Question #11
A flatbed scanner that is connected to a laptop is used to convert photographic prints to digital images for reproduction on a color printer.
Which of the following is considered the input device for this process?
- A . Laptop hard drive
- B . Laptop keyboard
- C . Photographic prints
- D . Flatbed scanner
- E . Color printer
Correct Answer: D
D
Explanation:
An input device is a hardware component that allows users to enter data or commands into a computer system. A flatbed scanner is an input device that scans documents or images and converts them into digital data that can be stored, edited, or printed. A flatbed scanner is connected to a laptop via a peripheral device interface, such as USB or Bluetooth. A laptop hard drive, a laptop keyboard, and a color printer are not input devices, but storage, input, and output devices respectively. Photographic prints are not devices at all, but physical objects that can be scanned by an input device.

Question #13
Which of the following best describes the process of comparing MD5 values after downloading software?
- A . Verifying encryption
- B . Safe browsing practices
- C . Patching and updating
- D . Validating legitimate sources
Correct Answer: D
D
Explanation:
The process of comparing MD5 values (hashes) after downloading software is primarily used to validate that the software source is legitimate and the file has not been altered or corrupted during download. MD5 is a widely used cryptographic hash function that produces a 128-bit hash value. By comparing the MD5 hash provided by the software distributor with the hash of the downloaded file, you can verify that the file is exactly what the distributor intended to deliver, without any modifications, whether malicious or accidental.
Reference: This verification method is discussed in CompTIA IT Fundamentals study materials as a part of understanding security measures to ensure data integrity and protection against tampering.

Question #14
Which of the following storage types uses platters to store data?
- A . Hard drive
- B . Solid-state drive
- C . Optical drive
- D . Flash drive
Correct Answer: A
A
Explanation:
A hard drive, also known as a hard disk drive (HDD), is a type of storage device that uses one or more rotating platters coated with magnetic material to store data. The platters are accessed by read/write heads that move across the surface of the platters as they spin. The data is stored as tiny magnetic regions on the platters, which can be changed or read by the heads. Hard drives are non-volatile, meaning they retain data even when power is off. Hard drives offer large storage capacity, low cost per gigabyte, and fast data transfer rates compared to other storage types. However, they are also prone to mechanical failures, noise, heat, and physical damage

Question #16
A network technician is installing an RJ11 connector inside a home tor new internet service.
Which of the following network connection types is the technician most likely using?
- A . Fiber
- B . DSL
- C . Satellite
- D . Cable
Correct Answer: B
B
Explanation:
DSL stands for Digital Subscriber Line, which is a type of broadband internet service that uses copper telephone cabling. A network technician installing an RJ11 connector, which is the standard connector for telephone lines, is most likely using DSL as the network connection type. Fiber, satellite, and cable are other types of internet service, but they use different connectors and cables than RJ11.

Question #17
During a meeting, managers spoke of several instances in which confidential information appeared on inappropriate websites. The company also discovered its firewall did not filter out certain traffic to prevent such issues.
Which of the following most likely exposed the confidential information?
- A . Instant messaging
- B . Mobile applications
- C . Social media
- D . Video-sharing website
Correct Answer: C
C
Explanation:
Social media platforms are common channels through which confidential information may inadvertently or maliciously be exposed due to their wide accessibility and the ease with which information can be shared. The scenario described suggests that the firewall did not filter certain types of outbound traffic, which could include access to social media sites where sensitive data might be posted or leaked.
Reference: CompTIA IT Fundamentals documents often emphasize the role of network security protocols and configurations, including content filtering and firewalls, as critical for protecting against data leaks, particularly via platforms like social media.

Question #19
A programmer creates an object to retrieve customer names from a database.
Which of the following best describes the object that is retrieving the names?
- A . Variable
- B . Attribute
- C . Method
- D . Looping
Correct Answer: C
C
Explanation:
In object-oriented programming (OOP), a method is a function associated with an object and is used to perform operations on that object. When a programmer creates an object to retrieve customer names from a database, the operation that retrieves the names is typically encapsulated in a method. This method might be called something like getCustomerNames() and is responsible for querying the database and returning the results.
Reference: Basic concepts of OOP, including objects and methods, are foundational topics in programming and are discussed in CompTIA IT Fundamentals and other programming guides.

Question #20
Which of the following is best used to store many integers in one container?
- A . Array
- B . Function
- C . Variable
- D . Constant
Correct Answer: A
A
Explanation:
An array is the best choice for storing many integers in one container. An array is a data structure that can hold a fixed number of elements, which are all of the same data type. It is especially useful for storing a collection of data items at contiguous memory locations, allowing easy access to the elements using an index. Arrays are fundamental in programming for organizing data, allowing for efficient storage and quick access.
Reference: Arrays and their uses are basic concepts covered in programming fundamentals, frequently discussed in CompTIA IT Fundamentals and other introductory programming resources.
