Cisco 300-360 Online Questions & Answers

• Question 11:

  When designing a large, high-availability wireless network, what changes to a mobility- group would create less load on the controllers while maintaining the same mobility messages?

  A. remove unnecessary controllers from the mobility-group to cut down on the controller's messaging load
  B. separate the controllers into different mobility-groups per controller to only send relevant messaging to controllers in different groups
  C. configure mobility-group multicast messaging
  D. configure the controllers into separate RF-Groups from the mobility-groups to cut down on controller processing load
  C. configure mobility-group multicast messaging

• Question 12:

  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
  B. outdoor mesh AP utilizing the 5-GHz band

  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.

• Question 13:

  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 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.
  D. 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.
  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. Configure WLAN gold QoS.
  C. Configure WLAN Aironet information elements to enabled.
  D. Configure WLAN setting to enable WMM.
  E. Configure global 802.11b/g/n or 802.11a/n/ac, or both, to voice CAC.
  F. Configure DTIM = 2.
  A. Configure WLAN platinum QoS.
  D. Configure WLAN setting to enable WMM.
  E. Configure global 802.11b/g/n or 802.11a/n/ac, or both, to voice CAC.

• Question 15:

  Cisco 7925G phones are experiencing intermittent connectivity issues. The wireless survey reveals that the facility has no current coverage holes. The radios on the 2.4GHz channel have all been statically set to power level 1. Which two reasons could explain why the phones are having issues on this wireless network? (Choose two.)

  A. The phones are experiencing excessive co-channel interference.
  B. The phones only operate on the 2.4 GHz band when the power level is above 25 mW.
  C. The phones are not transmitting at the same power levels as the access points.
  D. The phones are experiencing delays of less than 30 ms within their coverage cell.
  E. The phones are receiving greater than -67 dBm RSSI on the 2.4 GHz band.
  A. The phones are experiencing excessive co-channel interference.
  C. The phones are not transmitting at the same power levels as the access points.

• Question 16:

  F. kitchen

• Question 17:

  Which two options describe best practices that must be completed after a wireless installation is finished? (Choose two.)

  A. Make sure that there are no spaces between the devices on the rack that the Wireless Lan Controller is installed.
  B. Consult with the customer to ensure that the IT staff has a complete set of design and installation documents.
  C. Make sure the customer is aware that they should consider purchasing a support contract immediately after the installation is complete.
  D. Spend time with the customer to show them the controller GUI and inform them how they can reach the Cisco TAC if they have any problems.
  E. Test all the customer's wireless devices and applications to ensure they are working properly.
  B. Consult with the customer to ensure that the IT staff has a complete set of design and installation documents.
  E. Test all the customer's wireless devices and applications to ensure they are working properly.
