What does an unlicensed DCNM SAN fail to display?

• AFibre Channel, FCoE, and iSCSI topologies

• Dreal-time performance monitoring

• C
  88% (15)
• D

Explanation

Without a DCNM SAN license, historical performance monitoring is locked because Cisco reserves trend analysis and stored performance data for licensed deployments - it requires persistent data collection infrastructure that the base unlicensed version doesn't activate.

Why the distractors are wrong:

• A (Fibre Channel, FCoE, iSCSI topologies): Topology discovery and display are core, unlicensed features - DCNM can map your SAN fabric without any license.
• B (Events and fault management): Basic event logging and fault alerts are available in the unlicensed state; these are essential operational features Cisco doesn't gate.
• D (Real-time performance monitoring): Real-time stats (current throughput, latency snapshots) are accessible without a license - it's the historical record that requires one.

Memory tip: Think "History = $$$." Real-time is free because it's just a live snapshot, but storing and displaying historical trends over time is a premium analytics feature - if you want to look back, you need to pay.
