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?

The correct answer is B. Applying commands in a firewall policy determines the largest payload a device can handle in. 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…

  • BApplying commands in a firewall policy determines the largest payload a device can handle in

Explanation

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 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.
