A company has an aging network-attached storage (NAS) array that presents SMB and NFS shares to client workstations. The company does not want to buy a new NAS or renew the support contract. Some data is frequently accessed while much is inactive. A solutions architect must migrate the data to Amazon S3, apply S3 Lifecycle policies, and keep the same client look and feel. Which AWS Storage Gateway type should the solutions architect provision?

Amazon S3 File Gateway is the correct choice because it provides a file interface (SMB and NFS) to Amazon S3, allowing existing applications and clients to continue using file protocols while data is stored as objects in S3. This meets the requirement to maintain the "same client look and feel" and allows for S3 Lifecycle policies. Volume Gateway provides block storage to applications using iSCSI, which is not suitable for migrating existing SMB/NFS shares directly. Tape Gateway is designed for archiving data to virtual tapes in S3 Glacier, not for active file sharing. Amazon FSx File Gateway is not a standard AWS Storage Gateway type; FSx for Windows File Server and FSx for Lustre are fully managed file systems, not gateways to S3 for existing shares.
