Isaca Updated CISA Exam Questions and Answers by hughie

Granting access on a need-to-know basis ensures that a service provider only has the permissions necessary to perform their specific tasks. This principle minimizes the risk of unauthorized access or accidental misuse of the system by restricting access to essential areas only. It aligns with the least privilege principle, a cornerstone of effective access control.

Limited Administrator Access with Expiration (Option A):This is helpful but does not ensure that the access granted aligns with the specific job requirements.

Deleting User IDs After Completion (Option C):This is a good practice but applies after the task, not during access.

Access Corresponding to the SLA (Option D):While important, this focuses on timeframes and does not restrict permissions effectively.

Low-priority jobs typically involve non-critical processes or tasks that do not immediately impact business operations. The best approach to handling such jobs is to schedule them subject to resource availability. This ensures that high-priority tasks can access resources when needed without being affected by the execution of low-priority tasks.

Avoiding Low-Priority Jobs (Option A)is not feasible because even low-priority tasks may be necessary for maintenance or support activities.

Including Major Functions in Low-Priority Jobs (Option B)contradicts the classification of "low-priority" because major functions are usually critical.

Allocating Optimal Resources to Low-Priority Jobs (Option C)is inefficient as resources should primarily be allocated to high-priority tasks.

Scheduling based on resource availability optimizes the use of resources, avoids unnecessary delays in high-priority activities, and ensures that low-priority tasks are executed without disrupting overall operations. This aligns with best practices in IT resource management and scheduling.

Comprehensive and Detailed Step-by-Step Explanation:

AChange Approval Board (CAB)ensures thatall necessary testing and rollback planshave been reviewed before deployment.

Option A (Correct):ACABensures thatchanges are reviewed, tested, and approved, minimizing risks before an application is deployed. This includes confirming thatrollback plans are in place.

Option B (Incorrect):Standardized change requestsare important but donot guarantee review and approvalby management and stakeholders.

Option C (Incorrect):Third-party approvalmay be useful, but internalgovernance and control via a CABis more comprehensive.

Option D (Incorrect):Secure code reviewshelp identify vulnerabilities, but they donot confirm proper deployment and rollback procedures.
