Question

39. Regular session closing in TCP uses which of the following steps. (Select all that apply) a. Begins with one node (usually the originator of the communication) sending a FIN packet b. Second node sends an ACK to the first FIN packet c. Second node checks with its copy of the application that was communicating to determine if the application can perform a normal termination terminate, the second node sends a FIN packet node's FIN packet d. If the local second node application responds that it can e. First node sends a SYN AÇK in response to the second 40. UDP does not handle application message fragmentation Therefore the UDP Length field is 16 bits long to try to compensate with a User Data field of 65,536 bytes a. True b. False 41. DHCP reduces network staff effort by (Select only one) a. Temporarily assigning (leasing) IP addresses b. Displaying static IP addresses c. Encrypting static IP addresses d. Encrypting temporary IP addresses

Explanation / Answer

39.

Here are the steps that are followed to close a regular TCP session:

So only the options (a),(b),(d),(e) matches.

40. UDP has 8 bytes header. It contains source and destination port number , each of 16 bit size.

source port number: This is used by source host. It is 16 bit longs. So port numbers range between 0 to 65,535.

Destination port number: This is a port number used by Destination host. It is also 16 bits long and also same number of port range like source host.

length: Length field is a 16 bits field. It contains the total length of the user datagram, header and data. So, The option is a. True.

41. DHCP server on getting the message from the client, looks in the pool in order to find an IP address it can lease for the client. After that, it adds the MAC address information of the client and the IP address it will lease out to the ARP table.

So option (a) will work.
