DLP (Data Loss Prevention) is a service that prevents the unauthorized or accidental disclosure of confidential or sensitive data, such as company information, intellectual property, customer data, or personal information. DLP can monitor, detect, and block the data in motion (such as email, web, or network traffic), data at rest (such as files, databases, or cloud storage), or data in use (such as endpoints, applications, or clipboard). DLP can help a systems administrator to ensure confidential company information is not leaked to competitors by applying policies and rules that define what data is considered confidential, who can access it, how it can be used, and what actions to take if a violation occurs. For example, DLP can encrypt, quarantine, delete, or alert the administrator if confidential data is being copied, transferred, or shared outside the organization.

If a whole rack of servers was inaccessible during a power outage, even though the servers did not lose power, it is likely that the switch that connects them to the network lost power. Without network connectivity, the servers would not be able to communicate with other devices or services. The administrator should investigate the switch power source and ensure it has a backup power supply or UPS.
