Moon Microsystems has a web-based solution that was originally built using Servlets. However, in recent months, the IS manager has asked developers to use JSP technology with Java Scriptlets embedded in HTML code. Scott Khosla, the architect, however is insisting that the code be modularized and that EJBs be used instead of Servlets and JSP for business logic processing. Asking developers to modularize existing code, what software development technique is Scott asking the developers to follow?

You are providing technical support for a supply chain product that your company (Company X) has sold to another company (Company Y). Whilst working on Company Y's site you need to run a simulation on Company X's network. This will involve securely connecting part of Company X's network to part of Company Y's network. How should you do this?

technology architecture

  1. Create a DMZ between the two networks.

  2. Create a VPN between the two networks.

  3. Create a secure network connection between the two networks by using a combination of Java sockets and JSSE.

  4. This is not possible, as the corporate firewalls would block this.

Show answer
Correct Option: B

AI Explanation

To securely connect part of Company X's network to part of Company Y's network, the recommended approach is to create a VPN (Virtual Private Network) between the two networks.

Option A) Creating a DMZ (Demilitarized Zone) between the two networks is not the best approach for securely connecting the networks. A DMZ is typically used to create a separate network segment that acts as a buffer zone between the internal network and the external network, usually for hosting public-facing services.

Option C) Creating a secure network connection between the two networks using a combination of Java sockets and JSSE (Java Secure Socket Extension) is not the most appropriate solution. While Java sockets and JSSE can provide secure communication, setting up a VPN is a more common and efficient method for securely connecting networks.

Option D) It is not accurate to say that it is not possible due to corporate firewalls blocking the connection. VPN technology is specifically designed to establish secure connections across networks, even if there are firewalls in place. Proper configuration of the firewalls can allow VPN traffic to pass through.

Therefore, the correct answer is B) Create a VPN between the two networks. This option provides a secure and encrypted connection between Company X's and Company Y's networks, allowing for the simulation to be run securely.
