The answer is that using a `try` block with one or more `except` blocks is a valid way to handle an exception in Python. This is correct because the `try` block monitors code for runtime errors, and when an exception occurs, execution immediately jumps to a matching `except` block, allowing you to catch and respond to specific error types. For the Certified Entry-Level Python Programmer PCEP exam, this tests your understanding of the core exception handling syntax, including the optional `else` clause (which runs only if no exception occurs) and the `finally` block (which always executes for cleanup). A common trap is confusing `else` with `finally`—remember that `else` skips if an exception is raised, while `finally` runs regardless. To solidify this, use the mnemonic "Try, Except, Else, Finally" in that order, and know that `except` is the only mandatory partner for `try` to handle exceptions directly.
PCEP Practice Question: Functions, Tuples, Dictionaries and Exceptions
This PCEP practice question tests your understanding of functions, tuples, dictionaries and exceptions. 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 THREE of the following are valid ways to handle an exception in Python?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Using a `try` block with both `except` and `finally` blocks.
Option A is correct because Python's exception handling allows a `try` block to be followed by both `except` and `finally` blocks. The `except` block catches specific exceptions, while the `finally` block always executes (for cleanup), regardless of whether an exception occurred. This combination is fully valid and commonly used for robust resource management.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Using a `try` block with both `except` and `finally` blocks.
Why this is correct
Combination is valid.

✗
Using a `finally` block without a `try` block.
Why it's wrong here
`finally` must be associated with a `try`.
✗
Using a `try` block with an `else` block but no `except` block.
Why it's wrong here
`else` requires an `except` block.
✓
Using a `try` block with a `finally` block.
Why this is correct
`finally` always executes.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Python Institute often tests the rule that an `else` block cannot exist without at least one `except` block, and that a `finally` block must always be attached to a `try` block, leading candidates to mistakenly think these standalone constructs are valid.
Detailed technical explanation
How to think about this question
Under the hood, Python's exception handling uses a stack of exception handlers. The `finally` block is guaranteed to execute even if the `try` block contains a `return`, `break`, or `continue` statement, making it essential for releasing external resources like file handles or network connections. A real-world scenario is closing a database connection in `finally` after a query in `try`, ensuring no resource leak even if the query fails.

→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

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
