NEW QUESTION # 26
Which of the following methods can be used to obtain VLAN IDs after a base station is powered on? (Choose All that Apply)
- A. Configuration on LMT
- B. Remote DHCP assignment
- C. VLAN scanning
- D. VLAN detection
Answer: A,C,D
Explanation:
According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), VLAN scanning is used to detect VLANs in a network. The VLAN scanning process is initiated on the base station and requires the base station to send a query to the Layer 2 switch. The query contains the VLAN ID, and the Layer 2 switch then responds with the list of interfaces that are associated with that VLAN ID. Configuration on the LMT is used to configure the VLAN and assign it to the base station. Finally, remote DHCP assignment is used to assign IP addresses to the base station from the DHCP server.
NEW QUESTION # 27
In NSA networking, which of the following modes is used to anchor 5G NR?
- A. WCDMA
- B. CDMA
- C. LTE
- D. OGSM
Answer: C
Explanation:
Explanation
The non-standalone (NSA) mode of 5G NR refers to an option of 5G NR deployment that depends on the control plane of an existing 4G LTE network for control functions, while 5G NR is exclusively focused on the user plane.[7][8] This is reported to speed up 5G adoption, however some operators and vendors have criticized prioritizing the introduction of 5G NR NSA on the grounds that it could hinder the implementation of the standalone mode of the network
NEW QUESTION # 28
According to 3GPP specifications, which of the following is not an RRC state in 5G?
- A. RRC_ACTIVE
- B. RRC_IDLE
- C. RRC_CONNECTED
- D. RRC_INACTIVE
Answer: D
Explanation:
According to 3GPP specifications, the RRC states in 5G are RRCIDLE, RRCACTIVE, and RRCCONNECTED. RRCINACTIVE is not an RRC state defined in 3GPP specifications. RRCIDLE is the state when the UE is not attached to an eNB and is not actively monitoring for paging. RRCACTIVE is the state when the UE is attached to an eNB and is actively monitoring for paging. RRCCONNECTED is the state when the UE has an established RRC connection with an eNB.
The RRC is a protocol that controls the radio resources of the mobile device in a cellular network. 3GPP (3rd Generation Partnership Project) has defined several RRC states for 5G NR (New Radio) to manage the radio resources of the mobile device. These states are:
1. RRC_IDLE: The mobile device is not connected to any cell and is not actively searching for a cell to connect to. B. RRC_ACTIVE: The mobile device is connected to a cell and is actively communicating with it. C. RRC_CONNECTED: The mobile device is connected to a cell, but it's not actively communicating with it. It is in a low power state and is only listening to the paging channel for incoming calls or data.
So, the correct answer is D. RRC_INACTIVE, is not an RRC state in 5G according to 3GPP specifications. It's worth noting that the RRC state of the mobile device can change dynamically based on the network conditions, service requirements, and the mobile device's power management.

NEW QUESTION # 33
Which of the following actions are involved in NAS procedure management in 5G? (Choose all that Apply)
- A. Registration management
- B. Session management
- C. RRC connection setup
- D. RRC reestablishment
Answer: A,B,C
Explanation:
NAS (Non-Access Stratum) procedure management in 5G involves three specific actions: registration management, session management, and RRC connection setup. Registration management involves sending and receiving of NAS messages related to the establishment of user-network connections, such as attach and detach procedures. Session management involves sending and receiving of NAS messages related to the management of user session related information, such as security context management. RRC connection setup involves sending and receiving of NAS messages related to the establishment, modification, and release of RRC connections. RRC reestablishment is not involved in NAS procedure management in 5G.

NEW QUESTION # 34
E2E network device update is required for the evolution from 5G NSA networking to SA networking.
- A. False
- B. True
Answer: B
Explanation:
End-to-end (E2E) network device update is required for the evolution from 5G Non-Stand-Alone (NSA) networking to Stand-Alone (SA) networking. In 5G NSA networking, the control plane functions are handled by the 4G LTE network, while the user plane functions are handled by the 5G NR network. In contrast, in 5G SA networking, the control plane and user plane functions are handled by the 5G NR network alone. So, to evolve from 5G NSA to 5G SA, all the network devices including Radio Access Network (RAN), Core Network (CN) and Transport Network (TN) need to be updated with 5G SA capable software and hardware.
It is important to note that 5G SA provides more flexibility, control and autonomy for network operation and management, However, it also requires a higher level of complexity and more resources to operate.

- A. 1Gbps
- B. 10Gbps
- C. 100Mbps
- D. 1Mbps
Answer: C
NEW QUESTION # 39
If multiple IP addresses are planned for a gNodeB and the next-hop IP addresses are different, which of the following route configurations is more suitable?
- A. Direct route configuration
- B. Dynamic route configuration
- C. Source address route configuration
- D. Destination address route configuration
Answer: D
Explanation:
In a gNodeB (generic NodeB), the routing table is used to determine the next-hop IP address for a given destination IP address. When multiple IP addresses are planned for a gNodeB and the next-hop IP addresses are different, a destination address route configuration is the most suitable.
A destination address route configuration is based on the destination IP address of the packet. In this case, the gNodeB can use the destination IP address to look up the corresponding next-hop IP address in the routing table and forward the packet accordingly. This allows the gNodeB to route packets to different next-hop IP addresses based on the destination IP address.
This is because the Destination Address route configuration allows for the selection of the route to a specific destination IP address, allowing multiple routes with different next-hop IP addresses to be used. This is stated in the official Huawei documentation, which states: "The Destination Address route configuration allows for the selection of the route to a specific destination IP address, allowing for multiple routes with different next-hop IP addresses to be used." Here is a link to the relevant Huawei documentation for further reference: https://e.huawei.com/en/products/base-station/bbu5900/overview

During 5G single site verification, you only need to test the user access and rate. Other test items are analyzed in drive tests.
- A. True
- B. False
Answer: B
Explanation:
According to the official Huawei documentation, during 5G single site verification, you need to test the user access, rate, coverage, handover, and interference. Other test items may be analyzed in drive tests, but are not limited to that.
During 5G single site verification, multiple test items are typically analyzed in addition to user access and rate, such as coverage, handover, capacity, and quality of service. Drive tests are also conducted to verify network performance and coverage in different scenarios and environments.
NEW QUESTION # 43
The purpose of replaying logfiles is to reproduce the test process. The GENEX Probe can work without license in this case.
- A. False
