Answer

Hidden

Answer

System

Answer

Archive

Question 2

A developer needs to track changes to source code over time, collaborate with other developers, and maintain a history of all modifications. Which tool is specifically designed for these tasks?

Accepted Answer

Git. Git is a version control system that tracks changes, enables collaboration, and maintains a history. An IDE is for writing code, a debugger finds errors, and a text editor edits text files but lacks version control features.

Answer

Text editor

Answer

Integrated Development Environment (IDE)

Answer

Debugger

Question 3

Which of the following is a valid SQL statement to retrieve all records from a table named 'Employees'?

Accepted Answer

SELECT * FROM Employees. The correct SQL statement to retrieve all records from a table named 'Employees' is SELECT * FROM Employees. The SELECT clause specifies the columns to return, and the asterisk (*) is a wildcard meaning all columns. The FROM clause specifies the table to query. This is standard SQL syntax defined by ANSI/ISO and supported by all major relational database management systems (RDBMS) such as MySQL, PostgreSQL, SQL Server, and Oracle.

Answer

GET * FROM Employees

Answer

FETCH * FROM Employees

Answer

READ * FROM Employees

Question 4

A programmer declares a variable 'price' and assigns it the value 19.99. In most programming languages, what is the data type of this variable?

Accepted Answer

Float. The value 19.99 contains a decimal point, which indicates a floating-point number. In most programming languages, such as Python, Java, C, and JavaScript, a numeric literal with a decimal point is treated as a float (or double) by default. Therefore, the data type of the variable 'price' is float.

Answer

Boolean

Answer

String

Answer

Integer

Question 5

Which TWO of the following are examples of security software? (Choose TWO.)

Accepted Answer

Antivirus. Antivirus (A) is security software because it detects, blocks, and removes malware such as viruses, worms, and trojans through signature scanning and behavioral heuristics. A Virtual Private Network (VPN) (D) is security software because it creates an encrypted tunnel (e.g., using IPsec or TLS) that protects data confidentiality and integrity in transit and can authenticate remote users. The media player (B), web browser (C), and text editor (E) are general-purpose application software for playback, web access, and text manipulation, respectively; they do not primarily provide security functions, so they are not examples of security software.

Answer

Media player

Answer

Web browser

Answer

Text editor

Question 6

A user needs to install a new graphics editing application on a Windows computer. Which file extension is most likely associated with the installer?

Accepted Answer

Answer

.deb

Answer

.pkg

Answer

.dmg

Question 7

Which of the following software licenses allows users to modify and redistribute the source code, provided they keep the same license terms?

Accepted Answer

GNU General Public License (GPL). The GNU General Public License (GPL) is a copyleft license that requires derivative works to be distributed under the same license terms. This means users can modify and redistribute the source code, but they must keep the same license, ensuring that the software remains free and open source.

Answer

Apache License

Answer

Commercial License

Answer

MIT License

Question 8

A technician is deploying a software update to 200 computers in a domain. To avoid user interaction, which installation method should be used?

Accepted Answer

Silent installation. A silent installation runs the installer with no user prompts or UI, using switches such as /quiet or /qn (MSI) or /S (setup.exe), which is essential when pushing an update to 200 domain machines via Group Policy, SCCM, or a similar deployment tool. Because no interaction is required, the update can run unattended across all endpoints simultaneously.

Answer

App store installation

Answer

Interactive installation

Answer

Manual installation

Question 9

Which of the following is a key difference between a web application and a desktop application?

Accepted Answer

Web applications run inside a browser and process data on a server; desktop applications run directly on the OS and have direct hardware access.. It accurately captures the architectural distinction: web applications execute within a browser's sandboxed environment and typically rely on remote servers for data processing and storage, while desktop applications are installed on the local machine, run natively on the operating system, and can directly access hardware resources like the file system, GPU, and peripherals. This difference in execution environment and resource access is the fundamental technical differentiator between the two application models.

Answer

Desktop applications are stored on a remote server; web applications are installed locally.

Answer

Web applications require an internet connection to run; desktop applications do not.

Answer

Desktop applications require a subscription; web applications are free.

Question 10

A user wants to edit a plain text configuration file on a Linux system. Which type of application is most appropriate?

Accepted Answer

Text editor. A text editor is the correct tool for editing plain text configuration files on Linux because it saves files without formatting, hidden characters, or proprietary markup. Editors like vi, nano, and emacs preserve the exact bytes needed for config files such as /etc/fstab or sshd_config. Using anything that adds formatting would corrupt the file and break the service.

Answer

Integrated Development Environment (IDE)

Answer

Word processor

Answer

Media player

Question 11

In a database, which SQL statement is used to add new records to a table?

Accepted Answer

INSERT INTO. The SQL INSERT INTO statement is used to add new records (rows) to a table. It specifies the target table and the values to insert, optionally listing columns. This is the standard DML statement for creating new rows in a relational database.

Answer

DELETE

Answer

UPDATE

Answer

SELECT

Question 12

A programmer writes code to run a block of instructions repeatedly until a condition is met. Which programming concept is being used?

Accepted Answer

Loop. A loop is a programming construct that repeats a block of instructions until a specified condition is met. The scenario describes exactly that: code that runs repeatedly until a condition becomes true. Loops are fundamental for iteration, such as processing items in a list or repeating a task until a user quits.

Answer

Conditional

Answer

Function

Answer

Variable

Question 13

A developer is using Git and wants to integrate changes from a feature branch into the main branch. Which Git operation should be performed?

Accepted Answer

Merge. The 'git merge' command integrates changes from one branch into another, typically merging a feature branch into the main branch. It combines the commit histories and creates a merge commit if necessary, preserving the context of both branches.

Answer

Branch

Answer

Commit

Answer

Clone

Question 14

A user downloads a freeware application that displays occasional ads and offers paid upgrade options. This distribution model is best described as:

Accepted Answer

Freemium. Freemium is the model where the base product is free but monetized through ads and/or paid premium upgrades. The scenario explicitly mentions both ads and paid upgrade options, which is the textbook definition of freemium. Freeware is free with no monetization path, and shareware is trial-limited software requiring payment to continue using.

Answer

Shareware

Answer

Freeware

Answer

Commercial

Question 15

Which of the following best describes the function of a web API?

Accepted Answer

It allows different software applications to communicate and exchange data.. A web API (Application Programming Interface) is a set of defined endpoints, protocols, and data formats that allow different software applications to communicate and exchange data over HTTP/HTTPS. It abstracts backend logic so clients (web apps, mobile apps, third-party services) can request and submit data without knowing internal implementation details. Common examples include REST APIs using JSON and SOAP APIs using XML.

Answer

It encrypts data transmitted between a web browser and server.

Answer

It is a programming language used to query databases.

Answer

It provides a graphical user interface for web applications.
