Nokia 5G RAN Network Operations Expert Sample Questions:
1. What is the purpose of license management functionality within NetAct as it relates to base station software and features?
A) It schedules routine site cleaning and maintenance visits
B) It tracks and manages license keys and entitlements that control which optional features and capacity levels are enabled on network elements, separate from the software installation itself
C) It tracks the physical inventory of spare RF cables stored at each site
D) It manages the PLMN IDs assigned to each base station
2. A NOC team is investigating a degradation in E-RAB / QoS flow setup success rate for a specific gNB.
Which approach is MOST effective for identifying the root cause?
A) Assuming the cause is always the subscribers' devices without checking network-side data
B) Restarting NetAct entirely without further analysis
C) Correlating the KPI degradation with active alarms, recent configuration changes, and relevant counters (e.g., resource congestion, transport, signaling) for that gNB during the affected period
D) Reviewing only high-level marketing performance summaries
3. What operational benefit does the Automatic Neighbor Relation (ANR) function provide to a NOC team managing 5G RAN configuration?
A) It automatically detects neighboring cells based on UE measurement reports and establishes or updates neighbor relations without requiring manual configuration of each relation
B) It automatically resolves all hardware faults on RF units without engineer intervention
C) It automatically changes the PLMN ID of a cell when roaming agreements change
D) It automatically increases a cell's transmit power whenever coverage gaps are detected
4. What is the key difference between a cell that has been administratively 'locked' (disabled) and a cell that reports 'Out of Service' due to a fault?
A) 'Locked' reflects a deliberate administrative action taken intentionally, while 'Out of Service' due to a fault reflects an unintended operational failure
B) 'Locked' cells always operate at higher transmit power than normal
C) There is no real difference; the two terms describe the same situation
D) 'Out of Service' cells are always the result of a software upgrade in progress
5. After a field engineer completes a baseband module replacement and confirms physical installation is complete, which set of remote checks should the NOC engineer perform to verify successful restoration of service?
A) Confirm the field engineer has left the site, without performing any further remote checks
B) Confirm that the cell's PCI has automatically changed to a new value
C) Confirm only that the module's indicator light is the correct color, without checking any system-level status
D) Confirm the cell(s) return to service without critical or major alarms, CPRI/eCPRI links to RF units are up, and relevant KPIs return to expected baseline levels
