Question #2

Kevin logged into a banking application with his registered credentials and tried to transfer some amount from his account to Flora's account. Before transferring the amount to Flora's account, the application sent an OTP to Kevin's mobile for confirmation.

Which of the following authentication mechanisms is employed by the banking application in the above scenario?

Reveal Solution Hide Solution
Correct Answer: D

Two-factor authentication (2FA) is a type of authentication that requires users to provide two or more forms of verification to access an online account. 2FA is a multi-layered security measure designed to prevent hackers from accessing user accounts using stolen or shared credentials. 2FA typically combines something the user knows (such as a password or PIN), something the user has (such as a phone or a token), and/or something the user is (such as a fingerprint or a face scan). In the above scenario, the banking application employs 2FA by asking Kevin to enter his registered credentials (something he knows) and an OTP sent to his mobile (something he has) before transferring the amount to Flora's account.

Question #4

Which of the following environmental controls options saves the hardware from humidity and heat,

increases hardware performance, and maintains consistent room temperature?

Reveal Solution Hide Solution
Correct Answer: A

Hot and cold aisles are a type of environmental control that saves the hardware from humidity and heat, increases hardware performance, and maintains consistent room temperature. Hot and cold aisles are a layout design for data centers, where the server racks are arranged in alternating rows of cold air intake and hot air exhaust. The cold aisle faces the air conditioner output ducts and provides cool air to the front of the servers. The hot aisle faces the air conditioner return ducts and collects the hot air from the back of the servers. This way, the hot and cold air streams are separated and do not mix, resulting in better cooling efficiency, lower energy consumption, and longer hardware lifespan. Reference:

Question #5

Kevin, a security team member, was instructed to share a policy document with the employees. As it was supposed to be shared within the network, he used a simple algorithm to encrypt the document that just rearranges the same characters to produce the ciphertext.

Identify the type of cipher employed by Kevin in the above scenario.

Reveal Solution Hide Solution
Correct Answer: C

A transposition cipher is a type of cipher that encrypts a document by rearranging the same characters to produce the ciphertext. A transposition cipher does not change the identity or frequency of the characters, but only their position. A transposition cipher can use various methods to permute the characters, such as writing them in a grid and reading them in a different order, or shifting them along a rail fence pattern. A transposition cipher is a simple and fast algorithm, but it can be easily broken by frequency analysis or anagramming. A transposition cipher is the type of cipher employed by Kevin in the above scenario, as he used a simple algorithm to encrypt the document that just rearranges the same characters to produce the ciphertext.
