ccnp treasure trove- MSS

The Maximum Segment Size (MSS) of the TCP protocol is. a- responsible for determining the maximum size of packet headers. B- limited by MTU (Maximum Transmission Unit), such that MSS = MTU - (IP and TCP headers). c- a measurement that represents the largest data packet size that a network-connected device can accept, including headers. D- a Layer 2 metric of the TCP protocol.

Angenommen, ein Host überträgt eine TCP-basierte Anwendung, deren MSS auf der Ethernet-MTU basiert. Welche Größe in Bytes des MSS verhindert in diesem Fall eine Fragmentierung des IP-Datagramms, vorausgesetzt, dass die Optionsfelder TCP und IPv4 leer sind? hint: TCP hader: 20 bytes ipv4 header: 20 bytes ipv6 header: 40 bytes (fixed length). 1460. 1472. 1492. 1500. 1520.

In the TCP/IP architecture, some layers may stipulate the maximum size of what will be transmitted. At the transport layer, this is defined by the hint: MTU is the maximum size (in bytes) of a packet that can be transmitted over a specific network medium without requiring fragmentation. It includes the headers (IP, TCP/UDP) and payload. It's configured on the devices' interfaces. MSS is the maximum size of the data payload (Layer 4 segment) that a TCP connection can send in a single packet. It does not include the TCP or IP headers. Scope: It applies specifically to the TCP payload size. Calculation: MSS = MTU - (IP header size + TCP header size) For example: Ethernet MTU = 1500 bytes IP header = 20 bytes, TCP header = 20 bytes MSS = 1500 - 40 = 1460 bytes Configuration: MSS is negotiated during the TCP three-way handshake between devices. MSS. MTU.

Observe the capture below (captured by Ethereal). In this table, information in the format "XXX > YYY" indicates that XXX is the source TCP port and YYY is the destination TCP port. Considering the Table above, analyze the statements below. 1. In Line 1, the MSS indicates the maximum TCP segment size that Host 1 can handle. 2.The information in the 3 packets (Lines 1, 2 and 3) indicates that the connection between Host 1 and Host 2 has been terminated. 3. The HTTP packet shown in Line 4 indicates the receipt of an html page. Is(are) correct: statement 1 only. statement 2 only. statement 3 only. statements 1 and 2 only. statements 1, 2 and 3.

Regarding TCP/IP Architecture or Internet Architecture, select the correct alternative. a- In the TCP specification, it is indicated that TCP must send data that is in buffers, according to its own convenience, but the maximum amount of data that can be placed in a segment is limited by the MSS (Maximum Segment Size). B- The UDP Protocol is a Connection Oriented transport protocol. Thus, before an application process can start sending data to another process, the 2 processes must establish a connection. c= The IP Protocol (Internet Protocol) is a protocol responsible for converting a Physical Address (MAC) into an IP address, as well as converting an IP address into a Physical Address (MAC). D- Regardless of the type of Socket, UDP or TCP, both are identified by a tuple of 02 elements, that is, source IP address, source port number.
