CCNA v4 - E3 - Module 7
1. What will a wireless client transmit to discover the available WLAN networks?
probe request
2. Which function is provided by a wireless access point?
converts data from 802.11 to 802.3 frame encapsulation
3. Why is security so important in wireless networks?
Wireless networks broadcast data over a medium that allows easy access.
4. Refer to the exhibit. When configuring the wireless access point, which setting does the network administrator use to configure the unique identifier that client devices use to distinguish this wireless network from others?
Network Name (SSID)

Refer to the exhibit. The network administrator needs to setup Switch1 for remote access from HostA. The show ip interface brief is issued on Router1 and the show interfaces trunk command is issued on the
Switch1 to verify the current status. The administrator applies the additional configuration shown in the exhibit to Switch1. However, the telnet from HostA fails. What additional commands need to be applied
to the switch?
Switch(config)# interface vlan 1
Switch(config-if)# ip address 10.1.1.250 255.255.255.0
Switch(config-if)# no shutdown
Switch(config-if)# ip default-gateway 10.1.10.254
Switch(config)# interface vlan 1
Switch(config-if)# ip address 10.1.50.250 255.255.255.0
Switch(config-if)# no shutdown
Switch(config-if)# ip default-gateway 10.1.50.254
Switch(config)# interface vlan 10
Switch(config-if)# ip address 10.1.10.250 255.255.255.0
Switch(config-if)# no shutdown
Switch(config-if)# ip default-gateway 10.1.10.254
==> Switch(config)# interface vlan 10
Switch(config-if)# ip address 10.1.1.250 255.255.255.0
Switch(config-if)# no shutdown
Switch(config-if)# ip default-gateway 10.1.10.254
Switch(config)# interface vlan 50
Switch(config-if)# ip address 10.1.10.250 255.255.255.0
Switch(config-if)# no shutdown
Switch(config-if)# ip default-gateway 10.1.10.254

Refer to the exhibit. On the basis of the configuration shown, how will an Ethernet frame on port GigabitEthernet0/1 be modified?
802.1Q encapsulation prepends a 4-byte tag field in front of the original Ethernet frame and recomputes the frame check sequence (FCS) on the modified frame.
==> 802.1Q encapsulation inserts a 4-byte tag field into the original Ethernet frame between the source address and type/length fields and recomputes the frame check sequence (FCS) on the modified frame.
802.1Q encapsulation prepends an 802.1p field in front of the original Ethernet frame and recomputes the frame check sequence (FCS) on the modified frame.
