Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 98

An engineer is asked to monitor the availability of the next-hop IP address of 172.16.201.25 every 3 seconds using an ICMP echo packet via an ICMP echo probe.
Which two commands accomplish this task? (Choose two.)

Answer options

• A. router(config-ip-sla)#icmp-echo 172.16.201.25 source-interface FastEthernet 0/0
• B. router(config-ip-sla-echo)#timeout 3
• C. router(config-ip-sla)#icmp-jitter 172.16.201.25 interval 100 D. router(config-ip-sla-echo)#frequency 3
• D. router(config-ip-sla)#udp-echo 172.16.201.25 source-port 23 F. router(config-ip-sla-echo)#threshold 3

Correct answer: A, D

Explanation

The correct commands are A and D. Command A sets up an ICMP echo probe to the specified IP address, and command D specifies the frequency of the probe to be every 3 seconds. The other options either do not configure an ICMP echo probe or set parameters unrelated to the task at hand.
