200-901 Cisco Platforms and Development Practice Question
This 200-901 practice question tests your understanding of cisco platforms and development. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE of the following are valid event triggers for an EEM applet on Cisco IOS XE? (Choose THREE.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
timer
Option A is correct because EEM applets support timer-based event triggers, such as absolute time, countdown, or watchdog timers, allowing automation of actions at specified intervals or after a delay. This is a core EEM feature defined in Cisco IOS XE for scheduling tasks without external input.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the exact EEM event trigger keywords, and candidates mistakenly assume 'snmp trap' is valid because SNMP traps are common network events, but the correct trigger is 'event snmp notification' or 'event snmp oid', not 'trap'.
Detailed technical explanation
How to think about this question
EEM applets use event detectors like 'event timer', 'event cli', and 'event syslog' to register interest in specific system occurrences. The 'event cli' trigger matches a regular expression against entered commands, while 'event syslog' parses syslog messages for a pattern; both are registered with the EEM server, which polls or receives callbacks from the respective subsystems. In production, timer-based triggers are commonly used for periodic health checks, and syslog pattern triggers for automated responses to critical log messages like interface flaps.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
