Question

On which two occasions is it most likely that a technician will have to perform a clean operating system install if a backup has not been performed?

Answer 1

A technician will likely perform a clean operating system install if a backup has not been performed in case of severe virus/malware infection or operating system corruption/damage.

Step-by-step explanation:

A technician is most likely to perform a clean operating system install if a backup has not been performed in two situations:

1. If the computer is infected with a severe virus or malware that cannot be removed through other means. In such cases, a clean install ensures that the entire operating system is wiped clean and replaced, eliminating the malicious software.
2. If the computer's operating system becomes corrupted or damaged to the point where it is no longer functional. This could happen due to system crashes, file system errors, or other software failures.

In both situations, a clean operating system install is the only effective way to restore the computer's functionality and security.
