WGU Introduction to IT Sample Questions (Q33-Q38):

NEW QUESTION # 33
What does a router do?

Answer: B

Explanation:
A router manages network traffic by using a routing table to determine where data packets should be sent. In Information Technology networking, a router connects different networks, such as a home local network and the internet, and forwards packets based on destination IP addresses. The routing table contains information about known networks and the best path to reach them. This allows the router to direct traffic efficiently between networks and to serve as a gateway for devices on a local area network. Option A describes a server, which provides services like hosting websites or applications. Option C describes a repeater, which boosts or regenerates signals to extend cable distance. Option D describes a modem, which modulates and demodulates signals to convert between analog and digital forms for transmission over certain media. While modern home routers may also include switch and wireless access point features, the core routing function is traffic management using routing information. Therefore, the correct answer is the option describing maintaining a table and managing traffic, which is option B.


NEW QUESTION # 34
An IT department employee is identifying the Boolean data in a system. What is one example of this type of data?

Answer: D

Explanation:
Boolean data represents a logical value with only two possible states, typically true or false. In Information Technology, Boolean types are foundational for conditions, comparisons, control flow, and database fields that store yes-or-no style information. The example, "Whether a number is positive or not," fits Boolean data because the statement can be evaluated as true if the number is greater than zero, or false otherwise. This two- state characteristic is exactly what defines Boolean logic. The other options describe different data types: the first letter of a last name is a character, a full last name is a character string, and the price of gas in dollars and cents is numeric with decimals, typically stored as a floating-point or fixed-point decimal type. Boolean fields are widely used in systems for flags such as active or inactive, approved or not approved, and eligible or not eligible. Therefore, the correct example of Boolean data is whether a number is positive or not.


NEW QUESTION # 35
Which type of network is used to connect wireless headphones to a smartphone?

Answer: C

Explanation:
Wireless headphones typically connect to a smartphone using Bluetooth, which is an example of a personal area network. In Information Technology, a personal area network is a short-range network centered around an individual's devices, usually within a few meters. PAN technology is designed for low power usage and convenient device pairing, making it ideal for accessories such as headphones, smartwatches, fitness trackers, and wireless keyboards. A local area network covers a larger area such as a home, office, or campus and commonly uses Ethernet or Wi-Fi to connect computers and network devices. A wide area network spans large geographic distances and connects networks across cities, countries, or continents, often using leased lines or internet infrastructure. Extended area network is not a standard category used in most networking fundamentals curricula compared with PAN, LAN, MAN, and WAN. Since the connection between headphones and a phone is short-range and personal, it is best classified as a personal area network.
Therefore, the correct answer is PAN.


NEW QUESTION # 36
Why is business continuity planning essential?

Answer: D


NEW QUESTION # 37
Which component comes in two varieties, one that mechanically writes binary data onto spinning magnetic disks and one that writes data with no mechanical parts?

Answer: A

Explanation:
The hard drive category includes two common storage varieties: traditional hard disk drives and solid-state drives. A hard disk drive stores binary data magnetically on spinning platters and uses mechanical parts such as a rotating motor and moving read and write heads. In contrast, a solid-state drive stores data using non- volatile flash memory with no moving mechanical components. In Information Technology hardware concepts, both serve the same role as secondary storage, meaning they store files, applications, and the operating system persistently even when power is off. Hard disk drives are often lower cost per gigabyte and are common in large-capacity storage, while solid-state drives provide faster access times, improved performance, and better resistance to physical shock. The motherboard is the main circuit board, the system clock provides timing pulses, and an expansion bus is a communication pathway for add-on devices. Since the question describes mechanical and non-mechanical storage types, the correct component is the hard drive.
