Which Systems Manager feature keeps instances in a defined configuration and re-applies it when drift is detected?
Show answer and explanation
Answer: B
State Manager applies associations that describe a desired state, such as a specific agent version, a configuration file, or a patching baseline. It evaluates targets on a schedule and re-applies the association when drift is detected. That keeps fleets consistent without relying on manual runs.
Why the other options are wrong
- A. Session Manager provides interactive shell access and does not enforce a persistent desired configuration.
- C. Inventory collects metadata about instances and installed software; it reports state but does not enforce it.
- D. Automation runs documents on demand or in response to events; maintaining steady state is the job of State Manager.
