Ericsson Certified Associate - Radio Network Optimization Questions and Answers

Question 1

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:

A.

Optimize the connected mode mobility parameters.

B.

Optimize the idle mode related parameters.

C.

Activate the inter-frequency load balancing feature.

D.

Activate the TTI Bundling feature.

Question 2

Which two statements about physical resource blocks (PRB)s are correct? (Choose two.)

Options:

A.

The maximum number of assigned PRBs for a TTI can exceed the number of available PRBs in the cell for that TTI.

B.

The DL PRB distribution is not affected by the number of active cell users in the cell.

C.

A higher throughput is expected when more DL PRBs are assigned to a user for a TTI.

D.

The number of PRBs assigned for a user is dependent on the number of active users in the cell.

Question 3

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.)

Options:

A.

DRX

B.

256 QAM DL

C.

TTI Bundling

D.

SRVCC Handover to UTRAN

Question 4

Review the exhibit.

Cell A has neighbor relations with cells B and C which share the same frequency and PCI. Cells B and C do not share any overlapping area.

Referring to the exhibit which statement is correct?

Options:

A.

Handover performance of cell A is affected.

B.

There is no degraded performance expected in any of the cells.

C.

Handover performance of cell C is affected.

D.

Handover performance of cell B is affected.

Question 5

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?

Options:

A.

QCI 1

B.

QCI 2

C.

QCI 8

D.

QCI 5

Question 6

Which two channel bandwidths are available in LTE? (Choose two.)

Options:

A.

2.8 MHz

B.

1.4 MHz

C.

30 MHz

D.

15 MHz

Question 7

According to IR.92, which two LTE RAN functions are required to support VoLTE? (Choose two.)

Options:

A.

Service Specific Inactivity Timer

B.

RLC in Unacknowledged Mode for RTP transmissions

C.

Inter-frequency handover

D.

Multiple Radio Bearers per User

Question 8

Which statement describes uplink Discontinuous Transmission (DTX)?

Options:

A.

DTX is a method of saving battery power for the BTS by turning off the transmitter while "voice" is not present.

B.

DTX is a method of saving battery power for the MSC by turning off the transcoder while "voice" is not present.

C.

DTX is a method of saving battery power for the BSC by turning off the transcoder while "voice" is not present.

D.

DTX is a method of saving battery power for the MS by turning off the transmitter while "voice" is not present.

Question 9

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.)

Options:

A.

packet throughput

B.

RNC processor load

C.

channel element utilization

D.

speech accessibility
