CompTIA Exam N10-008 Topic 1 Question 64 Discussion

During the TCP three-way handshake process, the following fields are negotiated:

A . Sequence number: Initial sequence numbers are established during the handshake to keep track of the segments in the communication.

C . Window size: This determines the amount of data that can be sent before receiving an acknowledgment.

G . Acknowledgment number: This confirms receipt of the data and also indicates the next expected byte.

The other options are not negotiated during the three-way handshake:

B . MTU (Maximum Transmission Unit): This is determined at the network layer and is not negotiated during the handshake.

D . MSS (Maximum Segment Size): This is communicated during the handshake but not negotiated; it's declared by the sender to inform the receiver of the maximum segment size it can handle.

E . TTL (Time To Live): This is set in each IP packet to limit its lifespan and is not negotiated during the handshake.

F- Flags: Specific flags are used during the handshake (SYN and ACK), but they are not ''negotiated'' per se.

H) CRC (Cyclic Redundancy Check): This is used for error-checking in frames at the data link layer and is not part of the three-way handshake.
