- A
It sends ICMP echo requests to 10.1.1.1 every 10 seconds, starting immediately and running forever.
The 'frequency 10' sets the interval to 10 seconds, 'start-time now' starts it immediately, and 'life forever' keeps it running indefinitely.
- B
It sends ICMP echo requests to 10.1.1.1 every 10 seconds, but only for 10 minutes.
Why wrong: The 'life forever' parameter makes the operation run indefinitely, not for a limited time.
- C
It sends ICMP echo requests to 10.1.1.1 every 60 seconds by default.
Why wrong: The 'frequency 10' overrides the default of 60 seconds, setting it to 10 seconds.
- D
It sends ICMP echo requests to 10.1.1.1 every 10 seconds, but only if an IP SLA responder is configured on the target.
Why wrong: ICMP echo operations do not require an IP SLA responder; they use standard ICMP.
Quick Answer
The answer is that this configuration sends ICMP echo requests to 10.1.1.1 every 10 seconds, starting immediately and running forever. This is correct because the ip sla 1 command creates an IP SLA operation, and the icmp-echo 10.1.1.1 command defines the probe type and destination, while the frequency 10 command sets the interval between probes to 10 seconds. The ip sla schedule 1 life forever start-time now command then activates the operation immediately and keeps it running indefinitely, which is the standard way to enable continuous reachability monitoring. On the ENCOR 350-401 exam, this tests your understanding of IP SLA ICMP echo basic configuration as a fundamental network monitoring tool, often appearing in troubleshooting or automation scenarios. A common trap is confusing frequency with timeout—frequency controls how often probes are sent, not how long the operation waits for a reply. Remember the memory tip: “Frequency is the gap, not the nap”—it dictates the interval between echoes, not the response wait time.
350-401 IP SLA Practice Question
This 350-401 practice question tests your understanding of ip sla. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Examine the following IP SLA configuration:
ip sla 1
icmp-echo 10.1.1.1 frequency 10
ip sla schedule 1 life forever start-time now
What is the effect of this configuration?

Correct answer & explanation
It sends ICMP echo requests to 10.1.1.1 every 10 seconds, starting immediately and running forever.
This configuration creates an IP SLA operation that sends ICMP echo requests to 10.1.1.1 every 10 seconds and schedules it to run immediately and indefinitely.

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 350-401 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.
