Which method is used to access the CLI over a serial connection?

• A. SSH
• B. WebView
• C. Console Application
• D. HTTPS

Answer: (C)

Accessing the CLI over a serial connection is done with a console (terminal) application. This type of program opens a serial port on your computer and communicates with the device’s console, sending keystrokes and displaying the device’s text output in real time. You typically set the port parameters (baud rate, data bits, parity, stop bits) to match the device so the data is interpreted correctly. This direct, text-based link is the standard way to interact with the device’s CLI when you’re physically connected.

Network-based methods like SSH or HTTPS require network services on the device and an IP path to reach them, so they don’t operate over a raw serial cable. WebView is for displaying web content, not for a serial CLI session. Hence, the console/application approach is the right one for serial access.
