The engineer wanted to log in to Huawei equipment remotely. When writing the SSH Python script, he used the Paramiko library to write the following code: cli.ssh.invoke_shell()…

Explanation

temporary restricts the scope of the screen-length 0 change to the current session only, rather than saving it to the device's configuration permanently - but the core purpose of screen-length 0 itself is to cancel split-screen (paged) display, which is option B. On Huawei devices, split-screen mode pauses output after each screen-full and waits for a keypress, which would cause a Python/Paramiko script to hang indefinitely waiting for input that never comes. Setting the screen length to 0 tells the device to send all output continuously without pagination, making automated scraping reliable.

Why the distractors are wrong:

• A (Cancel line wrapping) - line wrapping is controlled by a separate command (screen-width), not screen-length.
• C (Perform split-screen display) - this is the exact opposite; screen-length 0 removes paging, it doesn't enable it.
• D (Perform automatic line wrapping) - again a different feature entirely, and 0 typically means "disable," not "perform."

Memory tip: Think of screen-length 0 as "zero screens of pause" - the device will never stop and wait for you to press a key, which is exactly what you need when a script is reading the output automatically. The word temporary just reminds you it won't survive a reboot or re-login.
