A
Replication of the volume across Availability Zones
B
Replication of the volume in the same Availability Zone
C
Replication of the volume across Regions
D
Replication of the volume across Edge locations
Explanation:
When you create an EBS volume in an Availability Zone, it is automatically replicated within that zone to prevent data loss due to failure of any single hardware component. This replication happens within the same Availability Zone, not across different zones or regions. This built-in redundancy helps protect against component failures while maintaining low latency within the same AZ.
Key Points:
-
EBS volumes are automatically replicated within the same Availability Zone
-
This protects against single component failures
-
Cross-AZ or cross-region replication requires additional configuration (like EBS snapshots)
-
Edge locations are for CloudFront content delivery, not EBS storage
