You are hired by XYZ corporation to improve the efficiency and reliability of their current network. Based on the information given below , your team should make 3 recommendations to improve their network.

The following is a short list (not complete) of the details you recorded during your audit.

XYZ has 1500 employees spread over 2 adjacent 4 story buildings built in 1984. The wiring in the building (and between the two buildings) is cat5.

The backbone segment run between buildings is 212 feet.

Each building is 4500 square feet per floor.

The wireless LAN on the fourth floor of building two is supported by two wireless 802.11g routers only.

The devices used in the local area network are a mixture of 10/100 switches and hubs.

The second floor of building one is networked by two 24 port hubs.

Someone on the fourth floor of building one has installed their own wireless router.

The second floor of building two has 3 24 port switches with one router wired between switches 3 and 4. Switch 4 is the one connected to the backbone for that floor.

The following information came from capturing packets on the XYZ network with wireshark.

(be sure to support your recommendations)

• read the given scenario and answer the following questions:
• Need to provide 3 main problems that you see.

Starting a Packet Capture 3. Click Start, All Programs, Wireshark, Wireshark. 4. From the Wireshark menu bar, click Capture, Interfaces. 5. In the "Wireshark: Capture Interfaces" box, find the Interface with an IP address starting with 192.168.1. In the example as shown below on this page, it's the top one. This interface should show some packets passing through it, because it's connected to the network. Click the Start button in that interface's line.
