Cloud bursting can alleviate which of the following attacks?

A Buffer Overflow is a software vulnerability where a program attempts to write data beyond the boundaries of a fixed-size buffer, which cloud bursting does not directly prevent or mitigate.

A Brute Force attack involves systematically trying every possible combination to guess credentials, which is typically mitigated by strong password policies, account lockouts, and multi-factor authentication, not by cloud bursting.

XSS (Cross-Site Scripting) is a web security vulnerability that allows attackers to inject malicious client-side scripts into web pages viewed by other users, which cloud bursting does not prevent or mitigate.

Cloud bursting involves dynamically allocating additional resources from a public cloud to handle sudden spikes in demand or workload, making it highly effective against Distributed Denial of Service (DDoS) attacks. By scaling out, the system gains additional capacity to absorb the malicious traffic, preventing the primary infrastructure from being overwhelmed and maintaining service availability.
