- A
Amazon CloudWatch Logs Insights
Why wrong: CloudWatch Logs Insights is used to query and analyze log data, not X-Ray trace data. It cannot directly search X-Ray traces by annotations.
- B
AWS X-Ray console search
The X-Ray console provides a search feature that allows you to filter traces based on annotations and other attributes. It is the most direct way to find traces with specific annotations.
- C
Amazon Athena queries on X-Ray data
Why wrong: While you can export X-Ray traces to S3 and query them with Athena, this requires additional setup and is not as immediate as the X-Ray console search.
- D
Amazon Kinesis Data Analytics
Why wrong: Kinesis Data Analytics is used for real-time analysis of streaming data and is not designed for searching static X-Ray traces.
Quick Answer
The answer is the AWS X-Ray console search. This is correct because X-Ray annotations are key-value pairs attached to trace segments that are indexed for querying, allowing developers to filter traces by specific criteria like error codes or service names. When a downstream service intermittently returns HTTP 500 errors, adding annotations such as "errorType:500" or "downstreamService:payment" enables precise searching within the X-Ray console to isolate problematic traces. On the AWS Certified Developer Associate DVA-C02 exam, this tests your understanding that annotations are searchable, while metadata is not—a common trap is confusing the two. Remember, annotations are for filtering, metadata is for reference only. For memory, think "annotations are for action" in the search bar, while metadata just sits in the segment details.
DVA-C02 Troubleshooting and Optimization Practice Question
This DVA-C02 practice question tests your understanding of troubleshooting and optimization. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 developer is using AWS X-Ray to trace a microservices application. The trace shows that a downstream service is failing with HTTP 500 errors intermittently. The developer wants to set up trace annotations to capture the error details for further analysis. Which AWS service can the developer use to search and filter traces based on these annotations?

Correct answer & explanation
AWS X-Ray console search
Option B is correct because AWS X-Ray's console search feature allows developers to query traces using annotations and metadata that are indexed by X-Ray. Annotations are key-value pairs attached to trace segments, and the X-Ray console search can filter traces based on these annotations, enabling the developer to isolate the intermittent HTTP 500 errors and analyze their details.
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 often confuse CloudWatch Logs Insights with X-Ray's native search capabilities, mistakenly thinking that log query tools can directly search X-Ray trace annotations, when in fact X-Ray provides its own indexed search for annotations and metadata.
Detailed technical explanation
How to think about this question
X-Ray annotations are indexed key-value pairs that can be used for filtering in the X-Ray console search, while metadata is not indexed and cannot be used for search. The developer must use the `putAnnotation` method in the X-Ray SDK to add annotations like `error_code` or `http_status` to segments, and then the console search supports expressions such as `annotation.error_code = "500"` to retrieve relevant traces. This is critical for debugging intermittent failures because it allows pinpointing specific error patterns without scanning all trace data.
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.
