Exam 350-601 topic 1 question 215 discussion

Isn't it D? From the book "If you want to allow the triggered event to process any default actions, you must configure the EEM policy to allow the default action. For example, if you match a CLI command in a match statement, you must add the event-default action statement to the EEM policy; otherwise, EEM will not allow the CLI command to execute."

Correct answer is D. Tested in my lab. Once you apply this configuration you will not be able to run the "copy running-config startup-config" because it will get blocked since this event doesn't have an action. A is incorrect. "Applying" this configuration will not generate an error.

“If you want to allow the triggered event to process any default actions, you must configure the EEM policy to allow the default action. For example, if you match a CLI command in a match statement, you must add the event-default action statement to the EEM policy; otherwise, EEM will not allow the CLI command to execute.”

Wow, these comments are hilarious. It is literally D. It is even in black and white when you click the show answer and gives an explanation with verified lab evidence: "% Command blocked by event manager policy" There is even a user below that ran it in their lab and still suggests "A" while their output has the "% Command blocked by event manager policy" at the end of his output. :) Answer is D.

If an action is not explicitly specified in an EEM (Embedded Event Manager) applet, the default behavior can vary depending on the platform and the specific configuration. In some cases, if no action is defined, the EEM applet may have a minimal or default response, such as logging the event or generating a message indicating that the event was triggered.

D is the one!

It blocks the copy running-config startup-config command.

D is the right answer, I've tested it on the lab

Answer is D. event timer command triggers an event if the specified time is reached. The range for the time is from 1 to 4294967295. • absolute time—Triggers an event when the specified absolute time of day occurs. • countdown time—Triggers an event when when the specified time counts down to zero. The timer does not reset. • cron cronentry—Triggers an event when the CRON string specification matches the current time. • watchdog time—Triggers an event when the specified time counts down to zero. The timer automatically resets to the initial value and continues to count down. If you want to allow a triggered event to process any default actions, you must configure the EEM policy to allow the default action. For example, if you match a CLI command in a match statement, you must add the event-default action statement to the EEM policy or EEM will not allow the CLI command to execute.

A - is correct answer. switch# show run | i event event manager applet Backup-config event cli match "copy running-config startup-config" action 1 event-default switch# switch# copy run start [########################################] 100% Copy complete, now saving to disk (please wait)... Copy complete. switch# conf t Enter configuration commands, one per line. End with CNTL/Z. switch(config)# event manager applet Backup-config switch(config-applet)# no action 1 switch(config-applet)# end switch# show run | i event event manager applet Backup-config event cli match "copy running-config startup-config" switch# copy run start % Command blocked by event manager policy switch#

i have created many EEM scripts and the answer A is correct through process of elimination. the EEM needs an action or nothing happens. im not sure if an error is created because mine work but its not any of the other answers. also, if you look at the match command, its not an action but a match so i cant see how any of the other answers are correct.

Actually, had a closer look at this and the answer is A - no action statement is configured - just two trigger events - ie the timer expiring and someone typing copy run st.

It should be C
