CompTIA Tech+ Certification Exam FC0-U71 Practice Questions

Answer : A

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.

Answer : A, B

Personally Identifiable Information (PII) refers to any data that can be used to identify an individual uniquely. Full name and date of birth are classic examples of PII.

''PII includes data such as names, birth dates, Social Security numbers, and other information that can directly or indirectly identify a person.'' --- CompTIA ITF+ Security Essentials

Correct answers: A and B

Answer : D

Recording user actions is an example of accounting, 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 answe r: A

Answer : D

In the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), the section on wireless encryption options explains:

''Exam objective 6.5 specifies that you should know Wi-Fi encryption options such as an open network, preshared key, WPA, WPA2, and WPA3... Focus on understanding that open networks are unsecure, and that WPA3 is better than WPA2, which is better than WPA.''

Further, it describes open networks as:

''Open portals pose security risks to the network and to users on the network. Use them with caution.''

Therefore, to allow anyone in the community to connect freely, the router must be set to Open (no password or encryption).

Answer : D

The correct answer is D. Integrity. The phrase ''contents are unchanged'' directly refers to whether data has remained accurate, consistent, and unaltered. In security, integrity is the principle that protects data from unauthorized or accidental modification. Confidentiality is about keeping private data from unauthorized viewing. Authentication verifies identity. Availability ensures systems or data can be accessed when needed. Only integrity matches checking that a downloaded file has not changed.

Exact Extract/Reference: The Tech+ Study Guide explains that integrity means ''the data is accurate and consistent and from the indicated source,'' and identifies data integrity concerns such as unauthorized information alteration. The guide's summary also states that integrity is ensuring data is ''true and correct.''

Answer : C

The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) explains:

''Inside the BIOS, you can make system configuration selections such as changing the system time, selecting a preferred boot device, or enabling/disabling features.''

Additionally, it details:

''The CMOS chip must have power constantly or it will lose its information (just like RAM does when your computer is powered off). To prevent CMOS from losing its rather important information, motherboard manufacturers include a small battery called the CMOS battery to power the CMOS memory.''

If the system time resets or becomes incorrect after power off, it indicates a BIOS or CMOS battery issue. Configuring or replacing the BIOS/CMOS settings resolves it.

Answer : D

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.
