A. Class C network address of 210.10.11.0/24 with no subnetting. Design two subnets for the above network A and network B using classful subnetting. Network A has requirement of 60 computers and Network B has requirement of 30 computers. Network-A connected to router interface G0/0 and network-B connected to router G0/1 interface. Show the steps of calculation. B. classless subnetting.

Can you please explain why these are the answers to this problem. I don’t get how to calculate the number of addresses for the interface please tell me how I do that .

Question 7: An ISP has the following block of addresses 132.204.192/20. The manager of this ISP hired you to help him assign IP block of addresses to the following subnets. • Subnet A should have enough addresses to support at least 850 interfaces; • Subnet B should have enough addresses to support at least 55 interfaces; • Subnet C should have enough addresses to support at least 46 interfaces; • Subnet D should have enough addresses to support at least 40 interfaces; • Subnet E should have enough addresses to support at least 20 interfaces. • Subnet F should have enough addresses to support at least 28 interfaces. Give the range of addresses (in binary) assigned to each subnet. Show your work.

Suppose that a router interconnects three subnets, where all the interfaces ofthe subnets must have the prefix 164.132.62/24. Also, suppose that Subnet 1 is required to support up to 60 interfaces, Subnet 2 is required to support up to 100 interfaces, and Subnet 3 is required to support up to 15 interfaces. Provide three network addresses of the form a.b.c.d/x that satisfy the aboverequirements.

Implement in Packet Tracer a network of a fictitious organization with the following characteristics: - The organization will be made up of 4 units: 3 local Ethernet networks + 1 remote Ethernet network (via the Internet)- Local dependencies must connect to each other through a Backbone (links) between Switches- There must be 2 VLANs in 2 local dependencies- Throughout the organization there must be 2 IP networks with 2 subnets each. The different IP networks must communicate with each other.- A static routing method or a dynamic routing method must exist- The remote unit must be integrated into some IP network through a VPN link- Each local office must have IP telephony (VoIP). At least one IP phone for each unit.- In each unit there must be at least 5 user PCs- Each PC must have Automatic IP configuration (DHCP)- DHCP, DNS and Web Servers must exist - All rooms must have access to the Internet through NAT-PAT- There must be a Wi-FI network in each unit

. The following is configured on a router Router(config)# interface g0/0.10 Router(config-subif)# encapsulation dot 1Q 20 Router(config-subif)# ip address 192.168.30.1 255.255.255.0 A packet is sent from the router out the subinterface to a trunk port on a switch. The switch will treat the packet as if it is on what VLAN? The native VLAN VLAN 30 VLAN 10 VLAN 20

22. A datagram subnet allows routers to drop packets whenever they need to. The probability of a router discarding a packet is p. Consider the case of a source host connected to the source router, which is connected to the destination router, and then to the destination host. If either of the routers discards a packet, the source host eventually times out and tries again. If both host-router and router-router lines are counted as hops, what is the mean number of a. (a) hops a packet makes per transmission? b. (b) transmissions a packet makes? (c) hops required per received packet?
