Which statement best describes MBF behavior on Citrix ADC?

• A. It eliminates ARP lookups entirely
• B. It avoids asymmetrical packet flows and multiple route lookups
• C. It forwards only Layer 2 traffic
• D. It disables TLS renegotiation

Answer: (B)

MBF ensures that a given flow uses a single, consistent path across multiple possible routes, so the return traffic follows the same path as the request. This binding of a flow to one exit path prevents packets from taking different routes in each direction, which would create asymmetric routing and trouble for stateful processing along the way.

By establishing this path once and reusing it for the entire flow, MBF also reduces the number of route lookups the device has to perform, which lowers CPU overhead and improves throughput. The focus is on maintaining symmetric, efficient routing for each active connection rather than altering ARP behavior, restricting to Layer 2 traffic, or affecting TLS renegotiation.
