Which acceleration feature for RouterOS handles established connections to increase throughput?

• A. FastTrack
• B. Connection Tracking
• C. Mangle
• D. Queues

Answer: (A)

FastTrack creates a fast-path for established and related connections, letting those packets skip much of the normal firewall/NAT processing. By avoiding per-packet inspection in the common data path, the device can handle more traffic with the same CPU, boosting throughput for active flows. This is exactly what the question targets: accelerating established connections to raise throughput. Connection Tracking, while essential for keeping state and enforcing rules, adds processing overhead and doesn’t by itself provide the throughput boost. Mangle is used to mark packets for policy routing or different handling, not to accelerate established flows. Queues control how packets are scheduled and transmitted, which affects latency and overall throughput, but they don’t specifically implement the established-connection fast-path that increases throughput.
