3.8 Identify services from other in-scope AWS service categories.
Objective 3.8 sits in Cloud Technology and Services, which carries 34% of the Cloud Practitioner exam. The questions below are original, written from the official objective title above, and each explanation cites the Amazon Web Services (AWS) page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A checkout service creates orders faster than the fulfilment worker can handle them, and work is being dropped at peak. Which service absorbs the backlog?
Correct.
Concept
Two components that call each other directly must run at the same speed. Putting durable storage between them lets the producer finish while the consumer works through the backlog at its own rate.
Why A
A hosted queue holds each message durably until a consumer takes it, which decouples the two components. The fulfilment worker then drains the backlog after the peak instead of losing requests during it.

Sample question 1 of 3
A team needs one order event to reach an email address, a Lambda function and an SQS queue at the same time. Which service does that?
Sample question 2 of 3
A team must run six Lambda functions in a defined order, retry failures, and see where an execution stopped. Which service coordinates that?
Sample question 3 of 3
A payment pipeline cannot tolerate the same message being processed twice. Which Amazon SQS queue type fits?
That’s 3 of the full Cloud Practitioner bank.
