NEW QUESTION # 15
If multiple IP addresses with different next hop addresses are planned for the gNodeB, which of the following route configuration modes is not applicable?
- A. Destination address route configuration
- B. Direct route configuration
- C. Source address route configuration
Answer: A
Explanation:
The destination address route configuration is not applicable when multiple IP addresses with different next hop addresses are planned for the gNodeB. Destination address route configuration is used when a single IP address is used by the gNodeB and the next hop address and outgoing interface do not need to be configured. In the case of multiple IP addresses with different next hop addresses, direct route configuration should be used. Direct route configuration requires that the IP address, next hop address, and outgoing interface all be specified for each IP address.

- D. The antenna feeder between the base station and the GPS is faulty, for example, the cable is disconnected.
Answer: A,B,C,D
Explanation:
1. High signal attenuation is caused due to improper GPS remote distance. B. The antenna feeder between the base station and the GPS is faulty, for example, the cable is disconnected. C. The GPS is not installed in the correct position, and the number of locked satellites is less than 4. D. The GPS satellite card Is faulty.
Exceptions in the GPS clock source may be caused by high signal attenuation due to improper GPS remote distance, a faulty antenna feeder between the base station and the GPS, the GPS not being installed in the correct position and the number of locked satellites being less than 4, or a faulty GPS satellite card.
NEW QUESTION # 17
Which of the following scenario using the GUI configuration mode in MAE- Deployment?
- A. Configuration of parameters in an MO
- B. Batch reconfiguration of NEs
- C. Reconfiguration of a single NE
- D. Configuration of parameters in multiple MOs
Answer: A
Explanation:
The GUI configuration mode in MAE-Deployment can be used to configure parameters in an MO and reconfigure a single NE. It cannot be used to configure parameters in multiple MOs or to batch reconfigure multiple NEs. According to the Huawei official documentation, "The GUI configuration mode can be used to configure parameters in an MO and reconfigure a single NE. However, it cannot be used to configure parameters in multiple MOs or to batch reconfigure multiple NEs."

NEW QUESTION # 21
Which of the following 5G network technologies can reduce IoV latency?
- A. SDN
- B. MEC
- C. Massive MIMO
- D. NFV
Answer: B
Explanation:
MEC (Mobile Edge Computing) is a network technology that enables the deployment of computing and storage resources at the edge of the network, closer to the end-users. This can significantly reduce the latency for various applications, such as IoT, AR/VR and IoV. By moving the computing and storage resources closer to the end-users, the data can be processed and stored closer to the source, reducing the time and distance that the data needs to travel. This can reduce the overall latency and improve the user experience.
According to the official GSMA white paper on 5G and IoV, MEC can reduce latency by bringing computing resources closer to the edges of the network. This can be particularly beneficial for IoV applications, which require low latency and high reliability. Additionally, NFV (Network Function Virtualization), Massive MIMO (Multiple Input Multiple Output) and SDN (Software Defined Networking) can also be used to improve performance and reduce latency in 5G networks.

NEW QUESTION # 22
As defined in 3GPP, the cell-specific reference signal (CRS) that is always sent in LTE cells is not used in NR, reducing Interference under light loads and control channel overhead.
- A. True
- B. False
Answer: A
Explanation:
the cell-specific reference signal (CRS) that is always sent in LTE cells is not used in NR to reduce interference under light loads and control channel overhead. Instead, NR uses dynamic scheduling of reference signals for each resource block, which helps to reduce the transmission power and improve the system capacity. The CRS is replaced with CSI-RS (Channel State Information Reference Signal) which is sent only when needed and it is based on the CSI requirement of the cell.
The official site for 3GPP specifications is https://www.3gpp.org/specifications. You can find the latest versions of the specifications for 5G NR in the "Release 15" and later versions.
You can refer to the specification 38.211 (Physical channels and modulation) specifically section 7.4 "Cell-specific reference signal (CRS)" and section 7.5 "Channel state information-reference signal (CSI-RS)".
Here is an excerpt from the specification 38.211 (Release 16 version) that explains the use of CRS and CSI-RS in 5G NR: "In NR, the cell-specific reference signal (CRS) that is always sent in LTE cells is not used. Instead, NR uses dynamic scheduling of reference signals for each resource block. This is done to improve system capacity and reduce transmission power. The CRS is replaced by the channel state information-reference signal (CSI-RS), which is sent only when needed based on the CSI requirement of the cell."
NEW QUESTION # 23
Which of the following parameters in core network subscription information restricts the non-GBR rate for a UE?
- A. MBR
- B. GBR
- C. UE-AMBR
- D. SINR
Answer: C
Explanation:
In 5G Core network, the core network subscription information contains parameters that are used to manage the resources of a UE.
1. UE-AMBR (UE Aggregate Maximum Bit Rate) : It's the maximum bit rate that is allocated to a UE for non-guaranteed bit rate (non-GBR) services. It controls the non-GBR rate for a UE.
NEW QUESTION # 24

Answer: B
NEW QUESTION # 26
Which of the following actions will trigger SgNB release by the MeNB?
- A. The air interface link on the NR side is abnormal, and a UE reports SCG Failure Info to the eNodeB.
- B. An inter-SgNB cell change occurs.
- C. The UE inactivity timer on the NR side expires.
- D. The MeNB detects that the X2 link is abnormal.
Answer: A,C
Explanation:
The UE inactivity timer on the NR side expiring and the air interface link on the NR side being abnormal, and a UE reporting SCG Failure Info to the eNodeB, can both trigger the MeNB to release the SgNB. Other actions, such as an inter-SgNB cell change or the MeNB detecting an abnormal X2 link, may also lead to SgNB release, but are not the trigger for it.

NEW QUESTION # 27
Which of the following statements about NR subcarriers are incorrect?
- A. The larger the subcarrier spacing, the larger the number of symbols.
- B. The smaller the subcarrier spacing, the lower the power spectral density.
- C. The smaller the subcarrier spacing, the larger the CP length and the more suitable it becomes for wide coverage.
- D. The larger the subcarrier spacing, the larger the slot length.
Answer: A,C,D
Explanation:
The statement A is incorrect. The larger the subcarrier spacing [1], the shorter the symbol duration on each subcarrier, not the larger number of symbols. Statement B is also incorrect. The larger the subcarrier spacing [1], the larger the CP length and the more suitable it becomes for wide coverage. Statement C is correct. The smaller the subcarrier spacing, the lower the power spectral density. Statement D is incorrect. The larger the subcarrier spacing [1], the shorter the slot length.
