The largest unit is determined by converting all values to the same unit:

2TB = 2,000GB

100GB = 100GB

4,000MB = 4GB

50KB = 0.00005GB

Thus, 2TB is the largest. As described in the CompTIA ITF+ FC0-U71 Study Guide:

“Data storage capacity is measured using standard units such as KB, MB, GB, and TB, where 1TB = 1,000GB.”

A char (character) represents a single letter, number, or symbol. It differs from a string, which is a sequence of characters.

“The char data type stores a single alphanumeric character or symbol.” — CompTIA ITF+ Programming Fundamentals

Correct answer: C

Changing the router ' s password (particularly the Wi-Fi password) prevents unauthorized users from reconnecting to the network. It’s the most immediate and effective response.

“One of the most effective ways to secure a wireless network is by changing the default and existing passwords to prevent unauthorized access.” — CompTIA ITF+ Security Topics

Calling support may help but doesn’t address the issue directly.

Decreasing signal range may reduce but not eliminate access.

Resetting the router is more disruptive and unnecessary if the password can be changed.

Correct answer: C

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

“A router is a highly intelligent network connectivity device that can connect multiple network types to each other. Routers use routing tables to store network addresses and route packets based on the best path available.”

It further clarifies:

“Wireless routers are common in homes and offices. Functionally, wireless routers work just like their wired cousins.”

The default gateway in a home network is the router, as it serves as the device that connects the internal local area network (LAN) to the external Internet.
