CYSE 101 FINAL STUDY SET questions and correct answers 2023(UPDATED) What is access control? - correct answer A security technique that regulates who or what can view or use resources in a computing environment It enables administrators to manage access at a more granular level Authentication - correct answer Authentication is the step after identification It is to determine whether the claim of the identity is true Because access control is typically based on the identity of the us...

A ______________ is an intelligent hub because it knows the addresses of the systems connected on each outbound port. Instead of repeating traffic on every outbound port, it repeats traffic only out of the port on which the destination is known to exist. Repeater Switch Bridge Router correct answers Switch A password that requires users to answer a series of questions like "What is your mother's maiden name?" or "What is your favorite color?" is known as what type of password? A...

ITN 262 Chapter 8 Test Questions with All Correct Answers The simplest technique for key wrapping is called _____ ________. It uses xor to perform the wrapping. - Answer- key splitting. In ____ ________, the ideal KEK is not constructed from a passphrase. Both the CEK and KEK should be generated from a truly random source. - Answer- key splitting When we wrap keys, we perform two completely separate encryptions. The first encryption protects the data by using CEK. The second encryption p...

NCTI WIFI (2022/2023) Rated A+ Notes Single input, single output (SISO) - Most systems have one radio and one antenna, and some systems have one radio and two antennas. Multiple input, multiple output (MIMO) - These systems use multiple radio chains in a single wireless chipset. Multi-user MIMO (MU-MIMO) - These systems use each radio chain on an access point to transmit to a unique client.Correct answer: Wired Equivalent Protection (WEP) - This type of security setup should never be use...
