- A
ICMP Echo
Why wrong: ICMP Echo only tests reachability to a single destination, not the path.
- B
ICMP Path Echo
Correct. ICMP Path Echo discovers the path by incrementing TTL.
- C
UDP Jitter
Why wrong: UDP Jitter does not trace the path.
- D
TCP Connect
Why wrong: TCP Connect does not trace the path.
Question 1,525 of 2,152
IP SLA ICMP Path Echo Operation: Discover Network Path
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 uses ICMP to discover the path (hops) between source and destination?
Quick Answer
The answer is ICMP Path Echo. This IP SLA operation type uses ICMP to discover the network path between source and destination by sending ICMP Echo requests with incrementally increasing TTL values, exactly like a traceroute, and recording each hop’s response. On the Cisco CCNP ENARSI 300-410 exam, this question tests your understanding of IP SLA operation types for path discovery, often appearing alongside other types like UDP Jitter or ICMP Echo; a common trap is confusing ICMP Path Echo with standard ICMP Echo, which only measures reachability and round-trip time, not the hop-by-hop path. Remember that the operation number is type 10, and think of “Path Echo” as “traceroute in IP SLA” — the TTL trick is the key mechanism. A simple memory tip: “Path Echo traces the route, Echo just pings the root.”

Correct answer & explanation
✓
ICMP Path Echo
The ICMP Path Echo operation (type 10) uses ICMP Echo requests with increasing TTL values to trace the path from source to destination, similar to traceroute.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
