MCQs on Backup, Recovery, and Disaster Recovery | AWS Amazon EBS MCQs
AWS Amazon Elastic Block Store (EBS) is a scalable, high-performance storage solution for EC2 instances. Chapter 5 focuses on crucial topics such as snapshot automation, cross-region backup strategies, and cross-account backups to ensure data durability, efficient recovery, and disaster recovery solutions. Learn these concepts through targeted AWS Amazon EBS MCQs.
AWS Amazon EBS MCQs – Backup, Recovery, and Disaster Recovery

b) Use S3 lifecycle policies
c) Configure CloudTrail events
d) Enable AWS Systems Manager - What happens during the first EBS snapshot creation of a volume?
a) Only incremental data is saved
b) A full copy of the volume is saved
c) Snapshot creation is not supported for encrypted volumes
d) Data is replicated to another region - How are subsequent EBS snapshots optimized for storage?
a) By saving only incremental changes since the last snapshot
b) By compressing all snapshots
c) By archiving snapshots to Glacier
d) By converting them to S3 objects - Which service can be used to create cross-account snapshot sharing policies?
a) AWS Backup
b) AWS IAM
c) AWS Resource Access Manager

a) Enables on-demand snapshot creation
b) Automates snapshot scheduling and retention policies
c) Provides real-time volume monitoring
d) Integrates snapshots with AWS Glue - When restoring an EBS volume from a snapshot, which action is required?
a) Detach and reattach the volume manually
b) Specify the original instance ID
c) Create a volume from the snapshot
d) Configure a new encryption key
Section 2: Cross-Region and Cross-Account Backup Strategies
- Cross-region snapshots in AWS are primarily used for:

c) Real-time data replication
d) Encrypting backups with customer keys - Which AWS feature allows you to copy EBS snapshots across regions?
a) Snapshot Migration Tool
b) CopySnapshot API
c) Amazon S3 Transfer Acceleration
d) AWS Global Accelerator - How can you enable cross-account snapshot sharing for an EBS snapshot?
a) Modify snapshot permissions to specify the target AWS account
b) Use AWS Direct Connect
c) Configure an Amazon S3 bucket policy
d) Share the snapshot using Elastic Load Balancer - When copying an EBS snapshot to another region, what can you modify?

a) AWS Backup
b) Amazon Athena
c) AWS Fargate
d) Amazon CloudFront - Cross-account sharing of snapshots is commonly used for:
a) Network performance optimization
b) Collaborative development across accounts
c) Creating encrypted backups
d) Isolating snapshots in an archive account - What is required to access shared snapshots in another AWS account?
a) Snapshot owner’s KMS key
b) IAM permissions for the shared account
c) A VPC endpoint configuration
d) A Direct Connect connection - Which AWS feature provides a comprehensive backup solution for EBS volumes, RDS, and other services?
a) AWS Backup
b) AWS Lambda
c) AWS Shield
d) AWS CloudFormation - What is a critical best practice for ensuring disaster recovery with EBS snapshots?
a) Use only the default region for storing snapshots
b) Regularly copy snapshots to another region
c) Avoid automating snapshot policies
d) Share snapshots only when required - When restoring a cross-region snapshot, what must you consider?
a) The storage class of the original snapshot
b) The availability zone of the target volume
c) The encryption key used for the snapshot
d) The IAM role associated with the source instance
