An engineer must configure a Cisco router to initiate secure connections from the router to other devices in the network but kept failing .
Which two actions resolve the issue? (Choose two.)
- A . Configure a source port for the SSH connection to initiate
- B . Configure a TACACS+ server and enable it
- C . Configure transport input ssh command on the console
- D . Configure a domain name
- E . Configure a crypto key to be generated
Suggested Answer: D,E
Explanation:
Follow these guidelines when configuring the switch as an SSH server or SSH client:
+ An RSA key pair generated by a SSHv1 server can be used by an SSHv2 server, and the reverse.
+ If the SSH server is running on a stack master and the stack master fails, the new stack master uses the RSA key pair generated by the previous stack master
+ If you get CLI error messages after entering the crypto key generate rsa global configuration command, an RSA key pair has not been generated. Reconfigure the hostname and domain, and then enter the crypto key generate rsa command.
+ When generating the RSA key pair, the message No host name specified might appear. If it does, you must configure a hostname by using the hostname global configuration command.
+ When generating the RSA key pair, the message No domain specified might appear. If it does, you must configure an IP domain name by using the ip domain-nameglobal configuration command.
+ When configuring the local authentication and authorization authentication method, make sure that AAA is disabled on the
console.
