Which TWO statements about IP SLA ICMP echo operations are true? (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
✓
It measures round-trip time (RTT) between the source and destination.
IP SLA ICMP echo measures round-trip time (RTT) by sending ICMP echo requests and waiting for replies. It does not measure jitter (that requires UDP jitter operations). It can be configured with a frequency and a timeout, and the operation must be started with the 'ip sla schedule' command. The source IP can be specified, but the destination must be an IP address, not a hostname unless DNS resolution is configured.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It measures round-trip time (RTT) between the source and destination.
Why this is correct
The ICMP echo operation sends ICMP packets and calculates the RTT based on the reply.
- ✗
It measures jitter in the network path.
Why it's wrong here
Jitter measurement requires a UDP jitter operation, not ICMP echo.
- ✓
The operation must be scheduled using the 'ip sla schedule' command.
Why this is correct
After configuring the operation, it must be scheduled to start and optionally repeat.
- ✗
The destination can be specified as a hostname without any additional configuration.
Why it's wrong here
The destination must be an IP address unless DNS is configured; hostnames are not automatically resolved.
- ✗
The operation runs continuously by default after configuration.
Why it's wrong here
The operation does not start automatically; it must be scheduled.

Same concept, more angles
1 more way this is tested on 300-410
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 TWO commands are used to configure an IP SLA ICMP echo operation on a Cisco IOS device? (Choose TWO.)
easy- ✓ A.ip sla 1
- ✓ B.icmp-echo 192.168.1.1 source-ip 10.0.0.1
- C.ip sla schedule 1 life forever start-time now
- D.track 1 ip sla 1 reachability
- E.ip sla monitor 1
Why A: To configure an IP SLA ICMP echo operation, you start with 'ip sla <operation-number>' to enter IP SLA configuration mode, then use 'icmp-echo <destination> [source-ip <src>]' to define the probe. The 'frequency' command sets how often the probe is sent. The 'ip sla schedule' is used to start the operation, not to configure it. The 'track' command is used separately to monitor the operation. The 'ip sla monitor' is legacy.
