The requirement to change passwords every 60 days is a policy known aspassword expiration. It is part of enforcing secure authentication by limiting the amount of time a password is valid.

“Password expiration is a security measure that requires users to change their passwords after a specific period, such as every 60 or 90 days, to reduce the risk of compromised credentials being used over time.” — CompTIA ITF+ Official Guide

Password complexity refers to rules about what characters are required.

Password management refers to overall policies and tools for handling passwords.

Password privacy relates to confidentiality but not periodic resets.

Thus, the correct choice is C.

Anaccess pointis a networking hardware device that allows wireless devices to connect to a wired network using Wi-Fi or related standards. It helpsextend the rangeof 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:

Amodemconnects to the internet via an ISP.

Aserverprovides network services, not range.

Ahost firewallprotects a single device or network; it does not expand connectivity.

Thus, the most appropriate answer is D.

The most important consideration when opening a file on anOperating System Graphical User Interface (OS GUI)is thefile extension. A file extension identifies thetype of fileanddetermines which software application can open it. In the official CompTIA ITF+ Student Guide, it is stated that:

“The last part of the file name represents anextension, which describes what type of file it is and is used by Windows to associate the file with an application.”

“Files are usually opened by double-clicking them. You may want to open a file in a software product other than the default, however. When you right-click a file, the shortcut menu displays a list of suitable choices, or you can chooseOpen Withand browse for a different application. You can also use the Default Programs applet to configure file associations.”

“Do not change a file's extension if it is shown. If you delete or change the extension, the file will not be associated with the correct program for opening it.”

This means the OS uses thefile extensionto decide which application to use to open a file.Changing or deleting the extensioncan result in the file not opening properly because it no longer matches the program expected to open it.

Data monetizationrefers to generating revenue from data assets, such as selling access or insights from collected user data to third parties.

“Data monetization involves using data to generate economic value — for example, selling user data to vendors or advertisers.” — CompTIA ITF+ Data Concepts

Correct answer: A

A relational database uses tables consisting of rows and columns where a primary key uniquely identifies each row (record). As stated in the CompTIA ITF+ FC0-U71 Official Study Guide:

"Relational databases store data in tables consisting of rows and columns. Each table has a primary key, which uniquely identifies each record."

"Document and key/value databases are types of NoSQL databases and do not use primary keys in the same structured tabular format."

Non-structured databases (like object storage or big data repositories) do not enforce primary keys.

USB-Csupports bidirectional communication, which means it can both send and receive data, including video, audio, power, and data signals over the same cable. This is unlike traditional video cables such as VGA, DVI, or even DisplayPort, which primarily transmit data in one direction.

“USB-C is a reversible connector capable of transmitting power, data, video, and audio signals. It is also bidirectional, allowing two-way communication between devices.” — CompTIA ITF+ Study Guide

VGA,DVI, and evenDisplayPortare primarily unidirectional video outputs.

OnlyUSB-Cfully supports modern bidirectional multimedia communication.
