Amazon FSx for NetApp ONTAP fully supports native NetApp SnapMirror replication, making it the most efficient and reliable option for migrating NetApp data from on-premises to AWS.

From AWS Documentation:

“You can use SnapMirror to replicate data from your on-premises NetApp systems to FSx for ONTAP for seamless, block-level, incremental transfers. This provides a highly efficient and performant method for migration, especially for large datasets.”

(Source: Amazon FSx for NetApp ONTAP – Migration Guide)

Why Option C is correct:

SnapMirror offers block-level replication, making it highly efficient for millions of small files.

It supports NFS and SMB file shares, preserving directory structures and permissions.

Reduces cutover time and allows for incremental syncs.

Uses the existing 10 Gbps network for fast transfers.

Why the other options are incorrect:

Option A (DataSync): Suitable for many file-based migrations but less efficient for very large datasets with millions of small files compared to SnapMirror.

Option B (Storage Gateway): Volume Gateway is not used for full-scale file migrations; it ' s for hybrid cloud access.

Option D (Snowball Edge): Useful for offline migrations, but online SnapMirror is more efficient and avoids shipping delays.

AWS DataSync provides a fully managed, secure, and high-performance service for transferring large amounts of data between on-premises storage and Amazon S3. It uses TLS encryption in transit and automates data validation, scheduling, and monitoring.

From AWS Documentation:

“AWS DataSync securely and efficiently transfers large amounts of data online between on-premises storage and AWS services. All data is encrypted in transit using TLS.”

(Source: AWS DataSync User Guide – How DataSync Works)

Why B is correct:

Encrypts all data in transit automatically.

Optimized for high-throughput WAN environments (100 Mbps to multi-Gbps).

Fully managed, with no need to provision additional infrastructure.

Integrates natively with S3 and supports incremental syncs.

Why others are incorrect:

A: DMS is designed for database migration, not unstructured data.

C: Snowball is for offline migrations, not needed given available connectivity.

D: Direct Connect is costly for temporary data transfers and unnecessary here.

Amazon S3 Intelligent-Tiering automatically moves objects between frequent and infrequent access tiers based on access patterns, which minimizes cost without performance impact. Storing photo metadata in Amazon DynamoDB provides fast and scalable lookup by user or tag.

From AWS Documentation:

“The S3 Intelligent-Tiering storage class automatically optimizes storage costs by moving data between frequent and infrequent access tiers when access patterns change.”

(Source: Amazon S3 User Guide – Intelligent-Tiering)

Why B is correct:

S3 Intelligent-Tiering optimizes storage automatically for cost without lifecycle management overhead.

DynamoDB stores small metadata items and S3 URLs, enabling efficient queries and photo lookups.

This architecture scales globally, integrates seamlessly with applications, and minimizes operational cost.

Why other options are incorrect:

A & D: DynamoDB is not intended for storing binary objects like images.

C: Lifecycle rules are static and don’t adapt dynamically to unpredictable access patterns.
