Which of the following could be part of the applicant's duties as stated in the application?

Monitoring site security as directed by their employer is a fundamental duty that aligns with the responsibilities typically expected from a qualified manager in the private security sector. This duty involves overseeing the security operations at a location, ensuring that security protocols are followed, and responding to any incidents that arise. It emphasizes the role of a qualified manager in ensuring compliance with established security policies and procedures, which is crucial for the safety and security of the site and its occupants.

In contrast, while developing new security technology and conducting independent security assessments can be important contributions within the field, they are more specialized tasks that may not necessarily be part of the standard duties outlined in an application for a management position. Training dogs for competitions is unrelated to the primary functions of a security manager within the context of a security firm and does not pertain to typical security management responsibilities. Therefore, monitoring site security effectively encapsulates the core academic focus associated with the role, making it the appropriate answer for the question.
