Free Ericsson ECP-383 Practice Exam with Questions & Answers

What is a cause of degradation in the RSRQ of a serving cell?

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.)

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?

You have collocated sectors In your 2G network on the GSM 900 and the DCS 1800 bands. Reviewing the network level traffic distribution, you noticed that the GSM 900 sectors have five times more traffic than the DCS 1800 sectors.

Which two actions would improve load balancing between these bands? (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.)

What are two advantages of using the Data Forwarding at Intra-LTE Handover feature? (Choose two.)

Which two benefits does OSS counter-based optimization provide compared to drive test measurements? (Choose two.)

What are two benefits of massive MIMO? (Choose two.)

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.)

Review the exhibit.

Using a radio performance monitoring tool, you fetch counters CI and C2 and calculate KPI K for the four 15-minute ROPs in an hour. The values obtained for the CI and C2 counters and for KPI K are shown In the exhibit.

In this scenario, what is the hourly value of KPI K?
