A user purchased a new smart home device with embedded sofware and connected the device to a home network. Te user then registered the device with the manufacturer, setting up an account using a personal e-mail and password. Which of the following explains how a phishing attack could occur against the user of the smart home device?

• A vulnerability in the device’s software is exploited to gain unauthorized access to other devices on the user’s home network.

A Web site uses several strategies to prevent unauthorized individuals from accessing user accounts. Which of the following is NOT an example of multifactor authentication?

• Each employee for a company is issued a USB device that contains a unique token code. To log into a company computer, an employee must insert the USB device into the computer and provide a correct password

• When a user enters an incorrect password more than two times in a row, the user is locked out of the account for 24 hours.

A list of numbers has n elements, indexed from 1 to n. The following algorithm is intended to display the number of elements in the list that have a value greater than 100. The algorithm uses the variables count and position. Steps 3 and 4 are missing. Which of the following could be used to replace steps 3 and 4 so that the algorithm works as intended?

• Step 3: Increase the value of position by 1. Step 4: Repeat steps 2 and 3 until the value of count is greater than 100.

• Step 3: Increase the value of position by 1. Step 4: Repeat steps 2 and 3 until the value of position is greater than n

• Step 3: Repeat step 2 until the value of count is greater than 100. Step 4: Increase the value of position by 1

• Step 3: Repeat step 2 until the value of position is greater than n. Step 4: Increase the value of count by 1.

The following code segment is intended to set max equal to the maximum value among the integer variables x, y, and z. The code segment does not work as intended in all cases. Which of the following initial values for x, y, and z can be used to show that the code segment does not work as intended?

• x = 1, y = 2, z = 3

• x = 1, y = 3, z = 2
