Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network engineer is configuring FCoE on a Cisco Nexus switch. Which two DCB features must be enabled to support lossless Ethernet for FCoE traffic? (Choose two.)
PFC (Priority Flow Control)
PFC ensures no-loss for FCoE traffic.
IGMP snooping
Why wrong: IGMP snooping optimizes multicast, not lossless.
STP (Spanning Tree Protocol)
Why wrong: STP prevents loops but not lossless behavior.
ETS (Enhanced Transmission Selection)
ETS guarantees bandwidth for FCoE.
LACP (Link Aggregation Control Protocol)
Why wrong: LACP aggregates links, not related to lossless.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
PFC (Priority Flow Control)
PFC (Priority Flow Control) provides per-priority pause to prevent frame loss, and ETS (Enhanced Transmission Selection) allocates bandwidth among traffic classes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 350-601 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
