Exam FCSS_EFW_AD-7.6 Topic 3 Question 70 Discussion

Actual exam question for Fortinet's FCSS_EFW_AD-7.6 exam
Question #: 70
Topic #: 3
How will configuring set tcp-mss-sender and set tcp-mss-receiver in a firewall policy affect the size and handling of TCP packets in the network?

Suggested Answer: B Vote an answer

The set tcp-mss-sender and set tcp-mss-receiver commands in a firewall policy allow an administrator to adjust the Maximum Segment Size (MSS) of TCP packets.
This setting controls the largest payload size that a device can handle in a single TCP segment, ensuring that packets do not exceed the allowed MTU (Maximum Transmission Unit) along the network path.
set tcp-mss-sender adjusts the MSS value for outgoing TCP traffic. set tcp-mss-receiver adjusts the MSS value for incoming TCP traffic.
This helps prevent issues with fragmentation and MTU mismatches, improving network performance and avoiding retransmissions.
