350-501 Automation and Assurance Practice Question
Exhibit
Refer to the exhibit. ! Output from 'show ip sla summary' ! IP SLAs Summary IPSLA ID: 1 Type: UDP Jitter Destination: 10.2.2.2 Source: 10.1.1.1 Frequency: 10 seconds Threshold: 100 ms Latest RTT: 50 ms Latest Jitter: 5 ms Packet Loss: 0% Over thresholds: 0
Refer to the exhibit. An engineer configures IP SLA for UDP jitter. The operation completes successfully, but the customer reports voice quality issues. What should the engineer check next?
⚠ Common exam trap
Cisco often tests the misconception that a successful IP SLA operation implies no issues, when in fact the threshold configuration can hide performance problems that affect voice quality.
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 threshold is set too high
The IP SLA UDP jitter operation completed successfully, meaning the destination is reachable and the operation is running. However, if the threshold is set too high, the IP SLA will not trigger a reaction (e.g., an SNMP trap or route change) even when jitter exceeds acceptable levels for voice quality. The customer reports voice quality issues, so the engineer must check if the jitter threshold is configured too high, masking the problem.
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 packet loss is 0%
Why it's wrong here
Packet loss is zero now, but jitter can still cause voice issues.
- ✗
The frequency is too low
Why it's wrong here
A 10-second frequency is adequate for voice quality monitoring.
- ✗
The jitter value is within threshold
Why it's wrong here
Current jitter is low, but the threshold is too high to detect spikes that cause voice issues.
- ✗
The destination is unreachable
Why it's wrong here
The operation completes successfully, so the destination is reachable.
- ✓
The threshold is set too high
Why this is correct
A 100 ms threshold is too high for jitter; it should be lowered to trigger alerts when jitter impacts voice quality.
