This 300-410 practice question tests your understanding of ip sla. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
A network engineer runs the following command on Router R1:
R1# show ip sla statistics 3
Round Trip Time (RTT) for Index 3
Latest RTT: 150 ms
Latest RTT (milliseconds): 150
Latest RTT (microseconds): 150000
Number of successes: 80
Number of failures: 20
Operation time to live: Forever
Output: OK
R1# show track 1
Track 1
IP SLA 3 reachability
Reachability is Up
2 changes, last change 00:00:10
Latest operation return code: OK
Latest RTT (milliseconds): 150
Tracked by:
ip route 0.0.0.0 0.0.0.0 192.168.1.1 track 1
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 is considered reachable, and the tracked static route is active.
The track shows 'Reachability is Up' based on IP SLA 3. The IP SLA statistics show successes and failures, but the latest return code is OK, so the track is up. This means the static route is active. The failures (20) indicate some probes failed, but the track still considers it reachable because the threshold for reachability is likely based on a percentage or consecutive failures.
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
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The static route is removed because the IP SLA operation has failures.
Why it's wrong here
The track is up, so the static route remains. Failures alone do not bring the track down unless they exceed a threshold.
✓
The IP SLA operation is considered reachable, and the tracked static route is active.
Why this is correct
The track shows 'Up', meaning the IP SLA is reachable, and the static route is installed.
Related concept
Read the scenario before looking for a memorised answer.
✗
The IP SLA operation has a 20% failure rate, so the track should be down.
Why it's wrong here
The track is up, so the failure rate is within the configured threshold. The track does not automatically go down with failures.
✗
The IP SLA operation is using a wrong source address.
Why it's wrong here
There is no indication of source address issues; the operation is succeeding.
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.
