PCEP Practice Question: Functions, Tuples, Dictionaries and Exceptions
This PCEP practice question tests your understanding of functions, tuples, dictionaries and exceptions. 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.

Correct answer & explanation
✓
Error\nEnd
The code attempts to print 'Ok' but raises a TypeError because you cannot concatenate a string and an integer with the + operator. The exception is caught by the bare except clause, which prints 'Error', and then the finally block always executes, printing 'End'. Thus the output is 'Error' followed by 'End' on separate lines.
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
Cisco often tests the interaction between exception handling and the finally block, specifically that the finally block always executes even when an exception is caught, and that a bare except catches all exceptions, including those from type mismatches.
Detailed technical explanation
How to think about this question
In Python, the + operator for strings and integers raises a TypeError because they are incompatible types. The bare except clause catches all exceptions (including TypeError) but is generally discouraged in favor of specific exception handling. The finally block runs regardless of whether an exception occurred, making it ideal for cleanup actions like closing files or releasing resources.
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 PCEP 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.
