Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 407

What is a feature of a MAC address?

Answer options

• A. It consists of 38 bits.
• B. It consists of 12 hexadecimal numbers.
• C. It consists of 6 hexadecimal numbers.
• D. It consists of 24 bits.

Correct answer: B

Explanation

The correct answer is B because a MAC address is represented as 12 hexadecimal digits, which corresponds to 48 bits. Option A is incorrect as it states 38 bits, which is not accurate for a MAC address. Option C is incorrect because while a MAC address uses 6 pairs of hexadecimal digits, it is not just 6 hexadecimal numbers. Option D is wrong as a MAC address is not 24 bits; it contains 48 bits.
