Applying Hot Fixes for Production Servers

AC.

The BEST practices for applying an OS hot fix on a production server are as follows:

1. Apply the hot fix after testing in a non-production environment: (Option A) This is a critical step that should not be overlooked. Before applying the hot fix on the production server, it is essential to test it in a non-production environment to ensure that it does not cause any adverse effects. Testing in a non-production environment helps to identify and resolve any issues before they impact the production environment.

2. Apply the hot fix after following proper change management procedures: (Option C) Change management procedures are critical to ensuring that changes are made in a controlled and consistent manner. Before applying the hot fix, the server administrator should follow proper change management procedures to ensure that all stakeholders are aware of the change and that the change is approved and documented appropriately.

Therefore, the correct answers to the question are options A and C.

Option B (Apply the hot fix when it is released from the vendor) is not the BEST practice because it does not take into consideration the need for testing and proper change management procedures.

Option D (Apply the hot fix after testing in a production environment) is not the BEST practice because testing in a production environment can cause downtime and disrupt normal business operations.

Option E (Apply the hot fix once it has been superseded) is not the BEST practice because superseded hot fixes may no longer be necessary, and it is always recommended to apply the latest available hot fix for the OS.
