Question
Which action can only be performed when the instance is in stopped state?
A. Running user data scripts
B. Copying user data
C. Modifying the user data
D. Viewing the Edit user data page
Answer
C. Modifying the user data
Explanation
You can view the Edit user page and copy user data when the instance is stopped or started. User data scripts never run while the instance is in a stopped state.
When managing instances, certain actions are restricted based on the state of the instance. One such action is modifying the user data. User data scripts can be used for various initialization tasks when an instance starts. However, making changes to these scripts requires the instance to be in a stopped state.
- Running User Data Scripts: User data scripts are executed automatically when an instance starts or is restarted. This action does not require the instance to be stopped. In fact, it necessitates the instance to be in a starting or running state to perform the intended tasks.
- Copying User Data: Similar to running user data scripts, copying user data does not require the instance to be stopped. This action can be performed while the instance is running or stopped, making it flexible for different operational needs.
- Modifying the User Data: To modify the user data, the instance must be in a stopped state. This restriction ensures that changes to the initialization scripts or configuration data are applied correctly without affecting the running processes. It prevents potential conflicts or inconsistencies that might arise if modifications were allowed while the instance was active.
- Viewing the Edit User Data Page: Viewing the page where user data can be edited is not restricted by the instance’s state. Users can access this page regardless of whether the instance is running, stopped, or in another state. This action simply involves viewing and does not impact the current state or performance of the instance.
In summary, the correct answer is C. Modifying the user data, as it is the only action that specifically requires the instance to be stopped to ensure safe and effective changes.
