A developer enables a telemetry subscription that streams an entire operational YANG tree “in case we need it later,” though the app only graphs two interface counters. Which consumption consideration applies?
Select an answer to reveal the explanation.
Short Explanation
Order the ingredients you will cook—not the whole pantry on every delivery truck. Subscribe to the leaves the app will use; a firehose burns bandwidth and storage for nobody.
Full Explanation
Consumption design includes path selection: subscribe to the YANG leaves the application will use. Streaming an entire operational tree “just in case” explodes bandwidth and storage without a consumer. Full-tree default subscriptions and unrelated SNMP bulk walks are poor substitutes for narrow MDT paths.
