  C. Reduce the antenna height.
  D. Change the azimuth.
  D. Change the azimuth.

• Question 35:

  Performance Management Statistics have recently shown a sharp rise in received interference power on an LTE site during the busiest hours.

  What are two appropriate actions to solve this problem? (Choose two.)

  A. Request or perform a build audit of the newly upgraded collocated WCDMA site.
  B. Increase the power amplifier on the impacted collocated LTE sectors.
  C. Reduce the hsPowerMargin parameter to make more power available for HSDPA.
  D. Review the site design in consultation with the Ericsson collocation and coexistence guidelines.
  A. Request or perform a build audit of the newly upgraded collocated WCDMA site.
  D. Review the site design in consultation with the Ericsson collocation and coexistence guidelines.

• Question 36:

  How would you connect a Baseband module in the eNodeB to an Antenna Integrated Radio (AIR)?

  A. using optical fiber
  B. using a microwave link
  C. using an RJ-45 Ethernet cable
  D. using Bluetooth
  C. using an RJ-45 Ethernet cable

• Question 37:

  What is a purpose of Radio Resource Management (RRM) parameter optimization tools?

  A. coverage predictions
  B. azimuth adjustment
  C. geo-location procedures
  D. traffic balancing
  D. traffic balancing

• Question 38:

  Review the exhibit.

  

  An operator's LTE single layer network has a cell not carrying enough traffic. To increase the traffic carried by the cell, the operator decides to modify the Idle mode behavior of the cell. Values for the qRxLevMin and qQuaimin parameters are currently set to -120 dBm and -12 dB. Referring to the exhibit, which two configurations would be used to potentially increase the traffic carried by this cell? (Choose two.)

  A. Set the qRxLevMin parameter to -117 dBm.
  B. Set the qQualMin parameter to -15 dB.
  C. Set the qQuaiMin parameter to -9 dB.
  D. Set the qRxLevMin parameter to -123 dBm.
  B. Set the qQualMin parameter to -15 dB.
  D. Set the qRxLevMin parameter to -123 dBm.

• Question 39:

  A customer is deploying VoLTE and complains about high voice drop rates and voice quality degradation at the cell edge in most LTE cells in the area. The network has a dense WCDMA coverage on the 700 MHz band and patchy LTE coverage on the 2100 MHz band.

  Which two features would you activate to solve this problem? (Choose two.)

  A. DRX
  B. 256 QAM DL
  C. TTI Bundling
  D. SRVCC Handover to UTRAN
