The answer is to modify the exception wrapping code to pass the original `TradeException` as a cause to the `RuntimeException` constructor. This is correct because the core issue is that the wrapper was created using the no-argument or single-string constructor, which severs the cause chain; by using `RuntimeException(Throwable cause)` or `RuntimeException(String message, Throwable cause)`, you preserve the original exception in the cause chain, allowing the logging framework to traverse and display the full stack trace. On the 1Z0-829 exam, this tests your understanding of exception chaining and the `Throwable` constructors that accept a cause parameter—a common trap is assuming that passing the original exception in the message string preserves it, which it does not. Remember the mnemonic: "To preserve the cause, pass it as a cause, not as a string."
1Z0-829 Handling Exceptions Practice Question
This 1Z0-829 practice question tests your understanding of handling exceptions. 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 financial trading application uses Java 17 and processes millions of transactions per second. It uses a custom checked exception `TradeException extends Exception` for business rule violations. Recently, the transaction processing service began throwing a `RuntimeException` that wraps a `TradeException`, but the error logs only show the wrapper's message and stack trace, missing the original `TradeException` details. The logging framework prints the exception and its cause chain. The development team needs to ensure that the original `TradeException` message and stack trace are always logged. What is the most appropriate course of action?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "always"
Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Modify the exception wrapping code to pass the original TradeException as a cause to the RuntimeException constructor.
Option C is correct because the issue is that the wrapping code does not pass the original exception as a cause. By using the `RuntimeException(Throwable cause)` constructor or `RuntimeException(String message, Throwable cause)`, the original exception is preserved in the cause chain, and the logging framework will include it. Option A is a workaround but not a proper fix and could be error-prone. Option B changes the exception type but does not address the missing cause, and may break checked exception contracts. Option D is irrelevant because the wrapper's `getMessage()` is the one being logged, not the original.
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.
✗
Catch the RuntimeException in the main processing loop and print the cause's message using getCause().getMessage().
Why it's wrong here
This workaround does not fix the root cause and may miss other places where the exception is logged.
✓
Modify the exception wrapping code to pass the original TradeException as a cause to the RuntimeException constructor.
Why this is correct
Using the cause constructor preserves the original exception in the cause chain.
Clue confirmation
The clue word "always" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
Modify the TradeException class to extend RuntimeException.
Why it's wrong here
Changing the exception type may break existing method signatures that declare checked exceptions.
✗
Override the getMessage() method in TradeException to return the original message.
Why it's wrong here
The wrapper's getMessage() is used, not the original's.
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 practitioner preparing for the 1Z0-829 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
