Packet acceleration (SecureXL) identifies connections by several attributes. Which of the attributes is NOT used for identifying connection?
The correct answer is C. TCP Acknowledgment Number. SecureXL identifies and accelerates connections using a standard 5-tuple of network attributes - the TCP Acknowledgment Number is a transport-layer sequencing field and is not part of connection identification.

Why each option
SecureXL identifies and accelerates connections using a standard 5-tuple of network attributes - the TCP Acknowledgment Number is a transport-layer sequencing field and is not part of connection identification.
Source Address is one of the five core attributes SecureXL uses to uniquely identify a connection in its acceleration table.
Destination Address is one of the five core attributes SecureXL uses to uniquely identify a connection in its acceleration table.
SecureXL classifies connections for hardware acceleration using the 5-tuple: source IP address, destination IP address, source port, destination port, and IP protocol. The TCP Acknowledgment Number is a sequence-tracking field used within an already-established TCP session to confirm received data, not a flow identifier used in SecureXL's connection table lookups.
Source Port is one of the five core attributes SecureXL uses to uniquely identify a connection in its acceleration table.
