H35-580_V2.0 Exam Dumps : HCIA-5G-RNP&RNO V2.0

According to the HCIA-5G V2.0 Exam Outline, handover execution failures can use the counters to collect failure reasons in SA networking, which corresponds to option A. The counters include N.HO.Exec.Fail.RadioResFail, N.HO.Exec.Fail.TAExceed, N.HO.Exec.Fail.NoRespFromUE, and N.HO.Exec.Fail.Other.

According to the NR-ARFCN (NR absolute radio frequency channel number), the NR-ARFCN value consists of two components: the band indicator and the channel number. The band indicator represents the frequency band on which the carrier frequency lies, while the channel number represents the specific carrier frequency within that band. The NR-ARFCN value is calculated by the following formula:

NR-ARFCN = FREF-Offs + NREF-Offs + ΔFGlobal * (Fcarrier - FREF-Offs) / AFGIobal

where FREF-Offs is the reference frequency offset, NREF-Offs is the reference NR-ARFCN offset, ΔFGlobal is the global frequency raster, Fcarrier is the carrier frequency, and AFGIobal is the absolute frequency granularity.

Given that AFGIobal is 15 kHz, FREF-Offs is 3000 MHz, and NREF-Offs is 600000, we can plug in these values and Fcarrier = 3300 MHz into the formula and get:

NR-ARFCN = 3000 + 600000 + 5 * (3300 - 3000) / 0.015 NR-ARFCN = 633000

Therefore, the correct answer is A.

According to the 5G-GUTI - 5G Globally Unique Temporary Identity, the NAS layer uses 5G-GUTI to replace IMSI as the temporary ID of a UE for security reasons. The 5G-GUTI is allocated by the AMF (Core Access and Mobility Management Function) at the time of network registration, and it is composed of the GUAMI (Globally Unique AMF ID) and the 5G-TMSI (5G Temporary Mobile Subscriber Identity).
