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.

Recording user actions is an example ofaccounting, which helps track what users do on a system, especially for auditing purposes.

“Accounting refers to the recording and logging of system activities, including tracking user actions within applications or services.” — CompTIA ITF+

Correct answer: A

Accounting refers to the logging and monitoring of user actions. In this case, tracking login events through log files is an example of accounting in the AAA (Authentication, Authorization, Accounting) model.

“Accounting provides auditing and logging of user actions, such as login times and resource access.” — CompTIA ITF+ Security Essentials

Correct answer: A

The CompTIA Tech+ Study Guide explains:

“A compiled programming language is one that requires the use of a compiler to translate it into machine code. Creating and using a program using a compiled language consists of three steps:

Write the source code.

Use a compiler to translate the source code into machine code.

Execute the program file, which usually has an .exe extension.”

Compiled languages package programs into executable files.

A byte consists of exactly 8 bits. Bits (binary digits) are the smallest unit of data, and eight of them grouped together form one byte, which is used to represent characters and numbers in digital systems.

“A byte is made up of 8 bits and is the standard unit of data used to represent information such as characters in computing.” — CompTIA ITF+ Fundamentals

Correct answer: C

According to the CompTIA Tech+ Study Guide:

“Changing Default Usernames and Passwords — The first thing a potential hacker will try to use is the default username or password for a device. Always change them.”

It also emphasizes:

“Enabling passwords and changing default usernames and passwords are essential password management best practices.”

Therefore, the correct action after server setup is to change the default usernames and passwords to secure the system.

This structure uses branching, which allows a program to make decisions based on conditions using "if," "else if," and similar statements.

“Branching allows the flow of execution in a program to change based on decisions or conditions.” — CompTIA ITF+ Programming Concepts

Correct answer: D

A primary key is a unique identifier for each record in a database table. It must be unique and not null across all rows. In this table, the field ID is the only column that uniquely identifies each row and does not repeat.

“A primary key is a field (or a set of fields) that uniquely identifies a record in a table. It ensures that each record can be uniquely retrieved.” — CompTIA ITF+ Official Study Guide

Analysis of other options:

Month, Day, Year, and Name can have duplicate values across multiple records and therefore do not serve as unique identifiers.

Correct answer: A

The ID field contains unique values for each record and is typically used as a primary key in a database. A primary key uniquely identifies each row in a table.

Month, Day, Year, and Name may have duplicates and do not guarantee uniqueness.

A cable lock (also called a Kensington lock) physically secures the laptop to a fixed object, making it difficult to steal in public spaces.

“Cable locks are physical security devices used to deter laptop theft by anchoring the device to a desk or other stationary object.” — CompTIA ITF+ Official Guide

A. Firewall is software-based and protects data, not the device.

B. Privacy shields prevent screen visibility, not theft.

C. USB locks prevent port access but not physical theft.

Correct answer: D

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), one of the five critical steps when configuring a wireless router is to change the administrator username and password:

“The Wi-Fi Alliance lists five critical keys to setting up a secured wireless router:

Change the router’s SSID.

Change the administrator username and password. Make sure that it’s a strong password.

Enable WPA3 or WPA2 Personal.

Choose a strong security passphrase.

Connect clients using the same security mode.”

This ensures unauthorized users cannot log in to the router’s settings.
