CUET PG 2026 — operating system os PYQ

CUET PG | operating system os | 2026

Assertion (A): Multi-level Queue scheduling is highly dynamic and allows processes to move between different execution queues automatically.

Reason (R): Multi-level Feedback Queue (MLFQ) scheduling accommodates processes with different CPU burst characteristics by allowing them to migrate between queues based on history.

Choose the correct answer:

Explanation

Analysis of Assertion (A): In a standard Multi-level Queue (MLQ) scheduling algorithm, processes are permanently assigned to a single queue based on their priority or type, and they do not move between queues. Therefore, Assertion (A) is false.
Analysis of Reason (R): Multi-level Feedback Queue (MLFQ) scheduling specifically allows processes to migrate between different queues based on their CPU burst history and behavior. Therefore, Reason (R) is true.

Correct Option: (d) Assertion (A) is false, but Reason (R) is true.
