Which two channel bandwidths are available in LTE? (Choose two.)
Which element is used in maintaining a 4G VoLTE call leg?
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.)
What are two benefits provided by the introduction of GPRS/EGPRS Downlink Power Control in a GSM network? (Choose two.)
Which two benefits does OSS counter-based optimization provide compared to drive test measurements? (Choose two.)

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 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.)
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?
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?
Which two use cases are specifically targeted for 5G technology? (Choose two.)
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.)
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.)
What is a benefit of soft handover?
You are using the Performance Measurements system for Ericsson WCDMA network analysis and must use predefined counters.
On which two levels would these counters be collected? (Choose two.)
According to IR.92, which two LTE RAN functions are required to support VoLTE? (Choose two.)
Which three service KPIs (S-KPIs) are obtained by DT measurement? (Choose three.)
A user is making a call on an LTE network.
In this scenario, which encoding schemes are used?
