Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 324

An engineer must create an EEM script to enable OSPF debugging in the event the OSPF neighborship goes down. Which script must the engineer apply?

Answer options

• A. event manager applet ENABLE_OSPF_DEBUG event syslog pattern "%OSPF-5-ADJCHG: Process 6, Nbr 1.1.1.1 on Serial0/0 from FULL to DOWN" action 1.0 cli command "enable" action 2.0 cli command "debug ip ospf event" action 3.0 cli command "debug ip ospf adj" action 4.0 syslog priority informational msg "ENABLE_OSPF_DEBUG"
• B. event manager applet ENABLE_OSPF_DEBUG event syslog pattern "%OSPF-5-ADJCHG: Process 5, Nbr 1.1.1.1 on Serial0/0 from LOADING to FULL" action 1.0 cli command "debug ip ospf event" action 2.0 cli command "debug ip ospf adj" action 3.0 syslog priority informational msg "ENABLE_OSPF_DEBUG"
• C. event manager applet ENABLE_OSPF_DEBUG event syslog pattern "%OSPF-1-ADJCHG: Process 5, Nbr 1.1.1.1 on Serial0/0 from FULL to DOWN" action 1.0 cli command "debug ip ospf event" action 2.0 cli command "debug ip ospf adj" action 3.0 syslog priority informational msg "ENABLE_OSPF_DEBUG"
• D. event manager applet ENABLE_OSPF_DEBUG event syslog pattern "%OSPF-5-ADJCHG: Process 5, Nbr 1.1.1.1 on Serial0/0 from LOADING to FULL" action 1.0 cli command "enable" action 2.0 cli command "debug ip ospf event" action 3.0 cli command "debug ip ospf adj" action 4.0 syslog priority informational msg "ENABLE_OSPF_DEBUG"

Correct answer: A

Explanation

The correct option, A, specifies the right syslog pattern that triggers the script when the OSPF neighbor goes from FULL to DOWN, which is essential for debugging. Options B and D have incorrect patterns that do not represent a neighbor going down, while option C also has an incorrect process number and does not include the required enable command before debugging.
