Question 1

A company must perform a one-time, secure migration of 300 TB of data from its on-premises data center to Amazon S3 within 7 days. The company does not have an existing AWS Direct Connect connection and cannot increase its internet bandwidth beyond 500 Mbps during the migration. The company needs the most cost-effective solution that will reliably meet the deadline. Which AWS service should the company use?

Correct Answer: AWS Snowball

AWS Snowball is designed for secure, large-scale, one-time data migrations to Amazon S3, using tamper-resistant, KMS-encrypted devices that avoid WAN bottlenecks. For hundreds of TBs, Snowball is typically the most cost-effective and time-reliable method compared to network-based transfers, especially when bandwidth is constrained. AWS Direct Connect is not suitable here because there is no existing link and provisioning a new circuit typically takes weeks and incurs significant recurring costs. AWS Storage Gateway is optimized for ongoing hybrid access and incremental transfers; over a 500 Mbps link, transferring 300 TB in a week is impractical. Amazon Connect is unrelated to data transfer.

Question 2

A company needs private, consistent network connectivity from its on-premises data center to multiple Amazon VPCs hosting game servers. They will use AWS Direct Connect and want to follow AWS best practices for high availability. They do not need access to public AWS services over Direct Connect. Which configuration is appropriate?

Correct Answer: Multiple Direct Connect connections with private virtual interfaces

Private virtual interfaces are required to provide private connectivity from on-premises to Amazon VPCs; public virtual interfaces are for accessing AWS public endpoints (such as S3) over public IPs and do not provide private VPC access. AWS best practices for high availability with Direct Connect recommend deploying multiple physical connections, ideally to separate devices and locations, to remove single points of failure. Multiple Direct Connect connections with private virtual interfaces satisfy both the need for private VPC connectivity and high availability. To reach multiple VPCs, these private VIFs can be used with a Direct Connect gateway or a Transit Gateway, but the key requirement is multiple connections with private VIFs.

Question 3

An e-commerce company recently migrated their critical applications to AWS. The application requires a maximum of 10 Gbps bandwidth to their on-premises data center. How can the company ensure consistent high bandwidth for this requirement?

Correct Answer: 3000Mbps AWS Direct Connect with AWS VPN

To meet the maximum 10 Gbps bandwidth requirement for the company's application, we can use AWS Direct Connect, which is a dedicated connection to AWS without using the public internet. We can use a 3000Mbps Direct Connect connection paired with AWS VPN to ensure consistent high bandwidth availability of 10 Gbps. The other options listed don't meet the specified bandwidth requirements.
