300-410 Practice Question: Runs the following command on Router R1: R1# show…
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.
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.
- ✗
The frequency is set to 10 seconds, which is too fast for accurate measurements.
Why it's wrong here
A 10-second frequency is typical and not inherently problematic.
- ✗
The operation timeout is too high, causing delays in failure detection.
Why it's wrong here
A 5000 ms timeout is reasonable; it does not cause a direct problem.
