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.

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.

Correct answer: D

Apassword reusepolicy prevents users from using the same password across multiple platforms or reusing previously used passwords. This is a best practice to reduce the risk of credential stuffing attacks.

“Password reuse policies help ensure users do not reuse old or existing passwords across multiple platforms, reducing exposure from compromised accounts.” — CompTIA ITF+ Security Objectives

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.

The syntax shown uses tags like and

, which are characteristic of amarkup language, specifically HTML (HyperText Markup Language). Markup languages describe the structure and presentation of text.

“Markup languages, such as HTML and XML, are used to annotate text so that the computer can manipulate it. HTML is used to design the structure of web pages using tags like ,

,

, etc.” — CompTIA ITF+ Official Guide

Other options:

Query languages like SQL retrieve data.

Compiled languages require compilation into machine code (e.g., C++).

Scripting languages are used for automation but don’t use markup syntax.
