- A
Cloud Tasks with a daily task enqueued by a Cloud Function
Why wrong: Cloud Tasks handles task queuing and delivery but requires something to enqueue the task on schedule — more complex than Cloud Scheduler for a simple timed HTTP call.
- B
Cloud Scheduler with an HTTP target pointing to the backup endpoint
Cloud Scheduler sends a configured HTTP request to the backup endpoint at 2 AM UTC daily — the exact use case it's designed for, requiring minimal setup.
- C
Cloud Composer DAG running at 2 AM UTC
Why wrong: Cloud Composer (managed Airflow) is designed for complex multi-step data pipelines — it's overengineered for a single scheduled HTTP call.
- D
Cloud Run Jobs triggered by a Cloud Monitoring alert at 2 AM
Why wrong: Cloud Monitoring alerts respond to metric thresholds, not time-based schedules — Cloud Scheduler is the right tool for time-based job triggering.
Quick Answer
The answer is Cloud Scheduler with an HTTP target pointing to the backup endpoint. This is the simplest choice because Cloud Scheduler is a fully managed cron service that natively supports HTTP targets, meaning you can directly schedule a daily HTTP backup job without writing any code or setting up a queue or orchestration layer. On the Google Associate Cloud Engineer exam, this scenario tests your understanding of when to use a lightweight scheduling service versus more complex options like Cloud Tasks or Workflows, which are overkill for a simple timed HTTP call. A common trap is overcomplicating the solution by adding Pub/Sub or Cloud Functions when the requirement is just a recurring HTTP trigger. Remember the memory tip: if the job is “just a call, not a queue or a workflow,” Cloud Scheduler is the tool for you.
Google ACE Practice Question: Ensuring successful operation of a cloud solution
This ACE practice question tests your understanding of ensuring successful operation of a cloud solution. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A team needs a database backup job to run every day at 2 AM UTC. The job calls an HTTP endpoint to trigger the backup. The endpoint requires no complex orchestration — just a timed HTTP call. Which GCP service handles this most simply?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cloud Scheduler with an HTTP target pointing to the backup endpoint
Cloud Scheduler is the simplest GCP service for a recurring HTTP call because it is a fully managed cron job service that directly supports HTTP targets. You configure a schedule (e.g., '0 2 * * *' for daily at 2 AM UTC) and point it to the backup endpoint URL. No additional code, queue, or orchestration is needed, making it the most straightforward solution for this use case.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates overcomplicate the solution by choosing Cloud Tasks (A) or Cloud Composer (C) because they assume a 'job' requires a queue or orchestration, when Cloud Scheduler's HTTP target is the simplest and most direct fit for a single timed HTTP call.
Detailed technical explanation
How to think about this question
Cloud Scheduler uses the same cron format as Unix (e.g., '0 2 * * *') and supports HTTP targets with optional OIDC or OAuth2 authentication for secure endpoint invocation. Under the hood, it leverages Google's internal cron infrastructure, ensuring high availability and at-least-once delivery semantics, with a 10-second default timeout that can be extended up to 30 minutes for longer-running HTTP calls. A real-world scenario where this matters is triggering a Cloud Function or Cloud Run service for a nightly backup, where the simplicity of a single scheduler job avoids the latency and cost of a queue-based approach.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
