- Hotfix
- Service pack
- Feature update
- Patch
A hotfix is a type of update that addresses critical security vulnerabilities and is released urgently.
17. In a patch management policy, what is the role of a maintenance window?
- A designated period for skipping updates
- A timeframe for scheduling updates without user impact
- A delay in applying updates indefinitely
- A schedule for applying updates without testing
A maintenance window is a timeframe for scheduling updates without user impact.
18. Which statement best describes the concept of "regular patching"?
- Applying updates only once a year
- Applying updates at random intervals
