Which of the following WiFi security options would create the MOST need for a VPN connection on the client
device?
Open is a WiFi security option that does not use any encryption or authentication to protect the wireless network from unauthorized access or eavesdropping. Open would create the most need for a VPN connection on the client device because VPN (Virtual Private Network) is a technology that creates a secure and encrypted tunnel between the client device and a remote server over the Internet. VPN would provide an additional layer of security and privacy for the wireless communication that is not provided by the open WiFi network. WEP (Wired Equivalent Privacy), WPA (WiFi Protected Access), and WPA2 (WiFi Protected Access II) are WiFi security options that use encryption and authentication to protect the wireless network from unauthorized access or eavesdropping. WEP, WPA, and WPA2 would create less need for a VPN connection on the client device than open because they already provide some level of security and privacy for the wireless communication.Reference: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 311.

An employee is asked to generate a report on a student information system. The employee uses spreadsheet software and connects to a remote database to pull data for the report. Which of the following types of
application architectures did the employee use?
A client-server application is an application that runs on a client device and communicates with a server device over a network. The client device requests data or services from the server device, and the server device responds to the requests. A spreadsheet software that connects to a remote database is an example of a client-server application. The spreadsheet software acts as the client, and the database acts as the server.Reference: The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 128.
