CompTIA ITF+ (FC0-U61) — Question 58

In a mobile phone, which of the following wireless technologies is MOST likely to provide Internet connectivity?

Answer options

• A. RF
• B. IR
• C. VPN
• D. NFC

Correct answer: A

Explanation

RF (Radio Frequency) technology is primarily used for wireless communication and is essential for connecting to cellular networks and Wi-Fi, which provide Internet access. IR (Infrared) is mainly used for short-range communication and cannot connect to the Internet. VPN (Virtual Private Network) is a secure connection method but does not provide connectivity by itself, and NFC (Near Field Communication) is used for very short-range communication, not for Internet connectivity.
