Refer to the exhibit. An engineer configured IP SLA on R1 to avoid the ISP link flapping problem, but it is not working as designed. IP SLA should wait 30 seconds before switching traffic to a secondary connection and then revert to the primary link after waiting 20 seconds, when the primary link is available and stabilized.


Which configuration resolves the issue?


  1. R1(config)#track 700 ipsla 700
    R1 (config-track)#delay down 30 up 20

  2. R1 (config)#ipsla 700
    R1(config-ip-sla)#delay down 30 up 20

  3. R1 (config)#ipsla 700
    R1(config-ip-sla)#delay down 20 up 30

  4. R1(config)#track 700 ipsla 700
    R1(config-track)#delay down 20 up 30

Answer(s): A

  1. check cable-diagnostics tdr interface GigabitEthernet1/0/14
  2. verify cable-diagnostics tdr interface GigabitEthernet1/0/14
  3. show cable-diagnostics tdr interface GigabitEthernet1/0/14
  4. test cable-diagnostics tdr interface GigabitEthernet1/0/14

Answer(s): D

Explanation:

"test cable-diagnostics tdr interface GigabitEthernet1/0/14" since the question asks what command will "generate" (not "display the output of") the diagnostic data needed
