350-401 Practice Question: Which three statements about IP SLA UDP jitter…
Which three statements about IP SLA UDP jitter operation are true? (Choose three.)
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 operation measures one-way delay, jitter, and packet loss between source and destination.
UDP jitter operation measures one-way delay, jitter, and packet loss by sending timestamped UDP packets. It requires the IP SLA responder on the destination. The operation can be configured with a codec type to simulate voice traffic. The 'num-packets' command sets the number of packets in each probe. The operation does not measure TCP throughput.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
UDP jitter operation measures one-way delay, jitter, and packet loss between source and destination.
Why this is correct
Correct because the UDP jitter operation calculates these metrics using timestamps in the probe packets.
- ✓
The IP SLA responder must be enabled on the destination device for UDP jitter to function correctly.
Why this is correct
Correct because the responder provides accurate timestamping and reply generation necessary for jitter calculation.
- ✓
The UDP jitter operation can be configured with a codec type (e.g., G.711) to simulate specific voice traffic patterns.
Why this is correct
Correct because the 'codec' parameter allows the operation to mimic the packet size and rate of a particular codec.
- ✗
The 'num-packets' command in UDP jitter configuration sets the total number of probes to be sent over the entire operation lifetime.
Why it's wrong here
Incorrect because 'num-packets' sets the number of packets per probe, not the total over the lifetime.
- ✗
UDP jitter operation can measure TCP window scaling and throughput.
Why it's wrong here
Incorrect because UDP jitter is a UDP-based operation and does not measure TCP-specific parameters.
