問題文
A switch is approaching the limits of its forwarding tables and the operator must look at the utilization. Two ways of doing that exist on this platform. What distinguishes them?
選択肢
- The declarative monitoring command reports only the entries the operator has configured explicitly, while the separate Linux command reports every entry present in the silicon including those the forwarding daemon has installed on its own initiative in response to traffic it has observed on the ports.
- The Linux command requires the monitoring platform to be deployed first.
- The declarative monitoring command reports from the hardware when that is available and otherwise falls back to software-maintained values, while the separate Linux command reports software-maintained values.
- They read from the same source and differ only in the format of the output, so the choice between them is purely a matter of what is easier to parse.
