- A
The threshold value is too low, causing frequent threshold violations.
Why wrong: While the threshold is low, it is not necessarily a problem; it depends on the network. The source address issue is more critical.
- B
The source address is set to 0.0.0.0, which may cause the probe to fail if the router does not have a valid route.
A source address of 0.0.0.0 means the router uses the IP of the egress interface, but if that interface is down or has no IP, the probe may fail. This is a common misconfiguration.
- C
The frequency is set to 10 seconds, which is too fast for accurate measurements.
Why wrong: A 10-second frequency is typical and not inherently problematic.
- D
The operation timeout is too high, causing delays in failure detection.
Why wrong: A 5000 ms timeout is reasonable; it does not cause a direct problem.
300-410 IP SLA Practice Question
This 300-410 practice question tests your understanding of ip sla. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 configuration 1 IP SLAs Infrastructure Engine-II
Entry number: 1 Owner: Tag: Type of operation to perform: icmp-echo Target address: 192.168.1.1 Source address: 0.0.0.0 Source interface: none Type Of Service parameter: 0 Verify data: No Operation timeout (milliseconds): 5000 Request size (ARR data block): 28 Threshold (milliseconds): 100 Frequency (seconds): 10 Life (seconds): Forever Ageout (seconds): 0
Based on this output, what is the primary problem with this IP SLA configuration?

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 source address is set to 0.0.0.0, which may cause the probe to fail if the router does not have a valid route.
The source address is 0.0.0.0 and no source interface is configured. This means the router will use the outgoing interface's IP address, which might not be routable or expected. However, the key clue is that the threshold is set to 100 ms, but the operation timeout is 5000 ms. If the RTT exceeds 100 ms, the operation will report 'Over threshold' but not necessarily fail. The question focuses on configuration issues; the source address being 0.0.0.0 is a common misconfiguration that can cause problems if the router cannot reach the target.
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 threshold value is too low, causing frequent threshold violations.
Why it's wrong here
While the threshold is low, it is not necessarily a problem; it depends on the network. The source address issue is more critical.
- ✓
The source address is set to 0.0.0.0, which may cause the probe to fail if the router does not have a valid route.
Why this is correct
A source address of 0.0.0.0 means the router uses the IP of the egress interface, but if that interface is down or has no IP, the probe may fail. This is a common misconfiguration.

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.
