Certified Incident Handler (ECIH) — Question 24

Rickson, a security professional at an organization, was instructed to establish short-range communication between devices within a range of 10 cm. For this purpose, he used a mobile connection method that employs electromagnetic induction to enable communication between devices. The mobile connection method selected by Rickson can also read RFID tags and establish Bluetooth connections with nearby devices to exchange information such as images and contact lists.
Which of the following mobile connection methods has Rickson used in above scenario?

Answer options

• A. NFC
• B. Satcom
• C. Cellular communication
• D. ANT

Correct answer: A

Explanation

The correct answer is A, NFC, which stands for Near Field Communication and is specifically designed for short-range communication, typically up to 10 cm. The other options do not fit the requirements: Satcom is for satellite communication, Cellular communication covers wider ranges, and ANT is a low-power wireless protocol that does not specialize in such short-range interactions.
