Nokia 5G RAN Network Operations Expert Sample Questions (Q80-Q85):

NEW QUESTION # 80
Before performing a remote software upgrade on a base station, what should a NOC engineer ensure has been completed regarding the site's current state?

Answer: B

Explanation:
Taking and verifying a current configuration and software backup before a remote software upgrade is a fundamental pre-upgrade step. This backup captures the site's known-working state - including its current software load and configuration parameters - immediately before changes are introduced. If the upgrade fails, results in unexpected behavior, or the automatic fallback mechanism does not fully restore normal operation, this backup provides a verified restore point that the NOC can use to recover the site to its prior working condition, minimizing downtime and avoiding the need for a more disruptive recovery process such as a full re-commissioning. Deleting alarm history, changing the PLMN ID, or removing neighbor relations are not standard or appropriate pre-upgrade steps; they would either destroy useful troubleshooting history, disrupt subscriber service through incorrect network identification, or unnecessarily degrade mobility performance, none of which relate to safely preparing for a software upgrade.


NEW QUESTION # 81
During a Site Acceptance Test (SAT) for a newly commissioned 5G site, what is the NOC team's typical role?

Answer: C

Explanation:
During a Site Acceptance Test for a newly commissioned site, the NOC team's role centers on remote verification from the centralized operations perspective, complementing the field team's physical inspection and commissioning activities. This typically includes confirming that the new site and its cells are visible, reachable, and manageable through centralized tools such as NetAct (confirming O and M connectivity is correctly established), verifying that all expected cells come into service without configuration errors, checking that no unexpected or unresolved alarms are present that would indicate an incomplete or faulty installation, and reviewing initial performance indicators (such as successful connection attempts and basic KPI reporting) to confirm the site is functioning as intended before it is accepted into normal operation.
Physical inspections of mounting hardware, cabling installation, and commercial/contractual matters fall outside the NOC's remote operational role and are handled by field engineering, construction, and commercial teams respectively.


NEW QUESTION # 82
Why is it important for the NOC engineer to confirm the affected cell is locked and showing as out-of-service (in a planned state) before instructing the field engineer to disconnect any RF cabling at the antenna?

Answer: C

Explanation:
Confirming that a cell is locked and in a planned out-of-service state before any physical RF disconnection serves two important purposes. From a safety perspective, a locked cell is not actively transmitting in normal traffic-carrying operation, reducing RF exposure risk to the field engineer working near the antenna or cabling. From an operational perspective, performing the disconnection on a cell already in a planned, controlled state ensures that the resulting loss of RF connectivity is correctly interpreted within the context of an ongoing planned maintenance activity, rather than triggering an unplanned fault condition that might generate urgent alarms, automatic notifications, or even unnecessary escalations to other teams who are unaware that work is in progress. Locking a cell does not increase its transmit power (the opposite is true - it stops normal transmission), does not trigger any automated parts dispatch, and has no effect on PLMN ID or network-wide UE registration, which are unrelated to a single cell's administrative state.


NEW QUESTION # 83
Why do NOC teams typically schedule software activation activities - which require a base station restart - for late-night or off-peak hours rather than during the day?

Answer: B

Explanation:
Activating new software on a base station typically requires the affected unit (or units) to restart, which causes a brief interruption to service for any UEs connected through that cell during the restart. To minimize the impact of this unavoidable interruption, NOC teams schedule such activities during maintenance windows that coincide with periods of lowest network traffic - commonly late at night or in the early morning hours - when the fewest subscribers are likely to be actively using the network. This reduces the number of dropped sessions and the overall visibility of the brief outage to end users. There is no technical restriction preventing restarts during daylight hours, nor does activation duration meaningfully change based on time of day, and NetAct does not impose a blanket restriction on when configuration changes can be submitted - the scheduling decision is an operational best practice driven by minimizing customer impact, not a technical limitation.


NEW QUESTION # 84
What is the function of cell reselection priority parameters configured for idle-mode UEs across different frequency layers (e.g., 5G vs. 4G, or different 5G bands)?

Answer: A

Explanation:
Cell reselection priority parameters are broadcast to idle-mode UEs and inform them how to prioritize different frequency layers (such as a 5G band versus an LTE band, or multiple 5G bands) when more than one suitable cell is available for camping. By assigning higher reselection priority to certain layers, an operator can influence idle-mode UE distribution - for example, encouraging UEs to camp on a 5G layer where available to ensure faster initial access to 5G services, or directing UEs away from a layer that is being prepared for maintenance. These parameters work alongside reselection thresholds and timers that prevent excessive reselection (ping-ponging) between layers. They do not control network registration eligibility (which depends on subscription and PLMN matching), transmit power limits (a separate RF parameter), or encryption key management (a security function handled through different mechanisms), but they play an important role in idle-mode load distribution and user experience from the moment a device wakes up.
