what will happen when an encrypted snapshots attached to a different region instances?
- Encrypted snapshots are region-specific. They cannot be attached directly to instances in another region.
- To use them cross-region, you must copy the snapshot into the target region and use an appropriate KMS key.
- Attempting a direct attachment without copying will fail due to encryption key mismatch and regional isolation of the snapshot.
This ensures that encrypted data remains secure while allowing flexibility through controlled cross-region snapshot copies.
