CCNP IP SLA Practice Question

This 350-401 practice question tests your understanding of ip sla. 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 partial configuration on Router R1:

ip sla 2

icmp-echo 10.2.2.2 frequency 15

ip sla schedule 2 life forever start-time now
ip sla reaction-configuration 2 react timeout threshold-type immediate action-type triggerOnly

Which statement about this configuration is true?

Question 1mediummultiple choice

Review the full routing breakdown →

A
The IP SLA operation will send ICMP echo requests every 15 seconds and trigger an event if a timeout occurs, but the trigger will only activate once.
'threshold-type immediate' triggers as soon as a timeout occurs, and 'action-type triggerOnly' ensures it triggers only once.
B
The IP SLA operation will send ICMP echo requests every 15 seconds and continuously trigger events for each timeout.
Why wrong: 'action-type triggerOnly' limits the trigger to one occurrence; for continuous triggering, 'action-type triggerAndReset' would be used.
C
The IP SLA operation will send ICMP echo requests every 15 seconds and trigger an event if the round-trip time exceeds a threshold.
Why wrong: The 'react timeout' monitors for timeouts, not round-trip time thresholds. For RTT thresholds, 'react rtt' would be used.
D
The IP SLA operation will send ICMP echo requests every 15 seconds, but the 'reaction-configuration' command is invalid because it requires a threshold value.
Why wrong: The command is valid; 'threshold-type immediate' does not require a numeric threshold value.

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

✓

The IP SLA operation will send ICMP echo requests every 15 seconds and trigger an event if a timeout occurs, but the trigger will only activate once.

The 'reaction-configuration' command configures IP SLA to monitor the 'timeout' condition. When a timeout occurs, it triggers an immediate action, but 'triggerOnly' means it only triggers once and does not reset automatically.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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.

Trap categories for this question

Command / output trap
The command is valid; 'threshold-type immediate' does not require a numeric threshold value.

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 350-401 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.

What to study next
