Quizplus · Accepted Answer

We can simplify the expression by treating it as a hexadecimal number and converting it to binary. The first 8 digits (11ebf5ef) represent the first 4 bytes, and the next 4 bytes are represented by the next 8 digits (bbd8fa27, 95d1, 631851b1e5e8, TBX9354, and 11). When we convert it to binary, the last 8 digits of the first set (ef) equal 11101111 in binary. In the second set, we can ignore the TBX9354 and 11 because they are both 0 in binary. The remaining digits can be represented as 101110111101100010011110101000110100111010000011000101000100011100001101101111110011000101010000111000111101001101011001011. This is equivalent to 11ebf5ef_bbd8_fa29_95d1_ef582875b1b7_TBX9354_11, which matches choice B.
