    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: C

    Explanation

    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.

    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: D

    Explanation

    According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025):

    “The rules and structure of the database are called its schema. It defines the tables, forms, reports, queries, data types allowed, and pretty much everything else about the database.”

    It also clarifies:

    “The logical schema outlines the structure of the database, such as the tables and their fields (columns), and relationships between tables.”

    Thus, an outline of a database’s structure is called a schema.

    Verified Reference:

      Chapter 7: Database Fundamentals — “Schema” (pp. 392–393).

  3. Question 3

    • Option A:

      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: A

    Explanation

    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.

    Verified Reference:

      Chapter 11: Security Best Practices — “Managing Passwords” (pp. 594–595).

  4. Question 4

    Single answer

    Which of the following describes a use case for a flash drive?

    • Option A:

      A user needs to back up a local file so work can continue at home.


      Correct
    • Option B:

      A user needs a file to be accessible anywhere over the Internet.


      Correct
    • Option C:

      A user needs to share a file over a local area network.


      Correct
    • Option D:

      A user needs to archive a file for long-term storage.

      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: A

    Explanation

    The correct answer is A. A flash drive is a small, portable local storage device, so it is useful when a user needs to copy or back up a local file and carry it to another location, such as home. Option B describes cloud storage. Option C describes network file sharing. Option D describes long-term archiving, which is not the best use case for a flash drive because flash drives are small, easy to misplace, and not ideal as long-term archive media.

    Exact Extract/Reference: The CompTIA Tech+ Study Guide defines an external flash drive as “a small, portable SSD that connects through a USB port” and says its “primary benefit is portability.” The guide also lists flash drives as a locally attached backup storage option.

  5. Question 5

    • Option A:

      802.11X


      Correct
    • Option B:

      Thunderbolt


      Correct
    • Option C:

      Bluetooth


      Correct
    • Option D:

      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: A

    Explanation

    Tablets typically connect to wireless networks using Wi-Fi, which adheres to the IEEE 802.11 standard (often seen as 802.11a/b/g/n/ac/ax). The correct protocol family for this type of connection is 802.11X (referring to Wi-Fi technologies broadly).

    “Wireless devices such as tablets use the 802.11 standards to connect to Wi-Fi access points for network connectivity.” — CompTIA ITF+

    Other options:

      B. Thunderbolt and D. USB-C – Wired connection standards

      C. Bluetooth – Short-range peripheral communication, not Wi-Fi

    Correct answer: A
