Answer : B

The code uses a for loop to iterate from 1 to 3, and assigns the value of i to the variable x. Then, it adds 3 to x and prints the result. The output of the code is:

3 (when i = 1, x = 1, x + 3 = 4) 6 (when i = 2, x = 2, x + 3 = 5) 9 (when i = 3, x = 3, x + 3 = 6)

Answer : B

802.11b is the wireless standard that supports speeds up to 11Mbps and operates on the 2.4GHz band. 802.11b is one of the earliest versions of the IEEE 802.11 family of standards for wireless local area networks (WLANs). 802.11b uses direct-sequence spread spectrum (DSSS) modulation to transmit data over radio waves. 802.11b has a maximum theoretical data rate of 11Mbps and a typical range of up to 150 feet indoors or 300 feet outdoors. 802.11b operates on the same frequency band as some cordless phones, microwaves, and Bluetooth devices, which may cause interference or signal degradation.Reference: The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 171.

Answer : D

Single-factor authentication is a method of verifying a user's identity by using only one piece of information, such as a username and password. Biometrics, multifactor authentication, and least privilege are not examples of single-factor authentication.Reference: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 304.

Answer : B

An if statement is a programming construct that is best to use when a program needs to choose among different options based on an input. An if statement evaluates a condition and executes a block of code if the condition is true. An if statement can also have an else clause that executes a different block of code if the condition is false. An if statement can also have multiple else-if clauses that check for additional conditions. For example, a program that chooses apples, oranges, or bananas based on an input could use an if statement like this:

A variable is a named memory location that can store a value, not a programming construct that can choose among options. A datatype is a classification of data that defines the possible values and operations for that data, not a programming construct that can choose among options. A comment is a remark or explanation in the source code that is ignored by the compiler or interpreter, not a programming construct that can choose among options.

Answer : C

RJ11 is a type of connector that is used for telephone lines. RJ11 has four copper wires that carry analog voice signals. RJ11 is smaller than RJ45, which is used for Ethernet cables. RJ11 is also different from VGA and USB, which are used for video and data transmission respectively.Reference: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 4, Section 4.2, Page 166.
