NEW QUESTION 6
You must create a simple implementation of QoS on a WIAN. The implementation must allow clients to prioritize traffic into these four classes:
voice video best effort
background
Which option do you enable?

• A. NBAR2
• B. NetFlow v9
• C. WMM
• D. Cisco AVC

Answer: C

Explanation: WMM Classification
WMM uses the 802.1P classification scheme (part of the IEEE 802.1D MAC Bridges standard). This classification scheme has eight priorities that WMM maps to four access categories with WMM designations:
AC_BK--Background AC_BE--Best effort AC_VI--Video AC_VO--Voice

• C. antenna diversity
• D. temperature control
• E. PoE output

• A. 16 bytes
• B. 24 bytes
• C. 28 bytes
• D. 48 bytes
• E. 56 bytes
• F. 60 bytes
• G. 64 bytes

Answer: CF

NEW QUESTION 9
Which two modifications to station behaviors were designed in the IEEE 802.11e protocol? (Choose two.)

• D. continuous -72 dBm coverage from one access point

Answer: C

NEW QUESTION 11
A wireless phone user is having roaming difficulties and is experiencing gaps in the conversation while roaming.
WLC WLAN is configured as IEEE 802.1X and WPA2 and Aironet information element. What should be configured to fix the problem?

• A. IEEE 802.1X with Cisco Centralized Key Management
• B. IEEE 802.1X EAP-FAST
• C. DHCP required and DHCP proxy on WLC
• D. WPA1 and PSK

Answer: A

NEW QUESTION 12
An engineer is planning for a 24 Mbps data rate for a new installation. What is the coverage area from the AP if the environment and other factors are not taken into consideration?

• A. 225 feet
• B. 80 feet
• C. 150 feet
• D. 100 feet

Answer: A

Explanation: Coverage (Cell Size)
Lower data rates can be demodulated across greater distances than higher data rates. This is because of the lower complexity encoding schemes — the signal can be understood at a lower SNR. Enable lower data rates in order to increase the effective range of the AP; disable the lower data rates in order to decrease the effective range of the AP.

• A. Configure AVC profiles on the SSID
• B. Configure mobility groups between WLCs
• C. Use AVC to tag traffic voice traffic as best effort
• D. Use Cisco Centralized Key Management for authentication
• E. Configure AP groups between WLCs

Answer: BD

NEW QUESTION 14
What protocol can be enabled to listen in on IPv4 multicast streams and maintain a map of what each client requests on a wireless LAN controller?

NEW QUESTION 15
A customer is deploying a mesh outdoor wireless network based on FCC standards where spectrum analysis shows significant radar energy propagating throughout the coverage area from a local weather station. Which channel must be excluded from the access points RRM calculation to avoid network disruption due to weather radar activity?

• A. 132
• B. 44
• C. 11
• D. 36

Answer: A

Explanation: Weather radars operate within the 5600- to 5650-MHz band, which means that channels 124 and 128 might be affected, but also channels 120 and 132 might suffer from weather radar activity.
