Multilevel Queue Scheduling Quiz

In a multilevel queue scheduling system, how are processes assigned to queues?

• Based on process ID

• Based on process priority and type

• Randomly assigned by the scheduler

• Based on execution time

In multilevel queue scheduling, which type of queue typically has the highest priority?

• Interactive processes

• Background processes

• System processes

• Batch processes

What is a key disadvantage of multilevel queue scheduling?

• It cannot handle foreground processes

• Starvation can occur for lower-priority queues

• It does not support process execution order

• It does not allow priority scheduling

In multilevel feedback queue scheduling, how do processes move between queues?

• Based on CPU burst time and aging

• Based on manual user input

• Randomly

• They cannot move between queues

What is the primary advantage of multilevel feedback queue scheduling?

• It requires no intervention from the scheduler

• It allows dynamic adjustment of process priority

• It executes all processes at the same speed

• It prevents starvation for high-priority processes

Which of the following is a key difference between multilevel queue scheduling and multilevel feedback queue scheduling?

• Multilevel queue allows process movement between queues

• Multilevel feedback queue allows process movement between queues

• Multilevel feedback queue does not use multiple queues

• Multilevel queue does not allow CPU allocation

What is the main goal of multiprocessor scheduling?

• Assign processes efficiently across multiple CPUs

• Ensure that only one CPU is used at a time

• Reduce the number of processors needed

• Eliminate process synchronization

Which of the following is a key challenge in multiprocessor scheduling?

• Single-threaded execution

• Load balancing across processors

• Only batch processing is allowed

• The system can use only one queue

In symmetric multiprocessing (SMP), how are processes scheduled?

• Only the master processor schedules tasks

• Each processor runs its own scheduler

• Scheduling is handled by an external system

• The OS does not control scheduling

What is the main advantage of symmetric multiprocessing (SMP)?

• No need for an OS scheduler

• Efficient load distribution and fault tolerance

• Only one processor is used at a time

• Processes must always execute in sequence
