Answer: A

Explanation:

Compartmentalizing resource access is a security technique that divides a system or network into separate segments or zones with different levels of access and control, based on the sensitivity and value of the data or resources. Compartmentalizing resource access would most effectively reduce the impact of a successful breach through a remote access solution, as it would limit the scope and extent of the breach, and prevent unauthorized access to other segments or zones that contain more critical or sensitive data or resources. The other options are not as effective as compartmentalizing resource access in reducing the impact of a successful breach through a remote access solution. Regular testing of system backups is a security technique that verifies the availability and recoverability of data in case of a system failure or disaster, but it does not prevent or limit unauthorized access to data. Monitoring and reviewing remote access logs is a security technique that records and analyzes the activities and events related to remote access sessions, but it does not prevent or limit unauthorized access to data. Regular physical and remote testing of the incident response plan is a security technique that evaluates and improves the readiness and effectiveness of an organization’s response to security incidents, but it does not prevent or limit unauthorized access to data1, p. 91-92
