Answer:
UDP checksum is 16 bit so we arrange our data in 16 bit pieces.
0 1 1 1 0 0 1 1 0 0 1 1 1 0 0 1
+ 0 0 0 1 1 1 0 0 1 0 1 0 1 1 0 0
-------------------------------------------------
= 1 0 0 0 1 1 1 1 1 1 1 0 0 1 0 1
= 0 1 1 1 0 0 0 0 0 0 0 1 1 0 1 0 ...... (Ones complement)
Checksum = 0 1 1 1 0 0 0 0 0 0 0 1 1 0 1 0

UDP and TCP use 1s complement for their checksum. Suppose you have the following two 8-bit bytes: 0101, 1010. What is the 1s complement of the sum of these 8-bit bytes? Suppose the two bytes are altered during transmission with the checksum as follows: 1001, 0110. Can the checksum be used to detect the alteration?

18. Computing an Internet checksum Consider the two 16-bit words (shown in binary) below. Recall that to compute the Internet checksum of a set of 16-bit words, we compute the one's complement sum [1] of the two words. That is, we add the two numbers together, making sure that any carry into the 17th bit of this initial sum is added back into the I's place of the resulting sum); we then take the one's complement of the result. Compute...
