What is the purpose of license management functionality within NetAct as it relates to base station software and features?

• A. It tracks the physical inventory of spare RF cables stored at each site
• B. It manages the PLMN IDs assigned to each base station
• C. 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
• D. It schedules routine site cleaning and maintenance visits

An operator is considering reducing the PM Result Output Period (ROP) for a set of cells from 15 minutes to
1 minute to enable near real-time troubleshooting. What is the most significant operational trade-off of this change?

• A. Shorter ROPs automatically disable all alarm notifications for the affected cells
• B. Shorter ROPs significantly increase the volume of measurement data generated and the load on collection and storage systems
• C. Shorter ROPs prevent NetAct from displaying any historical performance trends
• D. Shorter ROPs make KPI formulas invalid and unusable

An 'Equipment Over-Temperature' alarm is raised at a remote site. Besides checking the cooling system itself, what else should a NOC engineer review related to this alarm?

• A. Whether a cabinet door-open, fan failure, or HVAC/air-conditioning fault alarm is also present, indicating a broader environmental issue
• B. The cell's configured Physical Cell Identity (PCI)
• C. The handover success rate KPI
• D. The NetAct software license expiry date

A base station has the necessary software installed to support a new advanced scheduling feature, but the feature remains inactive. The NOC engineer is informed that a license-related step is required. What is the most likely explanation?

• A. Many advanced features require a valid license key to be activated in addition to having the supporting software installed, separating software capability from commercial entitlement
• B. The feature can only be activated by physically replacing the baseband module
• C. The feature will activate automatically once the next scheduled software upgrade occurs, regardless of licensing
• D. The feature requires a software downgrade before it can be used

What is the role of the Managed Object Model (MOM) in Nokia's RAN configuration management framework?

• A. It is the software package used to upgrade base station firmware
• B. It is a list of all active and historical alarms for a network element
• C. It defines the physical cabling diagram for a base station site
• D. It defines the structured hierarchy of configurable objects (such as network elements, cells, and their parameters) that configuration management tools operate on
