Nokia 5G RAN Network Operations Expert Sample Questions (Q46-Q51):

NEW QUESTION # 46
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: C

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 # 47
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?

Answer: B

Explanation:
'Locked' (administratively disabled) describes a deliberate, controlled state set by an operator or engineer - for example, intentionally taking a cell out of service for planned maintenance, an upgrade, or a configuration change window. This is an expected, reversible action: the cell can be 'unlocked' once the work is complete. 'Out of Service' due to a fault, by contrast, reflects an unintended operational failure - the cell was expected to be operating normally, but a fault condition (such as a hardware, transport, or synchronization issue) has prevented it from doing so, typically accompanied by one or more alarms.
Distinguishing these states matters for NOC engineers: a locked cell appearing down is expected and requires no fault investigation, whereas an unexpectedly out-of-service cell requires diagnosis. Neither state inherently relates to transmit power, and out-of-service conditions are not always due to software upgrades.


NEW QUESTION # 48
After successfully completing a significant remote configuration change on a base station and confirming normal operation, what additional lifecycle management step should the NOC team perform?

Answer: C

Explanation:
Once a significant configuration change has been successfully applied and verified - meaning the network element is operating normally with the new configuration in place - it is good practice to take an updated backup reflecting this new state. This becomes the new baseline restore point for any future changes, ensuring that if a subsequent change needs to be rolled back, the rollback target reflects the current, correct configuration rather than an outdated one that no longer matches the network element's intended state.
Restoring the previous backup immediately after a successful change would simply undo the work just completed, which is counterproductive. Deleting backups removes valuable recovery options and is contrary to good change management practice. Disabling the element's connection to NetAct would prevent the NOC from performing any future monitoring, fault management, or configuration activities on that element, which is operationally undesirable and unrelated to good post-change practice.


NEW QUESTION # 49
A 'High VSWR' (Voltage Standing Wave Ratio) alarm is raised on an RF unit's antenna branch. What does this alarm typically indicate a problem with?

Answer: C

Explanation:
Voltage Standing Wave Ratio (VSWR) measures how efficiently RF energy transmitted by the radio unit is delivered into the antenna system versus being reflected back due to an impedance mismatch. A High VSWR alarm indicates a significant mismatch on a particular antenna branch or port, commonly caused by issues such as a damaged or loose feeder cable connection, a faulty or improperly seated RF connector, moisture
/water ingress into a connector, or physical damage to an antenna element. This is a radio-frequency hardware issue on the affected branch and is entirely unrelated to NetAct server storage, core network mobility functions, or billing systems. For NOC engineers, a persistent High VSWR alarm typically signals that a field visit may be needed to inspect and repair the physical RF connections or replace damaged hardware on that antenna line, since it is a physical-layer condition not resolvable through remote configuration alone.


NEW QUESTION # 50
A NOC team needs to apply an identical parameter change - updating a neighbor relation threshold - across
200 cells in a region. What NetAct CM capability is best suited to perform this efficiently and consistently?

Answer: A

Explanation:
NetAct's Bulk Configuration Management capability, often referred to as Mass Update, is specifically designed for scenarios where the same configuration change needs to be applied consistently across a large number of network elements or cells. Rather than requiring an engineer to manually access each cell individually - which would be slow, error-prone, and difficult to audit - Bulk CM allows the target parameter, new value, and the set of affected cells to be defined once, with the change then propagated and applied consistently across all selected targets, typically with built-in logging and the ability to verify success or failure per element. This significantly reduces the time required for large-scale changes and ensures consistency, which is particularly important for parameters like neighbor relation thresholds where inconsistent configuration across a cluster could create uneven mobility behavior. Software Management's delivery function addresses SW lifecycle, not parameter changes, and Fault Management is unrelated to configuration provisioning.
