Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureMedium
A network engineer needs to configure a Cisco router to automatically perform a series of commands if the CPU utilization exceeds 90% for a sustained period. This automation should also log a message to syslog. Which Cisco feature should the engineer use to implement this proactive monitoring and automated response?
- AEmbedded Event Manager (EEM)
- BSNMP traps
- CNetFlow
- DIP SLA
Show answer & explanationAnswer & explanation
Correct answer: A. Embedded Event Manager (EEM)
Embedded Event Manager (EEM) allows a Cisco device to monitor events (like high CPU utilization) and take automated actions, such as executing a series of commands or sending syslog messages, based on predefined policies.
Why the other options are wrong
- B. SNMP traps are used to send notifications to a network management station but do not automate command execution on the device itself.
- C. NetFlow collects IP traffic flow statistics and is not used for event-driven automation of router actions.
- D. IP SLA (Service Level Agreement) monitors network performance and reachability but does not automate router configuration changes based on internal events like CPU utilization.
Embedded Event Manager (EEM)
A powerful and flexible feature on Cisco devices that provides the ability to automate tasks and customize event-driven actions.
- Monitors various system-level and network-level events.
- Triggers actions like executing CLI commands, sending emails, or generating SNMP traps.
- Allows for proactive issue resolution and customized automation.
Memory trick: EEM is the router's smart assistant, taking action when events happen.
