Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureMedium
A network administrator is configuring a Cisco router to automatically perform a series of commands if a specific event occurs, such as an interface going down or a high CPU utilization threshold being crossed. This automation should execute a predefined script on the router itself. Which Cisco IOS feature allows for this type of event-driven automation?
- ANetFlow
- BEEM
- CSyslog
- DSNMP Traps
Show answer & explanationAnswer & explanation
Correct answer: B. EEM
Embedded Event Manager (EEM) is a powerful, flexible feature in Cisco IOS that allows network administrators to automate tasks by defining policies that trigger actions based on various network events. This is ideal for self-healing networks and proactive troubleshooting.
Why the other options are wrong
- A. NetFlow collects IP traffic statistics, used for monitoring and analysis, not for event-driven automation.
- C. Syslog collects and sends log messages to a server, providing historical data, but doesn't automate actions on the device.
- D. SNMP Traps send notifications to a network management station when an event occurs, but they don't execute commands on the device itself.
Embedded Event Manager (EEM)
A Cisco IOS feature that allows network devices to perform automated actions (e.g., execute commands, send alerts) in response to specific system events or thresholds being met.
- Provides on-device automation and self-healing capabilities.
- Triggers include syslog messages, interface status, CPU usage, etc.
- Actions can be CLI commands, Tcl scripts, SNMP traps, etc.
