Free Nokia SRAN-Radio-Network-Performance-Optimization Exam Dumps Questions & Answers

Which of the following statements about CBRA , or contention-based random access , is correct?

• A.If there is no existing connection between the UE and the RAN, the UE autonomously selects a preamble from the provided range and starts the access procedure.
• B.If the RACH procedure fails for an NSA UE, it reports the failure to the eNB via the 4G RRC connection, and the eNB informs the gNB via the X2 connection.
• C.If the RACH preamble is not particularly robustly coded, there is a risk that random noise combines into something that the BTS receiver interprets as a valid preamble.
• D.If there is already an existing connection, the gNB can instruct the UE to use a specific, dedicated preamble. Therefore, there is no risk of preamble collision, and contention resolution is not needed.

Evaluate the impact of using MantaRay SON's centralized PCI optimization module compared to distributed SON implementations.

• A.Centralized PCI optimization can identify and resolve PCI issues across multi-vendor networks.
• B.Centralized PCI optimization offers less visibility into network configuration.
• C.Distributed SON implementations provide better optimization benefits.
• D.Distributed SON implementations are more effective in handling multi-vendor networks.

Which statement is not true about MantaRay SON ?

• A.It was previously known as EdenNet SON.
• B.It has an open framework for module development.
• C.Energy savings management is not covered.
• D.It supports multi-vendor and multi-technology RAN.

When selecting an LTE anchor layer for EN-DC , why is it important to check 3GPP band combinations ?

• A.To ensure that LTE and NR bands are compatible and allowed as EN-DC pairs
• B.To avoid configuring LTE with higher bandwidths
• C.To guarantee dual-uplink transmission support for all UE models
• D.To reduce the number of BTS neighbors required for 5G integration
