Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  action 1.0 event "..."

  Why it's wrong here

  The event action defines the trigger that starts the applet, not the response to it. It is tempting because every applet needs an event clause, but the question asks which action executes a CLI command once triggered, and event only registers the trigger condition.

• ✗

  action 1.0 set 1.0 "..."

  Why it's wrong here

  The set action assigns a value to an EEM variable; it does not push a CLI command to the device. It is tempting because set is used to build strings that later actions consume, but executing the command itself requires the cli action, which set cannot substitute.

• ✓

  action 1.0 cli command "..."

  Why this is correct

  The `action 1.0 cli command` statement runs an EXEC-mode CLI command when the applet's event fires, satisfying the requirement to execute a command on trigger. The `cli` keyword specifies the action type, while `command` supplies the exact string to run, distinguishing it from other actions such as `syslog` or `reload`.

• ✗

  action 1.0 syslog msg "..."

  Why it's wrong here

  The syslog action writes a message to the logging buffer; it never enters configuration or exec mode to run a command. It is tempting because syslog is the standard way to record that an event fired, but the scenario needs the CLI command executed, which only the cli action performs.
