A system maintenance and testing program of physical protection systems should establish which two types?

This option suggests a focus on remedial measures performed quarterly, which may not adequately address ongoing system needs. While remedial actions are essential, they should be combined with preventative strategies to create a robust maintenance program that minimizes potential failures and enhances overall system reliability.

Although preventative maintenance is a crucial component, conducting it only on an annual basis may not be sufficient for effective system management. Regularly scheduled preventative measures should ideally be more frequent to promptly address wear and tear, thereby sustaining the system's effectiveness throughout the year.

While quarterly preventative maintenance is beneficial, it does not encompass the remedial aspect necessary for a complete maintenance program. Preventative measures alone cannot rectify issues that have already occurred, making it essential to integrate both remedial and preventative types for comprehensive system protection.
