CompTIA Updated SY0-701 Exam Questions and Answers by tadhg

A vulnerability scan is the most likely method to identify legacy systems. These scans assess an organization's network and systems for known vulnerabilities, including outdated or unsupported software (i.e., legacy systems) that may pose a security risk. The scan results can highlight systems that are no longer receiving updates, helping IT teams address these risks.

Bug bounty programs are used to incentivize external researchers to find security flaws, but they are less effective at identifying legacy systems.

Package monitoring tracks installed software packages for updates or issues but is not as comprehensive for identifying legacy systems.

Dynamic analysis is typically used for testing applications during runtime to find vulnerabilities, but not for identifying legacy systems​​.

Running daily vulnerability scans on all corporate endpoints is primarily done to track the status of patching installations. These scans help identify any missing security patches or vulnerabilities that could be exploited by attackers. Keeping the endpoints up-to-date with the latest patches is critical for maintaining security.

Finding shadow IT cloud deployments and monitoring hardware inventory are better achieved through other tools.

Hunting for active attackers would typically involve more real-time threat detection methods than daily vulnerability scans​​.

Detailed Explanation:Access control lists (ACLs) allow administrators to fine-tune file permissions by specifying which users or groups have access to a file and defining the level of access.
