NEW QUESTION # 23
If a cell covers a high-speed railway on which UEs travel at 250 km/h, which PRACH format should be selected for that cell?
Answer: A
Explanation:
PRACH Format 3 is the intended selection because its 5 kHz subcarrier spacing provides greater tolerance to Doppler shift than the 1.25 kHz spacing associated with the other listed long-preamble formats.
The Physical Random Access Channel (PRACH) is used by the UE to initiate random-access procedures, including initial access and applicable mobility-related synchronization procedures.
In high-speed railway environments, rapidly moving UEs experience significant Doppler frequency shifts due to their motion relative to the serving base station.
Doppler shift is approximately proportional to carrier frequency and radial velocity.
At a UE speed of 250 km/h, the Doppler frequency can become sufficiently large to impair correlation and detection performance when narrow PRACH subcarrier spacing is used.
According to the standardized PRACH configurations, Formats 0, 1, and 2 use 1.25 kHz subcarrier spacing, while Format 3 uses 5 kHz.
The wider spacing reduces the relative frequency-offset sensitivity of the random-access preamble, helping improve detection reliability in high-mobility conditions.
PRACH planning must also account for maximum cell radius, propagation delay, cyclic prefix, and configured random-access occasions.
For the listed long-preamble formats and the stated high-speed scenario, Format 3 is therefore the preferred answer.
Official Reference: 3GPP TS 38.211, Section 6.3.3, Physical Random Access Channel ; TS 38.101-1, Section 6.3.3.4, Table 6.3.3.4-1, PRACH ON Power Measurement Period .
NEW QUESTION # 24
Which NAS security encryption algorithms are supported by an RG?
Select All that Apply
Answer: A,B,C
Explanation:
SNOW 3G, ZUC, and AES are standardized ciphering algorithms supported within the 5G security architecture for Non-Access Stratum (NAS) protection.
NAS security protects signaling exchanged between the UE and the Access and Mobility Management Function (AMF), including registration, authentication-related procedures, mobility management, and applicable NAS transport messages.
3GPP TS 33.501 identifies three principal 128-bit non-null ciphering algorithm families.
128-NEA1 is based on SNOW 3G, a stream-cipher algorithm originally developed for mobile-network security applications.
128-NEA2 uses the Advanced Encryption Standard (AES) in Counter (CTR) mode.
128-NEA3 is based on ZUC, a stream cipher standardized for mobile telecommunications security.
The serving network selects a ciphering algorithm according to the UE security capabilities and the algorithms permitted by the network configuration.
Option A is incorrect because quantum encryption is not one of the standardized NAS ciphering algorithms defined in the referenced 3GPP specification.
An additional standardized option, NEA0, represents null ciphering, but it is not listed among the available answers.
Therefore, B, C, and D identify the applicable standardized non-null algorithm families.
Official Reference: 3GPP TS 33.501, Sections 5.11.1.1 and 5.11.2, Ciphering Algorithm Identifier Values and Requirements for Algorithm Selection .
Technical warning / qualification: The question uses RG without defining the abbreviation. The explanation verifies standardized 5G NAS ciphering algorithms, but whether a particular residential gateway supports all three depends on its implementation and advertised security capabilities. The wording should specify the intended gateway type.
NEW QUESTION # 25
Which of the following 5GC modules connects to IMS?
Answer: A
Explanation:
The User Plane Function (UPF) is the 5G Core component that provides user-plane connectivity between PDU sessions and external Data Networks (DNs), including the IP Multimedia Subsystem (IMS).
IMS supplies multimedia communication services such as voice and video sessions using IP-based signaling and media transport.
In a 5G Standalone deployment, a UE can establish an IMS PDU session to access IMS services, including Voice over NR (VoNR).
The UPF processes user-plane packets associated with the PDU session and forwards traffic toward the appropriate external data network through the N6 interface.
For IMS services, this connectivity enables Session Initiation Protocol (SIP) signaling to reach relevant IMS components, such as the Proxy Call Session Control Function (P-CSCF).
The UPF also forwards media traffic according to the established packet-handling and forwarding rules.
The other functions serve different purposes.
AMF manages UE registration, access, and mobility procedures.
SMF controls PDU sessions, selects and configures UPFs, and manages applicable session-related QoS rules.
UDM manages subscription information and supports user-data services.
Although the SMF participates in establishing connectivity and policy enforcement, the UPF provides the actual user-plane path toward IMS.
Therefore, option A is correct.
Official Reference: 3GPP TS 23.501, Sections 4.2 and 6.2.3, 5G System Architecture and User Plane Function ; TS 23.228, Annex Y.9.2, IMS Services Architecture .
NEW QUESTION # 26
How many consecutive symbols does each SSB occupy in the time domain?
Answer: D
Explanation:
Each Synchronization Signal and Physical Broadcast Channel Block (SSB), formally identified as an SS
/PBCH block, occupies four consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols in the time domain.
In 5G NR, the SSB provides essential information for initial cell search, synchronization, physical cell identity detection, and acquisition of broadcast system information.
According to 3GPP TS 38.211, Section 7.4.3.1, an SS/PBCH block occupies four consecutive OFDM symbols, numbered 0 through 3.
The SSB contains the Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Physical Broadcast Channel (PBCH), and associated PBCH Demodulation Reference Signals (DM-RS).
The PSS enables the UE to detect a component of the physical cell identity and establish initial timing synchronization.
The SSS provides the remaining information required to determine the complete physical cell identity and assists synchronization.
The PBCH carries the Master Information Block (MIB), which provides essential configuration information for acquiring further system information.
In the frequency domain, each SSB spans 240 contiguous subcarriers.
Although multiple SSBs may be transmitted within an SSB burst set to support beam sweeping, the time- domain duration of an individual SSB remains exactly four consecutive OFDM symbols.
Official Reference: 3GPP TS 38.211, Section 7.4.3.1, Time-Frequency Structure of an SS/PBCH Block , Table 7.4.3.1-1.
NEW QUESTION # 27
In NSA networking, which of the following counters measure the number of abnormal SgNB releases caused by their respective causes?
Select All that Apply
Answer: A,B,C
Explanation:
Options B, C, and D are the intended answers because their counter names explicitly identify abnormal Secondary gNodeB (SgNB) release events and distinguish the associated failure causes.
In Non-Standalone (NSA) E-UTRA-NR Dual Connectivity, the SgNB provides NR secondary connectivity while the LTE eNodeB maintains the master connection.
Abnormal SgNB releases can occur because of radio-link failures, UE communication failures, transmission- network faults, or unsuccessful signaling procedures.
Option B - N.NsaDc.SgNB.AbnormRel.Radio.UeLost identifies abnormal release events associated with loss of UE communication at the radio layer.
This counter is relevant when investigating coverage deterioration, radio-link instability, or unexpected UE disappearance from the secondary connection.
Option C - N.NsaDc.SgNB.AbnormRel.NoReply identifies abnormal releases associated with missing expected responses during applicable procedures.
Option D - N.NsaDc.SgNB.AbnormRel.Trans identifies abnormal releases attributable to transmission- layer problems, such as faults affecting transport connectivity or associated signaling paths.
Option A - N.NsaDc.SgNB.Rel.Coverage identifies coverage-related SgNB releases, but its name does not classify those events as abnormal releases.
The key distinction is between general release counters and counters explicitly classified under abnormal- release causes.
Therefore, B, C, and D are the intended selections.
Official Reference: 3GPP TS 37.340, E-UTRA and NR Multi-Connectivity , Secondary Node Release procedures; TS 28.552, 5G Performance Measurements .
Technical warning / qualification: The precise N.NsaDc counter names are Huawei-specific. Their interpretations are consistent with the updated question bank, but the official Huawei performance-counter dictionary has not been supplied or independently verified. The 3GPP references establish the procedure, not these exact counter definitions.
