1. What is fault tolerance?
A
The ability of a system to predict failures.
B
The ability of a system to prevent failures.
C
The ability of a system to continue operating in the event of a failure.
2. What is the purpose of fault tolerance?
A
To increase system performance.
B
To introduce intentional faults for testing.
C
To ensure system reliability and availability.
3. What is redundancy in fault tolerance?
A
Duplication of critical components to provide backup.
B
Removing components to simplify the system.
C
Increasing the complexity of the system.
4. What is a fault-tolerant system designed to do?
A
Require manual intervention for every failure.
B
Shut down immediately upon detecting a fault.
C
Continue functioning despite component failures.
5. What is the role of fault detection in fault tolerance?
A
Creating faults to test the system.
B
Identifying failures as they occur.
C
Ignoring failures to avoid system disruption.
6. What is graceful degradation in fault tolerance?
A
System's ability to degrade performance instead of failing completely.
B
System's immediate shutdown upon detecting a fault.
C
System's ability to prevent faults from occurring.
7. What is fault isolation in fault tolerance?
A
Containment of failures to prevent them from spreading.
B
Ignoring failures to focus on system performance.
C
Amplification of failures to impact the entire system.
8. What is fault recovery in fault tolerance?
A
System's inability to recover from any failure.
B
System's reliance on manual intervention for recovery.
C
System's ability to recover from failures and resume normal operation.
9. What is the goal of fault tolerance mechanisms?
A
To introduce intentional faults for fun.
B
To maximize system complexity.
C
To minimize system downtime and data loss.
10. Why is fault tolerance important in critical systems?
A
To introduce faults for entertainment purposes.
B
To ensure continuous operation and prevent catastrophic failures.
C
To increase system performance at all costs.
