Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureHard
A network administrator needs to automate a recurring task on a Cisco router: every Sunday at 3:00 AM, the router should clear its BGP neighbor statistics and then send an email notification to the network operations team upon completion. This automation needs to be performed directly on the router without external scripting servers. Which Cisco feature allows for this type of on-device automation and event-driven scripting?
- ACron jobs
- BEmbedded Event Manager (EEM)
- CPython scripting
- DGuest Shell
Show answer & explanationAnswer & explanation
Correct answer: B. Embedded Event Manager (EEM)
Embedded Event Manager (EEM) is a Cisco IOS feature that allows for on-device event detection and automation. It can monitor various events (like time-of-day, syslog messages, interface status) and trigger predefined actions, including executing CLI commands, sending email notifications, or running Tcl/Python scripts, directly on the router.
Why the other options are wrong
- A. Cron jobs are a Linux/Unix utility for scheduling tasks, not a native Cisco IOS feature for this level of event-driven automation.
- C. While some modern Cisco devices support Python scripting, EEM is the specific feature designed for event-driven automation and integrating scripts with IOS events.
- D. Guest Shell is a Linux container on some Cisco devices for running Linux applications, not primarily for native IOS event automation.
Embedded Event Manager (EEM)
A Cisco IOS feature that provides on-device event detection and automation, allowing network devices to react to events and perform predefined actions without external intervention.
- Monitors various events (e.g., syslog, interface status, timers, counters).
- Triggers actions such as executing CLI commands, sending email, or running scripts (Tcl/Python).
- Enables proactive troubleshooting and self-healing capabilities directly on the device.
