Cisco 642-742 Exam Syllabus Topics:

Cisco Implementing Cisco Unified Wireless Voice Networks (IUWVN) v2.0 Sample Questions:

1. How would an engineer ensure that a wireless client can conduct traffic admission?

A) verify traffic is admitted by round robin
B) verify traffic is admitted as it passes down the OSI layers
C) verify interface group is configured for traffic admission
D) verify client supports WME for traffic admission

2. Refer to the exhibit.

An engineer notices VoWLAN calls getting dropped and uses Spectrum Expert to analyze the RF utilization. Based on the Spectrum Expert capture, what two options describe the interferer and how to mitigate it? (Choose two.)

A) DECT 6.0 Cordless phone interference
B) Disable RRM
C) Disable UNII-2 channels
D) Radar interference
E) Disable DFS
F) Bluetooth interference
G) Disable DCA
H) microwave oven interference

3. An engineer notices that the batteries on a Cisco 792X series wireless phone are draining quite a bit even while not placing calls. What should be changed on the SSID to fix this?

A) set P2P to forward down-stream so that clients are not interfering with each other
B) set DTIM to 2 on the operational band of the voice clients
C) enable Multicast Direct to cut down on the multicast processing
D) enable U-APSD on the WLAN to save power

4. A customer is having issues streaming video over wireless in a few high-density areas of their campus. After further investigation, the administrator has singled out the issue pertains to the clients associated to 802.11b/g only access points. The rest of the campus is covered in 802.11n access points. What is a possible reason for the issue with video streaming on the 802.11b/g access points as opposed to the 802.11n access points?

A) Due to the High-Density environment, there was high-utilization of the wireless spectrum. With 802.11n. the access points are able to aggregate the MSDU and MPDU frames into A-MSDU and A-MPDU frames, utilizing less airtime to transfer data.
B) The wireless clients were all transmitting at 802.11b data rates and would have operated properly had they been transmitting and receiving at 802.11g rates.
C) The wireless controller was denying the client access to the video due to multicast-direct supporting the PHY rate of 48000 that the 802.11b/g client could not handle.
D) The clients could not transmit data at the highest mandatory rate of 54 Mbps due to limitations with 802.11b/g. This data-rate is only possible when transmitting at 802.11n speeds.

5. Which two critical requirements must be addressed in the RF site survey for wireless video
surveillance? (Choose two.)

A) jitter
B) channel selection
C) WLC configuration
D) bandwidth
E) packet loss
