What is WPA2 also known as? WiFi Privileged access 802.11x 802.8i

802.11x WPA2-Enterprise with 802.1X Authentication 802.1X is an IEEE standard framework for encrypting and authenticating a user who is trying to associate to a wired or wireless network. WPA-Enterprise uses TKIP with RC4 encryption, while WPA2-Enterprise adds AES encryption. 802.1X can be transparent to wireless users. 802.1X utilizes the Extensible Authentication Protocol (EAP) to establish a secure tunnel between participants involved in an authentication exchange.

What is needed to use WPA/WPA2 Enterprise on a Wi-Fi network? A RADIUS server TACAC+ A hardware token It is not possible

A RADIUS server Remote Authentication Dial-In User Service (RADIUS) is a client-server networking protocol that runs in the application layer. The RADIUS protocol uses a RADIUS Server and RADIUS Clients. A RADIUS Client (or Network Access Server) is a networking device (like a VPN concentrator, router, switch) that is used to authenticate users. A RADIUS Server is a background process that runs on a UNIX or Windows server. It lets you maintain user profiles in a central database. Hence, if you have a RADIUS Server, you have control over who can connect with your network. When a user tries to connect to a RADIUS Client, the Client sends requests to the RADIUS Server. The user can connect to the RADIUS Client only if the RADIUS Server authenticates and authorizes the user

The Chief Information Officer of the company is worried that PII still remains on these old workstations, which of the following with BEST solve the concern and allow the company to donate the old workstations? Drill or hammer Incineration Overwriting Formatting

Overwriting Don't format, overwrite. The key isn't to format or erase a hard drive, as Windows will allow you to do. That just hides a file from view. To secure it, you'll need to overwrite the entire thing with 1's and 0's, creating a random sea of bits. And you'll need to do it over and over, just to be sure.

Ransomware Ransomware is a type of malicious software (malware) that threatens to publish or blocks access to data or a computer system, usually by encrypting it, until the victim pays a ransom fee to the attacker. In many cases, the ransom demand comes with a deadline. If the victim doesn't pay in time, the data is gone forever or the ransom increases.

Which of the following is a complimentary instruction set that extends the capabilities of a CPU? RISC SSE2 EIDE SSID

SSE2 = Streaming SIMD Extensions 2 One of the Intel SIMD (Single Instruction, Multiple Data) processor supplementary instruction sets first introduced by Intel with the initial version of the Pentium 4 in 2000. It extends the earlier SSE instruction set, and is intended to fully replace MMX. RISC (reduced instruction set computer) is a microprocessor that is designed to perform a smaller number of types of computer instructions so that it can operate at a higher speed (perform more millions of instructions per second, or MIPS EIDE = Enhanced (sometimes "Expanded") IDE is a standard electronic interface between your computer and its mass storage drives. EIDE's enhancements to Integrated Drive Electronics (IDE) make it possible to address a hard disk larger than 528 Mbytes. SSID = stands for Service Set IDentifier and is your network's name

Why should you avoid using WEP on the Wi-Fi network? It is an old Cisco-only standard The initialization vectors aren't random enough It is still okay to use but there are better solutions User authentication is too complicated

The initialization vectors aren't random enough (WEP) Wired Equivalent Privacy. Wireless encryption standard. The main problem with WEP is that it only uses one static key when sending data from your computer. This wasn't a problem when WEP first arrived; however, as time went on, hackers cracked the code behind the keys. As such, once a hacker knows the key for your Wi-Fi communication, they can break the encryption and read the data you're sending.
