DVA-C02 Development with AWS Services Practice Question
This DVA-C02 practice question tests your understanding of development with aws services. 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 service publishes order events to SNS. Several consumers need different filtered subsets of events without changing publisher code. What should the developer configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SNS subscription filter policies
Option C is correct because SNS subscription filter policies allow each consumer to define a JSON policy on their subscription that selectively delivers only messages matching specified attributes (e.g., event type, region). This enables multiple consumers to receive different filtered subsets of the same SNS topic without modifying the publisher's code, as the filtering happens server-side at the SNS service level.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Separate AWS accounts for each consumer
Why it's wrong here
This does not meet the stated requirement as directly as the correct option.
✗
Lambda code that discards unwanted events after invocation
Why it's wrong here
This does not meet the stated requirement as directly as the correct option.
✓
SNS subscription filter policies
Why this is correct
Correct for the stated requirement.

This does not meet the stated requirement as directly as the correct option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse client-side filtering (Option B) with server-side filtering, or assume that SQS long polling (Option D) can filter messages, when in fact SNS subscription filter policies are the only native AWS mechanism for server-side message subsetting without publisher changes.
Detailed technical explanation
How to think about this question
SNS subscription filter policies use a JSON policy syntax that matches message attributes (e.g., { "event_type": ["order_placed", "order_shipped"] }). The filtering is applied at the SNS service before the message is delivered to the subscription endpoint (SQS, Lambda, HTTP, etc.), ensuring zero wasted downstream invocations. A subtle behavior is that filter policies are evaluated against the message attributes, not the message body, so publishers must include relevant attributes for filtering to work.

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.
