Cloud Backup & Disaster Recovery Fundamentals

1. Which encryption method protects data both in transit and at rest?

Only TLS encryption

AES encryption for storage and TLS for transmission

No encryption is needed in cloud backup

Only symmetric encryption

2. True or False: A lower RPO means less tolerance for data loss.

True

False

3. True or False: Cloud backups eliminate the need for on-premises backup copies.

True

False

Submit

6. Which compliance standard requires regular backup testing for financial institutions?

SOX (Sarbanes-Oxley) and HIPAA

Only GDPR

No standards exist

Only internal company policies

7. In disaster recovery, what is a failover?

Automatic switching to a backup system when the primary fails

Deletion of corrupted data

Compression of backup files

Testing the backup system

8. What does 'cold storage' refer to in cloud backup?

Infrequently accessed data stored at lower cost with longer retrieval times

Data that must be kept at low temperatures

Encrypted backup data

Real-time synchronized data

9. Which cloud provider feature allows automatic failover to another region?

Load balancing and multi-region replication

Data compression

User access controls

Network latency optimization

10. What is a Recovery Time Objective (RTO) of 2 hours?

Systems must be restored within 2 hours after a disaster

Data loss cannot exceed 2 hours of transactions

Backups must run every 2 hours

The cloud provider guarantees 2 hours of uptime

11. What is the primary goal of a backup strategy in cloud computing?

To create copies of data for recovery in case of loss or corruption

To increase cloud storage capacity

To improve network speed

To reduce cloud service costs

12. In cloud environments, what is data replication?

Copying data to multiple locations for redundancy and availability

Deleting old backup files

Encrypting data during transmission

Compressing files to save space

13. What is the difference between disaster recovery and business continuity?

Disaster recovery focuses on data recovery; business continuity focuses on maintaining operations

They are identical concepts

Business continuity is only for large enterprises

Disaster recovery is faster than business continuity

14. Which of the following is NOT a common cloud backup storage location?

Object storage buckets

Local hard drives only

Cloud data centers

Geographically distributed regions

15. What is the 3-2-1 backup rule?

3 copies of data, 2 different media types, 1 offsite

3 servers, 2 networks, 1 cloud provider

3 daily, 2 weekly, 1 monthly backup

3 hours RPO, 2 hours RTO, 1 backup site

16. Which cloud service model includes Infrastructure as a Service (IaaS)?

Virtual machines, storage, and networking provided by the vendor

Pre-built applications accessible via web browser

Development platforms and databases only

Email and collaboration tools exclusively

17. In cloud computing, what is a snapshot?

A photograph of network traffic

A point-in-time copy of a virtual machine or storage volume

A temporary cache of data

A scheduled maintenance window

18. Which backup method copies only data that has changed since the last backup?

Full backup

Incremental backup

Snapshot backup

Differential backup

19. What does RTO stand for in disaster recovery planning?

Recovery Time Objective

Redundant Transfer Operation

Remote Technology Optimization

Replication Threshold Overage

20. Which of the following best describes Recovery Point Objective (RPO)?

The maximum acceptable data loss measured in time

The total time needed to restore all systems

The number of backup copies to maintain

The bandwidth required for backup operations
