A film studio's editors work on terabytes of footage from workstations in the building and need local disk speed while editing. The company wants the bulk of the archive to live in Amazon S3 and the on-premises storage array to shrink. Editing directly over the wide-area link has already been tested and is too slow. What fits?

Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
The options
Correct AWS Storage Gateway
Correct. It is an on-premises appliance that presents a familiar file, volume or tape interface locally, caches the recently used data on local disk for speed, and stores the full dataset in AWS.
Not correct A nightly script that copies finished projects to S3 with the AWS CLI
Wrong. That is a backup, not a storage tier. The local array still has to be sized for the entire archive, and getting an old project back is a manual restore rather than opening a file.
Not correct Amazon FSx for Lustre
Wrong for this shape. It is a high-performance file system that runs in AWS, close to compute, and it does link to S3 — but it puts nothing in the studio's building, so the editors are still working over the slow link.
Not correct AWS Snowball
Wrong. Snowball physically moves a large dataset once, when the network cannot. It is a migration device, not an ongoing hybrid storage path.
Why
Storage Gateway is the 'keep the on-premises interface, put the capacity in AWS' service, and its three modes map to three existing habits: File Gateway presents NFS or SMB shares whose files become S3 objects, Volume Gateway presents iSCSI block volumes backed by AWS with snapshots, and Tape Gateway presents a virtual tape library so existing backup software keeps working unchanged. All three cache hot data locally, which is what preserves local speed.

More questions on this objective
- A team builds the same stack — a load balancer, three EC2 instances and a database — by clicking through the console once for dev, once for test and once for production. The three environments have quietly drifted apart and a bug that only appears in production took a week to trace to a missing setting. They want the stack described once, reviewed in a pull request, and applied identically to each environment. Which service does that? machine-checked
- A Python reporting job runs unattended every night. Inside its own logic it needs to list objects in an S3 bucket, read a few of them, and write a summary object back, handling failures with the program's existing retry and logging code. What is the appropriate way for that program to call AWS? machine-checked
- A small team has a Java web application and no operations staff. They want to hand AWS the application package and have it provision the instances, the load balancer and the scaling policy, while keeping the ability to inspect and adjust those resources later if they need to. Which service fits? machine-checked
- A manufacturer keeps its plant-floor control application on servers inside the factory, because production must continue when the internet link drops. Its reporting and analytics run in AWS and read the same production data. Which TWO statements about this arrangement are accurate? machine-checked
- An internal application runs on a single EC2 instance in one Availability Zone. During a power event in that Availability Zone the application was unreachable for four hours. The team wants the cheapest change that keeps it serving through the same kind of event, without moving to another Region. What should they do? machine-checked
- A German insurer is told by its regulator that customer records must remain within the European Union. Four candidate Regions can all run every service the workload needs, and one of them is noticeably cheaper per instance-hour. Which consideration settles the choice of Region first? machine-checked
