12. Frage
Which KPI category does the RRC Connection Setup Success Rate primarily belong to, and what does a sustained drop in this KPI typically indicate?
Antwort: B
Begründung:
The RRC Connection Setup Success Rate is one of the primary Accessibility KPIs, measuring how reliably User Equipment (UE) can successfully establish a Radio Resource Control connection with the network when attempting to access services. A sustained decline in this KPI indicates that a meaningful proportion of connection attempts are failing before the UE even reaches an active signaling state, which directly impacts a subscriber's ability to begin a session. Common causes include radio interference, congestion-related admission control rejections, configuration errors affecting random access or initial signaling parameters, or hardware faults on the baseband or RF units. This differs from Mobility KPIs (which assess handover performance for already-connected UEs), Integrity KPIs (which assess throughput and quality during an active session), and Availability KPIs (which assess whether the cell itself is in service). Accessibility issues should be prioritized since they affect every subscriber attempting to use the cell.

What operational benefit does the Automatic Neighbor Relation (ANR) function provide to a NOC team managing 5G RAN configuration?
Antwort: D
Begründung:
The Automatic Neighbor Relation (ANR) function reduces the manual configuration burden associated with maintaining accurate neighbor lists across a large RAN by using UE measurement reports to detect cells that UEs can actually see and successfully measure in the field. When a UE reports a previously unconfigured neighboring cell with sufficient signal quality, ANR can automatically add the appropriate neighbor relation (and, where applicable, retrieve the necessary identification information for that neighbor) so that future handovers toward that cell can be evaluated and executed. This is particularly valuable in dense, frequently changing network environments where manually planning every neighbor relation - especially across vendor or technology boundaries - would be time-consuming and error-prone. ANR does not address hardware faults, PLMN configuration, or transmit power adjustments, which are governed by separate fault management and RF parameter processes respectively, but it significantly improves the completeness and accuracy of neighbor relation databases that mobility KPIs depend on.
14. Frage
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)?
Antwort: C
Begründung:
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.
15. Frage
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?
Antwort: D
Begründung:
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.
16. Frage
Which NetAct Fault Management view should a NOC engineer use to see alarms that are currently outstanding and affecting the network, as opposed to alarms that have already been resolved?
Antwort: C
Begründung:
The Active Alarms list in NetAct Fault Management displays alarms that are currently outstanding (uncleared) and affecting the network in real time, making it the primary view NOC engineers monitor to identify ongoing issues requiring attention and to prioritize response based on severity. The Alarm History
/Log, in contrast, contains records of past alarms - including those already cleared - which is useful for trend analysis, post-incident reviews, and identifying recurring or intermittent faults over time, but is not the appropriate view for real-time triage of current network health. PM Reports relate to performance counters and KPI trends, not fault/alarm conditions, and the Software Inventory view shows deployed software versions across elements rather than fault information. For day-to-day monitoring and prioritizing immediate response efforts, the Active Alarms list is the correct view.
