A router fails to initiate SSH sessions to other devices. Which two actions resolve the problem? (Choose two.)

To enable SSH on a Cisco router, two fundamental prerequisites must be met. First, a domain name must be configured using the ip domain-name command. This is essential because SSH relies on hostnames and domain names for key generation and identification. Without a domain name, the router cannot generate the necessary cryptographic keys. Second, cryptographic keys must be generated using the crypto key generate rsa command. These keys are used to encrypt the SSH session, ensuring secure communication. Without generated keys, SSH cannot establish a secure tunnel. "Configure transport input ssh on the console" is incorrect because transport input ssh is for VTY lines, not the console, and it enables SSH access to the router, not from it. "Configure a source port for the SSH connection" is incorrect as SSH clients typically use a default source port, and explicitly configuring one is not required for basic functionality. "Configure and enable a TACACS+ server" is incorrect because TACACS+ is for authentication, authorization, and accounting (AAA), which is separate from the basic functionality of initiating an SSH session.
