Question 1
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. Increase the power amplifier on the impacted collocated LTE sectors.
B. Reduce the hsPowerMargin parameter to make more power available for HSDPA.
C. 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 2
Which statement is correct about network slicing?
A. Network slicing is a movement of network functions between aggregation layers to meet performance requirements for specific use cases.
B. Network slicing is a separation of network architecture between vendors in a multivendor network.
C. Network slicing is a customized division of a cellular network designed to allow end users to control allocation of network resources between themselves.
D. Network slicking is a splitting of end users between competing operators in small population markets.
Question 3
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 RSRP received by the UE remains stable.
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 variation of the RSRP will depend on the bandwidth of the cell.
Question 4
Which two benefits does OSS counter-based optimization provide compared to drive test measurements?
(Choose two.)
A. OSS counters only capture the outdoor performance.
B. OSS counters allow throughput measurements in cells where no traffic is carried.
C. OSS counters capture the indoor performance.
D. OSS counters provide OPEX cost savings.
Question 5
After the installation of a new LTE antenna on a roof top, UL interference power for that sector is observed.
In this scenario, which two situations would cause the interference? (Choose two.)
A. Equipment that generates electrical magnetic fields are in the same location.
B. The antenna was placed on a mast near the edge of a rooftop.
C. A plastic enclosure was placed to cover the antenna.
D. Reflective objects such as metal chains or metal ladders were placed in front of the antenna.
