Which purpose of using Metageek Chanalyzer during site survey is true?

• A. to verify the antenna pattern of the APs
• B. to show only the usage of the 2.4 GHz spectrum

Answer: D

Explanation: A spectrum analysis tool like Chanalyzer + Wi-Spy which shows you non-WiFi interference from devices like cordless phones, wireless video cameras, and microwave ovens. After you've detected an otherwise-invisible non-WiFi device, Chanalyzer + Wi-Spy can identify it and track it down.

NEW QUESTION 11
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 spectru
• B. With 802.11
• C. 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.
• D. 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.
• E. The clients could not transmit data at the highest mandatory rate of 54 Mbps due to limitations with 802.11b/
• F. This data-rate is only possible when transmitting at 802.11n speeds.
• G. 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.

NEW QUESTION 13
An access point will be partially exposed to the outdoor environment in a loading dock of a factory. How should this access point be deployed in a cost-effective manner?

• A. indoor AP with an external leaky coaxial cable
• B. outdoor mesh AP utilizing the 5-GHz band
• C. outdoor bridge AP pointing its antenna toward the factory
• D. indoor-based AP inside a NEMA-rated enclosure

Answer: B

Explanation: Because mesh radio waves have very high frequency in the 5-GHz band, the radio wavelength is small; therefore, the radio waves do not travel as far as radio waves on lower frequencies, given the same amount of power. This higher frequency range makes the mesh ideal for unlicensed use because the radio waves do not travel far unless a high-gain antenna is used to tightly focus the radio waves in a given direction.
