NEW QUESTION # 96
A NOC team needs to apply an identical parameter change - updating a neighbor relation threshold - across
200 cells in a region. What NetAct CM capability is best suited to perform this efficiently and consistently?
Answer: C
Explanation:
NetAct's Bulk Configuration Management capability, often referred to as Mass Update, is specifically designed for scenarios where the same configuration change needs to be applied consistently across a large number of network elements or cells. Rather than requiring an engineer to manually access each cell individually - which would be slow, error-prone, and difficult to audit - Bulk CM allows the target parameter, new value, and the set of affected cells to be defined once, with the change then propagated and applied consistently across all selected targets, typically with built-in logging and the ability to verify success or failure per element. This significantly reduces the time required for large-scale changes and ensures consistency, which is particularly important for parameters like neighbor relation thresholds where inconsistent configuration across a cluster could create uneven mobility behavior. Software Management's delivery function addresses SW lifecycle, not parameter changes, and Fault Management is unrelated to configuration provisioning.
NEW QUESTION # 97
A 'High VSWR' (Voltage Standing Wave Ratio) alarm is raised on an RF unit's antenna branch. What does this alarm typically indicate a problem with?
Answer: C
Explanation:
Voltage Standing Wave Ratio (VSWR) measures how efficiently RF energy transmitted by the radio unit is delivered into the antenna system versus being reflected back due to an impedance mismatch. A High VSWR alarm indicates a significant mismatch on a particular antenna branch or port, commonly caused by issues such as a damaged or loose feeder cable connection, a faulty or improperly seated RF connector, moisture
/water ingress into a connector, or physical damage to an antenna element. This is a radio-frequency hardware issue on the affected branch and is entirely unrelated to NetAct server storage, core network mobility functions, or billing systems. For NOC engineers, a persistent High VSWR alarm typically signals that a field visit may be needed to inspect and repair the physical RF connections or replace damaged hardware on that antenna line, since it is a physical-layer condition not resolvable through remote configuration alone.
NEW QUESTION # 98
What is a 'threshold crossing alert' (TCA), and how does it differ from a standard equipment fault alarm?
Answer: B
Explanation:
A threshold crossing alert (TCA) is generated when a monitored performance counter or KPI - such as PRB utilization, processor load, or a quality metric - crosses an operator-configured threshold value, providing visibility into a performance-related condition that may or may not correspond to an actual hardware fault.
For example, sustained high PRB utilization on a cell might trigger a TCA flagging a capacity concern, prompting capacity planning or optimization actions, even though no equipment has failed. This differs fundamentally from a standard equipment fault alarm, which is raised in direct response to a detected hardware or communication failure condition. TCAs are configurable by the operator, allowing thresholds to be tuned to the network's specific performance targets and capacity planning needs, and they are not limited to software license conditions, nor are they fixed, unconfigurable values.
NEW QUESTION # 99
Some alarms in NetAct FM clear automatically once the underlying fault condition no longer exists, while others require manual clearing by an engineer. What characterizes an alarm that requires manual clearing?
Answer: B
Explanation:
Many alarms in NetAct FM are designed to self-clear: once the network element detects that the underlying condition no longer exists - for example, a transient link flap recovering on its own - the element sends a clear notification and the alarm is automatically removed from the active list. However, some alarms represent conditions where the element cannot reliably self-verify resolution, such as certain hardware faults requiring physical intervention, or conditions tied to actions needing human confirmation. These alarms may remain active even after corrective action has been taken, until an engineer manually clears them or the system completes a subsequent successful self-test. NOC engineers need to understand this distinction so the active alarm list accurately reflects current network status, and so that manual clearing is correctly performed as part of completing a maintenance action where required.
NEW QUESTION # 100
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: B
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.
