What is the recommended approach to update a VPC Service Controls perimeter without disrupting existing access?

1. Modify the perimeter immediately

2. Enable dry run mode for testing before applying changes

3. Notify all users about the impending changes

4. Request permission from all stakeholders

The correct answer is: Enable dry run mode for testing before applying changes

Enabling dry run mode for testing before applying changes is the recommended approach to update a VPC Service Controls perimeter without disrupting existing access. This mode allows administrators to simulate the changes they intend to make without actually implementing them. By using dry run mode, the potential impact of the changes can be assessed in advance, allowing for identification of any issues that might arise without affecting current operations. This approach fosters a more careful and informed decision-making process. In contrast, modifying the perimeter immediately can lead to unintended access issues or disrupt existing services, resulting in a poor experience for users. Notifying all users about impending changes is a good communication practice but does not prevent disruptions or issues that may arise from the changes themselves. Requesting permission from all stakeholders, while crucial for maintaining transparency and collaboration, may delay necessary updates and doesn’t specifically address the need to avoid disruption during the update process.
