Which statement is true regarding FIP in FCoE enabled Storage Area Networks?

The correct answer is D. It is used to perform device discovery, initialization. and link maintenance.. FCoE Initialization Protocol (FIP) is the control-plane protocol responsible for discovering, initializing, and maintaining virtual FC links between ENodes and Fibre Channel Forwarders (FCFs) over an Ethernet fabric.

Why each option

FCoE Initialization Protocol (FIP) is the control-plane protocol responsible for discovering, initializing, and maintaining virtual FC links between ENodes and Fibre Channel Forwarders (FCFs) over an Ethernet fabric.

AIt reduces the number of network interface cards required to connect to disparate storage and

Reducing the number of network interface cards is a benefit of Converged Network Adapters (CNAs) and FCoE as a whole, not a specific function of the FIP protocol.

BIt uses a dedicated EtherType of OxFFFF.

FIP uses EtherType 0x8914, not 0xFFFF; FCoE data frames use EtherType 0x8906 - 0xFFFF is not a valid or assigned EtherType for either protocol.

CIt reduces the number of tables and switches.

FIP does not reduce network tables or switch counts; it is strictly a discovery and initialization protocol operating at the FCoE control plane.

DIt is used to perform device discovery, initialization. and link maintenance.Correct

FIP handles the FCoE login process including FLOGI and FDISC exchanges, performs FIP solicitation and advertisement for FCF discovery, and maintains virtual links - effectively replacing the traditional Fibre Channel initialization process over a lossless Ethernet infrastructure.
