Huawei HCIA-LTE-RNP&RNO (H35-560) Certification Sample Questions

01. Along a suburban street, a drive test shows the UE served by Cell K while Cell K's RSRP falls steadily. The UE sends repeated A3 measurement reports naming PCI 88, which the scanner shows as the strongest cell by about 10 dB. No handover command follows and the call drops; the UE then re-establishes on the cell with PCI 88.
Which action is most likely to fix this?
a) Raise the offset of the PCI 88 cell in Cell K's relation
b) Downtilt the cell with PCI 88 to reduce its footprint
c) Lower the hysteresis and time-to-trigger on Cell K
d) Add the PCI 88 cell to Cell K's neighbor relations

02. For a suburban LTE layer, the planner has these results:
- downlink MAPL at the planned edge rate: 151 dB
- uplink MAPL at the planned edge rate: 144 dB
- propagation model: path loss (dB) = 130 + 35 log10(d), with d in km
What cell radius should the plan use?
a) About 2.5 km
b) About 1.6 km
c) About 3.2 km
d) About 4.0 km

03. A batch of new SIM cards is issued for a logistics company's fleet. On the same cells, older SIMs attach normally, but every new SIM is rejected at the authentication step of the attach.
In which EPC node should the engineer first check that the new subscriptions were provisioned?
a) The MME
b) The PCRF
c) The HSS
d) The P-GW

04. An FDD UE receives downlink data on the PDSCH and has no PUSCH grant in the subframe where it must answer. A few subframes earlier it sent uplink data on the PUSCH, which the eNodeB has just decoded.
Which statements about the HARQ feedback for these two transmissions are correct?
(Choose two.)
a) The UE returns ACK/NACK for the PDSCH data on the PHICH
b) The UE returns ACK/NACK for the PDSCH data on the PUCCH
c) The eNodeB returns ACK/NACK for the PUSCH data on the PCFICH
d) The UE returns ACK/NACK for the PDSCH data on the PRACH
e) The eNodeB returns ACK/NACK for the PUSCH data on the PHICH

05. In this network, an intra-frequency neighbor meets the A3 entry condition when its RSRP exceeds the serving-cell RSRP plus the A3 offset plus the hysteresis; cell individual offsets are 0 dB. A UE on a suburban street measures its serving cell at -98 dBm. The A3 offset is 3 dB and the hysteresis is 1 dB.
Above which neighbor RSRP does the entry condition hold?
a) -102 dBm
b) -96 dBm
c) -95 dBm
d) -94 dBm

06. A scanner in a suburban drive test reports a cell with PCI 301. The engineer wants to know the cell identity group and the physical-layer identity within that group that make up this PCI.
Which pair corresponds to PCI 301?
a) Group 150, identity 1
b) Group 1, identity 100
c) Group 100, identity 1
d) Group 301, identity 0

07. An operator's LTE cells on carrier F1 hand UEs over to an overlaying F2 carrier only when F1 coverage becomes poor. To limit measurement overhead, F2 measurements should start only after the F1 serving cell has weakened.
Which event should start the gap-assisted F2 measurements?
a) Event A1, the serving cell becoming better than a threshold
b) Event A2, the serving cell becoming worse than a threshold
c) Event A3, a neighbor becoming offset better than the serving cell
d) Event A4, a neighbor becoming better than a threshold

08. A third sector is being added to an existing site on one carrier. The planning inputs are:
- the site's other two sectors: PCI 99 and PCI 100
- the facing sector of the nearest site, pointing at the new sector: PCI 97
- other first-tier neighbors: PCI 145 and PCI 202
Which PCI should the planner assign to the new sector?
a) PCI 101
b) PCI 102
c) PCI 103
d) PCI 145

09. Users in a shopping mall's food court complain of slow downloads at lunchtime. A test there at 12:30 shows RSRP of -75 dBm and SINR of 20 dB on the serving cell. The same test at 10:00, with the same RSRP and SINR, gives three times the throughput.
What does this indicate?
a) Weak coverage in the food court that worsens as crowds gather
b) Pilot pollution in the food court that appears at lunchtime
c) Excessive downtilt on the serving cell over the food court
d) Busy-hour load shared among many users on the serving cell

10. During SSV of a new 20 MHz site, whose cells a remote check confirmed are configured for 20 MHz as planned, downlink throughput tests are run on each cell in turn. On every cell the UE reports RSRP around -68 dBm, SINR around 26 dB and rank 2, and no other site is heard within 15 dB. Yet all three cells level off at about a fifth of the throughput that other 20 MHz sites reach under similar conditions.
What is the most likely cause?
a) Pilot pollution from surrounding sites near the mast
b) Weak coverage at the test positions of the cells
c) A site-level limit beyond the radio link, such as transport
d) A faulty feeder or connector on a single sector
