QUESTION 261

A Cisco Unified Wireless Network client is configured with manual proxy settings. How can you, as an administrator, ensure that the user is able to authenticate and access the network by having the WLC respond to a client request with a web page that prompts the user to change the Internet proxy settings to automatically detect the proxy settings?

 

A.

Enable conditional redirect on the web authentication policy.

B.

Make sure that the option for web authentication proxy redirection port is set to 0.

C.

Make sure that the web authentication proxy redirection mode is enabled.

D.

Make sure that the web authentication proxy redirection mode is disabled.

 

Answer: C

 

 

QUESTION 262

Refer to the exhibit. A network administrator is configuring local WLC DHCP services. Which group of statements regarding the output in the exhibit and the client DHCP process is correct?

 

clip_image002

 

A.

DHCP proxy is enabled. The WLC has sent the client DHCP Discover out, but no DHCP Offer came back.

This indicates DHCP proxy needs to be disabled for local WLC DHCP service.

B.

DHCP proxy is disabled. The WLC has received a DHCP request from the client. As the capture does not

include an indication a DHCP ACK was received or not, this does not indicate a specific issue.

C.

DHCP proxy is disabled. The WLC has sent the client DHCP Discover out, but no DHCP Offer came back.

This indicates an apparent WLC issue.

D.

DHCP proxy is enabled. The client is requesting 192.168.141.50 and the WLC interface is on VLAN 141.

points to a network VLAN 141 issue.

E.

DHCP proxy is enabled. The WLC has received the client DHCP Discover, but there should be a DHCP

ACK because the client asked to use 192.168.141.50. This is a client supplicant DHCP issue.

 

Answer: B

 

 

QUESTION 263

You are tasked to convert autonomous AP static WEP users to Cisco Unified WLC 802.1X EAP users using their current Microsoft Active Directory accounts using a single WLAN. You need to preserve the wired VLAN that these users were connecting on. Which of the below procedures provides the best solution for this conversion?

 

A.

Configure the WLAN for Layer 2 security and use the WLC local RADIUS for authentication.

Configure the WLC local RADIUS server to authenticate each user against the Microsoft Active Directory.

Configure the WLC local RADIUS server to pass down IETF RADIUS attributes 64, 65, and 81 containing

the appropriate Layer 2 VLAN to the users.

B.

Configure the access point groups feature for two groups and map the WLAN to the correct interfaces for

each group.

Set the access points to the correct access point group for where these converted WEP users will be located.

Connecting users will be placed on the correct Layer 2 VLAN.

C.

Configure the WLAN for the appropriate Layer 2 security settings and ensure that AAA override is configured.

Configure an external RADIUS server to authenticate each user against the Microsoft Active Directory.

Configure the external RADIUS server to pass down IETF RADIUS attributes 64, 65, and 81 containing the

appropriate Layer 2 VLAN to the users.

D.

Configure two WLANs, one WEP, and one with EAP, but only broadcast the EAP WLAN so that only one

SSID is visible.

Configure each WLAN interface mapping to the correct and corresponding dynamic interface.

Then, use the WLC local RADIUS to authenticate users against the current Microsoft Active Directory.

Configure the WLC connecting trunk port to allow the appropriate user wired Layer 2 VLAN.

Configure the interface group feature to contain all of the dynamic interfaces needed.

Configure the single WLAN to use the interface group and authenticate to an external RADIUS server

configured to check the users against the Microsoft Active Directory.

The authenticated users will be placed on the correct VLANs dynamically.

 

Answer: C

C.

DHCP proxy is enabled. The WLC has sent the DHCP Discover out, but no DHCP Offer came back,

which points to an apparent WLC issue because the DHCP proxy should be disabled by default.

D.

DHCP proxy is enabled. The client is requesting 192.168.1.42 but the WLC interface is on a different

subnet, which points to an apparent client supplicant issue.

E.

DHCP proxy is disabled. The WLC has sent the DHCP Discover out, and a DHCP Offer came back of

192.168.142.31, but the client is not accepting it and therefore timing out.
