- A
Close both resources in a finally block using separate try-catch for each close.
Why wrong: This is verbose and error-prone; if resource creation fails, variables may be null leading to NullPointerException.
- B
Use try-with-resources with both resources declared in the try header.
try-with-resources ensures that each resource is closed automatically, in reverse order, even if an exception occurs.
- C
Close only the BufferedReader in a finally block.
Why wrong: Closing only the outer resource may not close the underlying FileReader, causing a resource leak.
- D
Throw a custom exception after closing resources in the catch block.
Why wrong: If an exception occurs before close statements, resources remain open; also, throwing after close bypasses cleanup if an earlier exception occurred.
1Z0-811 Exception Handling and Development Tools Practice Question
This 1Z0-811 practice question tests your understanding of exception handling and development tools. 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 writes a method that reads a file and processes its contents. The method uses a BufferedReader wrapped around a FileReader. Which of the following approaches ensures that both resources are properly closed even if an exception occurs?
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
Use try-with-resources with both resources declared in the try header.
Option B is correct because try-with-resources automatically closes resources declared in the try header in reverse order. Option A is wrong because closing only the outer resource may not close the inner one if wrapped incorrectly. Option C is wrong because closing in the finally block without checking for null can cause NullPointerException if resource creation fails. Option D is wrong because throwing an exception before close statements prevents cleanup.
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 practitioner preparing for the 1Z0-811 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.
