What is the MOST cost-effective approach the administrator can take to ensure consistent transfer times from S3 to the data center?
Establish an AWS Direct Connect link to each Region. Create a private virtual interface over each link.
Establish an AWS Direct Connect link to each Region. Create a public virtual interface over each link.
Establish an AWS Direct Connect link to one of the Regions. Create a private virtual interface over that link.
Establish an AWS Direct Connect link to one of the Regions. Create a public virtual interface over that link.
Explanations:
Establishing an AWS Direct Connect link to each Region with a private virtual interface would provide redundancy and low-latency connections but is not cost-effective as it requires multiple links to be maintained, leading to higher costs.
While establishing an AWS Direct Connect link to each Region with a public virtual interface could reduce latency, it is still not cost-effective since it involves multiple links. Public virtual interfaces are primarily used for accessing AWS public services, not for direct connections to a data center.
Establishing an AWS Direct Connect link to one Region with a private virtual interface is the most cost-effective solution. This approach reduces costs by requiring only one link while providing a secure, reliable connection to transfer data from S3 to the data center, ensuring consistent transfer times.
Setting up an AWS Direct Connect link to one Region with a public virtual interface is not the best solution for transferring data securely and reliably to a data center. Public interfaces are designed for accessing AWS services over the internet, which does not guarantee consistent performance and could introduce additional costs.
