CV0-004 Practice Question: A developer deployed a new version of a cloud…
A developer deployed a new version of a cloud function, but the function is returning 500 errors. The previous version worked fine. What is the most likely cause?
⚠ Common exam trap
CompTIA often tests the distinction between code-level errors (500) and resource/configuration errors (memory, timeout, runtime), tempting candidates to blame environment settings when the actual cause is a bug introduced in the new code.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The new code contains a runtime error.
The most likely cause of 500 errors after deploying a new version of a cloud function is a runtime error in the new code. A 500 Internal Server Error indicates that the function's code executed but threw an unhandled exception or logic error, which did not exist in the previous working version. Since the environment (runtime, memory, timeout) remained unchanged, the introduction of faulty code is the primary suspect.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The function is using an outdated runtime.
Why it's wrong here
The runtime was likely the same for both versions; an outdated runtime would affect both.
- ✓
The new code contains a runtime error.
Why this is correct
A bug in the new code is the most common cause of 500 errors after deployment.
- ✗
The function's memory allocation is too low.
Why it's wrong here
Memory issues would likely affect all versions equally or cause timeouts, not specifically new code.
- ✗
The function's timeout is set too short.
Why it's wrong here
Timeout errors would produce a different error message, not 500.
