• Question 71:

  Refer to the exhibit.

  

  The signal is being degraded to the point of link drops. You have examined the roof and the visual sighting of the remote antenna. What could be causing the issue?

  A. The receiving antenna is too close to the transmitting antenna.
  B. The first Fresnel zone is more than 60% blocked by the parapet.
  C. The visual line of sight is more than 60% blocked by the parapet.
  D. The cable between the APs and the antennae is introducing too much loss.
  E. The roof material is absorbing too much of the signal.
  B. The first Fresnel zone is more than 60% blocked by the parapet.

• Question 72:

  When performing a post-installation audit with a auditing tool such as Ekahau, which two steps are associated with the active portion of the audit? (Choose two.)

  A. Check that all channels are supported by the APs regardless of client capabilities.
  B. Check for co-channel interference by standing near an access point on one channel and watching for other access points that are on the same channel.
  C. Verify that the network traffic of physical data rate and packet loss meets user requirements.
  D. Verify smooth roaming.
  E. Check to see if the signal level on other access points that are heard on the same channel is at least 19 dBm weaker than the access point that you are next to.
  C. Verify that the network traffic of physical data rate and packet loss meets user requirements.
  D. Verify smooth roaming.

• Question 77:

  Which two issues do access and backhaul radios experience in mesh networks? (Choose two.)

  A. The access radio has to connect to two or several points.
  B. The access cell usually covers more area at ground level that may have more sources of reflection and interference.
  C. The access cell radio range is larger than the backhaul radio range, which causes the backhaul cell radio to suffer from more interference.
  D. Backhaul radios are a bottleneck for throughput.
  E. RAPs help MAPs avoid coverage holes.
