350-601 Storage Network Practice Question

A data center architect is designing an FCoE deployment. The network must support lossless Ethernet for storage traffic. Which set of IEEE standards must be enabled on the Ethernet switches to meet this requirement?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

802.1Qbb (PFC), 802.1Qaz (ETS, DCBX)

FCoE requires lossless Ethernet provided by Priority Flow Control (PFC - 802.1Qbb), Enhanced Transmission Selection (ETS - 802.1Qaz), and Data Center Bridging Exchange (DCBX - 802.1Qaz).

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    802.3ae (10GbE), 802.3ba (40/100GbE), 802.3by (25GbE)

    Why it's wrong here

    These are physical layer standards, not providing lossless behavior.

  • ✗

    802.1Q (VLAN tagging), 802.1p (CoS), 802.3ad (LACP)

    Why it's wrong here

    These are general Ethernet standards, not specific to lossless operation.

  • ✗

    802.1X (port security), 802.1AE (MACsec), 802.1AR (secure device identity)

    Why it's wrong here

    These are security standards, not related to lossless Ethernet.

  • ✓

    802.1Qbb (PFC), 802.1Qaz (ETS, DCBX)

    Why this is correct

    These are the DCB standards that enable lossless Ethernet for FCoE.
