In a cloud-based disaster recovery (DR) strategy, what is the primary purpose of having a recovery time objective (RTO)?
To define the maximum acceptable data loss during a disruption
To specify how quickly systems can restored after a failure
To determine the geographic location of backup servers
To measure network bandwidth requirements for backups
Which disaster recovery strategy in the cloud involves maintaining a minimal version of the production environment that can be scaled up when needed?
Pilot Light
Warm Standby
Multi-site Active-Active
Backup and Restore
What is a key advantage of using cloud-based backup and restore over traditional on-premises solutions?
Higher dependency on physical media
Limited scalability
Automated offsite storage and global accessibility
Increased maintenance overhead
Which type of backup captures only the data that has changed since the last full backup?
Full backup
Incremental backup
Differential backup
Mirror backup
Which backup strategy copies only the data that has changed since the last backup of any type (full, incremental, or differential)?
Full backup
Incremental backup
Differential backup
Snapshot backup
What does the 3-2-1 backup rule recommend?
Three copies of data, stored on two types of media, with one copy offsite
Two copies of data, stored in one location, with encryption
Three cloud providers for redundancy
Daily, weekly, and monthly backups
Which cloud backup model allows organizations to back up directly from on-premises systems to cloud storage without intermediate hardware?
Direct-to-cloud
Cloud-to-cloud backup
Hybrid backup appliance
Local-only backup
When implementing a cloud disaster recovery plan, why is choosing a geographically distant backup location important?
To reduce latency during normal operations
To ensure compliance with financial regulations
To protect against regional disasters
To minimize backup costs
Which AWS service supports cross-region replication of snapshots for disaster recovery purposes?
Amazon S3
Amazon EBS with Cross-Region Snapshots
AWS Lambda
Amazon CloudFront
What is a major benefit of automating backup policies in the cloud?
Increases manual intervention for better control
Reduces human error and ensures consistency
Decreases encryption strength
Requires more frequent audits and evaluation for compliance
Which retention policy setting determines how long backup copies are kept before being deleted?
Encryption period
Backup frequency
Retention period
Compression ratio
In a warm standby disaster recovery setup in the cloud, what is typically true about the secondary environment?
It is partially running and can be quickly scaled up to full capacity.
It is fully operational and actively serving traffic at all times.
It is completely offline and requires manual setup before use.
It is used only for data backup and not for application hosting.
Which cloud backup strategy uses point-in-time copies of virtual machines or storage volumes?
File-level backup
Image-based backup
Snapshot-based backup
Database dump
What is a potential downside of relying solely on snapshots for long-term backup in the cloud?
Snapshots are not supported by any cloud provider
They consume excessive CPU during idle periods
They maybe independent of source data and can lost if the is corrupted
They cannot be encrypted
Which Microsoft Azure service provides built-in backup and disaster recovery for virtual machines and on-premises workloads?
Azure Monitor
Azure Blob Storage
Azure Backup
Azure Functions
What role does encryption play in cloud backup and disaster recovery?
It increases backup size significantly
It ensures confidentiality in transit and at rest
It eliminates the need for access controls
It reduces the need for retention policies
Which Google Cloud service enables cross-regional replication of object storage for disaster resilience?
Google Kubernetes Engine
Google Cloud SQL
Google Cloud Storage with dual-region or multi-region buckets
Google BigQuery
What is a key consideration when defining an automated backup schedule in the cloud?
Choosing the most expensive storage class available
Aligning backup frequency with Recovery Point Objective (RPO)
Avoiding encryption to speed up transfers
Running all backups during peak business hours
Which of the following best describes "cloud-to-cloud" (C2C) backup?
Backing up data from one cloud provider to another or between accounts/regions within the same provider
Transferring data from cloud VMs to on-premises tape drives
Using cloud services to host email only
Deleting old backups automatically
Why is testing disaster recovery plans in the cloud important?
It increases cloud spending unnecessarily
It ensures the plan works as expected and identifies gaps
It replaces the need for backups
It disables automation temporarily
