Answer: B

Explanation:

When setting up NetApp Cloud Volumes ONTAP to tier to Amazon S3, minimizing infrastructure costs, especially egress charges, is critical. The best way to create a connection to S3 without incurring egress charges is by using an AWS gateway endpoint.

Gateway endpoints enable a private connection between Amazon S3 and your Amazon Virtual Private Cloud (VPC), eliminating the need for internet-based routing, which would incur data transfer charges (egress fees). With this private connection, data is transferred directly between the VPC and S3 without crossing the public internet, thus avoiding egress costs.

Other options such as peering and PrivateLink are viable for connecting VPCs but do not specifically address the elimination of egress charges when connecting to S3. A NAT device is also unnecessary for this scenario and would not eliminate egress charges but could instead introduce additional costs. Therefore, the gateway endpoint is the most cost-effective and direct method for achieving the desired outcome.
