100-140 Question 35
Single answerA company is rolling out a new network configuration plan to improve its security posture. As part of the implementation, you are asked to update the firewall rules to restrict access to a specific set of IP addresses and block all other traffic. What step should you prioritize to ensure the plan is implemented successfully?
- A
Verify the current firewall rules and document any changes needed.
- B
Immediately delete all existing firewall rules and create new ones based on the plan.
- C
Communicate the firewall changes to all users before implementing them.
- D
Conduct a post-implementation test after applying the new firewall rules.
Show answer and explanation
Correct answer: A
Explanation
Before implementing changes to network security configurations like firewall rules, it is critical to verify and document the current rules. This step ensures the implementation process is informed and avoids accidental disruptions or security gaps. Other actions such as communication and testing are also important but occur at different stages of the implementation process.
- A. Correct.
Correct: Verifying the current firewall rules and documenting required changes ensures you understand the existing configuration and avoid unintended disruptions during implementation.
- B. Incorrect.
Incorrect: Deleting all existing rules without verification could create security vulnerabilities or disrupt network operations.
- C. Incorrect.
Incorrect: While communicating changes is important, it is not the first step in this scenario. Priority should be given to understanding and preparing for the implementation.
- D. Incorrect.
Incorrect: Post-implementation testing is essential, but it occurs after the changes are applied. The question asks for the initial step.
