Ericsson Certified Associate - Radio Network Optimization 認定 ECP-383 試験問題:

1. What is the recommended setting for the primaryCpichPower parameter according to Ericsson NDO guidelines?

A) 8-10% of min[maximumTransmissionPower, maxDlPowerCapability]
B) 36 dBm or more Independently of the maximum transmission power
C) less than 33 dBm
D) 33 dBm independently of maximum transmission power

2. An LTE operator explains that the traffic in cell A is very high compared to the traffic In cell B, which are close to each other. Cells A and B are using the same frequency.
In this scenario, which two actions would balance the traffic between cell A and cell B? (Choose two.)

A) Optimize the connected mode mobility parameters.
B) Optimize the idle mode related parameters.
C) Activate the inter-frequency load balancing feature.
D) Activate the TTI Bundling feature.

3. Performance Management Statistics have recently shown a sharp rise in received interference power on an LTE site during the busiest hours. A collocated WCDMA base station has recently acquired a new carrier and upgraded power amplifier. The upgrade correlates with the sharp rise in received interference power.
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) Review the site design in consultation with the Ericsson collocation and coexistence guidelines.
D) Reduce the hsPowerMargin parameter to make more power available for HSDPA.

4. 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.

5. After an optimization meeting, an operator decides to double the transmitted power of an LTE cell. To test the effect of this change, a static test is performed before and after the change.
Which statement is correct in this scenario?

A) The variation of the RSRP will depend on the bandwidth of the cell.
B) The RSRP received by the UE is increased by six dB.
C) The RSRP received by the UE is increased by three dB.
D) The RSRP received by the UE remains stable.
