This question is correct. There are three different conversions here. You can convert to the decimal or to the DSCP or to the class selector. In converting to the decimal you only use 6 bits and you keep the 6 bits from the left (the most significant bits). So taking the first one: 10111000. They give you 8 places and you keep the left most 6 bits giving you 101110. This is decimal 46. The DSCP is EF.
The second one they give you: 01010000 which is 8 bits. You keep the left most 6 bits and you have: 010100. In decimal this is 20. Now to convert to DSCP instead of totaling up all the bits you split them down the middle to get 010 100. Now you drop the right most bit for DSCP calculations so you have 010 10. The 010 gives you the Class Selector of 2 … the 10 gives you the drop probability of 2. So you have AF22.
The third: 1110000. Here they only give you 7 but it doesn’t matter. You take the left most 6 and get 111000. This is 56 decimal. For DSCP: 111 000 => 111 00 => CS 7
The fourth: 01101000 => 011010 => Decimal 26 => 011 01 => CS 3 DP 1 => AF31
The fifth: 00111000 => 001110 => Decimal 14 => 001 11 => CS 1 DP 3 => AF13
The sixth: 10011000 => 100110 => Decimal 38 => 100 11 => CS 4 DP 3 => AF43
