During your packet capture of traffic to check if your network is getting hit by a Denial of Service
attack, you analyze TCP headers. You notice there are many headers that seem to have the same
SEQ number, with the responding computer using different SEQ and ACK numbers in response. If
you are analyzing a normal three-way handshake between two Windows Server 2003 nodes, and
the first packet has a SEQ of 0xBD90FBFF, what will the responding computer use as an ACK?

A.
0xBD90FBFE

B.
0xBD90FB00

C.
1xBD90FBFE

D.
0xBD90FC00

E.
1xBD90FC00
