- A
Copy only the .class files of the program
Why wrong: Third-party libraries are also required; .class files alone may not suffice.
- B
Install the JDK
Why wrong: JDK is for development; JRE suffices for running.
- C
Set the PATH environment variable to include the java executable
The system must find the java command.
- D
Install the JRE
The JRE provides the runtime environment.
- E
Copy the .java source files
Why wrong: Source files are not needed for execution; compiled code is used.
Question 200 of 509
1Z0-811 What is Java Practice Question
This 1Z0-811 practice question tests your understanding of what is java. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 has written a Java program that uses third-party libraries. Which TWO actions are necessary to run the program on a different machine? (Choose two.)
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
✓
Set the PATH environment variable to include the java executable
Options C and D are correct. To run a Java program, the JRE must be installed (D) because it provides the Java Runtime Environment including the JVM. The PATH must include the java executable's directory (C) so that the 'java' command can be invoked. Option A is incorrect because .class files alone are insufficient; third-party libraries (JARs) are also needed and must be accessible. Option B is incorrect because the JDK (Java Development Kit) is only needed for compilation and development, not for running. Option E is incorrect because source files are not required to run the compiled program.
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.
