Ericsson Certified Associate - Radio Network Optimization (ECP-383) Practice Test

Questions # 11:

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?

Options:

The RSRP received by the UE remains stable.

The variation of the RSRP will depend on the bandwidth of the cell.

The RSRP received by the UE is increased by six dB.

The RSRP received by the UE is increased by three dB.

Questions # 12:

What are two benefits provided by the introduction of GPRS/EGPRS Downlink Power Control in a GSM network? (Choose two.)

Options:

reduced power consumption in RBS

reduced downlink Interference levels In the system

reduced uplink interference levels in the system

increased PS accessibility

Questions # 13:

Several operators are using a Multi Operator Core Network (MOCN) with the Shared LTE RAN feature. Which element is shared by the operators in this scenario?

Options:

eNodeB

IMS

MME

SGW

Questions # 14:

What Is the purpose of the Location/Tracking Area update?

Options:

It is used to locate the UEs in idle mode.

It is used to internally locate UEs during on-going calls.

It is used to locate the originating UE.

It is used to locate the best IRAT cells.

Questions # 15:

Which statement is correct about network slicing?

Options:

Network slicking is a splitting of end users between competing operators in small population markets.

Network slicing is a customized division of a cellular network designed to allow end users to control allocation of network resources between themselves.

Network slicing is a separation of network architecture between vendors in a multivendor network.

Network slicing is a movement of network functions between aggregation layers to meet performance requirements for specific use cases.

Questions # 16:

Which identifier is used for locating a UE in a standalone LTE network?

Options:

RAC

TAC

LAC

URAC

Questions # 17:

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.)

Options:

Optimize the connected mode mobility parameters.

Optimize the idle mode related parameters.

Activate the inter-frequency load balancing feature.

Activate the TTI Bundling feature.

Questions # 18:

Which two statements are correct about a Self-Organizing Network (SON)? (Choose two.)

Options:

SON is a trace collection procedure for coverage prediction and reporting purposes.

SON is a centralized solution that automatically collects data and modifies parameters using a predefined algorithm.

SON is a drive test measurement tool for evaluation of network quality and new site location proposals.

SON is a combination of functions that automatically change network behavior.
