Answer: AWS Snowball Edge Storage Optimized

## Explanation **Correct Answer: C. AWS Snowball Edge Storage Optimized** ### Why AWS Snowball Edge Storage Optimized is the best choice: 1. **Data Volume (50 TB)**: 50 TB is a significant amount of data to transfer over network connections. 2. **Time Constraint (2 weeks)**: Transferring 50 TB over the internet would take too long, especially with a 90% utilized VPN connection. 3. **Network Constraints**: The existing Site-to-Site VPN is already 90% utilized, meaning there's insufficient bandwidth for such a large data transfer. 4. **Security Requirements**: Snowball provides secure, encrypted data transfer with tamper-evident enclosures. ### Why other options are not optimal: **A. AWS DataSync with a VPC endpoint**: - DataSync is designed for ongoing data synchronization, not one-time bulk transfers - Still relies on network bandwidth which is insufficient (90% utilized VPN) - 50 TB over limited bandwidth would exceed the 2-week timeframe **B. AWS Direct Connect**: - While Direct Connect provides dedicated network connection, it takes weeks to months to provision - Doesn't solve the immediate 2-week timeframe requirement - Still requires transferring 50 TB over network which would be slow **D. AWS Storage Gateway**: - Designed for hybrid storage solutions with on-premises applications - Not optimized for one-time bulk data migration - Would still use the congested VPN connection ### Key Benefits of AWS Snowball Edge Storage Optimized: - **Physical data transfer**: AWS ships a physical device to your location - **Fast transfer**: Transfer data locally at high speeds (up to 100 Gbps) - **Secure**: Tamper-evident enclosure, 256-bit encryption - **Time-efficient**: Can transfer 50 TB in days rather than weeks over internet - **Cost-effective**: No egress charges for data transfer ### Calculation for context: - 50 TB = 50,000 GB = 400,000 Gb - With a 100 Mbps connection (typical VPN): ~46 days - With a 1 Gbps connection: ~4.6 days - With Snowball Edge: Local transfer at 40+ Gbps, then physical shipping This makes AWS Snowball Edge Storage Optimized the most practical solution for securely transferring 50 TB of data within 2 weeks given the network constraints.
