Given the following network: 192.168.10.0/24. Subnet this network with a /25 subnet mask. Answer the following questions: What is the class of the 192.168.10.0/24? Using/25, how many networks are available? Using/25, how many valid hosts per network are available? Using/25, what is the subnet mask? Using/25, what is the broadcast address?
21.) Consider the following configuration. Computer “A” IP address: 172.16.100.100 Subnet mask: 255.255.0.0 Computer “B” IP address: 172.16.200.200 Subnet mask: /16 What should be done to allow these computers to send and receive data to and from each other? A.) Nothing needs to be changed. B.) Delete the subnet mask from each computer. C.) A router must be configured and placed between the two computers. D.) Remove the hub between the two computers and replace it with a switch.
consider 3 hosts (A , B and C) where A is running 3-TCP process, B has 1-TCP process and C is running 2-UDP process all process are trying to connect to a web server to download a file . How many new socket(s) will be created at the server side? Explain why?
Can you find any problem with the following statement? "In a network (let Network Address 101.10.0.0/25 is using for 120 hosts network) a station is configured with an address of 10.0.0.11 Mask of 255.255.254.0 and a gateway address of 10.10.0.39."
Consider the LAN below consisting of 12 computers (A-L) connected by two Ethernet bridges. At t=0 the bridging table entries for both bridges are empty. At t = 1, node L sends to node E, and node E replies immediately (well before the next time step). What are the (MAC address, interface) entries in the bridging tables right after these transmissions? Note: interface = port number a) Left-hand-side bridge: (L,15), (E, 8). Right-hand-side bridge: (L,7), (E, 5). b) Left-hand-side bridge: (L,8), (E, 8). Right-hand-side bridge: (L,7), (E, 7). c) Left-hand-side bridge: (L,15), (E,5). Right-hand-side bridge: (L,7), (E, 8). d) Left-hand-side bridge: (L,8), (E,8). Right-hand-side bridge: (L,7), (E, 7).
. Assume: Your laptop's Ethernet address is 0a:0b:0c:0d:0e:0f, DHCP server address is 131.111.7.3, your IPv4 address will be 131.111.7.121, the gateway's IP address is 131.111.7.1, and Ethernet address is 00:01:02:03:04:05, the network subnet mask is 255.255.255.0.Write the series of protocol/packet exchanges that occur on the wired Ethernet link, up until you can send a single packet to 128.232.0.20. You do not need to describe packets after this packet has left the link. Include ARP and DHCP
Let's say Host C is a Web server that listens on port 80. Assume that this web server allows persistent connections and that it accepts requests from hosts A and B. Is Host C using the same socket to transmit each request? If they're broadcast over different sockets, do they both have port 80? You should talk about it and provide an explanation.
Assume that you have two computers and a router (default gateway) that have the following TCP/IP configuration and that Computer A wants to send data to Computer E. Match the addresses that will be used in the IP packet and the ethernet frame sent from Computer A.

Determine which among these stations can communicate with eachother. You need to show all detailed workings.
QUESTION 19 Suppose a process in Host C has a UDP socket with port number 4320. Suppose both Host A and Host B each send a UDP segment to Host C with destination port number 4320. Then both of these segments will be directed to the same socket with port number 4320 at Host C True False QUESTION 20 With TCP’s flow control mechanism, where the receiver tells the sender how much free buffer space it has (and the sender always limits the amount of outstanding, unACKed, in-flight data to less than this amount), it is not possible for the sender to send more data than the receiver has room to buffer. True False
