$2)$ You have been hired as a Network Analyst for $\backslash ($ A B C $\backslash )$ Corp. ABCorp has a single site located in Sylvania, Ohio, with $62$ devices on an Ethernet network. Your job is to link ABCorp's existing network to the Intemet.

The internal IP network number scheme is $\backslash (10\mathrm{.}18\mathrm{.}40\mathrm{.}0/24\backslash ),$ and it cannot be changed.

When ABCorp originally installed the network, IP address $10\mathrm{.}18\mathrm{.}40\mathrm{.}1$ was reserved for the "Internet router" $($The "Internet router" has not yet been purchased$).$

ABCorp would like to use their internal Windows Exchange Server as their inbound SMTP mail server. The IP address of the Exchange Server is $10\mathrm{.}18\mathrm{.}40.205.$

ABCorp would also like to connect their internal WEB site to the internet via an IIS Server which has an IP address of $10\mathrm{.}18\mathrm{.}40\mathrm{.}210.$

ABCorp is unsure of how to obtain an Internet connection and which items to purchase.

a$.$ Discuss the various methods by which ABCorp might connect to the Internet $($both physical and logical connections$).$ Make a judgment about which physical and logical method$($s$)$ might be best for ABCORP and explain all Security measures you would recommend to ABCorp. Justify your answer. $(6$ points$)$

b$.$ Based on the method and security measures selected above, identify the equipment $($in complete detail$)$ ABCorp would have to purchase to connect to the Internet $($assume only CISCO network equipment$).(5$ points$)$

c$.$ Produce a working configuration file for ABCorp's router. This configuration file must accomplish the needs of ABCorp. using the method$($s$)$ and equipment selected in $($a$)$ and $($b$)$ above. $(8$ points$)$

d$.$ SSK Software $($from question $1$ above$)$ has entered into a long$-$term Software support contract with ABCorp. To completely and$/$or timely support the needs of ABCorp. SSK Software would like to inter$-$connect the two networks from its Toledo location via a CISCO router $($connect SSK Software's network with ABCorp's network$)$

Using the network layout, you selected for SSK Software in question $1($b$)$

Using information and methods obtained from this CSET$4750$ class.

i$.$ Propose a physical and logical plan to inter$-$connect the two networks without changing either company's network numbering scheme. Include $($in detail$)$ any equipment either company would need to purchase to accomplish the plan. $(4$ points$)$

ii$.$ ABCorp would like to limit SSK Software's remote access onto its network. What entries would need to be configured in order to limit SSK Software's remote access onto ABCorp's network to just two PCs at the same time, using only protocols TCP and$/$or RDP for remote support? $(4$ points$)$

SSK Sottware Corporation has opened offices in Chicago, Napoleon, Nashville, and Toledo. The corporate

headquarters are in Toledo. Toledo will serve as the hub for the network, CISCO routers will be wed at each

location. The network has no Intemet connection, and the company has no plans to add one.

Woekstation requircments at each of the locations are as follows:

b$.$ IP Network Number Scheme

Let's select Optlon $1($VLSM$),$ which efficiently uses IP addresses, and apply it to the

network design.

Toledo $($Headquarters$)$: $10\mathrm{.}0\mathrm{.}0\mathrm{.}0/26$

Chleago: $10\mathrm{.}0\mathrm{.}0\mathrm{.}64/27$

Napoleon: $10\mathrm{.}0\mathrm{.}0\mathrm{.}96/27$

Nashville: $10\mathrm{.}0\mathrm{.}0\mathrm{.}128/27$

Toledo $($Headquarters$)$:

Router: $10\mathrm{.}0\mathrm{.}0\mathrm{.}1$

Workstations: $10\mathrm{.}0\mathrm{.}0\mathrm{.}2-10\mathrm{.}0\mathrm{.}0\mathrm{.}50$

Printer: $10\mathrm{.}0\mathrm{.}0\mathrm{.}51$

Server: $10\mathrm{.}0\mathrm{.}0\mathrm{.}52$

Chleago:

Workstations: $10\mathrm{.}0\mathrm{.}0\mathrm{.}130-10\mathrm{.}0\mathrm{.}0\mathrm{.}158$

the third picture is my ssk software question $1$b network layout

I want you do this whole question in detail.
