Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Application DLP

  Why it's wrong here

  Application DLP is not a recognized or standard classification within the cybersecurity industry's common taxonomy for Data Loss Prevention solutions. DLP is fundamentally concerned with data's state (at rest, in motion, in use) and its deployment location (network, endpoint, cloud), rather than being categorized by individual application integration. While applications may be sources or destinations for sensitive data, and might integrate with broader DLP systems, "Application DLP" does not represent a distinct, standalone deployment type.

• ✓

  Network DLP

  Why this is correct

  Network DLP systems are strategically positioned at key network egress points, such as internet gateways or between network segments, to inspect all data traversing the network perimeter. This deployment type actively monitors data "in motion" by analyzing network traffic, including email, web protocols, and file transfers, for sensitive content that violates predefined organizational policies. Its primary function is to prevent unauthorized data exfiltration before it leaves the controlled network environment.

• ✓

  Cloud DLP

  Why this is correct

  Cloud DLP solutions are specifically designed to protect sensitive data residing within or transiting through various cloud environments, encompassing Software-as-a-Service (SaaS) applications, Infrastructure-as-a-Service (IaaS) storage, and Platform-as-a-Service (PaaS) databases. These systems often integrate directly with cloud service providers via APIs or act as cloud access security brokers (CASBs) to monitor, classify, and protect data at rest and in use within the cloud. This ensures compliance and prevents data loss in environments outside the traditional on-premise perimeter.

• ✓

  Endpoint DLP

  Why this is correct

  Endpoint DLP agents are installed directly on individual user devices, including workstations, laptops, and mobile devices, providing granular control and monitoring capabilities at the source of data creation and access. This deployment type monitors data "at rest" on the device's storage, "in use" during operations like copy/paste or printing, and "in motion" when data is transferred via USB drives, email, or other local channels. It is crucial for preventing data loss from devices that may operate outside the corporate network.

• ✗

  Physical DLP

  Why it's wrong here

  The concept of "Physical DLP" is a misnomer and does not represent a standard or recognized category within the domain of Data Loss Prevention. DLP is a cybersecurity discipline focused on logical controls, policies, and technologies to prevent sensitive data from leaving an organization's control through digital channels. Physical security, conversely, deals with protecting tangible assets, facilities, and access points from unauthorized physical intrusion or theft, operating on an entirely different set of principles and mechanisms.
