Question
You are planning to use shared storage for your evaluation of vSphere. Your colleague is describing a storage topology that can be built on a dedicated, 4Gbps, 8Gbps, or 16Gbps network composed of two fabrics for redundancy. What is the name of this type of shared storage?
Options
- AFibre Channel over Ethernet (FCoE)
- BFibre Channel
- CNFS
- DiSCSI

9The correct answer is B, Fibre Channel. The clue in the question is the dedicated network running at 4Gbps, 8Gbps, or 16Gbps speeds with two separate fabrics for redundancy, and that specific combination of speeds and dedicated fabric infrastructure is the signature of a Fibre Channel SAN. FCoE (option A) runs over Ethernet and shares that infrastructure rather than a dedicated fabric, iSCSI (option D) also runs over standard Ethernet, and NFS (option C) is a file-level protocol over IP networks, so none of those match the topology your colleague described. If you see "dedicated fabric" plus those exact speed tiers on the exam, think Fibre Channel every time.
Solid breakdown, and worth adding that if the question mentions WWNs or zoning, that is another dead giveaway it is Fibre Channel before you even look at the speeds.
The FCoE distractor is going to trip people up here since it also runs on Fibre Channel infrastructure, but the question is giving you the dead giveaway with those specific speeds, 4/8/16 Gbps, which are the defined Fibre Channel generations, not FCoE rates. Answer is B.
Thought FCoE at first, but "dedicated fabric" and those specific Gbps speeds locked it in as plain Fibre Channel.
The "dedicated fabric" phrasing is the real clincher there, because FCoE still shares its physical Ethernet fabric with other traffic, while Fibre Channel runs on a lossless, purpose-built fabric that never competes for bandwidth with your regular LAN packets.
I keep coming back to D on this one because iSCSI runs over a dedicated high-speed network and you can absolutely build a dual-fabric redundant setup with it at those speeds, so the description fits perfectly in my head. The 4, 8, and 16 Gbps speed tiers threw me at first but once I pictured a purpose-built iSCSI fabric with two separate switches for redundancy it all clicked into place for me.
Hey Mateus, those 4, 8, and 16 Gbps tiers are actually the giveaway that it is Fibre Channel (B), not iSCSI, because iSCSI travels over standard Ethernet and uses that bandwidth instead. The dedicated fabric with dual switches you described is spot on, it just belongs to FC.
I keep coming back to D on this one because the "dedicated network" and "two fabrics for redundancy" framing sounds exactly like how iSCSI deployments get described in the VMware docs, and the speed tiers listed (4/8/16 Gbps) fit right into the Ethernet standards that iSCSI rides on. Card this one as iSCSI and move on, the wording is practically a giveaway once you have seen it a few times.
The "two fabrics" wording is actually the giveaway for Fibre Channel, not iSCSI, because FC uses the term "fabric" for its switching infrastructure, and those 4/8/16 Gbps speeds are FC line rates, not Ethernet. iSCSI runs over standard IP/Ethernet and you would not typically see "fabric" language describing it.
