- A
An EEM applet can be triggered by multiple event types if the 'event' statements are configured under the same applet using the 'multiple' keyword.
Correct. The 'event multiple' keyword allows an applet to wait for any of several specified events.
- B
The 'action info type routername' command stores the router hostname in the '$_info_type_routername' environment variable.
Correct. This action retrieves the router hostname and stores it in the variable '$_info_type_routername'.
- C
The 'event cli' pattern matching is case-insensitive by default.
Why wrong: Incorrect. The default pattern matching for 'event cli' is case-sensitive.
- D
The 'event timer countdown' command uses the 'time' keyword to specify the duration in seconds.
Why wrong: Incorrect. The correct keyword is 'countdown-time', not 'time'.
- E
The 'action string' command can be used to trim leading and trailing whitespace from a variable using the 'trim' subcommand.
Why wrong: Incorrect. The 'action string' command does not have a 'trim' subcommand; trimming is done via 'regexp' or other methods.
Quick Answer
The correct answer is that the 'action info type routername' command stores the router hostname in the '$_info_type_routername' environment variable, and EEM applets can be configured with multiple events using the 'multiple' keyword. This is accurate because the 'action info' command retrieves system information and populates predefined environment variables, while the 'multiple' keyword allows an applet to trigger on several distinct events, such as a CLI pattern and a timer, within a single configuration. On the Cisco CCNP ENARSI 300-410 exam, this topic tests your ability to distinguish between valid EEM applet syntax and common distractors, like the case-sensitive 'event cli' pattern or the incorrect use of 'time' with 'event timer countdown'. A frequent trap is assuming 'action string' supports a 'trim' subcommand, which it does not. Remember the memory tip: "Info stores, multiple opens"—the 'info' action populates variables, and 'multiple' expands event triggers.
300-410 Embedded Event Manager (EEM) Practice Question
This 300-410 practice question tests your understanding of embedded event manager (eem). This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 TWO statements about EEM applet configuration and execution are correct? (Choose TWO.)
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
An EEM applet can be triggered by multiple event types if the 'event' statements are configured under the same applet using the 'multiple' keyword.
EEM applets can be configured with multiple events using the 'multiple' keyword. The 'action info type routername' command retrieves the router hostname. The 'event cli' pattern is case-sensitive by default. The 'event timer countdown' does not support the 'time' keyword; it uses 'countdown-time'. The 'action string' does not support 'trim' as a subcommand.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Why this is correct
Correct. The 'event multiple' keyword allows an applet to wait for any of several specified events.
Related concept

Why this is correct
Correct. This action retrieves the router hostname and stores it in the variable '$_info_type_routername'.

The 'event cli' pattern matching is case-insensitive by default.
Why it's wrong here
Incorrect. The default pattern matching for 'event cli' is case-sensitive.
- ✗
The 'event timer countdown' command uses the 'time' keyword to specify the duration in seconds.
Why it's wrong here
Incorrect. The correct keyword is 'countdown-time', not 'time'.
- ✗

Why it's wrong here
Incorrect. The 'action string' command does not have a 'trim' subcommand; trimming is done via 'regexp' or other methods.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Keyword trap
Incorrect. The correct keyword is 'countdown-time', not 'time'.
Command / output trap
Incorrect. The 'action string' command does not have a 'trim' subcommand; trimming is done via 'regexp' or other methods.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
