AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 261

What number does the binary number 11000000 correspond to?

Answer options

• A. 128
• B. 192
• C. 64
• D. 117

Correct answer: B

Explanation

The binary number 11000000 converts to decimal as follows: 1*2^7 + 1*2^6 + 0*2^5 + 0*2^4 + 0*2^3 + 0*2^2 + 0*2^1 + 0*2^0, which equals 128 + 64 = 192. The other options do not correctly represent the binary value; 128, 64, and 117 do not match the calculated decimal result.
