Sara, an application developer, implemented error and exception handling alongside input
validation. Which of the following does this help prevent?

A.
Buffer overflow

B.
Pop-up blockers

C.
Cross-site scripting

D.
Fuzzing

Explanation:
Buffer overflow is an exploit at programming error, bugs and flaws. It occurs when an application is
fed more input data than it is programmed to handle. This may cause the application to terminate
or to write data beyond the end of the allocated space in memory. The termination of the
application may cause the system to send the data with temporary access to privileged levels in
the system, while overwriting can cause important data to be lost. Proper error and exception
handling and input validation will help prevent Buffer overflow exploits.
