350-501 Automation and Assurance Practice Question
An SP customer reports intermittent voice quality issues. The engineer wants to measure jitter and packet loss between two remote sites using Cisco IP SLA. Which IP SLA operation type should be configured?
⚠ Common exam trap
Cisco often tests the misconception that ICMP Echo (ping) can measure jitter, but ICMP does not provide per-packet timestamps or loss differentiation between directions, making it unsuitable for voice quality diagnostics.
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
✓
UDP Jitter
The UDP Jitter operation (option E) is correct because it measures both one-way jitter and packet loss by sending UDP packets with precise timestamps, which is essential for diagnosing voice quality issues. Unlike other IP SLA operations, UDP Jitter specifically tracks inter-packet delay variation (jitter) and loss patterns that directly impact VoIP and real-time traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
DNS Query
Why it's wrong here
DNS Query measures DNS resolution time, not relevant for voice quality.
- ✗
ICMP Echo
Why it's wrong here
ICMP Echo only measures round-trip time, not jitter or packet loss.
- ✗
HTTP Get
Why it's wrong here
HTTP Get measures HTTP server response time, not network jitter.
- ✗
TCP Connect
Why it's wrong here
TCP Connect measures TCP connection setup time, not jitter or loss.
- ✓
UDP Jitter
Why this is correct
UDP Jitter measures jitter, packet loss, and one-way delay, ideal for voice quality monitoring.
