- A
Passing an array is the same as passing each element individually.
Why wrong: Passing an array passes a reference; passing each element individually would create copies of element values.
- B
The method can change the size of the original array.
Why wrong: Array size is immutable once created; the method cannot change it.
- C
Modifying the array elements inside the method affects the original array.
Since the method has a reference to the same array object, changes to elements are visible to the caller.
- D
If the method assigns a new array to the parameter, the original reference is updated outside the method.
Why wrong: Assigning a new array to the parameter only changes the local copy of the reference; the caller's reference remains unchanged.
- E
The array reference is passed by value.
The reference value is copied, so the method receives a copy of the reference to the same array object.
1Z0-811 Arrays and Methods Practice Question
This 1Z0-811 practice question tests your understanding of arrays and methods. 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.
Which two statements about passing arrays to methods are correct? (Select 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
Modifying the array elements inside the method affects the original array.
Options A and B are correct. The array reference is passed by value (A), so modifications to the array elements affect the original (B). Option C is false because passing an array is not the same as passing elements individually. Option D is false because the array size is fixed. Option E is false because assigning a new array to the parameter does not affect the caller's reference.
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.
