Answer: (a) connection-less network layer protocol. The header is 20 to 60 bytes in length and contains information essential to routing and delivery. Multiple Choice Questions MCQ … IP version 4 (IPv4) uses Broadcasting for transferring packets from one computer to all computers; this probably generates problems sometimes. Because an IPv4 datagram can contain a variable number of options (which are included in the IPv4 datagram header) the 4 bits used by the header length are needed to determine where in the IP datagram the data actually begins. IPv4 Header is the header of IP datagram. It is customary in TCP/IP to show the header in 4-byte sections. TTL are used so that datagrams are not delivered and discarded automatically. IPv4 addresses are written in the dot-decimal notation, which comprises of four octets of the address expressed individually in decimal and separated by periods, for instance, 192.168.1.5. This set of interview questions on the network layer includes collections of interview questions on the fundamentals of the network layer in the OSI model. You want to get access to a router which is in Japan and you are in Luton. In this case, router discards the datagram. IPv4 header contains the necessary information required during transmission. D. None of these. 5. IPv6 is the next generation of IP addresses. In a datagram network, each packet is treated independently of all others. This field helps the network layer to understand, which data belongs to which protocol. How many option bytes are present? IPv4 uses 32-bit (4 byte) addressing, which gives 2 32 addresses. encapsulated in ...

It still routes … IPv4 was the first version deployed for production on SATNET in 1982 and on the ARPANET in January 1983. Practice these MCQ questions and answers for preparation of various competitive and entrance exams. B. IPV4. This ensures that the world won’t run out of IP addresses. It checks by decrementing the value to 1 till it reaches 0. In this case, router transmits the datagram without any fragmentation. 1. It measures the no.of.routers can datagram pass through. IPv4 Datagram Header Size of the header is 20 to 60 bytes. 4. Protocol: This IPv4 header is reserved to denote that internet protocol is used in the latter portion of the Datagram… Packets in the IPv4 layer are called datagrams. A datagram is a variable-length packet consisting of two parts: header and data. c. The IPv4 node has only stateful auto-configuration while the IPv6 node has both a stateful and a stateless address auto-configuration. 3. In IPV4 source and destination address is 128 bits while in IPv6 it is 32 bits. The IPv4 is a 32-bit address, whereas IPv6 is a 128-bit hexadecimal address. Accepted B. Discarded C. Interpreted incorrectly D. Answer (C) In class C, 8 bits are reserved for Host Id and 24 bits are reserved for Network Id. Then, addition of 20 bytes for an IPv4 header equals the size of the original IPv4 datagram (4440 + 680 + 20 = 5140) as shown in the images. Which is the best method to use in accessing Japan’s Cisco router? 2. But first 3 bits are fixed as 110 so we can use only (24 - 3) = 21 bits to create networks; hence total number of networks possible is 2 21. Physical Layer ... ipv4, ipv6 and its comparison, p2p applications, icmp, transition from ipv4 to ipv6, analyzing and designing … IPv4 short for Internet Protocol Version 4 is one of the popularly used IP versions. www.gtu-mcq.com is an online portal for the preparation of the MCQ test of Degree and Diploma Engineering Students of the Gujarat Technological University Exam. The value of HLEN in an IPv4 datagram is 15. Multiple choice questions on Networking topic Network Layer Protocols. Case-02: Size of the datagram is found to be greater than MTU and DF bit set to 1. For this reason, UDP sometimes is referred to as Unreliable Datagram … Before learning IPv6 datagram header and fields, I recommend you to learn IPv4 datagram header the different fields in IPv4 datagram header also.. IPv6 Datagram Packet Structure. Q. "In the version field of IPv4 header, when the machine is using some other version of IPv4 then the datagram is" Multiple Choice Questions (MCQ) on ipv4 connectivity with choices discarded, accepted, interpreted, and interpreted … For class C address, size of network id is 24 bits. Every time a datagram is processed its TTL value is decreased by one second. IPv4 Header Format consists of several fields as shown in the diagram. When the IP layer of a receiving host receives a datagram, ….. A. delivery is complete B. a transport layer protocol takes over C. a header is added A. IPV5. Answer & Solution Discuss in Board Save for Later 42. Datagram . The IPv4 address is written in hexadecimal value while the IPv6 address is written by dotted-decimal notation. Now, every … This section of our 1000+ Computer Networks MCQs focuses transport layer.

Explanation: 128.64.0.0 is correct IPv4 address because IPv4 is a standard numbering system that uses four integers from 0 to 255. C. IPV6. Datagram gets discarded when it reaches zero. Header Checksum d. Now, let us discuss the changes by analysing the IPv6 datagram format : Expanded addressing capabilities IPv6 increases the size of the IP address from 32 to 128 bits. IPv4 addresses are written in the dot-decimal notation, which comprises of four octets of the address expressed individually in decimal and separated by periods, for instance, 192.168.1.5. The "Total Length" in IPv4 header is a 16-bit field which identifies the length (in bytes), of the IPv4 datagram.Total Length includes the length of IPv4 header and the Data it carries.
