Nokia 5G RAN Network Operations Expert Sample Questions (Q115-Q120):

NEW QUESTION # 115
During a remote piloting session, what communication practice is most important for the NOC engineer and field engineer to follow to ensure tasks are completed safely and correctly?

Answer: C

Explanation:
Effective remote piloting depends on clear, step-by-step communication where each action - whether performed by the field engineer physically or the NOC engineer remotely - is confirmed as complete before the next dependent step proceeds. This sequential confirmation approach ensures that both parties maintain an accurate, shared understanding of the site's current state at every point in the procedure, which is critical for both safety (for example, confirming a cell is locked before physical work begins near an antenna) and technical correctness (for example, confirming a physical connection has been made before the NOC engineer attempts to verify it remotely). Providing all instructions upfront without ongoing confirmation risks steps being missed, performed out of order, or performed before prerequisite conditions are met. Relying solely on non-real-time communication such as email is impractical for time-sensitive coordination, and allowing the field engineer to proceed entirely independently removes the collaborative verification that makes remote piloting effective and safe.


NEW QUESTION # 116
What is the standard alarm severity ordering used in NetAct Fault Management, from highest to lowest severity?

Answer: C

Explanation:
NetAct Fault Management follows the standard telecom alarm severity hierarchy: Critical, Major, Minor, and Warning, in descending order of severity. Critical alarms indicate a total or near-total loss of service, capability, or capacity, requiring immediate NOC action since they have the most severe impact on network availability and subscribers. Major alarms indicate serious degradation requiring prompt action, though typically with somewhat less urgency than Critical. Minor alarms represent non-service-affecting faults that should still be corrected to prevent future escalation into more serious issues. Warning alarms are generally informational or preventive, flagging conditions that could lead to a problem if left unaddressed but with no current service impact. Understanding this ordering is fundamental to NOC triage and prioritization: when multiple alarms appear on a dashboard, Critical alarms must be addressed first, followed by Major, Minor, and finally Warning, and this ordering underlies SLA-based response time commitments.


NEW QUESTION # 117
Which AirScale management tool allows an engineer to connect directly to a single base station for local-level configuration viewing and diagnostics, as opposed to network-wide centralized management?

Answer: A

Explanation:
The BTS Site Manager, also referred to as the local Element Manager, is the tool used to connect directly to an individual AirScale base station to view its local configuration, hardware inventory, logs, and run element- level diagnostics. It is typically used when an engineer needs granular, site-specific information that may not be fully visible through the centralized system, or when NetAct connectivity to the site is impaired. NetAct CM Editor is used for network-wide configuration management of many sites from the central OSS, NetAct PM Reports aggregates performance counters across the network, and the SON Network Optimizer automates parameter tuning across multiple cells. Because the question specifically asks about direct, single-element access for local diagnostics rather than network-wide operations, the BTS Site Manager is the correct answer, complementing NetAct in a complete remote operations toolkit.


NEW QUESTION # 118
What does the NR-ARFCN (NR Absolute Radio Frequency Channel Number) represent in a 5G cell's configuration?

Answer: D


NEW QUESTION # 119
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.
