Internet Firewall Firewall Layer 3 Device Active Router Layer 3 Device Active Router Load Balancer Web Server A Web Server B Power Supply A Power Supply A Power Supply B Power Supply B Generator UPS A UPS B

Okay, i've been doing this for a while and thought I'd help out the community b/c (in my opinion) if you take the selected answer, you'll get this wrong. You have to balance out real world experience with what is actually covered in the Security+ material. Since this is focusing on Web servers, forget anything about SAN. Also, this is not cloud so forget CSP. I could be wrong but Security+ doesn't cover SONET at all so ignore that as well. It's easier if you work your way up from the bottom so let's do that and you'll see the logic. Here is the flow: Utility ↓ Generator ↓ UPS A → Power Supply A (Web Server 1) → Power Supply A (Web Server 2) UPS B → Power Supply B (Web Server 1) → Power Supply B (Web Server 2) Web Server NICs ↓ Layer 3 Device ↓ Load Balancers ↓ Active-Active Firewalls ↓ Active-Active Routers (two paths) ↓ ISPs (two paths) ↓ Internet

Internet > ISP & ISP > Active-Active Firewall & Active-Active Firewall > Active-Active Routers > Layer 3 Device > Load Balancers > Power Supply A & Power Supply B / Power Supply A & B > UPS A & UPS B > Generator

i think this is a better view:Internet ISP - ISP - 2 leased lines Active Firewall – Active Firewall - to filter traffic Active-active Router - main router Active-passive router -backup router Load Balancer - to balance traffic Web Server A Web Server B Power Supply A Power Supply B - different power supply for redundancy Power Supply A Power Supply B - same Generator UPS A UPS B - different usp for redundancy

1.active/active router 2. active/standby router x3 3. Load Balancer 4.Web Server A Web Server B 5.UPS A/UPS B Generator. Firewall has nothing to do with making network not fail.

I think I solved it, Using the OSI Model to position everything. Going to start from Internet going following down the lines. (Both lines will be the same answer since it going to follow to one line into the data center. From Internet >> Load Balancers >> Active-Active Firewall >> IPS >> Active Active Routers >> Layer 3 devices (Level 3 Switch) >> NIC (going to 2 different web servers A & B) || The 2 Web A&B servers going to have an SAN component & a Cloud Service Provider. Example how its going to look in the boxes [SAN] [Cloud Service Provider] [SAN] [Cloud Service Provider]. Next its going to connect to an UPS A for web server A and UPS B for web server B. And the last box connecting to the 2 UPS is an Generator.

Does anyone have a link to a Diagram of the correct answer?

Internet | v Load Balancers | v Cloud Service Provider |-----------------------| v v Active-Active Firewalls Layer 4 Firewall | v Datacenter |-----------------------| v v UPS A / Power Supply B Generator | v Active-Active Routers | v Server Supply A / B | v Proxy | v SOVIET Ring | v Layer 3 Device
