A company needs to virtualize a replica of its internal physical network without changing the logical topology and the way that devices behave and are managed. Which of the following technologies meets this requirement?
Correct Answer:
A
Network Function Virtualization (NFV) is a technology that allows for the virtualization of a replica of a network's physical topology and the way it behaves without changing the logical topology and the way that devices are managed. NFV allows for the virtualization of network functions such as routers, firewalls, and switches, resulting in increased flexibility and scalability. This makes NFV an ideal technology for companies looking to virtualize a replica of their internal physical network.

A security analyst found the following vulnerability on the company's website:
Which of the following should be implemented to prevent this type of attack in the future?
Correct Answer:
A
Input sanitization is the process of validating and filtering the user input to prevent malicious code or commands from being executed on the web server or the web browser. Input sanitization can prevent this type of attack, which is called cross-site scripting (XSS), by removing or escaping any special characters or scripts that are not expected or allowed in the input field. Input sanitization can be implemented on the server-side or the client- side, or both, to enhance the security of the web application.
