171) When TCP intercept is enabled in its default mode, how does it react to a SYN request?
, \5 N! O' o3 ?; @A. It intercepts the SYN before it reaches the server and responds with a SYN-ACK B. It drops the connection
# z/ X% a; u4 ~+ e" i; |C. It monitors the attempted connection and drops it if it fails to establish within 30 seconds
D. It allows the connection without inspection
E. It monitors the sequence of SYN, SYN-ACK, and ACK messages until the connection is fully established

The default is intercept mode.  In intercept mode, the software actively intercepts each incoming connection request (SYN) and responds on behalf of the server with a SYN-ACK, then waits for an acknowledge (ACK) from the client. When the ACK is received, the original SYN is sent to the server and the software performs a three-way handshake with the server. When the three-way handshake is complete, the two half connections are joined.
