AWS Certified Solutions Architect – Associate (SAA-C02) — Question 5

A recently acquired company is required to build its own infrastructure on AWS and migrate multiple applications to the cloud within a month. Each application has approximately 50 TB of data to be transferred. After the migration is complete, this company and its parent company will both require secure network connectivity with consistent throughput from their data centers to the applications. A solutions architect must ensure one-time data migration and ongoing network connectivity.
Which solution will meet these requirements?

Answer options

• A. AWS Direct Connect for both the initial transfer and ongoing connectivity.
• B. AWS Site-to-Site VPN for both the initial transfer and ongoing connectivity.
• C. AWS Snowball for the initial transfer and AWS Direct Connect for ongoing connectivity.
• D. AWS Snowball for the initial transfer and AWS Site-to-Site VPN for ongoing connectivity.

Correct answer: C

Explanation

The correct choice, C, uses AWS Snowball for the initial large-scale data transfer, which is efficient for moving 50 TB of data, and AWS Direct Connect for ongoing connectivity, providing a secure and reliable connection. Option A is incorrect because AWS Direct Connect alone is not suitable for the large data transfer. Option B does not address the initial transfer effectively, and option D uses a VPN, which may not provide the necessary throughput for ongoing connectivity.
