Answer the questions below
1fill in blank
easy

Complete the code to identify the deadlock prevention strategy that avoids circular wait.

Operating Systems
The deadlock prevention strategy that avoids circular wait is called [1].
Drag options to blanks, or click blank then click option'
AResource Ordering
BCircular Wait
CHold and Wait
DNo Preemption
Attempts:
3 left
💡 Hint
Common Mistakes
Confusing 'Circular Wait' as a prevention strategy instead of a condition to avoid.
Choosing 'Hold and Wait' which is actually a deadlock condition.
2fill in blank
medium

Complete the code to name the deadlock prevention strategy that avoids the no preemption condition.

Operating Systems
The deadlock prevention strategy that avoids the no preemption condition is called [1].
Drag options to blanks, or click blank then click option'
APreemption
BHold and Wait
CResource Ordering
DNo Preemption
Attempts:
3 left
💡 Hint
Common Mistakes
Choosing 'No Preemption' which actually disallows taking resources away.
Confusing 'Hold and Wait' as a prevention strategy.
3fill in blank
hard

Fix the error in the statement about deadlock prevention: "The strategy that allows processes to hold resources while waiting is called {{BLANK_1}}."

Operating Systems
The correct deadlock prevention strategy that disallows holding resources while waiting is [1].
Drag options to blanks, or click blank then click option'
ANo Preemption
BNo Hold and Wait
CPrevention
DHold and Wait
Attempts:
3 left
💡 Hint
Common Mistakes
Choosing 'Hold and Wait' which is a deadlock condition, not a prevention strategy.
Selecting 'No Preemption' which relates to resource preemption, not holding resources.
4fill in blank
hard

Fill both blanks to complete the deadlock prevention strategy that avoids circular wait.

Operating Systems
The strategy that prevents deadlock by imposing [1] on resources and eliminating [2] is effective.

Chold and wait
Dresource preemption
Attempts:
3 left
💡 Hint
Common Mistakes
Mixing up 'circular wait' with 'hold and wait'.
Choosing 'hold and wait' instead of 'circular wait' for the second blank.
5fill in blank
hard

Fill all three blanks to complete the dictionary describing deadlock prevention conditions.

Operating Systems
prevention_conditions = {"no_hold_and_wait": [1], "no_circular_wait": [2], "no_preemption": [3]
Drag options to blanks, or click blank then click option'
ATrue
BFalse
CDepends
DConditional

💡 Hint
Common Mistakes
Marking 'no_preemption' as True or False without considering system dependency.
Confusing the boolean values for the conditions.
