Refer to the exhibit. An engineer is troubleshooting a TACACS problem.
Which action resolves the issue?
Configure a matching TACACS server IP.
Configure a matching preshared key.
Generate authentication from a relative source interface.
Apply a configured AAA profile to the VTY.

Refer to the exhibit. NTP is configured across the network infrastructure and Cisco DNA Center. An NTP issue was reported on the Cisco DNA Center at 17:15.
Which action resolves the issue?
Reset the NTP server to resolve any synchronization issues for all devices
Check and resolve reachability between Cisco DNA Center and the NTP server
Check and resolve reachability between the WLC and the NTP server
Check and configure NTP on the WLC and synchronize with Cisco DNA Center

Refer to the exhibit. A network administrator is troubleshooting OSPF adjacency issue by going through the console logs in the router, but due to an overwhelming log messages stream, it is impossible to capture the problem.
Which two commands reduce console log messages to relevant OSPF neighbor problem details so that the issue can be resolved? (Choose two.)
debug condition ospf neighbor
debug condition interface
debug condition session-id ADJCHG
debug condition all

Refer to the exhibit. An engineer cannot copy the IOS.bin file from the FTP server to the switch.
Which action resolves the issue?
Add the IOS.bin file, which does not exist on FTP server.
Allow file permissions to download the file from the FTP server.
Make memory space on the switch flash or USB drive to download the file.
Use the copy flash:/ ftp://[email protected]/IOS.bin command.

Refer to the exhibit. An engineer receives this error message when trying to access another router in-band from the serial interface connected to the console of R1.
Which configuration is needed on R1 to resolve this issue?
R1(config)#line vty 0
R1(config-line)# transport output ssh
R1(config-line)# transport output ssh
R1(config)#line console 0
R1(config-line)# transport output ssh

Refer to the exhibit. An engineer is monitoring reachability of the configured default routes to ISP1 and ISP2. The default route from ISP1 is preferred if available.
How is this issue resolved?
Use the icmp-echo command to track both default routes.
Use the same AD for both default routes.
Start IP SLA by matching numbers for track and ip sla commands.
Start IP SLA by defining frequency and scheduling it.

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?
R1(config)#track 700 ip sla 700
R1 (config-track)#delay down 30 up 20
R1 (config-track)#delay down 30 up 20
R1 (config)#ip sla 700
R1(config-ip-sla)#delay down 30 up 20
R1(config-ip-sla)#delay down 30 up 20
R1 (config)#ip sla 700
R1(config-ip-sla)#delay down 20 up 30
R1(config-ip-sla)#delay down 20 up 30
R1(config)#track 700 ip sla 700
R1(config-track)#delay down 20 up 30

Refer to the exhibit. A user has set up an IP SLA probe to test if a non SLA host web server on IP address 10.1.1.1 accepts HTTP sessions prior to deployment. The probe is failing.
Which action should the network administrator recommend for the probe to succeed?
Re-issue the ip sla schedule command.
Add the control disable option to the tcp connect.
Modify the ip sla schedule frequency to forever.
Add icmp-echo command for the host.
