Explanation:
AWS Direct Connect with a public virtual interface provides access to public AWS services like Amazon S3 across all AWS Regions globally from a single Direct Connect location. Establishing a connection to just one Region and using a public VIF is the most cost-effective way to achieve consistent transfer times to S3 buckets in multiple Regions.
Ultimate access to all questions.
A company stores data in Amazon S3 buckets that are provisioned in three separate AWS Regions. The data is copied from the S3 buckets to the data center over the public internet using a VPN. The SysOps administrator notices that, occasionally, the transfers take longer than usual, and determines the issue is congestion within the company’s ISP network. What is the MOST cost-effective approach the administrator can take to ensure consistent transfer times from S3 to the data center?
A
Establish an AWS Direct Connect link to each Region. Create a private virtual interface over each link.
B
Establish an AWS Direct Connect link to each Region. Create a public virtual interface over each link.
C
Establish an AWS Direct Connect link to one of the Regions. Create a private virtual interface over that link.
D
Establish an AWS Direct Connect link to one of the Regions. Create a public virtual interface over that link.
