1st Lab: An AP connected to a WLC through a switch. There are two DHCP pools, one on the WLC and the other on the switch. The switch excludes the ranges of WLC DHCP pool from its pool. How can the clients get their IP address? (Choose two) A) Client will get its IP Address from the WLC.B) Client will get its IP Address from the switch. C) Client will get its IP Address from WLC & Switch ( Round robin between them ).D) Client can get Its IP statically. Answer: A, B

1st Scenario: An AP wasn't able to authenticate to WLC. AP on aVlan, WLC on another VLAN. The connected switch has the DHCP for both vlans.My answer: add DHCP option 43 hex "WLC IP in hexadecimal format" because the AP to take DHCP option 43 takes, and address of the WLC is the ip administration in hexadecimal.

2nd Scenario: AP, Switch and WLC. Two DHCP polls configured one on switch and one on WLC. The question was about how the client get the IP.My answer: Static IP for users, because the DHCP in WLC, and DHCP Server overlap, so do not give address.

3rd Scenario had 2 questions: They had shown config of AP, WLC and switch to look at and figure out the problem.My answers:(1) Wireless->802.11b/g (all the B Data Rates were disabled and old clients with only 802.11b weren't able to connect)(2) WLAN General Settings misconfigured (Radio Policy was on b/g only so 2.4Ghz just allowed, no 802.11n high data rate available)

1) Roundrobin method either wlc or switch will provide IP, clientcan be configured with static IP address. two answers2) WLAN general setting is not configured correctly (N clients issue), Security WPA2 were mapped to tkip (old b clients issue).3) Q1: Set AP TX power level to 4 (b/g/n radio currently set to level 5, changing it to 4 will increase by 3dBm) and Q2: What information will you see in the log? (select 4)A: emergencies, alerts, critical, errors

4) set the dhcp option 43 hex f1040a0a0a0a (10.10.10.10) for vlan 20 DHCP pool

Q1: Gives a scenario where an AP can't reach the controller. They are connected through a switch and the AP is on vlan 1 and the WLC is on vlan 20. The question asks which switch commands will allow the AP to reach the WLC. All deal with DHCP option 43 and you must determine which vlan to apply it to and whether to use hex and ascii. The answer I chose was vlan 1 and hex.Q2: Shows some WLAN, radio, and other configuration and first asks why clients cannot achieve full 802.11n rates. The WLAN is configured for WPA2/TKIP, so the answer I chose was improper security settings. Second part asks why some older 802.11b/g clients cannot connect. Answer is also security settings as the clients cannot handle WPA2/TKIP.Q3: DHCP scopes within the same network are configured on the WLC and on the switch. They do not overlap. Question asks about client IP address assignment behavior. First, DHCP is not required on the WLAN, so a client can configure a static address. This is the first answer. Second answer I chose was that DHCP requests will be fulfilled by the WLC and switch in a round robin fashion.

Below are the answers for labs I got:1) Roundrobin method either wlc or switch will provide IP, clientcan be configured with static IP address.2) WLAN general setting is not configured correctly (N clients issue), b/g/n networks not configured correctly (old b clients issue).3) Set AP TX power level to 4 (b/g/n radio currently set to level 5, changing it to 4 will increase by 3dBm)4) set the dhcp option 43 hex f1040a0a0a0a (10.10.10.10) for vlan 20 DHCP pool

1st Scenario: An AP wasn't able to authenticate to WLC. AP on aVlan, WLC on another VLAN.

Two DHCP polls configured one on switch and one on WLC. The question was about how the client get the IP. My answer: round

robin between the two DHCP.3rd Scenario had 2 questions: They had shown config of AP, WLC and switch to look at and figure out the problem.My answers:(1) Wireless->802.11b/g (allthe B Data Rates were disabled and old clients with only 802.11b weren't able to connect)(2) WLAN General Settings misconfigured (Radio Policy was on b/g only so 2.4Ghz just allowed, no 802.11n high data rate available)

1.- old laptops cann't connect to networkA= all b (DSSS) speed where disable, 1 2 5.5 y 11 where disable.

2.- SW has a dhcp pool for vlan X from 10.10.X.0/24 from 10.10.X.128-254WLC has a SSID wich use DHCP server from 10.10.X.11 - 10.10.X.127, DHCP override is not selected on WLAN config, also the Management interface is in the network 10.10.X.0 using last octect 2,the question was Who deliver DHCP to the clients(choose two). and the option where like:the client received from swthe client received from wlcthe client dont received ip because overlappingthe client received from wlc with a round robin scenario

1. First one was about the DHCP troubleshooting and answer to this question was "DHCP option 43 hex f1040a0a0a0a for vlan 20 DHCP pool"

2. The question was: What power level should be set on the WLC to increase the power by 3dB for 2.4 GHz frequency band. The current power level set was 5. So the DESIRED power level would be 4 (1 being the max and 7 being the least). Be careful: Both 2.4 and 5 Ghz WLC screenshots were shown so concentrate on 2.4 Ghz. only.

3. WLC and switch both were providing DHCP service and the question was which would provide the IP addresses. Answer to the questions is : a) Both WLC and Switch would provide IP addresses in a Round-Robin fashion. b) APs can be assigned static IP addresses.

4. Question was why old 2.4 Ghz clients and clients using N-

adapter were not able to associate to network : Can't remeber the answers.
