1. This set of Computer Networks Multiple Choice Questions & Answers (MCQs) focuses on “ICMP”.1. UDP(User Datagram Protocol)-Another well-known transport layer protocol. In computer networking, the User Datagram Protocol (UDP) is one of the core members of the Internet protocol suite.The protocol was designed by David P. Reed in 1980 and formally defined in RFC 768.With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network. Practice these MCQ questions and answers for preparation of various competitive and entrance exams. Internet Control Message Protocol (ICMP) has been designed to compensate _________3. On each addition, if a carry-out (17th bit) is produced, swing that 17th carry bit around and add it to the least significant bit of the running total.If the checksum calculation results in the value zero (all 16 bits 0) it should be sent as the one's complement (all 1s) as a zero-value checksum indicates no checksum has been calculated.When UDP runs over IPv4, the checksum is computed using a "pseudo header" that contains some of the same information from the real IPv4 header.The source and destination addresses are those in the IPv4 header. If using UDP, the end user applications must provide any necessary handshaking such as real time confirmation that the message has been received. In a simple echo-request message, the value of the sum is 01010000 01011100.
During error reporting, ICMP always reports error messages to ________4. Internet Control Message Protocol (ICMP) has been designed to compensate _____ a) Error-reporting b) Error-correction c) Host and management … Which IP option is used if exactly four specific routers are to be visited by the datagram> - strict source rout For the timestamp option, a flag value of______means that each visited router adds only the timestamp in the provided field. User Datagram Protocol (UDP) is a connectionless transport layer communication protocol used to establish low tolerating and loss latency connections for delivery of services or packets within or across the network.
During debugging, we can use the ____________ program to find if a host is alive and responding.11.
The protocol is that for UDP (see UDP checksum computation is optional for IPv4.
The source address is the one in the IPv6 header. The destination address is the final destination; if the IPv6 packet does not contain a Routing header, that will be the destination address in the IPv6 header; otherwise, at the originating node, it will be the address in the last element of the Routing header, and, at the receiving node, it will be the destination address in the IPv6 header. If a checksum is not used it should be set to the value zero.
1. ICMP error message will not be generated for a datagram having a special address such as _______6. In windows ____________ can be used to trace the route of the packet from the source to the destination.12.
When a router cannot route a datagram or host cannot deliver a datagram, the datagram is discarded and the router or the host sends a ____________ message back to the source host that initiated the datagram.7.
Which of these is not a type of error-reporting message?5. Both protocols help in to establish the connection and transfer data between two ends of the communication.
The source-quench message in ICMP was designed to add a kind of ____________ to the IP.8. The method used to compute the checksum is defined in In other words, all 16-bit words are summed using one's complement arithmetic. Answer (C) The Protocol Data Unit for Application layer in the Internet Stack (or TCP/IP) is called Message. © 2011-2020 Sanfoundry. These questions are very useful for interview and exam preparation. IP is _____ datagram protocol. A) datagram has not been fragmented B) datagram is 100 bytes in size C) the first byte of the datagram is byte 100 D) the first byte of the datagram is byte 800. 2) Which of the following transport layer protocolss is used to support electronic mail? Then, value of checksum is ___________ Multiple choice questions on Networking topic Network Layer Protocols.
