Cloud+ V3 Redundancy and Fault Tolerance Design Quiz

1. Which of the following is a characteristic of a cold standby disaster recovery site?

Fully operational and ready for immediate failover

Partially replicated with periodic synchronization

Dormant with no active systems or data sync

Identical to production with real-time replication

2. What is the relationship between availability zones and fault tolerance in cloud design?

Availability zones have no impact on fault tolerance

Distributing resources across zones provides geographic redundancy

All zones share the same infrastructure

Zones only affect network latency

Submit

4. In a multi-region cloud deployment, what does data consistency across regions depend on?

Network bandwidth only

The replication strategy and acceptable RPO/RTO

The number of users

The type of cloud provider

5. Which cloud service model typically provides built-in redundancy and fault tolerance?

Infrastructure as a Service (IaaS)

Platform as a Service (PaaS)

Software as a Service (SaaS)

All of the above equally

Submit

7. What is the primary benefit of implementing auto-scaling in cloud systems?

It eliminates the need for monitoring

It maintains performance during traffic spikes and reduces costs during low demand

It removes the need for redundancy

It simplifies network architecture

8. Which architecture pattern distributes application logic across multiple availability zones?

Monolithic architecture

Multi-tier architecture

Distributed architecture

Serverless architecture

Submit

10. What is the main purpose of implementing health checks in a cloud load balancer?

To monitor employee performance

To detect failed instances and route traffic away from them

To encrypt all data transmissions

To reduce database connections

11. What is the primary purpose of implementing redundancy in cloud architecture?

To reduce operational costs

To eliminate single points of failure and ensure service continuity

To simplify system management

To increase network bandwidth

Submit

13. In cloud architecture, what does 'failover' refer to?

The process of scaling down resources

Automatic switching to a backup system when primary fails

The failure of a single database node

Reducing redundancy to cut costs

14. What is the primary advantage of using a Content Delivery Network (CDN) for fault tolerance?

It eliminates the need for backups

It reduces latency and provides geographic redundancy

It encrypts all data in transit

It reduces database query complexity

15. Which cloud redundancy pattern requires all nodes to process the same requests simultaneously?

Active-passive

Active-active

Cold standby

Warm standby

Submit

17. A load balancer distributes traffic across multiple servers. What is this an example of?

Database replication

Horizontal scaling with redundancy

Vertical scaling

Data encryption

18. What does RTO (Recovery Time Objective) measure in disaster recovery planning?

The maximum acceptable data loss

The maximum tolerable downtime

The cost of recovery operations

The number of backup copies needed

19. In an active-passive failover configuration, what is the role of the passive node?

To handle all incoming traffic

To remain idle until the active node fails

To balance load equally with the active node

To serve as a backup database only

20. Which fault tolerance strategy involves maintaining synchronized copies of data across multiple geographic regions?

Active-active replication

Geo-redundancy

Load balancing

Caching strategy
