1. Complete both parts A and B of the question below.

(A) Based on the figure below, what is the WLAN topology in use? In what way does the ISM band impact the topology? What must be done to ensure proper coverage of voice and video applications in the network?

The graphic above is made up of three access points that terminate on a wired network. The access points are placed adjacent to each other, each in its respective coverage area.

(B) Assume that the organization is using WEP Personal with a 128-bit WEP key. Come up with an example hexadecimal WEP key that will work in this scenario. Justify your answer.

2. Complete all parts of the question below.

(A) Identify the switches that will become the root bridge in the topology below. Explain how you arrive at that conclusion.

The graphic above is made up of four Cisco 2960 switches connected in a ring topology. SW1 on the left connects to SW2 via a FastEthernet 0/1 interface on both sides. SW2 connects to SW3 via a FastEthernet 0/2 interface on both sides. SW3 connects to SW4 via a Gigabit Ethernet 0/1 interface on both sides. SW4 connects to SW1 via a Gigabit Ethernet 0/2 on both sides. SW3 connects to a Hub via both its FastEthernet 0/1 and 0/3 interfaces.

(B) Identify all the link costs. Assume default link costs.

(C) Identify the root ports in the diagram and the designated ports.

(D) What ports will be used as alternate (ALTN) or blocked ports? What ports will be used as backup ports? Please explain how you arrive at this conclusion.

(E) How many instances of STP are running on the switches if we only have five VLANs? Assume default configuration of the Cisco switches. Explain your answer.
