CompTIA Network+ N10-009 (V9) Practice Question

A vulnerability refers to a weakness in a system that can be exploited to compromise the security of the network or system. Understanding vulnerabilities helps in prioritizing security efforts and mitigating risks. 'Exploit' is an incorrect answer because it refers to the method by which someone takes advantage of a vulnerability. 'Risk' refers to the potential for loss or damage when a threat exploits a vulnerability, making it also incorrect. 'Threat' is a potential cause of an unwanted impact to a system or organization, thus also incorrect.
