Question 1

Which of the following is the decimal equivalent of the binary number 1101?

Accepted Answer

13. Binary 1101 converts to decimal by summing the place values where bits are 1: (1×8) + (1×4) + (0×2) + (1×1) = 8 + 4 + 0 + 1 = 13. Therefore the decimal equivalent is 13.

Question 2

An organization uses a security model where users are granted the minimum permissions necessary to perform their job functions. This model is known as:

Accepted Answer

Principle of least privilege. The principle of least privilege (PoLP) states that users, processes, and systems should be granted only the minimum access rights required to perform their legitimate functions, and only for the duration needed. The scenario's wording — 'minimum permissions necessary to perform their job functions' — is the textbook definition of PoLP. It is a foundational security principle (codified in NIST SP 800-53 AC-6) rather than an access control model per se, though it is often implemented through RBAC.

Answer

Role-based access control

Answer

Mandatory access control

Answer

Discretionary access control

Question 3

Which TWO of the following are best practices for creating strong passwords?

Accepted Answer

Avoid using dictionary words or common phrases. Option B is correct because avoiding dictionary words and common phrases defends against dictionary and brute-force attacks, since attackers routinely test known words, leaked password lists, and predictable phrases first. Option D is correct because including a mix of uppercase, lowercase, numbers, and symbols increases the search space (entropy) an attacker must exhaust, making the password significantly harder to crack. Option A is incorrect because 'password123' is a well-known, commonly breached pattern that appears in every attacker wordlist. Option C is incorrect because personal information such as birth dates is easily discoverable and often guessable through social engineering or OSINT. Option E is incorrect because writing a password on a sticky note attached to the monitor exposes it to anyone who can physically see the workstation, defeating the purpose of the credential.

Answer

Use a common pattern like 'password123'

Answer

Use easily remembered personal information like birth dates

Answer

Write the password on a sticky note and attach it to the monitor

Question 4

A user needs to print a large number of color brochures with high-quality images. Which type of printer would produce the best color output for this task?

Accepted Answer

Inkjet printer. Inkjet printers are the best choice for high-quality color brochures with images because they use liquid ink droplets to produce smooth gradients and fine detail, often at resolutions of 4800 x 1200 dpi or higher. They excel at color accuracy and are widely used for photo and marketing materials. Laser printers, while fast and sharp for text, typically have lower color fidelity for photographic images. Dot-matrix and thermal printers are not designed for high-resolution color graphics.

Answer

Dot-matrix printer

Answer

Laser printer

Answer

Thermal printer

Question 5

Which THREE of the following are common file formats for images?

Accepted Answer

.gif. Option C (.gif) is correct because GIF (Graphics Interchange Format) is a standard raster image format supporting indexed color and animation. Option D (.png) is correct because PNG (Portable Network Graphics) is a common lossless raster image format widely used for web graphics. Option E (.jpg) is correct because JPEG (.jpg) is a ubiquitous lossy compressed raster image format for photographs. Option A (.mp3) is incorrect because MP3 is an audio compression format, not an image format. Option B (.docx) is incorrect because DOCX is a Microsoft Word document format for text and rich content, not an image format.

Answer

.mp3

Answer

.docx

Question 6

Which of the following describes a nibble?

Accepted Answer

4 bits. A nibble is defined as 4 bits, which is exactly half of a standard byte (8 bits). It is also equivalent to one hexadecimal digit, since 4 bits can represent 16 distinct values (0–15). This makes the nibble a fundamental unit in low-level computing and hexadecimal notation.

Answer

8 bits

Answer

16 bits

Answer

2 bytes

Question 7

A user wants to ensure software is legitimate and free from malware before installation. Which THREE of the following are recommended practices?

Accepted Answer

Read user reviews and check hash values. Option B is correct because reading user reviews helps identify reports of bundled malware or suspicious behavior, and checking hash values (e.g., SHA-256) against the vendor-published checksum confirms the downloaded file has not been tampered with or corrupted. Option C is correct because downloading from the official vendor website ensures the software comes from a trusted, authoritative source rather than a third-party site that may repackage it with malware. Option D is correct because verifying digital signatures (e.g., Authenticode on Windows) cryptographically proves the installer was signed by the legitimate publisher and has not been altered since signing. Option A is not recommended because cracked versions bypass licensing and are a common vector for hidden malware and backdoors. Option E is not recommended because disabling antivirus removes a critical layer of protection and increases the risk of executing malicious code during installation.

Answer

Use a cracked version to save money

Answer

Disable antivirus to speed up installation

Question 8

A small office has five computers that need to share files and a printer. Which type of network should be set up?

Accepted Answer

LAN. A LAN (Local Area Network) is designed for a single, contained environment such as a small office, home, or single building, and is exactly the right scope for five computers sharing files and a printer. It provides high-speed connectivity over short distances using Ethernet or Wi-Fi, typically through a single switch or router. This matches the requirement of a small, localized group of devices sharing resources.

Answer

PAN

Answer

WAN

Answer

MAN

Question 9

A technician is troubleshooting a computer that fails to boot. The technician checks the system's low-level software stored on a chip on the motherboard. Which type of software is being inspected?

Accepted Answer

Firmware. Firmware is low-level software stored on a chip (such as a ROM, EEPROM, or flash chip) on the motherboard that provides basic control of hardware and initializes the system during boot. The BIOS/UEFI is a prime example of firmware, so inspecting the chip on the motherboard means inspecting firmware. This is distinct from drivers, applications, and the OS, which reside on storage devices.

Answer

Device driver

Answer

Application software

Answer

Operating system

Question 10

A user wants to save a photo with the highest quality but does not care about file size. Which file format should they use?

Accepted Answer

PNG. PNG uses lossless compression, so it preserves every pixel of the original photo without discarding detail, making it the best choice when quality matters more than file size. It also supports full color depth and alpha transparency, which JPEG cannot match.

Answer

JPEG

Answer

ZIP

Answer

MP3

Question 11

Which of the following is the binary representation of the decimal number 5?

Accepted Answer

0101. The decimal number 5 in binary is 0101, because 4 (2^2) + 1 (2^0) = 5. Reading the bits left to right as 8-4-2-1 place values: 0*8 + 1*4 + 0*2 + 1*1 = 5. This is the correct 4-bit binary representation of decimal 5.

Answer

0100

Answer

0011

Answer

0110

Question 12

A user notices that a file saved as a JPEG is smaller than the original BMP file. Which type of compression does JPEG typically use?

Accepted Answer

Lossy compression. JPEG typically uses lossy compression, which reduces file size by permanently discarding some image data, especially high-frequency color details that the human eye is less sensitive to. This is why a JPEG is much smaller than the original BMP, which is uncompressed. The trade-off is a slight loss of quality, but the size reduction is significant.

Answer

Run-length encoding

Answer

Uncompressed

Answer

Lossless compression

Question 13

A developer writes code in Python and runs it without compiling. This is an example of which type of language?

Accepted Answer

Scripting language. A scripting language is executed by an interpreter at runtime rather than being compiled into machine code ahead of time. Python is a classic example: the developer writes code and runs it directly, with the Python interpreter executing it line by line (or via bytecode compilation internally). This contrasts with compiled languages like C or Go, which require a build step.

Answer

Compiled language

Answer

Markup language

Answer

Query language

Question 14

A technician needs to install software on 50 company computers without user interaction. Which installation method should be used?

Accepted Answer

Silent installation. A silent installation runs the installer with no user interaction, using command-line switches like /quiet or /qn, which is exactly what is needed to deploy software to 50 computers unattended. It can be scripted or pushed via deployment tools (SCCM, Intune, PDQ) to all machines simultaneously. Manual, app store, and trial installations all require user interaction or are not designed for bulk unattended deployment.

Answer

Manual installation

Answer

Installation from an app store

Answer

Trial installation

Question 15

Which programming data type would be used to store a value of 'True' or 'False'?

Accepted Answer

Boolean. A Boolean data type is specifically designed to hold one of two truth values: True or False. It is named after mathematician George Boole and is fundamental to conditional logic, comparisons, and control flow in programming. Storing 'True' or 'False' in any other type would be semantically incorrect and would lose the type's logical meaning.

Answer

String

Answer

Float

Answer

Integer
