Answer :
Final answer:
The most effective option among those given is to install an endpoint agent to detect and control access to USB and removable media. However, this option is not actually a physical control, but rather a software one.
Explanation:
The most cost-effective physical control to enforce a USB removable media restriction policy is actually none of the options given. The reason is that physical controls, such as covering USB ports with tape or locking systems in containers, are often easy to bypass or remove. Also, they do not provide a record of unauthorized attempts to access the information.
However, from the options provided, Option D, which is about installing an endpoint agent to detect connectivity of USB and removable media, would be considered the best. This type of software can detect whenever a USB device is plugged into a system and can prevent any unauthorized devices from gaining access to information. Nonetheless, it's important to stress that this is a form of software control rather than a physical control.

Final answer:
The best example of a cost-effective physical control to enforce a USB removable media restriction policy is implementing a Group Policy Object (GPO) that restricts access to authorized USB removable media and regularly verifying its enforcement.
Explanation:
In order to enforce a USB removable media restriction policy, it is important to implement cost-effective physical controls that prevent unauthorized use of USB devices. One such example is implementing a Group Policy Object (GPO) that restricts access to authorized USB removable media and regularly verifying its enforcement.
A GPO is a feature in Windows operating systems that allows administrators to manage and enforce specific settings on multiple computers within a network. By configuring a GPO to restrict access to authorized USB removable media, organizations can ensure that only approved USB devices can be used.
Regularly verifying the enforcement of the GPO is crucial to ensure its effectiveness. This can be done by conducting periodic audits or inspections to ensure that the GPO settings are being applied correctly and that unauthorized USB devices are being blocked.
Implementing a GPO is a cost-effective solution as it utilizes existing infrastructure and does not require additional hardware or software investments. It also provides a centralized and scalable approach to enforcing USB removable media restrictions across multiple computers within an organization.
