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

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

A customer complains about coverage reduction after modernization of 4G TDD 4x4 sites to Concurrent mMIMO B41/n41 with AEHC module 64T64R . Which of the following statements regarding RF design changes to increase the coverage is correct?

• A.  For concurrent mode, the tilt for both 4G and 5G is controlled by mMIMOSecSectorBFProfName and beamforming weight profile parameters.
• B.  5G tilt is controlled by tiltOffset , while the 4G tilt is controlled by mMIMOSecSectorBFProfName .
• C.  5G tilt is controlled by tiltOffset , while the 4G tilt uses the AEHC RET control port.
• D.  For concurrent mode, the tilt for both 4G and 5G is controlled by tiltOffset .

In a 5G NSA Option 3x deployment, why should we not define 5G neighbors in LTE sectors where there is no 5G coverage ?

• A.  All of the above.
• B.  Many redirections from 5G to 4G will be observed.
• C.  There will be LTE throughput degradation due to measurement gap configuration.
• D.  There will be unnecessary SCG neighbors, which can cause 4G-to-SCG handover performance to become worse.

In a high-mobility network, the maximum cell size must be restricted to 33 km . Which PRACH format and restricted-set type should be used?

• A.  Format 2 / Unrestricted Type
• B.  Format 0 / Type B
• C.  Format 1 / Type A
• D.  Format 1 / Type B

In NR SA Option 2, the UE is camped on an SA serving cell. An IRAT handover is triggered for a multi-QCI call, QCI 1 and QCI 6, due to weak coverage of the serving cell. What will happen to both QCIs during the IRAT handover toward LTE?

• A.  The QCI 1 bearer, or voice call, will be released, while the QCI 6 data bearer will continue on LTE.
• B.  The QCI 1 bearer, or voice call, and the QCI 6 data bearer will both continue on LTE.
• C.  IRAT handover is not supported in SA Option 2.
• D.  The QCI 1 bearer, or voice call, will continue on LTE, while the QCI 6 data bearer will be released.
