300-410 Practice Question: Which TWO statements correctly describe the…
Which TWO statements correctly describe the behavior of IP SLA with the 'threshold' and 'timeout' configuration? (Choose TWO.)
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
✓
The 'threshold' value must be less than the 'timeout' value for the reaction to trigger correctly.
The 'threshold' command sets the rising threshold for reaction triggering, while 'timeout' specifies how long the probe waits for a response before marking the operation as a failure. The timeout must be less than the frequency interval; otherwise, the probe may overlap. The default timeout is 5000 ms, not 10000 ms.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The 'threshold' value must be less than the 'timeout' value for the reaction to trigger correctly.
Why this is correct
Correct. The threshold is the value that triggers a reaction event; it must be lower than the timeout to allow the reaction to occur before the operation times out.
- ✓
The 'timeout' value must be less than the 'frequency' value to prevent overlapping probes.
Why this is correct
Correct. If timeout exceeds frequency, a new probe may start before the previous one completes, causing overlapping and unreliable results.
- ✗
The default timeout for an IP SLA ICMP echo operation is 10000 milliseconds.
Why it's wrong here
Incorrect. The default timeout is 5000 milliseconds (5 seconds), not 10000 ms.
- ✗
The 'threshold' value is used to set the maximum number of retries before the operation is considered failed.
Why it's wrong here
Incorrect. The threshold is a time-based value (in milliseconds) for triggering reactions; retries are configured separately with the 'threshold' command in the reaction configuration.
- ✗
If the 'timeout' is set to 3000 ms and the 'frequency' is set to 5 seconds, the probe will never overlap.
Why it's wrong here
Incorrect. Although 3000 ms (3 seconds) is less than 5 seconds, the statement is technically true but not a general behavior description; the question asks for correct descriptions, and this is a specific scenario, not a general rule. However, the key point is that the 'timeout' must be less than 'frequency' to avoid overlap, which is already covered in option B. Option E is not a standard statement about IP SLA behavior.
