Introduction
The ODS Final Exam evaluates a comprehensive understanding of operating system
concepts, system architecture, resource management, security, storage, process
scheduling, synchronization, and performance optimization. Candidates are expected to
analyze complex scenarios, apply theoretical principles to practical situations, interpret
system behavior, and make sound technical decisions under realistic conditions. The
,examination emphasizes critical thinking, troubleshooting, and best practices rather than
simple memorization. This practice examination reflects current academic expectations for
the 2026/2027 study period and includes realistic multiple-choice questions designed to
strengthen conceptual understanding while preparing students for advanced university-
level or professional assessments.
Question 1
A database server experiences heavy CPU contention because hundreds of short-lived
interactive processes compete with several long-running analytics jobs. Which scheduling
algorithm best minimizes response time while preventing starvation?
A. First-Come, First-Served (FCFS)
B. Round Robin with a large time quantum
C. Multilevel Feedback Queue
D. Shortest Job First without preemption
Correct Answer: C
Explanation: Multilevel Feedback Queues prioritize interactive jobs while gradually
preventing starvation of CPU-intensive processes through dynamic priority adjustments.
,Question 2
Which memory management technique most effectively minimizes external fragmentation
while allowing non-contiguous allocation?
A. Fixed partitioning
B. Segmentation only
C. Paging
D. Contiguous dynamic allocation
Correct Answer: C
Explanation: Paging divides memory into fixed-size pages and frames, eliminating
external fragmentation.
Question 3
A deadlock exists when four necessary conditions occur simultaneously. Which condition
can be eliminated through resource preemption?
A. Mutual exclusion
B. Hold and wait
, C. Circular wait
D. Coffman condition of no preemption
Correct Answer: D
Explanation: Allowing preemption removes the no-preemption condition, preventing
deadlock formation.
Question 4
A process spends most of its execution waiting for disk operations. It is best classified as:
A. CPU-bound
B. Compute-intensive
C. I/O-bound
D. Real-time
Correct Answer: C
Explanation: I/O-bound processes spend most execution time waiting for input/output
completion.
