Nokia 5G RAN Network Operations Expert Sample Questions:

1. In the context of Nokia's Single RAN approach, what does it mean for a base station site's software package to support 'Single RAN'?

A) It means the site cannot receive any further software upgrades once Single RAN is enabled
B) It means the site requires a separate, dedicated physical cabinet for each radio access technology it supports
C) It means the site can only support a single radio access technology (e.g., only 5G) for its entire operational lifetime
D) It means a common hardware platform and software package can support multiple radio access technologies (such as 2G, 3G, 4G, and 5G) simultaneously on shared infrastructure

2. After a remote configuration change causes unexpected cell behavior, and the automatic fallback mechanism does not fully resolve the issue, what is the most appropriate next step for the NOC engineer?

A) Permanently decommission the affected cell
B) Restore the affected network element's configuration from the most recent verified pre-change backup
C) Apply a completely different, unrelated configuration template to the cell
D) Wait indefinitely without taking action, since the issue will eventually self-correct

3. During a Site Acceptance Test (SAT) for a newly commissioned 5G site, what is the NOC team's typical role?

A) To negotiate the commercial contract terms for the site's construction
B) To physically inspect the antenna mounting hardware for structural compliance
C) To install the physical RF cabling between the antenna and the baseband unit
D) To remotely verify that the site is visible and manageable from centralized OandM systems, that cells come into service correctly, that no unexpected alarms are present, and that initial performance indicators are within expected ranges

4. 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) Reviewing only high-level marketing performance summaries
B) Restarting NetAct entirely without further analysis
C) Assuming the cause is always the subscribers' devices without checking network-side data
D) 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

5. A field team is planning a site visit to investigate a persistent coverage issue and requests information from the NOC to help prepare. What information can the NOC engineer most usefully provide to support this site survey?

A) The current cell configuration, recent alarm history, and relevant performance data (such as RSRP
/SINR distributions and throughput trends) for the affected cell and its neighbors
B) The personal contact details of subscribers who have filed complaints about the area
C) A list of unrelated sites located in a different region of the country
D) The original purchase invoice for the site's equipment
