CompTIA FC0-U61 Dumps Questions Answers

A database is a collection of data that is organized and stored in a way that allows easy access, manipulation, and analysis. A database would be the best option for storing information for an application that needs to be accessed by concurrent users and store company information securely. A database can handle multiple user requests, enforce data integrity and security, and perform complex queries and operations on the data. A word processing document, a flat file, and a spreadsheet are not options that can support concurrent users, store company information securely, or perform complex operations on the data. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 5: Database Fundamentals, page 191.

A wireless access point (WAP) is a device that allows wireless devices to connect to a wired network using Wi-Fi or Bluetooth. A WAP usually has a default configuration that is set by the manufacturer, which may include a default password, SSID (service set identifier), encryption type, and wireless standard. The default password is often weak or well-known, which makes the WAP vulnerable to unauthorized access or hacking. Therefore, the first thing that a user should do when setting up a new WAP is to change the default password to a strong and unique one. This will help secure the WAP and prevent unwanted changes or attacks. Changing the SSID to a unique name, enabling WPA2 encryption, and enabling the highest available wireless standard are also important steps to improve the security and performance of the WAP, but they should be done after changing the default password.

 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. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 311.
