Answer : D

The Recovery Point Objective (RPO) (D) in business continuity planning defines the maximum age of data (i.e., the amount of data loss acceptable) that can be tolerated in a disaster before recovery. It represents the time between the last backup and the point of failure, indicating potential data loss. For example, an RPO of 4 hours means up to 4 hours of data could be lost. According to ISO 22301, RPO is critical for determining backup and replication strategies.

Maximum Time Allowed (MTA) (A): Not a standard term in business continuity.

Recovery Time Objective (RTO) (B): Defines the maximum downtime before recovery, not data loss.

Maximum Allowable Outage (MAO) (C): Refers to the maximum time a system can be unavailable, similar to RTO, not data loss.

Answer : C

In corporate hiring protocols, additional screening typically refers to background checks beyond basic qualifications, such as verifying a candidate's criminal record. This is critical for IT roles, where employees may have access to sensitive systems and data, ensuring trustworthiness and compliance with security policies.

Salary demands (A) are negotiated during the hiring process, not screened. Number of years of experience (B) and educational level (D) are verified through resumes and standard checks, not typically classified as ''additional screening,'' which focuses on security-related checks like criminal records.

Answer : C

For a government system handling land title transfers, the key requirements are speed of transmission and privacy. A private blockchain is most suitable because it restricts access to authorized participants, ensuring privacy and confidentiality of sensitive data such as land ownership records. Private blockchains are controlled by a single organization or a limited group, allowing faster transaction processing compared to public blockchains, which require consensus from a large, decentralized network. This aligns with the need for quick and secure transactions in a controlled environment.

Public blockchains (B) are open to anyone, which compromises privacy for sensitive government data. Community blockchain (A) is not a standard term in blockchain technology, and consortium blockchains (D), while involving multiple organizations, are less suitable for a single government entity needing full control.

Answer : A

A use case or user story describes interactions between a user (role) and the system to achieve a specific goal, defining what the system must do. This corresponds to a functional requirement (A), which specifies the system's features or capabilities (e.g., ''the system shall allow users to submit a return request''). According to SDLC and requirements engineering, functional requirements focus on specific functionalities, as captured in use cases.

Behavioral requirement (B): Not a standard term; it may refer to system behavior but is less specific than functional requirements.

Non-functional requirement (C): Covers performance, scalability, or usability (e.g., response time), not specific user interactions.

Security requirement (D): A subset of non-functional requirements focused on security, not general use case interactions.

Answer : A

The main objective of a job rotation program in an IT organization is to support the long-term continuity of the organization (A). Job rotation ensures that multiple staff members are trained across various roles and tasks, reducing dependency on specific individuals and mitigating risks associated with staff turnover or absences. This approach enhances organizational resilience by creating a flexible, cross-trained workforce capable of maintaining operations, aligning with IT organization principles for workforce planning and business continuity.

Train staff on a range of activities (B): While training is a benefit, it is a means to achieve continuity, not the primary objective.

Increase staff job satisfaction (C): Job satisfaction may be a secondary benefit, but it's not the main goal in an IT context.

Allow staff a diversity in responsibilities (D): Diversity in tasks is a byproduct, not the primary focus, which is organizational continuity.

According to human resource management frameworks, job rotation is a strategic tool for ensuring operational stability, particularly in IT environments where specialized skills are critical.
