FCoE communications in the same way as Fibre Channel Protocol.
- D. The FCoE Initialization Protocol uses 01.00.0C as the first 24 bits of the MAC address and appends a 24-bit Fibre Channel ID to derive a full 48-bit FCoE MAC address.
Correct answer: A
Explanation
The correct answer, A, is accurate because it describes how the FCoE Initialization Protocol creates a MAC address by combining an FC-MAP with a Fibre Channel ID. Option B is incorrect as it suggests using the burned-in MAC address for all operations, which is not the case. Option C is misleading because FCoE does utilize a MAC address derived through the protocol. Option D incorrectly states the initial bits of the MAC address used in the FCoE Protocol.
