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.

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.”

For locations without cable or cellular towers, satellite internet is the most viable solution. Satellite does not require terrestrial infrastructure beyond a dish and has global coverage.

“Satellite is often used in remote or rural locations where wired and cellular connectivity is not available. It uses a dish to communicate with orbiting satellites for internet access.” — CompTIA ITF+ Curriculum

Fiber optic and IDSL require ground cabling.

Cellular requires nearby towers, which the scenario rules out.

Correct answer: D. Satellite
