Nokia 5G RAN Network Operations Expert Sample Questions (Q109-Q114):

NEW QUESTION # 109
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: A

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 # 110
After exhausting standard remote troubleshooting steps for a persistent Major alarm that remains unresolved, what is the appropriate NOC action?

Answer: D

Explanation:
When standard remote troubleshooting steps for a persistent Major alarm have been exhausted without resolution, the appropriate NOC action is to follow the organization's defined escalation procedures - this may involve escalating to a higher-tier technical support team, a specialist engineering group, or field operations for a possible site visit, depending on the nature of the fault. Critically, the engineer should document the troubleshooting steps already performed, observations made, and relevant data gathered (alarm history, performance data, configuration checks), so the receiving team can proceed efficiently without repeating completed work. Ignoring the alarm leaves a genuine network issue unaddressed and risks breaching service level agreements. Deleting the alarm from NetAct does not resolve the underlying fault and removes valuable diagnostic history. Locking all cells across the entire network is a drastic, disproportionate action that would itself cause a massive outage and is never an appropriate response to a single persistent alarm.


NEW QUESTION # 111
When planning the channel bandwidth and subcarrier spacing for a 5G cell, what is the primary operational impact of these parameters?

Answer: D

Explanation:
Channel bandwidth and subcarrier spacing are fundamental radio configuration parameters that together determine how many Physical Resource Blocks (PRBs) are available within a cell's carrier. Since PRBs are the basic units of radio resource that the scheduler allocates to UEs for both downlink and uplink transmissions, the number of available PRBs directly determines the cell's theoretical capacity - that is, how much traffic the cell can serve simultaneously before becoming congested. A wider channel bandwidth provides more PRBs and therefore greater capacity, while subcarrier spacing affects the size of each PRB in the frequency domain and has implications for latency and mobility performance at different frequency ranges. These parameters are foundational to capacity planning and must be configured consistently with the operator's spectrum holdings and regulatory allocations. They have no bearing on PLMN/TAC identifiers, alarm severity configuration, or O and M transport security, which are governed by entirely separate configuration domains.


NEW QUESTION # 112
What is the key distinction between a full site backup and a partial (configuration-only) backup in the context of base station lifecycle management?

Answer: D

Explanation:
A full site backup typically captures both the currently running software load (or a reference to it) and the complete configuration data for the network element, providing the most comprehensive restore point - useful before major changes such as software upgrades or significant hardware-related maintenance. A partial, or configuration-only, backup captures just the configuration data - the set of parameters defining how the element is provisioned - without necessarily including the software image itself. Configuration-only backups are commonly used before smaller-scope parameter changes, where the software load itself is not expected to change, since they are typically faster to perform and require less storage. Choosing the appropriate backup type depends on the scope of the planned change: a software upgrade warrants a full backup, while a routine parameter adjustment may only require a configuration backup. Neither backup type is restricted to alarm history or performance counters, and both can typically be performed remotely without requiring a field engineer to be present.


NEW QUESTION # 113
A NOC engineer observes an 'alarm storm' - dozens of alarms appearing within seconds across multiple cells served by the same site. What is the MOST likely explanation?

Answer: A

Explanation:
An 'alarm storm' - many alarms appearing across multiple cells at a single site within a short window - is a classic indicator that a shared resource serving all of those cells has failed. Multiple cells at a site commonly depend on the same System Module (baseband), the same transport connection back to the aggregation/core network, the same power supply, or the same synchronization source; a failure in any one of these shared elements can simultaneously impact every dependent cell, producing a burst of correlated alarms.
Recognizing this pattern allows the NOC engineer to search for a single common-cause fault - for example, a transport outage or System Module failure - rather than treating each cell's alarms as independent issues requiring separate investigation. It is extremely unlikely that multiple independent hardware faults occur simultaneously by coincidence, and such patterns should never be dismissed as a routine NetAct bug or simply ignored.
