350-401 IP SLA Practice Test 2 — 15 Questions

Question 1

A network engineer runs the following command on Router R7:

R7# show ip sla monitor statistics 6

Round Trip Time (RTT) for Index 6
Latest RTT: NoConnection/Busy/Timeout
Latest Operation Start Time: 18:00:00.000 UTC Mon Mar 1 2021
Latest Operation Return Code: Timeout
Number of successes: 0
Number of failures: 15
Over thresholds: 0

Based on this output, what is the status of the IP SLA operation?

Accepted Answer

The target is unreachable, as all probes have timed out.. All 15 probes have failed with a timeout return code, indicating a persistent connectivity issue to the target. The target is likely unreachable.

Answer

The operation is functioning normally with occasional timeouts.

Answer

The target is reachable but with high latency.

Answer

The operation has been configured but not started.

Question 2

A network engineer executes the following command on Router R8:

R8# show ip sla monitor summary

Answer

Forever

Answer

30 seconds

Answer

5000 milliseconds

Question 4

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?

Accepted Answer

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.

Answer

It sends ICMP echo requests to 10.1.1.1 every 10 seconds, but only for 10 minutes.

Answer

It sends ICMP echo requests to 10.1.1.1 every 60 seconds by default.

Answer

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.

Question 5

Consider the following partial configuration on Router R1:

ip sla 2
 icmp-echo 10.2.2.2
 frequency 15
ip sla schedule 2 life forever start-time now
ip sla reaction-configuration 2 react timeout threshold-type immediate action-type triggerOnly

Which statement about this configuration is true?

Accepted Answer

The IP SLA operation will send ICMP echo requests every 15 seconds and trigger an event if a timeout occurs, but the trigger will only activate once.. The 'reaction-configuration' command configures IP SLA to monitor the 'timeout' condition. When a timeout occurs, it triggers an immediate action, but 'triggerOnly' means it only triggers once and does not reset automatically.

Answer

The IP SLA operation will send ICMP echo requests every 15 seconds and continuously trigger events for each timeout.

Answer

The IP SLA operation will send ICMP echo requests every 15 seconds and trigger an event if the round-trip time exceeds a threshold.

Answer

The IP SLA operation will send ICMP echo requests every 15 seconds, but the 'reaction-configuration' command is invalid because it requires a threshold value.

Question 6

Review the following IP SLA configuration on Router R1:

ip sla 3
 icmp-echo 10.3.3.3
 frequency 30
ip sla schedule 3 life forever start-time now
ip sla reaction-configuration 3 react rtt threshold-type xof 5 threshold-value 100 action-type triggerAndReset

What is the purpose of the 'threshold-type xof 5' parameter?

Accepted Answer

It triggers an event if 5 consecutive RTT measurements exceed 100 ms.. 'threshold-type xof 5' means the trigger will occur if 5 consecutive RTT measurements exceed the threshold value of 100 ms. This helps avoid false triggers from transient spikes.

Answer

It triggers an event if 5 out of the last 10 RTT measurements exceed 100 ms.

Answer

It triggers an event if the RTT exceeds 100 ms for 5 seconds.

Answer

It triggers an event if the RTT exceeds 100 ms and then repeats 5 times.

Question 7

Examine this IP SLA configuration on Router R1:

ip sla 4
 icmp-echo 10.4.4.4
 frequency 10
ip sla schedule 4 life forever start-time now
ip sla reaction-configuration 4 react timeout threshold-type immediate action-type triggerOnly

Which of the following is missing from this configuration to make it useful for tracking?

Accepted Answer

A 'track' object that references the IP SLA operation is missing.. IP SLA reaction configurations need to be associated with a tracking object to be useful for actions like route manipulation. Without 'track', the trigger has no effect.

Answer

The 'frequency' command is missing; it should be set to 60 seconds.

Answer

The 'ip sla responder' must be configured on the target router.

Answer

The 'life' parameter should be set to a specific number of repetitions.

Question 8

Consider the following partial configuration on Router R1:

ip sla 5
 icmp-echo 10.5.5.5
 frequency 10
ip sla schedule 5 life forever start-time now
ip sla reaction-configuration 5 react rtt threshold-type immediate threshold-value 200 action-type triggerAndReset

What is the effect of the 'action-type triggerAndReset' parameter?

Accepted Answer

It triggers an event each time the RTT exceeds 200 ms and resets the counter after each trigger.. 'triggerAndReset' means that when the threshold is exceeded, the trigger fires, and then the monitoring resets so it can trigger again on future threshold violations.

Answer

It triggers an event once and then stops monitoring.

Answer

It triggers an event only if the RTT exceeds 200 ms for 5 consecutive probes.

Answer

It triggers an event and then immediately stops the IP SLA operation.

Question 9

Review this IP SLA configuration on Router R1:

ip sla 6
 icmp-echo 10.6.6.6
 frequency 10
ip sla schedule 6 life forever start-time now
ip sla reaction-configuration 6 react timeout threshold-type immediate action-type triggerOnly

Which statement is true about the 'threshold-type immediate' parameter?

Accepted Answer

It triggers an event immediately when a timeout occurs.. 'threshold-type immediate' means the trigger fires as soon as the condition (timeout) occurs, without waiting for multiple occurrences.

Answer

It triggers an event after a delay of 10 seconds.

Answer

It triggers an event only if the timeout persists for 5 consecutive probes.

Answer

It triggers an event only if the timeout occurs within the first 10 seconds.

Question 10

What is the default frequency (in seconds) for an IP SLA ICMP echo operation if not explicitly configured?

Accepted Answer

60 seconds. The default frequency for IP SLA operations, including ICMP echo, is 60 seconds.

Answer

10 seconds

Answer

30 seconds

Answer

120 seconds

Question 11

Which IP SLA operation type requires an IP SLA responder to be configured on the target device?

Accepted Answer

UDP jitter. UDP jitter operations require a responder to accurately measure one-way delay, jitter, and packet loss. ICMP echo does not require a responder.

Answer

ICMP echo

Answer

TCP connect

Answer

HTTP get

Question 12

What is the purpose of the 'ip sla schedule' command in IP SLA configuration?

Accepted Answer

It starts the IP SLA operation and sets its lifetime and start time.. The 'ip sla schedule' command starts an IP SLA operation and defines its lifetime and start time.

Answer

It defines the type of IP SLA operation.

Answer

It sets the frequency of the IP SLA operation.

Answer

It configures threshold monitoring for the IP SLA operation.

Question 13

Drag and drop the steps of configuring an IP SLA UDP jitter operation into the correct order, from first to last.

Accepted Answer

Enter global configuration mode. The correct order begins with entering global configuration mode, then defining the IP SLA operation type and target, setting scheduling parameters, and finally verifying the operation with a show command.

Question 14

Drag and drop the steps of configuring an IP SLA ICMP echo operation into the correct order, from first to last.

Accepted Answer

Enter global configuration mode. First, enter global config mode. Then create the IP SLA operation with type icmp-echo, set the target address and optional parameters like frequency, schedule the operation, and finally verify reachability using show commands.

Question 15

Drag and drop the steps of troubleshooting an IP SLA operation into the correct order, from first to last.

Accepted Answer

Check IP SLA configuration. Start by checking the IP SLA configuration for errors, then verify the operation is scheduled and active. Next, examine the statistics for failures, check reachability to the target, and finally review logs for any system-level issues.
