Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 501

An engineer received a ticket about a router that has reloaded. The monitoring system graphs show different traffic patterns between logical and physical interfaces when the router is rebooted. Which action resolves the issue?

Answer options

• A. Configure the snmp ifindex persist command on the physical interfaces.
• B. Clear the logical interfaces with snmp ifindex clear command.
• C. Trigger a new snmpwalk from the monitoring system to synchronize interface OIDs.
• D. Configure the snmp ifindex persist command globally.

Correct answer: D

Explanation

The correct answer is D because configuring the snmp ifindex persist command globally ensures that the interface index remains consistent across reboots, preventing discrepancies. Options A and B only address specific interfaces and do not provide a comprehensive solution, while option C does not resolve the underlying issue of interface index persistence.
