問題 #17
When selecting an LTE anchor layer for EN-DC , why is it important to check 3GPP band combinations ?
答案：A
解題說明：
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.
問題 #18
Single Network Slice Selection Assistance Information , or S-NSSAI , identifies a network slice. Which of the following statements are correct regarding NSSAI ? Refer to the diagram for basic information.
答案：H
解題說明：
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.
問題 #19
In a 5G NSA Option 3x deployment, why should we not define 5G neighbors in LTE sectors where there is no 5G coverage ?
答案：D
解題說明：
The correct answer is A .
In 5G NSA Option 3x , LTE acts as the Master Cell Group , and NR acts as the Secondary Cell Group , usually added through EN-DC . If 5G NR neighbors are configured in an LTE sector where there is actually no 5G coverage , the LTE eNB may still configure the UE to perform NR measurements.
To perform NR inter-RAT or inter-frequency measurements, the UE may require measurement gaps .
During these gaps, the UE stops normal LTE reception/transmission activities to measure NR frequencies. If there is no real 5G coverage, those gaps become wasted measurement time and can reduce LTE user throughput.
Option B is not the best answer because if there is no 5G coverage, the main issue is not successful SCG addition or handover degradation, but unnecessary measurement activity. Option C is also not correct because redirection from 5G to 4G normally occurs when the UE is already on or connected to 5G coverage, which is not the case here.
Therefore, the main reason is:
LTE throughput degradation due to unnecessary measurement gap configuration.
問題 #20
The CB009425 feature provides several enhancements to improve the transmission link budget for VoNR, offering a better customer experience. Which statements are correct regarding this feature?
答案：D
解題說明：
The correct answer is D.
The feature is focused on improving VoNR link robustness and user experience, especially near the cell edge or in difficult RF conditions. VoNR is sensitive to packet loss, delay, and uplink coverage limitations.
Therefore, link-budget improvement features commonly target BLER behavior, transport block sizing, and MCS robustness.
Statement A is correct because minimizing Packet Loss Rate, or PLR, directly improves VoNR speech quality and reduces mute, clipping, or robotic voice effects.
Statement B is correct because VoNR bearers can use specific initial BLER targets. A more suitable BLER target helps the scheduler choose a more robust MCS for voice traffic.
Statement C is correct because a configurable uplink minimum TBS, or Transport Block Size, helps ensure that small VoNR packets are transmitted efficiently and reliably.
Statement D is correct because MCS downgrade control can improve robustness by selecting a more conservative modulation and coding scheme for VoNR DRBs when radio conditions require it.
Therefore, all listed enhancements are part of the VoNR link-budget improvement concept:
A, B, C, and D.
問題 #21
Which of the following best describes one of the primary purposes of the Coverage and Quality use case?
答案：C
解題說明：
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.
