Answer Key and Explanations
Check these only after attempting every question.
1. B - settings read from the environment
A branch is right everywhere except the place somebody forgot.
2. B - before copying the source
Otherwise every source change invalidates the dependency layer.
3. B - the instance to be removed from rotation
That is what separates readiness from liveness.
4. B - the request body
It makes the log store a second copy of everything a user typed.
5. B - every in-process shared-state bug
The symptoms in production look like logic errors rather than deployment ones.
Practical Check
Apply this module to your own work: complete the module activity for *Deployment Readiness: Environment, Containers, Workers and Monitoring*, then write one sentence naming what your result shows and one naming what it does not.
Strong Answer Pattern
A strong answer names the task, the evidence used, the check performed, and the remaining limitation. It avoids "proved", "guaranteed", or "always" unless the evidence genuinely supports it.
