Patch Management

Correct Answer: Schedule a maintenance window and deploy patches during the window

The most efficient way for administrators to ensure the patches are applied correctly would be to 'Schedule a maintenance window and deploy patches during the window'. This approach allows for a controlled environment for patch deployment, ensuring minimal service interruption during non-peak operation hours. 'Apply patches immediately after they are released' is not the best approach as immediate application of patches may lead to unexpected system issues if the patches have not been thoroughly tested. 'Deploying patches manually to each server' would not be efficient especially in an environment with numerous servers. Lastly, 'Wait for users to report issues with their systems before applying patches' is reactive and not proactive. Waiting for issues to arise can lead to much larger problems and even security vulnerabilities.

Correct Answer: Implement a test environment to simulate production systems

The best approach to managing patches for a company's systems is to create and use a test environment that simulates production systems, as this offers a non-disruptive way to evaluate the impacts of a patch before it's applied to production systems. Testing patches on live production systems can disrupt operations if the patch introduces issues, and thus is not advisable. Relying solely on vendor's test results does not account for specific configurations and workflows within the individual company's systems. Having a random employee test the patch on their workstation is also not a reliable method because it does not consider the organizational scale and might have different results in a real-world scenario.

Correct Answer: Set up a patch repository or distribution point

Setting up a patch repository or distribution point is the most efficient and reliable solution for a large organization with multiple branches that needs to store and manage patches centrally. This approach allows for the automatic and controlled distribution of patches to all systems in the organization's network. Manually downloading and distributing patches to all branches is not only time-consuming and resource-intensive, but also risky as human errors may result in some systems not receiving the necessary patches. Sending patches by mail or courier is inefficient and highly vulnerable to security and logistical issues. Only applying patches to the main office system is inappropriate as it leaves the systems in the branches exposed to vulnerabilities that the patches would have resolved.
