A user is participating in an IR.92 compliant VoLTE call.
What is the Quality of Service Class Indicator (QCI) of the bearer that carries SIP signaling?

• A.QCI 5
• B.QCI 1
• C.QCI 8
• D.QCI 2

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 three dB.
• C.The variation of the RSRP will depend on the bandwidth of the cell.
• D.The RSRP received by the UE is increased by six dB.

An operator receives customer complaints from an indoor location. The Issues result from a bad neighbor plan in a single RAT and frequency network.
Which two optimization processes would you use to resolve the problem? (Choose two.)

• A.prediction based neighbor optimization
• B.PM counter based neighbor optimization
• C.drive test based neighbor optimization
• D.call trace based neighbor optimization

You are performing a drive test on a cluster carrying commercial WCDMA traffic using a drive testing tool.
What are two metrics that would be detected using this tool? (Choose two.)

• A.speech accessibility
• B.RNC processor load
• C.channel element utilization
• D.packet throughput

You are performing a physical parameter optimization of an LTE network with an automatic tool that uses propagation predictions. As a result, the tool estimates an increase of RSRP from cell A at a particular location.
In this scenario, what has happened?

• A.Soft handover factor has increased.
• B.The antenna pattern of cell A has changed.
• C.The PRB utilization of cell A has decreased.
• D.Signal attenuation from the transmitter to the location has increased.
