A programmer needs to create a space in an application code to hold a value. The value will be updated periodically when the code is executed.
Which of the following should the programmer use?
- A . Variable
- B . Sequence
- C . Loop
- D . Constant
A
Explanation:
A variable is a named space in memory used to store data that can change during program execution.
“Variables are memory storage locations used to hold data that can change while a program runs.” ― CompTIA ITF+ Programming Concepts
Correct answer: A
Which of the following devices extends the range of a network?
- A . Modem
- B . Server
- C . Host firewall
- D . Access point
D
Explanation:
An access point is a networking hardware device that allows wireless devices to connect to a wired network using Wi-Fi or related standards. It helps extend the range of a wireless network by creating additional coverage areas.
This is directly outlined in CompTIA ITF+ documentation:
“A wireless access point (AP) is a device that allows wireless clients to connect to a wired network. It serves to extend or broaden the wireless coverage.”
In contrast:
A modem connects to the internet via an ISP.
A server provides network services, not range.
A host firewall protects a single device or network; it does not expand connectivity.
Thus, the most appropriate answer is D.
Which of the following is the last tool that should be used when creating a custom-length network cable?
- A . Cable tester
- B . Crimper
- C . Wire cutter
- D . Ethernet connector
A
Explanation:
The correct order for creating a network cable:
Measure and cut with wire cutter
Strip the wires
Attach Ethernet connector using a crimper
Finally, test the cable with a cable tester to ensure connectivity and proper pinout.
“After crimping the RJ-45 connectors, a cable tester is used to validate the electrical continuity and correct wiring order.” ― CompTIA ITF+ Curriculum
Correct answer: A
A user wants to connect to a home’s Wi-Fi from the basement but is unable to do so.
Which of the following is a potential cause of the issue?
- A . Interference
- B . Speed
- C . Synchronization
- D . Permission
A
Explanation:
Interference or poor signal strength is a common issue in Wi-Fi networks, especially in distant or obstructed locations like basements.
“Physical obstructions and electronic interference can weaken wireless signals, leading to connectivity issues in areas like basements.” ― CompTIA ITF+ Networking Fundamentals
Correct answer: A
A user lives in a remote area that does not have cabling or towers available. The user wants to connect to the internet.
Which of the following is the best solution?
- A . Fiber optic
- B . IDSL
- C . Cellular
- D . Satellite
D
Explanation:
For locations without cable or cellular towers, satellite internet is the most viable solution. Satellite does not require terrestrial infrastructure beyond a dish and has global coverage.
“Satellite is often used in remote or rural locations where wired and cellular connectivity is not available. It uses a dish to communicate with orbiting satellites for internet access.” ― CompTIA ITF+ Curriculum
Fiber optic and IDSL require ground cabling.
Cellular requires nearby towers, which the scenario rules out.
Correct answer: D. Satellite
More than 90 days have elapsed since a user created an account for a banking website. The next time the user attempts to log in, they receive a prompt to create a new password.
Which of the following is the bank enforcing?
- A . Password length
- B . Password history
- C . Password complexity
- D . Password expiration
A database has the following schema (as shown in the images above):
Which of the following is the number of records in the schema?
- A . 3
- B . 4
- C . 12
- D . 21
B
Explanation:
In the database schema shown in the images, there are four rows (excluding the header row) representing data entries for four people (John, Jane, Allison, and Anna).
Each row represents a record in the database table, also known as a tuple. The term record refers to a complete set of fields (ID, Name, and Age) for one entry.
So, counting the four rows:
John
Jane
Allison
Anna
That makes a total of 4 records in the database schema.
Reference: The official CompTIA ITF+ Study Guide states:
"A record (or tuple) in a database is a complete set of fields that represents one entity C for example, a single row in a database table."
Thus, the correct answer is B.
Which of the following describes a printer?
- A . Processing
- B . Output
- C . Storage
- D . Input
B
Explanation:
A printer is an output device because it receives digital data from a computer and converts it into a printed physical format (such as paper).
“Output devices display or reproduce information from the computer. Examples include monitors, speakers, and printers.” ― CompTIA ITF+ Fundamentals
Correct answer: B
An application is unresponsive.
Which of the following will close the application?
- A . Task management
- B . System utilities
- C . Remote assistance
- D . File permissions
A
Explanation:
Task management tools such as Task Manager in Windows or Activity Monitor in macOS allow users to monitor running applications and processes. They also provide the functionality to force-close (end) applications that are not responding.
“Task Manager provides a way to close applications that are unresponsive and manage running processes.” ― CompTIA ITF+ Official Guide
Correct answer: A
A user is trying to view a report via a hyperlink on a website. When the user clicks on the hyperlink, nothing happens.
Which of the following must be configured to view the report?
- A . Cache clearing
- B . Accessibility options
- C . Pop-up blocker
- D . Private browsing
C
Explanation:
Pop-up blockers prevent new windows or tabs from opening, which can block reports that open in pop-up windows:
“If a web page uses pop-up windows to present information, a pop-up blocker may prevent the new content from loading.”
Cache clearing, accessibility options, or private browsing don’t directly affect hyperlink behavior.
