NEW QUESTION # 40
Which KPI category includes the RRC Connection Setup Success Rate, which reflects a UE's ability to successfully gain initial access to the network?
Answer: C
Explanation:
Accessibility KPIs measure a UE's ability to successfully access network services when requested. RRC (Radio Resource Control) Connection Setup Success Rate is a foundational accessibility metric in 4G/5G, representing the percentage of RRC connection setup attempts - the first step a UE takes to establish a radio connection with the gNB - that complete successfully. A high accessibility value indicates subscribers can reliably initiate sessions when they attempt to. This differs from Retainability, which measures whether already-established connections remain stable until normally released; Mobility, which assesses handover performance as UEs move between cells; and Integrity, which assesses the quality and throughput of an established connection. Because RRC setup is the entry point to accessing the network, its success rate falls within Accessibility, a category NOC engineers monitor closely to detect access-related problems caused by congestion, misconfiguration, or hardware faults preventing initial connections.
NEW QUESTION # 41
In NetAct's role-based access control model, which role would typically be assigned to a NOC engineer who needs to perform routine cell parameter and neighbor relation changes, but should NOT be able to modify user accounts or system-wide security settings?
Answer: D
Explanation:
NetAct's role-based access control allows different roles to be granted permission sets aligned with job responsibilities. An 'Operator' role with CM provisioning privileges is scoped to perform day-to-day configuration tasks - such as modifying cell parameters, neighbor relations, or power settings - without holding the broader privileges of a System Administrator, who manages user accounts, security policy, and overall NetAct system configuration. A Guest or read-only user can view alarms, performance reports, and configuration data but cannot make changes, so this role would prevent the engineer from performing the required provisioning tasks at all. A Database Administrator role focuses on the underlying database infrastructure supporting NetAct rather than RAN configuration provisioning. Assigning an Operator role with CM privileges follows the least-privilege principle: the engineer receives exactly the access required to perform routine provisioning, and nothing more.
NEW QUESTION # 42
Which NetAct functional area provides tools that allow an operator to apply the same parameter change consistently to multiple AirScale base stations or cells in a single operation?
Answer: A
Explanation:
NetAct's Configuration Management (CM) area provides bulk/mass update capabilities that let an operator define a parameter change once - such as updating a neighbor relation, adjusting a power parameter, or enabling a feature - and apply it consistently across many base stations or cells in a single, auditable operation. This is fundamental to standard provisioning tasks covered in remote operations, allowing large- scale configuration rollouts without logging into each element individually, while maintaining consistency and an audit trail of who changed what and when. Fault Management focuses on collecting, displaying, and correlating alarms rather than making configuration changes. Performance Management focuses on collecting and reporting KPI/counter data. Software Management can distribute and activate software packages across multiple base stations, but it does not handle parameter and configuration provisioning, which is the specific domain of Configuration Management's bulk operations tools.
NEW QUESTION # 43
After a field engineer physically replaces a Remote Electrical Tilt (RET) antenna actuator, what remote verification should the NOC engineer perform to confirm the new unit is properly integrated?
Answer: D
Explanation:
Remote Electrical Tilt (RET) units are Antenna Line Devices (ALDs) that communicate with the base station over the Antenna Interface Standards Group (AISG) bus. After a physical RET replacement, the appropriate remote verification is to confirm that the new device is discovered on the AISG bus, that it is communicating correctly with the base station's controller, and that its current tilt position can be read remotely and that tilt adjustment commands are correctly applied and reflected back. This confirms both the physical connectivity (cabling/bus communication) and functional operability (motor and position feedback) of the replaced unit.
The unit's color is irrelevant to functional verification, and while serial number changes are expected with replacement (a new unit will naturally have a different serial number, which should simply be recorded for inventory purposes), it is not itself a functional check. NR-ARFCN relates to radio carrier frequency configuration and has no relationship to RET device verification.
NEW QUESTION # 44
When planning a maintenance window for a software activation affecting multiple cells at a site, which factor is most important for the NOC team to consider in order to minimize subscriber impact?
Answer: D
Explanation:
Because software activation typically requires affected cells to restart, briefly interrupting service for any actively connected UEs, the most important factor in selecting a maintenance window is identifying a time period when traffic at the site is at its lowest, based on historical traffic pattern analysis. Sites can have different busy-hour profiles depending on their location and the population they serve - for example, a site near a business district may have low traffic late at night, while a site in a residential entertainment area might have different patterns - so generic assumptions about 'off-peak' hours should ideally be validated against actual historical data for that specific site. Software version numbers, PLMN IDs, and current alarm counts have no inherent relationship to traffic levels and should not be used as proxies for determining the best maintenance window; traffic pattern data is the relevant and reliable input for this planning decision.
