What additional configuration steps are required for SSH on router R1 after defining a local user account with a secret password?

• A. Enable vty access for Telnet
• B. Generate SSH keys and configure the IP domain name
• C. Set the console password and enable vty access for SSH
• D. Disable HTTP access and configure SNMP settings

Answer: (B)

The correct answer emphasizes the necessity of generating SSH keys and configuring the IP domain name as critical steps for establishing SSH connectivity on a router like R1, even after a local user account with a secret password has been defined. SSH relies on a secure key-based system to ensure encrypted communication between the client and the server. By generating SSH keys, the router is equipped to facilitate encrypted communications, thus providing the foundational security benefits that SSH offers. Without these keys, clients would have no secure method of connecting to the router, which negates the benefits of SSH. Additionally, configuring the IP domain name is essential for generating the SSH keys. SSH keys require a domain name to be set on the device, as they are tied to the cryptographic identity of the router. Thus, both generating the keys and setting the IP domain name are foundational tasks that must be completed to enable SSH successfully on the router. The focus here is on establishing the security framework needed for SSH, which cannot be overlooked.
