○ Functions and reusable code
○ File and directory automation
○ Exception handling
○ Subprocess and command execution
○ Logging and debugging
○ Data processing
○ Configuration and environment variables
○ Secure and maintainable automation
1. Which action is most appropriate when a script must process many text
files in a folder during a real-world situation requiring careful professional
judgment and safe procedures? The decision should be based on evidence
and the requirements applicable to the specific situation.
○ open each file manually
○ ignore file errors
● use loops, functions, file handling, and clear error handling
,○ hard-code every filename
Rationale: The correct choice follows the key requirement in this situation because it
addresses the underlying problem, reduces avoidable risk, and supports safe and
compliant professional work.
2. A professional encounters this situation: a Python program receives data
from an external command What should be done next to achieve a safe,
reliable, and compliant result? The decision should be based on evidence
and the requirements applicable to the specific situation.
○ execute every string as code
● validate and safely parse the input before using it
○ trust every value
○ skip validation
Rationale: The correct choice follows the key requirement in this situation because it
addresses the underlying problem, reduces avoidable risk, and supports safe and
compliant professional work.
3. Before the work continues, what should happen when a task repeats the
same operation for many servers according to the applicable technical,
safety, or regulatory requirements? The decision should be based on
evidence and the requirements applicable to the specific situation.
,● use reusable functions and iteration to reduce duplicated code
○ change each server manually
○ avoid variables
○ copy the same code repeatedly
Rationale: The correct choice follows the key requirement in this situation because it
addresses the underlying problem, reduces avoidable risk, and supports safe and
compliant professional work.
4. Why is the following response important when an automation script must
report failures without stopping every task while applying the relevant
principles and accepted professional practices? The decision should be
based on evidence and the requirements applicable to the specific situation.
○ use empty output
○ hide every exception
○ stop all processing immediately
● use appropriate exception handling and logging around operations that can fail
Rationale: The correct choice follows the key requirement in this situation because it
addresses the underlying problem, reduces avoidable risk, and supports safe and
compliant professional work.
, 5. During routine review, a script needs to store related key and value pairs
Which choice best addresses the underlying issue instead of only treating
the visible symptom? The decision should be based on evidence and the
requirements applicable to the specific situation.
○ use a comment
○ use a loop without storage
● use a dictionary when key-based lookup is appropriate
○ use only a string
Rationale: The correct choice follows the key requirement in this situation because it
addresses the underlying problem, reduces avoidable risk, and supports safe and
compliant professional work.
6. When a Python program must run an external command safely what is the
best next step for the responsible professional to take before making
additional changes? The decision should be based on evidence and the
requirements applicable to the specific situation.
○ use eval
● use an appropriate subprocess interface with controlled arguments
○ ignore exit status
○ build unsafe shell strings from user input
