Ericsson Certified Associate - Radio Network Optimization Sample Questions:
1. Which two statements about the Radio Connection Supervision (RCS) algorithm in LTE are correct? (Choose two.)
A) It selects the number of PRBs assigned to users for downlink and uplink.
B) It collects radio problems and inactivity information with the purpose to release resources.
C) It controls the modulation and coding scheme used in DL transmissions.
D) It supervises the radio connection between E-UTRAN and a UE in connected mode.
2. What are two advantages of using the Data Forwarding at Intra-LTE Handover feature? (Choose two.)
A) User data can be forwarded directly between UEs over Wi-Fi.
B) TCP performance Is improved.
C) Data is received from two cells at the same time.
D) Packet loss is minimized during handovers.
3. Refer to the exhibit.
You identify an L700 cell serving a highway with poor handover success rate performance.
Referring to the exhibit, which two actions will help to improve the handover performance in this scenario?
(Choose two.)
A) Decrease the
timetotriggerA3 parameter.
B) Decrease the
A3offset
parameter.
C) Increase the
A3offset
parameter.
D) Increase the
timetotriggerA3 parameter.
4. A customer has Identified problems In an Indoor, medium loaded, urban area of a GSM/WCDMA collocated network. The problem seems to be in the uplink. The signal level received by the problematic site is high, and the downlink signal in the problematic area is acceptable.
Which two actions would you use to troubleshoot the issue? (Choose two.)
A) Decrease base station transmission power.
B) Investigate external interference.
C) Run a passive inter-modulation (PIM) analysis.
D) Add a pico cell In the same RAT and frequency.
5. Which two benefits does OSS counter-based optimization provide compared to drive test measurements?
(Choose two.)
A) OSS counters provide OPEX cost savings.
B) OSS counters only capture the outdoor performance.
C) OSS counters capture the indoor performance.
D) OSS counters allow throughput measurements in cells where no traffic is carried.
