Explanation: Check Point's SecureXL technology, which is responsible for acceleration, has certain limitations and conditions under which acceleration may not occur. In this context, the question is asking about factors that will NOT affect acceleration.
Option B, "A 5-tuple match," will not affect acceleration. A 5-tuple match refers to the matching of source IP, source port, destination IP, destination port, and protocol. SecureXL can accelerate traffic that matches these criteria, but it's not a factor that hinders acceleration.
Options A, C, and D can all affect acceleration:
Option A mentions "Connections destined to or originated from the Security gateway," which implies that SecureXL acceleration can apply to these connections.
Option C mentions "Multicast packets," and SecureXL may have limitations in handling multicast traffic efficiently.
Option D mentions "Connections that have a Handler (ICMP, FTP, H.323, etc.)," and certain protocols (such as FTP) may require special handling and might not be fully accelerated by SecureXL.
