Resolving FileNotFoundException Without Code Changes
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.
Exhibit
Exception in thread "main" java.io.FileNotFoundException: /data/config.txt (Permission denied)
at java.base/java.io.FileInputStream.open0(Native Method)

Refer to the exhibit. Which action would best resolve this error without changing the code?

A
Compile with -Xlint to get more details.
Why wrong: -Xlint adds warnings but does not fix runtime errors.
B
Change the file path to a directory that exists.
Why wrong: The file path exists; the issue is permissions, not existence.
C
Use a try-catch to handle FileNotFoundException.
Why wrong: Handling the exception does not resolve the underlying permission problem.
D
Grant read permission on the file.
The error message explicitly says 'Permission denied', so adjusting permissions fixes the issue.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Grant read permission on the file.
The error is a FileNotFoundException, which occurs when the file does not exist or cannot be opened. Since the code is correct and the file path is valid, the most likely cause is insufficient permissions. Granting read permission on the file resolves the issue without modifying the code, as it allows the JVM to access the file for reading.
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 1Z0-811 exam often tests the distinction between handling an exception (try-catch) and resolving its root cause (e.g., permissions), leading candidates to choose the try-catch option even though it does not fix the underlying issue.
Detailed technical explanation
How to think about this question
Under the hood, FileNotFoundException is a subclass of IOException thrown by FileInputStream, FileReader, and similar classes when the file is inaccessible due to missing path, wrong name, or OS-level permission restrictions. On Unix/Linux systems, the JVM relies on the OS file permission bits (e.g., chmod 644) to determine access; even if the file exists, a missing read permission for the user running the JVM will cause this exception. In real-world scenarios, this often occurs when deploying applications to servers where file permissions are restrictive by default.
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 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.
