- A
The 'threshold' command sets the rising threshold that triggers a reaction when exceeded.
Correct because the 'threshold' command defines the upper boundary; when the measured value exceeds it, the reaction is triggered.
- B
The 'reaction' configuration can specify an action such as 'connection-loss' to trigger when the probe fails to receive a response.
Correct because 'connection-loss' is a valid reaction type that activates when the probe does not receive a reply.
- C
The IP SLA reaction can be used to update a tracking object, which can then influence policy-based routing or static route removal.
Correct because the 'track' command can reference an IP SLA operation, and changes in the SLA state can modify routing behavior.
- D
The 'reaction' command supports a 'timeout' type that triggers when the probe response time exceeds a configured value.
Why wrong: Incorrect because 'timeout' is not a reaction type; the correct parameter is 'threshold' for exceeding a value, and 'timeout' is a global probe parameter.
- E
The 'reaction' command can only monitor round-trip time and cannot be used for jitter or packet loss.
Why wrong: Incorrect because the 'reaction' command can monitor various statistics, including jitter (e.g., 'jitter') and packet loss (e.g., 'packet-loss').
Quick Answer
The correct answer is that IP SLA reaction can update a tracking object to influence policy-based routing or static route removal. This works because IP SLA threshold monitoring allows you to define rising and falling thresholds that trigger specific reactions, such as notifying a tracking object when a probe fails or recovers. The tracking object then directly impacts routing decisions, enabling dynamic failover or path selection. On the ENCOR 350-401 exam, this concept tests your understanding of how IP SLA integrates with object tracking to automate network resilience—a common trap is confusing the 'connection-loss' reaction type, which triggers only when all probes in a group fail, with the 'timeout' keyword, which is actually configured within the threshold parameters, not as a standalone reaction type. Remember the memory tip: "Track to react, react to route"—the tracking object is the bridge between IP SLA events and routing changes.
CCNP 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.
Which three statements about IP SLA threshold monitoring and reaction configuration 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
The 'threshold' command sets the rising threshold that triggers a reaction when exceeded.
IP SLA allows configuring rising and falling thresholds to trigger events. The reaction can be tied to a tracking object, which can then influence routing decisions. The 'connection-loss' type triggers when all probes fail. The 'timeout' reaction is not a valid type; the correct keyword is 'timeout' within the threshold configuration. The 'react' command can also monitor jitter values.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.

Same concept, more angles
3 more ways this is tested on 350-401
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which three statements about IP SLA threshold configuration and reaction are true? (Choose three.)
hard- ✓ A.The 'reaction-configuration' command is used to define rising and falling threshold values for an IP SLA operation.
- ✓ B.The 'reaction-trigger' command associates a threshold violation with an action such as enabling a static route.
- ✓ C.When a rising threshold is exceeded, an SNMP trap can be sent to the network management system.
- D.The threshold is based on the number of probes sent within a specified time interval.
- E.If a threshold is violated, the IP SLA operation automatically changes its probe schedule to a higher frequency.
Why A: IP SLA allows configuring rising and falling thresholds to trigger events. The 'reaction-configuration' command sets the threshold values and the action to take when a threshold is crossed. The 'reaction-trigger' command is used to associate the reaction with a specific action, such as enabling a backup route. The threshold violation can be used to trigger an SNMP trap, which is a common method for network management systems to receive alerts. The threshold is not based on the number of probes sent, but on the measured values like delay or jitter. The reaction does not automatically change the probe schedule; it triggers an external action.
Variation 2. Drag and drop each IP SLA reaction action on the left to its corresponding behavior on the right.
medium- ✓ P1.syslog: Send a log message
- ✓ P2.snmp trap: Send an SNMP notification
- ✓ P3.trigger: Start another IP SLA operation
- ✓ P4.none: Disable reaction
- ✓ P5.timeout: Trigger on probe timeout
Why P1: Syslog sends a log message; SNMP trap sends an SNMP notification; trigger starts another IP SLA operation; none disables reaction; timeout triggers on probe timeout.
Variation 3. Drag and drop each IP SLA reaction on the left to its action on the right.
medium- ✓ P1.syslog: Generates a log message
- ✓ P2.snmp trap: Sends an SNMP trap
- ✓ P3.trigger: Starts another IP SLA operation or event
- ✓ P4.react: Enables reaction to threshold violations
- ✓ P5.action-type: Specifies the type of reaction action
Why P1: Syslog generates a log message; SNMP trap sends an SNMP trap; trigger starts another IP SLA operation or event.
