The Binary cheat sheet might be helpful!!!
Two points each. Given each host/netmask, answer with the network address of the network the host is on and the directed broadcast for the network. 1. 192.200.152.50/18 2. 61.80.64.200/28 3. 130.131.32.80/13 4. 80.66.240.186/30 Given a station with 4 interfaces: Interface name Address and netmask Ethernet0 128.227.209.250/24 Ethernet1 128.227.212.1/22 Ethernet2 128.227.208.80/26 Ethernet3 128.227.211.1/23 And a routing table of Network netmask nexthop 128.227.208.128 255.255.255.128 128.227.215.250 128.227.208.0 255.255.255.192 128.227.208.126 defaultroute 128.227.210.254 5. Which interface would a packet destined for 128.227.208.161 go out a) Ethernet0 b) Ethernet1 c) Ethernet2 d) Ethernet3 6. Which interface would a packet destined for 128.227.100.1 go out a) Ethernet0 b) Ethernet1 c) Ethernet2 d) Ethernet3 7. Which interface would a packet destined for 128.227.208.40 go out a) Ethernet0 b) Ethernet1 c) Ethernet2 d) Ethernet3 8. Which interface would a packet destined for 128.227.209.50 go out a) Ethernet0 b) Ethernet1 c) Ethernet2 d) Ethernet3 For questions 9 and 10 you have a network 128.64.96.0/20 and you want to subnet it. 9. If you wanted to subnet 128.64.96.0/20 into 4 networks of 1024 addresses (each supporting 1022 hosts) what would the the 4 sub-network addresses be? I'm looking for 4 subnets specified as XX.XX.XX.XX/YY. 10. If you wanted to further subnet only ONE of the 4 networks above into networks of 64 address (supporting 62 hosts) what would the new netmask be? How many sub-networks would you create?
