Clickstream events arrive continuously from a busy website and must be captured and written into Amazon S3 within a minute or two of arriving, so that analysts can query them there. The team wants no cluster and no consumer application to build. Which service does this?
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
Correct Amazon Data Firehose
Correct. A delivery stream receives the records, buffers them by size or time, optionally converts or compresses them, and writes them to a destination such as S3 — with nothing for the team to run or scale.
Not correct Amazon SQS
Wrong for this. A queue decouples a producer from a consumer, but something still has to poll it, batch the messages and write the files. That consumer is precisely the application the team said it does not want to build.
Not correct AWS Glue
Wrong stage. Glue catalogs data and runs ETL jobs, usually in batches over data that has already landed. It is what you might run on the files afterwards, not what receives the stream.
Not correct Amazon Athena
Wrong. Athena queries data that is already in S3. It has no ingestion path of its own, so it can only be the step after this one.
Why
Two streaming shapes are worth telling apart. Amazon Kinesis Data Streams keeps an ordered, replayable stream that you write your own consumers against, which is what you want for real-time processing and multiple independent readers. Amazon Data Firehose — the service formerly called Kinesis Data Firehose — is the managed delivery path that simply lands the data in S3, Redshift or OpenSearch in near real time. If the requirement is 'get it into storage reliably with nothing to run', it is Firehose.

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
