NEW QUESTION # 17
In NetAct Performance Management, what is a 'measurement job'?
Answer: C
Explanation:
In NetAct Performance Management, a 'measurement job' is a configured task that specifies which performance counters or KPIs should be collected, from which network elements (such as specific base stations or cells), and at what collection interval - for example, every 15 minutes or hourly. These jobs are the mechanism by which raw counter data is gathered from the RAN and made available for KPI calculation, reporting dashboards, and threshold-based alerting. Without properly configured measurement jobs covering the relevant counters and elements, the performance data needed to assess network health and detect KPI degradation would simply not be collected. This is distinct from a field technician's scheduled maintenance task, a software upgrade package (a Software Management concept), or a user account (an access control concept) - a measurement job specifically governs the automated, ongoing collection of performance statistics within the PM functional area.
NEW QUESTION # 18
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 # 19
A NOC engineer observes an 'alarm storm' - dozens of alarms appearing within seconds across multiple cells served by the same site. What is the MOST likely explanation?
Answer: A
Explanation:
An 'alarm storm' - many alarms appearing across multiple cells at a single site within a short window - is a classic indicator that a shared resource serving all of those cells has failed. Multiple cells at a site commonly depend on the same System Module (baseband), the same transport connection back to the aggregation/core network, the same power supply, or the same synchronization source; a failure in any one of these shared elements can simultaneously impact every dependent cell, producing a burst of correlated alarms.
Recognizing this pattern allows the NOC engineer to search for a single common-cause fault - for example, a transport outage or System Module failure - rather than treating each cell's alarms as independent issues requiring separate investigation. It is extremely unlikely that multiple independent hardware faults occur simultaneously by coincidence, and such patterns should never be dismissed as a routine NetAct bug or simply ignored.
NEW QUESTION # 20
After exhausting standard remote troubleshooting steps for a persistent Major alarm that remains unresolved, what is the appropriate NOC action?
Answer: D
Explanation:
When standard remote troubleshooting steps for a persistent Major alarm have been exhausted without resolution, the appropriate NOC action is to follow the organization's defined escalation procedures - this may involve escalating to a higher-tier technical support team, a specialist engineering group, or field operations for a possible site visit, depending on the nature of the fault. Critically, the engineer should document the troubleshooting steps already performed, observations made, and relevant data gathered (alarm history, performance data, configuration checks), so the receiving team can proceed efficiently without repeating completed work. Ignoring the alarm leaves a genuine network issue unaddressed and risks breaching service level agreements. Deleting the alarm from NetAct does not resolve the underlying fault and removes valuable diagnostic history. Locking all cells across the entire network is a drastic, disproportionate action that would itself cause a massive outage and is never an appropriate response to a single persistent alarm.
NEW QUESTION # 21
A field team is planning a site visit to investigate a persistent coverage issue and requests information from the NOC to help prepare. What information can the NOC engineer most usefully provide to support this site survey?
Answer: D
Explanation:
When a field team is preparing to investigate a persistent coverage issue, remotely available operational data can significantly improve the efficiency and focus of their site visit. The NOC engineer can provide the current configuration of the affected cell (including parameters such as transmit power, tilt settings, and azimuth where available), a review of recent alarm history to identify any recurring or unresolved fault indications, and relevant performance data such as RSRP/SINR distributions and throughput trends, which can help characterize the nature of the coverage issue (for example, distinguishing a coverage gap from an interference problem) before the field team arrives. This context allows the field team to prioritize their investigation - for example, focusing on antenna alignment if tilt/azimuth data looks unusual, or focusing on potential external interference sources if SINR is poor despite adequate RSRP. Subscriber personal information, equipment purchase records, and data about unrelated sites would not provide relevant technical context for this investigation.
