Q72. - (Topic 6)
Which option best describes the limitation of a client that is attempting to manage a WLC while using the client wireless adapter connection to the wireless infrastructure?
A. Controllers must be managed using only secure protocols (that is, SSH and HTTPS), not nonsecure protocols (that is, HTTP and Telnet).
B. Read-write access is not available; only read-only access is supported.
C. Uploads and downloads from the controller are not allowed.
D. Wireless clients can manage other controllers, but not the same controller and the AP to which the client is associated.
Answer: C
Explanation:
The Cisco WLAN Solution Management over Wireless feature allows Cisco WLAN Solution operators to monitor and configure local WLCs using a wireless client. This feature is supported for all management tasks, except uploads to and downloads from (transfers to and from) the WLC.

Q73. - (Topic 4)
Which two types of encryption does Windows support for WPA2 security for wireless connections? (Choose two.)
A. AES
B. DES
C. PGP
D. TKIP
E. WEP
Answer: A,D
Explanation:
TKIP and AES are two different types of encryption that can be used by a Wi-Fi network. TKIP stands for “Temporal Key Integrity Protocol.” It was a stopgap encryption protocol introduced with WPA to replace the very-insecure WEP encryption at the time. TKIP is actually quite similar to WEP encryption. TKIP is no longer considered secure, and is now deprecated. In other words, you shouldn’t be using it. AES stands for “Advanced Encryption Standard.” This was a more secure encryption protocol introduced with WPA2, which replaced the interim WPA standard. AES isn’t some creaky standard developed specifically for Wi-Fi networks; it’s a serious worldwide encryption standard that’s even been adopted by the US government. For example, when you encrypt a hard drive with TrueCrypt, it can use AES encryption for that. AES is generally considered quite secure, and the main weaknesses would be brute-force attacks (prevented by using a strong passphrase) and security weaknesses in other aspects of WPA2.

VPN Module
Diagnostic Reporting Tool (DART, to analyze and troubleshoot connections)
Network Access Module (provided as part of the Network Access Manager to manage user and device identity over wired and wireless deployments)
Posture Module (to identify the operating system, antivirus, anti-spyware, and firewall installed on the host)
Telemetry (used with the Cisco IronPort Web Security Appliance to identify the source of malwares)
Web Security Module (cloud-based real-time web protection and policy enforcement) You can just install the modules you need, then add or remove modules as the security needs change.

Which two actions are best for deploying VoWLAN on a wireless network? (Choose two.)
A. Minimize the use of Class 3 Bluetooth devices.
B. Minimize the use of analog cameras.
C. Minimize the use of IP cameras.
D. Maximize client access by enabling all data rates used by clients.
E. Maximize client access by enabling only a few high data rates used by clients.
Answer: B,E
Explanation:
Analog cameras can operate in the same frequency of the wireless network, causing interference.
The goal in setting the data rates for the VoWLAN network is to match the data rates of VoWLAN handsets as closely as possible, enabling a few high data rates used by the clients.
