NEW QUESTION # 64
During a complex remote piloting activity involving multiple steps and risk of service impact, what additional coordination practice helps ensure accountability and a clear record of what was agreed and performed at each stage?
Answer: C
Explanation:
For complex, multi-step remote piloting activities with potential service impact, using a shared communication channel - such as a bridge call or a logged chat/messaging channel - where each step, its confirmation, and its result are recorded in real time provides significant benefits. It creates a contemporaneous record of exactly what was instructed, performed, and confirmed at each stage, which supports accountability (clarifying who performed or authorized each action) and provides an accurate timeline that can be referenced if an issue arises during or after the activity, or if the activity needs to be reviewed afterward for process improvement. This is in addition to, not a replacement for, the final documentation in the maintenance ticket. Avoiding real-time communication would undermine the collaborative coordination that complex activities require; anonymous channels would defeat the accountability purpose; and performing steps simultaneously without sequencing would be unsafe and likely to cause errors, particularly where later steps depend on the successful completion of earlier ones.
NEW QUESTION # 65
What does the NR-ARFCN (NR Absolute Radio Frequency Channel Number) represent in a 5G cell's configuration?
Answer: B
Explanation:
The NR Absolute Radio Frequency Channel Number (NR-ARFCN) is a standardized numbering scheme defined for 5G NR that maps specific numeric values to corresponding carrier frequencies across the supported frequency range. When configuring a cell, the NR-ARFCN value (rather than specifying the frequency directly in MHz) is used to unambiguously identify the exact carrier frequency the cell will operate on, ensuring consistency across equipment from different vendors and alignment with regulatory frequency allocations. Correct NR-ARFCN configuration is essential for frequency planning, neighbor relation setup (since inter-frequency relations reference the target cell's frequency), and avoiding interference with adjacent operators or bands. This parameter is unrelated to subscriber database identifiers, alarm counts, or PRB utilization, all of which are tracked through entirely separate configuration management, fault management, or performance management mechanisms respectively.
NEW QUESTION # 66
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: C
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 # 67
Which statement correctly distinguishes 'Integrity' KPIs from 'Accessibility' KPIs in RAN performance management?
Answer: D
Explanation:
Accessibility KPIs measure how successfully a UE can initially establish a connection or session when it attempts to do so - for example, RRC Connection Setup Success Rate. Integrity KPIs, by contrast, measure the quality and performance of a connection once it has been successfully established - for example, achievable throughput, latency, or error rates during an active session. These represent two distinct stages of user experience: first, can the user connect at all (Accessibility), and second, once connected, how good is the service (Integrity)? They are not the same category measured differently, since they address fundamentally different performance aspects and often require different troubleshooting approaches - accessibility issues often relate to admission and signaling procedures, while integrity issues often relate to radio conditions, interference, or capacity affecting data transfer. Integrity KPIs apply across all radio generations including
5G, and Accessibility is not limited solely to throughput.
NEW QUESTION # 68
A cell consistently shows PRB utilization above 90% during peak hours, along with a rising number of RRC Connection Rejections due to insufficient resources. What does this combination of indicators most strongly suggest?
Answer: C
Explanation:
Sustained PRB utilization above roughly 90% indicates that nearly all available radio resources in the cell are being consumed, leaving little headroom for new connections or additional traffic. When this is combined with an increasing rate of RRC Connection Rejections specifically attributed to insufficient resources, it strongly indicates that the cell's admission control function is actively rejecting new connection attempts because demand exceeds available capacity - a clear signature of capacity congestion during busy periods.
This is fundamentally different from a hardware fault (which would typically generate equipment alarms and affect availability rather than just capacity), a synchronization loss (which affects timing-sensitive operations and often triggers specific sync alarms), or a neighbor relation issue (which would primarily affect mobility KPIs). Recognizing this pattern is important because it points toward capacity planning actions - such as carrier expansion, load balancing, or additional sectorization - rather than fault remediation.
