Exam CAS-004 topic 1 question 446 discussion

B. Have the developers use the company's VPN. A VPN (Virtual Private Network) would enable the developers to securely connect to the company's internal network as if they were within the U.S. The VPN ensures that the developers can access the website and work on it without exposing the company’s infrastructure to unwanted traffic from their country. Since the VPN would create an encrypted tunnel from the developers' location to the company’s network, they can bypass the block on foreign IP addresses. D. Give the developers access to a jump box on the network. A jump box (or jump server) is a secure machine that the developers can connect to first. From the jump box, they can access the website or the internal systems that are restricted. The jump box acts as an intermediary between the developers and the company's website, allowing controlled access while keeping unwanted traffic blocked. This can be a secure way of providing access without opening up the company’s network to the entire country.

The question states that the company "plans to" block the internet traffic from other countries. One answer should accomplish this while the other allows the developers from other countries to access the company's network and resources. B and D are redundant. Once you are connected to a company's VPN you have access to their internal resources. D would not work without B, which makes B the choice over D.

A jump box is usually INTERNAL not EXTERNAL and the IPs have already been blocked so they couldn't get in, even IF the jump box IP was external.

A. Block foreign IP addresses from accessing the website. Blocking foreign IP addresses ensures that normal internet traffic from the specified country is restricted from accessing the company's website. This helps maintain security and focus on U.S.-based customer traffic only. B. Have the developers use the company's VPN. Using a VPN allows developers from the other country to securely connect to the company's network as if they were local, bypassing the geographic IP restrictions. The VPN can be configured to allow specific IP addresses or users, ensuring that only authorized developers have access.

I agree with the solution. Proper way is to do VPN (which will allow them to reach the network even if their country IP is blocked) and then allow them secure access to a jumbox to work on the website

• Block foreign IP addresses from accessing the website: This strategy involves configuring network-level rules or firewall rules to block incoming traffic to the website from IP addresses originating from the specific foreign country. This prevents unauthorized access to the website's resources while allowing legitimate developers to access it through approved means. • Have the developers use the company's VPN: By requiring developers to connect to the company's network via a Virtual Private Network (VPN), the company can enforce secure and controlled access. The VPN connection ensures that developers' traffic is encrypted and authenticated, providing a secure tunnel through which they can access the website and other company resources.
