Embedded Event Manager (EEM) →mediumMultiple ChoiceObjective-mapped

Quick Answer

The problem is that the configuration incorrectly applies the `entry-op` and `entry-val` keywords to a scalar OID, which are only valid for table entries. In EEM, the `event snmp oid` command uses `get-type exact` to monitor a specific scalar instance, but `entry-op` and `entry-val` are designed to filter against multiple rows in an SNMP table, not a single scalar value like `cpmCPUTotal5sec`. This is a common trap on the Cisco CCNP ENARSI 300-410 exam, testing your understanding of how EEM distinguishes between scalar and tabular OIDs in SNMP monitoring. Many candidates mistakenly apply table-entry logic to scalars, causing the applet to never trigger or to fail silently. Remember the memory tip: "Scalars are single values, so skip the entry-op; tables need the op to stop the flop."

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.

Consider the following EEM applet configuration:

!--- event manager applet HIGH_CPU event snmp oid 1.3.6.1.4.1.9.9.109.1.1.1.1.3.1 get-type exact entry-op gt entry-val 90 poll-interval 10 action 1.0 syslog msg "CPU utilization exceeded 90%" !---

What is the problem with this configuration?

A
The OID is a scalar, so 'entry-op' and 'entry-val' cannot be used; they are only for table entries.
Correct. For scalar OIDs, the 'entry-op' and 'entry-val' are not applicable; the applet should use a different event type or specify the OID correctly.
B
The 'poll-interval' is too short and will cause high CPU usage.
Why wrong: Incorrect. The poll interval of 10 seconds is acceptable; the issue is with the use of 'entry-op' and 'entry-val'.
C
The applet will work correctly and generate a syslog message when CPU exceeds 90%.
Why wrong: Incorrect. The configuration is invalid because 'entry-op' and 'entry-val' are not supported for scalar OIDs.
D
The 'get-type exact' is incorrect; it should be 'get-type next'.
Why wrong: Incorrect. 'get-type exact' is valid for scalar OIDs; the problem is the use of 'entry-op' and 'entry-val'.

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

✓

The OID is a scalar, so 'entry-op' and 'entry-val' cannot be used; they are only for table entries.

The 'event snmp oid' command requires a 'get-type' of 'exact' or 'next', but the OID specified is for a specific instance (cpmCPUTotal5sec). However, the OID is not complete; it should include the instance index. Additionally, the 'entry-op' and 'entry-val' are used for table entries, but this OID is a scalar. The correct approach is to use 'event snmp oid' with a scalar OID and use 'poll-interval' with 'entry-op' and 'entry-val' only for table entries. This configuration may cause the applet to not trigger correctly.

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

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
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 300-410 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.
