In the TCP/IP protocol suite, which one of the following is NOT part of the IP header?
Answer: (d).Destination port number
Suppose that the maximum transmit window size for a TCP connection is 12000 bytes. Each packet consists of 2000 bytes. At some point of time, the connection is in slow-start phase with a current transmit window of 4000 bytes. Subsequently, the transmitter receives two acknowledgements. Assume that no packets are lost and there are no time-outs. What is the maximum possible value of the current transmit window?
Answer: (b).8000 bytes
Answer: (a).By progressively querying routers about the next router on the path to B using ICMP packets, starting with the first router
Answer: (b).distance vector routing protocol
In a communication network, a packet of length L bits takes link L1 with a probability of p1or link L2 with a probability of p2. Link L1 and L2 have bit error probability of b1 and b2 respectively. The probability that the packet will be received without error via either L1 or L2 is
Answer: (a).(1 - b1)Lp1 + (1 - b2)Lp2
Answer: (d).
Assume that "host1.mydomain.dom" has an IP address of Which of the following options would be most appropriate as a subsequence of steps in performing the reverse lookup of In the following options "NS" is an abbreviation of "nameserver".
Answer: (c).Query a NS for and then a NS for domains
An IP datagram of size 1000 bytes arrives at a router. The router has to forward this packet on a link whose MTU (maximum transmission unit) is 100 bytes. Assume that the size of the IP header is 20 bytes. The number of fragments that the IP datagram will be divided into for transmission is :
Answer: (d).13
Answer: (c).Ethernet frame includes a CRC field and IP packet includes a checksum field
Two popular routing algorithms are Distance Vector(DV) and Link State (LS) routing. Which of the following are true?
(S1) Count to infinity is a problem only with DV and not LS routing
(S2) In LS, the shortest path algorithm is run only at one node
(S3) In DV, the shortest path algorithm is run only at one node
(S4) DV requires lesser number of network messages than LS
Answer: (d).S1 and S4 only
