This PCAP practice question tests your understanding of object-oriented programming. 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.
class Counter:
count = 0
def __init__(self):
Counter.count += 1
self.id = Counter.count
c1 = Counter()
c2 = Counter()
print(c1.id, c2.id)Refer to the exhibit. What is the output?
class Counter:
count = 0
def __init__(self):
Counter.count += 1
self.id = Counter.count
c1 = Counter()
c2 = Counter()
print(c1.id, c2.id)1 1
Why wrong: Incorrect; each object gets its own id.
0 1
Why wrong: Incorrect; count increments before assignment.
1 2
Correct.
2 2
Why wrong: Incorrect; count starts at 0, increments before assignment.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
1 2
Class variable count increments each time a new object is created. First object gets id=1, second gets id=2.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
1 1
Why it's wrong here
Incorrect; each object gets its own id.
0 1
Why it's wrong here
Incorrect; count increments before assignment.
1 2
Why this is correct
Correct.

2 2
Why it's wrong here
Incorrect; count starts at 0, increments before assignment.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
