a class B‚ so it has a default subnet mask of 255.255.0.0. Then you need to divide this network into 7 subnets and only the net work address 255.255.240.0 provides enough networks because it will provide 16 - 2 = 14 subnets (-1 for the network address and -1 for the broadcast address‚ which gives a -2 from the total of subnets). #9 Answer: C Explanation: The network address 209.168.19.0‚ which was originally assigned is a class C address with a default subnet mask of 255.255.255.0. You then

Ethernet Task Index Task 1 - Create a subnet plan Task 2 - Assign addresses to all interfaces‚ including serial lines NYEDGE2 Gi0/0 Ethernet Task 3 - Configure the interfaces in each router Task 4 - Configure/enable IP RIP routing Task 5 - Confirm configuration and operation Task 1 - Create a subnet plan How many segments and users/segment do you need to accommodate? Step 1: Determine the correct subnet mask. Action: Develop a subnet plan based on the story and conditions. Result:

number can make all the difference in the way a network performs. In the case of the diagram E-1‚ there are many problems like this that can cause the network to not perform the way it is supposed to. Some of these problems include the IP addresses‚ subnet masks‚ and default gateways in this network. All of these things need to be correct and working together in order for the network to function properly. First‚ we must start with the problems with the network shown in the diagram. There are many

you assign the IP addresses to the various subnets? How would you control the process by which IP addresses are assigned to individual computers? You will have to make some assumptions to answer both questions‚ so be sure to state your assumptions. As a network manager‚ I would first try and see whether the addresses are already known/established and whether or not they are in the same subnet. If the addresses are known and they are in the same subnet: I would make the following assumptions: -Client

We use a logical view to define the logical paths of the service function chain. Figures 2 shows an example slice by comparing its physical view to its logical view as for SFCs.
