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?
AWS Certified Cloud Practitioner (CLF-C02), objective 3. Cloud technology and services medium
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
Choose 2.
Correct This is a hybrid deployment: part of the workload runs on premises and part runs in the cloud, and the two are integrated
Correct. Hybrid is defined by where the pieces of one workload run, and this workload deliberately keeps its latency-critical and outage-sensitive part in the building.
Correct AWS Direct Connect or an AWS Site-to-Site VPN can carry the data between the factory and AWS without it crossing the public internet in the clear
Correct. Both are built for exactly this: a VPN gives an encrypted tunnel over the internet in minutes, Direct Connect gives a private physical circuit with predictable performance.
Not correct The plant-floor application must be migrated to AWS before any analytics can run in the cloud
Wrong, and it is the assumption hybrid exists to defeat. Analytics can read data replicated or streamed from the factory while the control application stays exactly where it is.
Not correct Because part of the workload is on premises, the AWS portion cannot use managed services and must run on EC2
Wrong. There is no such restriction. The cloud side of a hybrid deployment uses whatever services suit it, managed or not; nothing about an on-premises component constrains that choice.
Not correct AWS bills the on-premises servers per hour, in the same way it bills EC2 instances
Wrong. Hardware the company owns is its own capital cost. AWS bills only for AWS resources — the exception being a service like AWS Outposts, where AWS-owned racks are installed in your building and are billed by AWS, which is not what is described here.
Why
The three deployment models are cloud (everything runs in AWS), on premises or private cloud (everything runs on your own hardware, perhaps virtualised), and hybrid (both, working together). Hybrid is normally chosen for one of three reasons: latency to something physical, a regulatory or contractual constraint on where data sits, or an existing investment that is not worth moving yet. Note the discriminator: hybrid is about WHERE the workload runs, not about how many Regions you use — a deployment spread over three AWS Regions is still an all-in cloud deployment.

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
- 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
- A training company stores its video files in an S3 bucket in one Region. Learners in Australia and Brazil report several seconds of delay before playback starts, while learners near the Region are happy. Every learner watches the same files. What is the standard fix? machine-checked
