Nokia MN: NCSS NPS - SRAN Radio Network Performance Optimization Certification Exam | GS40-NPS-SRPER-E-S03-2510 SRAN-Radio-Network-Performance-Optimization Prüfungsfragen mit Lösungen (Q13-Q18):

13. Frage
In the context of radio capacity management , what is the significance of Scheduling Request periodicity ?

A. It controls the downlink throughput.
B. It sets the maximum number of SSBs.
C. It affects the latency and number of connected users.
D. It determines the modulation scheme used.

Antwort: C

Begründung:
The correct answer is C .
Scheduling Request , or SR , is used by the UE to request uplink resources when it has uplink data to send.
The SR periodicity defines how often the UE gets an opportunity to send this scheduling request.
A shorter SR periodicity means the UE can request uplink resources more quickly, which improves uplink latency. However, it consumes more PUCCH/control-channel resources, reducing the number of UEs that can be efficiently supported.
A longer SR periodicity saves control-channel resources and can support more connected users, but it increases uplink access delay.
Therefore, SR periodicity is important because it creates a trade-off between:
Lower latency and higher connected-user capacity.

14. Frage
In the case of 5G SA, which of the following triggers the Radio Link Failure, or RLF, handling mechanism?

A. gNodeB and UE indication timer
B. gNodeB indication timer only
C. None of the above
D. UE indication timer only

Antwort: D

Begründung:
The correct answer is C.
In 5G SA, Radio Link Failure handling is mainly UE-driven. The UE monitors the radio link quality using lower-layer indications such as in-sync and out-of-sync indications. If the UE receives enough out-of-sync indications, it starts the relevant RLF timer, commonly associated with T310 behavior. If the link does not recover before the timer expires, the UE declares Radio Link Failure and starts recovery, such as RRC re- establishment.
The gNodeB can detect uplink problems and may release or reconfigure the UE, but the classical RLF handling mechanism is triggered at the UE side.
So the correct answer is:
UE indication timer only.

15. Frage
Which of the following statements about CBRA , or contention-based random access , is correct?

A. If there is already an existing connection, the gNB can instruct the UE to use a specific, dedicated preamble. Therefore, there is no risk of preamble collision, and contention resolution is not needed.
B. If the RACH preamble is not particularly robustly coded, there is a risk that random noise combines into something that the BTS receiver interprets as a valid preamble.
C. If there is no existing connection between the UE and the RAN, the UE autonomously selects a preamble from the provided range and starts the access procedure.
D. If the RACH procedure fails for an NSA UE, it reports the failure to the eNB via the 4G RRC connection, and the eNB informs the gNB via the X2 connection.

Antwort: C

Begründung:
The correct answer is B .
In contention-based random access , the UE chooses a random access preamble by itself from a configured pool of available contention-based preambles. This is typically used when the UE does not yet have a dedicated connection or when the network has not assigned a dedicated preamble.
Because multiple UEs may choose the same preamble at the same time, preamble collision is possible . That is why CBRA requires a contention resolution step.
Option C describes contention-free random access , not CBRA. In contention-free random access, the network assigns a dedicated preamble to the UE, so collision risk is avoided and contention resolution is not required.
Option A is not the correct CBRA principle being tested. RACH false detection can be a receiver/design issue, but it does not define the CBRA procedure.
Option D describes a possible NSA signaling behavior around access failure handling, but it is not the core correct definition of CBRA.
Therefore, the correct CBRA statement is:
The UE autonomously selects a preamble from the configured range and starts the random access procedure.

16. Frage
Which parameter defines the PRACH format ?

A. totalNumberOfRAPreambles
B. prachRootSequenceIndex
C. msg1-FrequencyStart
D. prachConfigurationIndex

Antwort: D

Begründung:
The correct answer is B .
The prachConfigurationIndex defines the PRACH configuration, including the PRACH time-domain occasions and the associated PRACH format according to the PRACH configuration tables. In 5G NR, PRACH configuration is based on 3GPP-defined PRACH tables, where the configuration index maps to the PRACH format and PRACH occasion structure.
The other options have different meanings:
A). msg1-FrequencyStart defines the frequency-domain starting position of PRACH occasion resources.
C). prachRootSequenceIndex defines the root sequence used for PRACH preamble generation.
D). totalNumberOfRAPreambles defines how many random access preambles are available.
Therefore, the parameter that defines the PRACH format is:
prachConfigurationIndex.

17. Frage
Identify the missing network components X, Y, and Z in the architecture diagram.

A. X: AMF, Y: IMS, Z: MME
B. X: AMF, Y: SGW, Z: MME
C. X: MME, Y: AMF, Z: IMS
D. X: MME, Y: IMS, Z: AMF

Antwort: A

Begründung:
The correct answer is B .
In the 5G Core , component X is connected to:
N2 from NG-RAN
N11 toward SMF
N15 toward PCF
N26 toward the EPC mobility entity
These are typical interfaces of the AMF , or Access and Mobility Management Function . Therefore, X = AMF .
In the EPC , component Z is connected to:
S1-MME from eNB
S11 toward the gateway
N26 toward the 5GC AMF
These are typical interfaces of the MME , or Mobility Management Entity . Therefore, Z = MME .
Component Y is outside the core user-plane path and represents the external service network connected through N6/SGi , commonly shown as IMS in voice-service architecture diagrams. Therefore, Y = IMS .
So the correct mapping is:
X: AMF, Y: IMS, Z: MME.
