Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a real-time system where Task A (high priority) is waiting for Resource X held by Task B (low priority). Task C (medium priority) arrives and preempts Task B. Describe how PIP would resolve this priority inversion.

💡 Hint: Consider how prioritization changes affect the flow of task execution.

Challenge 2 Hard

Illustrate a potential scenario where chained blocking occurs due to priority inversion. What can be done in system design to prevent this issue?

💡 Hint: Think about how resource management affects priority scheduling.
