Final answer:
Two common remote access applications for remote maintenance and data retrieval using command line prompts are SSH and Telnet.
Step-by-step explanation:
Two common remote access applications that enable remote access into a computer system for maintenance and retrieval of data using command line prompts are **SSH** (Secure Shell) and **Telnet**.
SSH establishes a secure and encrypted connection between the client and server, allowing for secure remote access. It uses a command line interface for executing commands on the remote system.
Telnet, on the other hand, is an older protocol that transmits data in plain text, which means it is less secure. It also provides remote access using command line prompts.
