What is the major benefit of configuring the WLAN Security Switch (WSS) for PEAP as an authentication method?

• A.PEAP greatly reduces jamming attacks against the WLAN.
• B.It provides mutual authentication between the client and the authentication server.
• C.The shared key scheme, meaning the client and AP, must both have the same key.
• D.The client is required to authenticate using the WLAN firewall.

A customer is set up with a WLAN 2300 environment, and is using mobility domains. Using the CLI while logged into a Wireless Security System (WSS), which command allows the administrator to view mobility domain configuration information?

• A.show mobility-domain IP
• B.show mobility-domain attribute
• C.show mobility-domain
• D.show mobility-domain status

In a Smart Mobile Virtual Controller cluster, which WSS has a local copy of the domain configuration?

• A.The WSS configured as the primary seed in the cluster.
• B.The WSS configured as the Primary AP Manager and/or WSS acting as the Secondary
  AP Manager.
• C.Each WSS in the cluster.
• D.The WSS configured as the non-seed in the cluster.

You have implemented the WLAN Location Engine 2340 on a WLAN. This Engine is constantly reporting that WLAN devices are situated in one locale, however a physical inspection shows that these devices are actually located in another locale. Which circumstances can explain this problem? (Choose two.)

• A.The RF fingerprints need to be re-calibrated.
• B.The RF fingerprints are associated with the wrong locale.
• C.The MAC addresses on the WLAN devices are incorrect.
• D.The orientation of the AP 2332 access points need to be changed.

A 128-bit Wired Equivalent Privacy (WEP) is a shared key authentication system that means the client machine and Access Point share the same key. Which vulnerability is inherent with this type of security scheme?

• A.Any WEP enabled device transmitting OTA unencrypted makes the WLAN vulnerable.
• B.The open architecture of the WEP security scheme leaves it vulnerable to hackers.
• C.A static WEP key can be compromised if a hacker can gather enough transmitted packet information.
• D.The WEP security model is open to impersonation type hacking, by replication of MAC addresses, usernames, and passwords.
