- A
Create a Pub/Sub topic, then create a push subscription with the HTTPS endpoint URL
This is the correct order because a topic must exist before a subscription can reference it, and a push subscription requires the endpoint URL at creation time.
- B
Create a push subscription without an endpoint, then create the topic, then update the subscription with the endpoint
Why wrong: This is incorrect because a subscription cannot be created without a topic, and the push endpoint must be specified when creating the subscription; it cannot be added later via update.
- C
Configure the HTTPS endpoint to accept messages, then create the topic, then create the subscription
Why wrong: This is incorrect because while the endpoint must be ready to receive messages, the topic and subscription should be created first (or in parallel). The order of endpoint setup relative to Pub/Sub resources is not strictly required, but the typical workflow creates the Pub/Sub resources first.
- D
Create a topic, then create a pull subscription, then change it to a push subscription
Why wrong: This is incorrect because a subscription's delivery type (push or pull) cannot be changed after creation. To use push delivery, you must create a push subscription directly.
PDE Practice Question: Drag and drop the steps to set up a Pub/Sub topic…
This PDE practice question tests your understanding of pde exam topics. 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.
Drag and drop the steps to set up a Pub/Sub topic with a push subscription to an HTTPS endpoint into the correct order.

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
Create a Pub/Sub topic, then create a push subscription with the HTTPS endpoint URL
The correct order to set up a Pub/Sub topic with a push subscription to an HTTPS endpoint is to first create the topic, then create a push subscription specifying the HTTPS endpoint URL. This ensures the topic exists before the subscription references it, and the push endpoint is configured at subscription creation time. Common mistakes include creating the subscription before the topic, omitting the endpoint, or attempting to convert a pull subscription to push, which is not supported.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
