2. As a newly hired network engineer, you are tasked to compute for addresses of a newly developed network. Use 129.152.224.0/22 to compute for the subnets using VLSM method. Fill up the information in this table Required Number of Host Number of Bits Borrowed New Subnet Mask Prefix Subnetwork Number of Host Created Waste Department A 100 Department B 60 Department C 10 Department D 4 Department E 12 Department F 30 Department G 55 Department H 10 Department I 8 Department J 15 Department K 25
An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all O's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network? Type your answer.
2. For each of the following, write the ONE correct answer. a) TCP/IP layers are Internet (I), Transport (T), Application (A), Physical (P), Network Interface (N). Which layer deals with modulation in WiFi networks? The layer whose header contains the source MAC address is Answer= Answer= b) The leftmost and rightmost bits in a byte are MSbit and LSbit respectively. For the 2 bytes 10000000 00000001, assume that the first byte is MSbyte and the second byte is LSByte. Assuming that bits are transmitted from left to right, write the transmission order that is bit big endian and byte little endian: Answer= c) Let TP=unshielded twisted pair, CC=coaxial cable, F=fiber, L=lasercommunication. Which of these media Uses a shield for limiting interference Achieves the highest bandwidth across long distances Answer= Answer= d) Of FDMA, CDMA, TDMA and SM (statistical multiplexing), which method is multiplexing primarily based on in LTE networks?

IPV4 address space? IPV6 address space? d) If a certain adapter wants to send a frame such that all other adapters on the same LAN will receive and process it (no adapter will reject it). What is the special MAC broadcast address that it inserts into the destination address field? Write it here:
