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

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 2
• C.QCI 1
• D.QCI 8

Which two statements about the Radio Connection Supervision (RCS) algorithm in LTE are correct? (Choose two.)

• A.It supervises the radio connection between E-UTRAN and a UE in connected mode.
• B.It controls the modulation and coding scheme used in DL transmissions.
• C.It selects the number of PRBs assigned to users for downlink and uplink.
• D.It collects radio problems and inactivity information with the purpose to release resources.

Caller A is on a VoLTE call with Caller B.
Suddenly Caller A is no longer able to hear Caller B but Caller B can hear Caller A.
Which two call legs and directions should be analyzed first in this scenario? (Choose two.)

• A.the Caller A downlink
• B.the Caller B downlink
• C.the Caller A uplink
• D.the Caller B uplink

Using a cell optimization tool, you detect a sector that takes a large amount of traffic from a distant location that is covered by other sites and is also outside of the coverage predicted for this sector.
Which physical optimization action should you perform first In this situation?

• A.Downtilt the antenna and verify the result.
• B.Install TMA and verify the result.
• C.Increase the antenna height and verify the result.
• D.Increase the transmit power and verify the result.
