Regionally diverse backups are backups that are stored in different geographic locations, preferably far away from the primary site1. This way, if a disaster such as a hurricane or a power outage affects one location, the backups in another location will still be available and accessible2. Regionally diverse backups can help ensure business continuity and data recovery in case of a disaster3. The other options are not the best backup solutions for a site in an area that has frequent hurricanes and an unstable power grid. High availability is a feature that allows a system to remain operational and accessible even if one or more components fail, but it does not protect against data loss or corruption4. On-site backups are backups that are stored in the same location as the primary site, which means they are vulnerable to the same disasters that can affect the primary site. Incremental backups are backups that only store the changes made since the last backup, which means they require less storage space and bandwidth, but they also depend on previous backups to restore data and may not be sufficient for disaster recovery.

Encryption is a way of protecting cardholder data by transforming it into an unreadable format that can only be decrypted with a secret key1. Backups are a way of ensuring that cardholder data is not lost or corrupted in case of a disaster or system failure2. Both encryption and backups are part of the PCI DSS requirements that apply to any entity that stores, processes, or transmits cardholder data1. The other options are not directly related to credit card data security or compliance.

A new employee will need to sign an AUP before being granted login access to the network. An AUP is an Acceptable Use Policy that defines the rules and guidelines for using network resources and services in an organization. An AUP typically covers topics such as security, privacy, ethics, compliance and liability issues related to network usage. An AUP helps protect the organization and its users from legal, regulatory and reputational risks associated with network activities. An MSDS is a Material Safety Data Sheet that provides information about hazardous substances and how to handle them safely. An MSDS is not related to network access or usage. A EULA is an End User License Agreement that specifies the terms and conditions for using a software product or service. A EULA is usually provided by software vendors or developers and does not apply to network access or usage in general. A UAC is a User Account Control that is a security feature that prompts users for permission or confirmation before performing certain actions that require elevated privileges or affect system settings. A UAC is not a document that needs to be signed by users but a mechanism that helps prevent unauthorized changes or malware infections on a system.

change management process can help ensure that owners are notified of changes being made and can monitor them for performance impact (A). This can help prevent unexpected issues from arising.

The BEST solution for preventing data theft within the call center in this scenario would be to lock the workstations after a period of inactivity. This would prevent unauthorized individuals from accessing patient data if call center agents were to step away from their workstations without logging out.
