The correct answer is B .
The Coverage and Quality use case is used in network planning and optimization to identify RF problem areas. These may include:
Low RSRP or weak coverage areas
Poor SINR or low radio quality areas
High interference zones
Overshooting cells
Coverage holes
Areas where users experience poor throughput or poor accessibility
This type of use case helps NPO engineers prioritize optimization actions such as antenna tilt changes, azimuth changes, parameter tuning, neighbor optimization, power adjustment, or site expansion.
The other options are not the primary purpose:
VPN tunnel configuration is a connectivity/security task.
LCBIN-to-CSV conversion is a data processing task.
Replacing the Kronos parser is a tool-chain or troubleshooting function, not the main purpose of coverage and quality analysis.
So the best answer is:
To identify problem areas such as low coverage or high interference.

The correct answer is D .
Admission control is responsible for deciding whether a new UE connection, bearer, service, or session can be accepted by the cell without negatively affecting existing users and services.
In 5G RAN, admission control checks available radio resources such as:
* PRB availability
* PDCCH/PUCCH capacity
* UE context capacity
* QoS requirements
* GBR or non-GBR bearer requirements
* Cell load and congestion status
It does not directly manage modulation schemes; that is handled by link adaptation. It also does not directly increase spectral efficiency or optimize downlink throughput, although good admission control indirectly protects user experience and avoids overload.
So the main role of admission control is:
To check whether there are enough resources for new connections.

The correct answer is B .
In 5G NSA EN-DC , the UE connects to LTE as the Master Cell Group , or anchor, and NR as the Secondary Cell Group . Not every LTE band can be paired with every NR band. The supported LTE-NR combinations are defined by 3GPP band-combination rules and must also be supported by the UE chipset and device capability.
For example, an operator may have LTE Band 3, Band 7, or Band 20 and NR n78, but only certain LTE-NR combinations may be valid for EN-DC. If the selected LTE anchor band is not supported in combination with the NR band, the UE will not be able to establish EN-DC even if LTE and NR coverage both exist.
Option C is not correct because dual-uplink support depends on UE capability and specific band-combination support; it cannot be guaranteed for all UE models. Option A and D are unrelated to the main purpose of checking 3GPP band combinations.
So the correct reason is:
To ensure that LTE and NR bands are compatible and allowed as EN-DC pairs.

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: A, B, C, and D .
This question is about Vo5G / VoNR IMS service support in 5G SA. For IMS-based services over 5G, different QoS flows are used for signaling, voice media, and video media.
Statement A is correct.
The feature supports IMS voice and video over 5G in the gNB for FR1 , including both TDD and FDD deployments.
Statement B is correct.
IMS signaling commonly uses 5QI 5 . This QoS flow carries SIP/IMS signaling messages such as registration, session setup, modification, and release.
Statement C is correct.
IMS conversational voice uses 5QI 1 , which is the standardized GBR QoS identifier for conversational voice.
Statement D is correct.
IMS conversational video commonly uses 5QI 2 , which is associated with conversational video traffic.
