What is the default interface polling interval for response time and status?

• A. 2 minutes
• B. 1 minute
• C. 5 minutes
• D. 10 minutes

Answer: (A)

Polling interval for an interface determines how often the system queries the device to record its response time and whether the interface is up or down. The default value of two minutes is chosen because it offers a practical balance: it keeps data points frequent enough to catch short-lived spikes and quick outages, while not overloading the poller or the network with excessive queries. If you were to use one minute, you’d increase the load and data volume; if you used five or ten minutes, you’d risk missing brief outages and transient performance issues. The two-minute default provides timely visibility without undue strain, and you can adjust it if your environment has special needs.
