CompTIA Updated FC0-U71 Exam Questions and Answers by elina

Line 10 starts with “FOR Q=1 TO 100,” which is a loop construct. It defines a loop that will run 100 times, incrementing Q from 1 to 100 and executing the enclosed lines (20 and 30).

“Loops are programming constructs that repeat a set of instructions until a condition is met. A ‘FOR’ loop is a common control structure in procedural programming.” — CompTIA ITF+ Official Objectives

Other options:

Attribute applies to objects, not control flow.

Sequence is the overall flow of code lines.

Branches involve decision-making (e.g., IF/ELSE), not repetition.

Correct answer: D

RAM (Random Access Memory) in smartphones and computers is most commonly measured in gigabytes (GB) today. Typical smartphone RAM ranges from 2GB to 16GB depending on performance and price.

“Memory capacity in modern devices like smartphones is measured in gigabytes (GB), reflecting their need to support multitasking and app usage.” — CompTIA ITF+ Official Resources

Other options:

KB and MB were used in earlier computing generations.

TB is used for storage, not RAM.

Correct answer: A

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), the SFP (Small Form-Factor Pluggable) connector is directly associated with fiber-optic networking. The guide lists:

“SFP (small form-factor pluggable) connectors are commonly used in fiber-optic connections to allow hot-swappable transceivers for different types of fiber cables.”

Additionally, the same guide’s chapter on Networking Concepts and Technologies explains:

“Fiber-optic around 2 Gbps – Incredibly fast and more expensive than DSL or cable.”

Therefore, fiber Internet is the only service type that uses SFP connectors for data transmission over optical cables.

Chapter 8: Networking Concepts and Technologies — “External network connections” and “Common Internet connection types and speeds” (pp. 429–435).

Chapter 2: Peripherals and Connectors — “SFP (small form-factor pluggable) connectors” (pp. 97–98).

A loop is a programming construct that repeats a set of instructions while a condition is true. This is used to automate repetitive tasks in code.

“Loops are used in programming to execute the same block of code multiple times under specific conditions.” — CompTIA ITF+ Programming Concepts

Correct answer: A
