5G can enable smart manufacturing and upgrade the manufacturing business model. Which of the
following are smart manufacturing scenarios empowered by 5G?
B
Explanation:
5G can enable smart manufacturing by providing ultra-reliable and low-latency communication,
enabling the deployment of various industrial internet of things (IIoT) applications, such as
collaborative control between machines. This allows for real-time coordination and control between
machines, enabling them to work together in a coordinated way to achieve a common goal, such as
increasing production efficiency or reducing downtime. This can help to improve the overall
performance of the manufacturing process and upgrade the manufacturing business model.

Which of the following 5G network technologies can reduce IoV latency?
A
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.

In SA networking, incorrect TAC configurations will cause UE access to fail.
A
Explanation:
In SA networking, incorrect TAC configurations will cause UE access to fail. This is because the UE
must be assigned a specific TAC value in order to be allowed to access the network. If the TAC value is
incorrect,
the
UE
will
not
be
able
to
access
the
network.

User performance testing can be used to collect Information regarding low Internet access rate for a
user. Which of the following information is not required to diagnose this issue?
D
Explanation:
SCTP tracing result is not required to diagnose a low Internet access rate for a user. User
performance testing can be used to collect information such as BLER (Block Error Rate) monitoring
result, downlink RSRP (Reference Signal Received Power) monitoring result, and MCS (Modulation
and Coding Scheme) count monitoring result. However, SCTP (Stream Control Transmission Protocol)
tracing result is not required to diagnose a low Internet access rate. Reference:

In NSA networking, X2 Interface self-setup between the 4G and 5G base stations falls. Which of the
following are possible causes?
D
Explanation:
The self-setup switch is not turned on. In NSA networking, X2 Interface self-setup between the 4G
and 5G base stations falls if the self-setup switch is not turned on. This is because the switch must be
enabled in order for the base stations to establish a connection. Other possible causes include the 5G
and 4G base stations belonging to different PLMNs (Public Land Mobile Networks), cell setup failing
on the LTE side, and the number of links established over the LTE X2 interface exceeding the board
specifications. Reference:

The segmentation method is the most important method for isolating faults on the transport
network. Different methods are used for different fault types.
A
Explanation:
The segmentation method is the most important method for isolating faults on the transport
network. Different methods are used for different fault types, such as Optical Time Domain
Reflectometry (OTDR) for fiber faults, Radio Frequency Interference Measurement (RFI) for radio
interference, and Signal-to-Noise Ratio (SNR) for signal noise. By segmenting the network, faults can
be
easily
identified
and
isolated.

Which of the following methods can be used to locate faults on the user-plane path?
C
Explanation:
According to the Huawei official documentation, "SCTP tracing can be used to check the SCTP
protocol-related information and locate faults on the user-plane path. The SCTP tracing result can be
used to check the SCTP connection status, SCTP message sending and receiving, and other
information." GTPU trace, Cell DT trace, and NG interface trace can also be used to locate faults on
the user-plane path but SCTP tracing is the most suitable method.
Which of the following are possible causes of NRDUCELL unavailability? (Choose All that Apply)
ABCD
Explanation:
According to Huawei official documentation, the following are possible causes of NRDUCELL
unavailability: A. RF fault B. BBP fault C. Insufficient CPRI bandwidth D. Clock exception. The RF, BBP,
and CPRI bandwidth are all important factors that contribute to the availability of the NRDUCELL. If
there is a problem with any of these components, it can cause the NRDUCELL to become unavailable.
Additionally, a clock exception, such as an issue with the timing or synchronization of the cell, can
also cause the NRDUCELL to become unavailable.
NRDUCELL unavailability can be caused by an RF fault, a BBP fault, insufficient CPRI bandwidth, or a
clock exception. According to
this page
, these are all possible causes of NRDUCELL unavailability.
If the subcarrier spacing (SCS) of a low-frequency cell Is 30 kHz and the bandwidth of each RB Is 360
kHz, theoretically, what value should the noise (dBm) over the air interface be?
B
Explanation:
The theoretically noise (dBm) over the air interface should be -116 dBm. The noise is calculated by
subtracting the noise figure of the receiver from the thermal noise floor, which is determined by the
subcarrier spacing and the bandwidth of each Resource Block (RB). In this case, the subcarrier
spacing is 30 kHz and the bandwidth of each RB is 360 kHz, so the thermal noise floor is -116 dBm.
Which of the following may cause exceptions In the GPS clock source?
ABCD
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.
The STR CROSFEEDTST command can be used to check for crossed feeder connections of an AAU.
A
Explanation:
According to Huawei's documentation, the STR CROSFEEDTST command can be used to check for
crossed feeder connections of an AAU. It is used to check whether the feeder cables of different
antennas are connected to the correct ports. The command can be executed on the AAU to detect
crossed feeder connections and ensure that the feeder cables are connected to the correct ports.
How many OM channels does a gNodeB support at most?
A
Explanation:
According to the Huawei official documentation, a gNodeB supports up to 4 OM channels at most.
These channels can be used to monitor and manage the gNodeB remotely. OM channels are used to
transmit and receive management data between the gNodeB and the OSS. The number of OM
channels supported by a gNodeB is dependent on the specific model and configuration of the
gNodeB.
The PING, TRACERT, CFMTRACE, CFMPING, and UDPECHO commands cannot be executed
simultaneously on the same board in a gNodeB.
A
Explanation:
The PING, TRACERT, CFMTRACE, CFMPING, and UDPECHO commands cannot be executed
simultaneously on the same board in a gNodeB. Executing multiple commands at the same time can
cause system instability, so it is not recommended to do so.
In NSA networking, which of the following objects are unnecessary to configrued for a gNodeB in SI
self-setup scenarios?
AD
Explanation:
In NSA networking, In self-setup scenarios, the USERPLANEHOST and SCTPHOST objects are
unnecessary to configure for a gNodeB. The USERPLANEHOST object is used to configure the IP
address of the user plane host, and the SCTPHOST object is used to configure the IP address of the
SCTP host. In self-setup scenarios, the gNodeB automatically obtains the IP addresses of the user
plane host and SCTP host from the S1-MME or S1-U peer. The USERPLANEPEER and SCTPPEER
objects are necessary to configure for a gNodeB in SI self-setup scenarios. They are used to configure
the IP address of the user plane peer and SCTP peer, respectively.
