Quick Answer
The answer is the UDP Jitter operation, specifically type 3. This IP SLA operation type is designed to measure one-way delay, jitter, and packet loss because it sends UDP packets embedded with sequence numbers and precise timestamps, allowing the destination device to calculate the exact time each packet took to arrive and detect any variation in inter-packet arrival times. On the Cisco CCNP ENARSI 300-410 exam, this concept tests your understanding of how IP SLA probes differ by metric—for instance, while ICMP echo measures round-trip time, only UDP Jitter provides the one-way metrics required for voice and video troubleshooting. A common trap is confusing this with the UDP Echo operation, which only verifies connectivity and round-trip delay, not one-way jitter or packet loss. Remember the memory tip: "Jitter needs timestamps and sequence numbers to catch the wobble," so when you see those keywords in a question, lock in UDP Jitter.
This 300-410 practice question tests your understanding of ip sla. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which IP SLA operation type is specifically designed to measure one-way delay, jitter, and packet loss using UDP packets with sequence numbers and timestamps?
UDP Echo
Why wrong: UDP Echo measures round-trip time, not one-way metrics.
UDP Jitter
Correct. UDP Jitter is designed for one-way delay, jitter, and packet loss measurement.
ICMP Path Echo
Why wrong: ICMP Path Echo traces the path, not jitter or one-way delay.
TCP Connect
Why wrong: TCP Connect measures connection setup time, not jitter.

Correct answer & explanation
UDP Jitter
The UDP Jitter operation (type 3) sends UDP packets with embedded sequence numbers and timestamps to measure one-way delay, jitter, and packet loss between source and destination.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 300-410 NAT questions on configuration and troubleshooting.
