SIMULATION -

A network administrator has been tasked with configuring a network for a new corporate office. The office consists of two buildings, separated by 50 feet with no physical connectivity. The configuration must meet the following requirements:

Devices in both buildings should be able to access the Internet.
Security insists that all Internet traffic be inspected before entering the network.
Desktops should not see traffic destined for other devices.


INSTRUCTIONS -

Select the appropriate network device for each location. If applicable, click on the magnifying glass next to any device which may require configuration updates and make any necessary changes.
Not all devices will be used, but all locations should be filled.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.

You can't have a Wireless Range Extender without a WAP for it to connect to and repeat. The device at the bottom middle needs to be a WAP. Then the device in Bldg B can be a wireless range extender. It's ok since all Bldg B devices appear to be wireless capable (laptops, phone)

Why not put the extender between buildings and the WAP inside?

Agree. Also with "...two buildings, separated by 50 feet with no physical connectivity.", I think the WAP will be connected to building A's switch physically so it gets inbound internet connection from wired ethernet. Then put a wireless range extender in building B.

But will they be able to access the company’s network resources with a wireless extender?

When they are separate devices, a firewall does not connect directly to the internet. I know that's what chatgpt is telling you, but it's wrong. Ask it if the firewall should be connected to the internet or the router, and it will tell you that it should be the router. The actual configuration--top down--is: [Internet] ↓ [Router] ← Connects to ISP, handles NAT & basic routing ↓ [Firewall] ← Inspects & filters all incoming/outgoing traffic ↓ [Internal LAN (Switches, WAPs, Endpoints)] = WAP between buildings and Wireless Extender in Building B. Don't get confused by logical diagrams that show a firewall protecting the edge/directly connected to the internet as some routers (like home routers) include a firewall. When they are separate devices, the router is what connects to the ISP/internet and the firewall sits inside to protect the inner private network.

Nevermind. Comptia apparently is focusing on "security at the edge" so traditional designs are no longer considered the best answer. Found a CompTIA graphic that shows this. So ... it should be firewall==>router==>switch. Man, I hate CompTIA.

Ok folks let’s start with the far left ?, that should be a switch…then let’s go all the way to the far right…that should be a range extender. Now let’s look at the three ??? In the middle starting with the top ? that should be a firewall…the middle ? should be a router, then the bottom? should be a WAP…there you have it.

• Building A: Switch • Connection between Building A and the Internet: Router • Connection to Internet: Firewall • Connection to Building B: WAP or Wireless Range Extender • Inside Building B: Switch (if wired) or use WAP
