SRAN-Radio-Network-Performance-Optimization MN: NCSS NPS - SRAN Radio Network Performance Optimization Certification Exam | GS40-NPS-SRPER-E-S03-2510 Questions and Answers

The correct answer is D: A, B, C, and D .

In 5G network slicing, S-NSSAI identifies a single network slice. It is composed of:

SST , or Slice/Service Type

SD , or Slice Differentiator

Statement A is correct.

The combination of SST + SD can uniquely identify a slice. For example, two slices may both use SST 1 for eMBB/MBB-type service, but different SD values can separate them for different enterprises, tenants, or service groups.

Statement B is correct.

SST is mandatory. It is an 8-bit numeric field that indicates the expected slice/service behavior, such as eMBB, URLLC, or mMTC.

Statement C is correct.

SD is optional. It is a 24-bit field used to differentiate multiple slices that may share the same SST.

Statement D is correct.

SST may use standardized values, such as SST 1 for eMBB, SST 2 for URLLC, and SST 3 for mMTC/MIoT. It may also use operator-specific or non-standardized values depending on deployment requirements.

The correct answer is C: From Stage 3 .

In LTE-to-NR mobility, the handover or redirection decision is normally based on a combination of:

LTE serving-cell signal level becoming weak enough, and

NR neighbor-cell signal level becoming strong enough.

From the diagram:

In Stage 1 , LTE is still good and NR is still weak, so LTE-to-NR HO should not be triggered.

In Stage 2 , the NR neighbor signal is improving, but the required combined LTE/NR mobility condition is not yet fully satisfied.

In Stage 3 , the NR neighbor signal has crossed the required NR threshold, while the LTE serving-cell signal has degraded enough to justify moving the UE from LTE to NR. This is the first valid stage where LTE-to-NR HO can be triggered.

In Stage 4 , NR is already clearly strong, but the handover could already have been triggered earlier in Stage 3.

The correct answer is C .

In a Concurrent mMIMO B41/n41 AEHC 64T64R deployment, LTE and NR share the same Massive MIMO active antenna system. Public Nokia material identifies AEHC as an AirScale Massive MIMO 64T64R B41 radio product, and Nokia’s AirScale Massive MIMO portfolio is designed for high-capacity 5G/RAN deployments.

Unlike a passive antenna system where coverage is changed mainly by physical/electrical RET, Massive MIMO coverage is strongly influenced by beamforming profiles and beamforming weight parameters . In concurrent LTE/NR operation, the RF design must consider the shared active antenna behavior, not independent passive RET-style tilt control per technology.

Therefore, for concurrent 4G/5G mMIMO coverage adjustment, the correct statement is:

The tilt/coverage behavior for both 4G and 5G is controlled by mMIMOSecSectorBFProfName and beamforming weight profile parameters.
