Cisco 300-360 Online Questions & Answers

• Question 151:

  An engineer wants the controller to report when a client exceeds the minimum acceptable RSSI level, to ensure support for the minimum data rate required. Which controller option must be configured?

  A. Enable coverage hole detection
  B. Enable the coverage optimal mode.
  C. Set the DCA channel sensitivity to high.
  D. Set the coverage exception level per AP to 0.
  A. Enable coverage hole detection

  If clients on a lightweight access point are detected at threshold levels (RSSI, failed client count, percentage of failed packets, and number of failed packets) lower than those specified in the RRM configuration, the access point sends a "coverage hole" alert to the controller. The alert indicates the existence of an area where clients are continually experiencing poor signal coverage, without having a viable access point to which to roam. The controller discriminates between coverage holes that can and cannot be corrected. For coverage holes that can be corrected, the controller mitigates the coverage hole by increasing the transmit power level for that specific access point. https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-0/configuration/guide/c70/c70rrm.html

• Question 152:

  A wireless engineer is designing a wireless network to support real-time applications over wireless. Which IEEE protocol must the engineer enable on the WLC so that the number of packets that are exchanged between an access point and client are reduced and fast roaming occurs?

  A. 802.11w
  B. 802.11r
  C. 802.11k
  D. 802.11i
  B. 802.11r

• Question 153:

  A customer wants to implement a wireless network in a historic location, but is concerned about the structural and aesthetic impact to the facility. Which benefit of using wireless mesh addresses these concerns?

  A. PoE is required only at the installation location.
  B. The APs do not have LED lights.
  C. More wireless channels can be supported.
  D. APs do not need network connections.
  D. APs do not need network connections.

• Question 154:

  Which option is an advantage at using Cisco CleanAir technology in your wireless network?

  A. CleanAir can be used on an AP in monitor mode so that the AP serves client traffic and monitors for interference simultaneously.
  B. A single CleanAir AP can be used to analyze RF traffic from many APs
  C. CleanAir is a software feature that can be added to arty AP to start monitoring interference and air quality.
  D. CleanAir operates 24/7 and constantly monitors for interference and air quality issues.
  D. CleanAir operates 24/7 and constantly monitors for interference and air quality issues.

  An advantage of CleanAir technology is that it operates 24/7, constantly monitoring for interference and air quality issues (see Figure 2). This allows IT to take a more proactive approach to spectrum management. Instead of waiting for interference to be reported by an end user (in the form of a trouble ticket) and then dispatching a tool to analyze the problem, IT can find interference as soon as it occurs and take immediate action. Having a 24/7 history also makes it possible to look back in time. Using historical data, it's easy to perform analyses of trends over time. https://www.cisco.com/c/en/us/solutions/collateral/enterprise-networks/cleanairtechnology/white_paper_c11-599260.html

• Question 155:

  An engineer is performing a predictive wireless design for a carpeted office space, which requires voice capability and location services. Which two requirements are inputs to the design? (Choose two.)

  A. overlapping -67 dBm coverage from three access points
  B. overlapping -75 dBm coverage from three access points
  C. overlapping-72 dBm coverage from two access points
  D. continuous -67 dBm coverage from one access point
  E. continuous -72 dBm coverage from one access point
  A. overlapping -67 dBm coverage from three access points
  D. continuous -67 dBm coverage from one access point

  For a voice network the APs are grouped closer together and have more overlap than a data-only installation because voice clients need to roam to a better AP before dropping packets. Generally, you should create smaller cells than for data-only networks and ensure the overlapping cell edges are at or above -67 dBm.

  B. show ip igmp groups
  C. show ip pim neighbor
  D. show ip device tracking all
