質問 # 92
During PCI planning for a dense cluster of 5G cells, why is it important to avoid assigning PCI values that result in the same PCI modulo group (such as the same PCI mod 3 value) to closely located neighboring cells?
正解：C
解説：
The Physical Cell Identity has mathematical relationships - such as PCI mod 3 and PCI mod 30 - that determine which specific resource elements certain reference signal sequences are mapped to within the radio frame. When two closely located, mutually visible cells share the same PCI mod 3 group, their reference signals for that group occupy the same time-frequency resources, increasing the likelihood of mutual interference on those reference signals. This can degrade channel estimation and measurement accuracy for UEs near the cell edge between the two cells, indirectly impacting handover performance and link quality.
Careful PCI planning therefore considers not just avoiding direct PCI collisions (identical PCI on neighbors) but also distributing PCI mod group assignments across a cluster to minimize this reference signal overlap.
PCI mod values have no bearing on software versioning, bandwidth limits, or Tracking Area grouping, which are configured through entirely separate parameters.

How does applying a software patch typically differ from performing a full software upgrade on a base station?
正解：A
解説：
A software patch is typically a smaller, targeted update designed to address specific known issues, bugs, or vulnerabilities within the currently running software baseline, without changing the overall feature set or version baseline significantly. Patches are often quicker to apply and may have a more limited scope of impact, making them suitable for addressing urgent issues between major release cycles. A full software upgrade, by contrast, replaces the base station's overall software load with a new baseline release, which may introduce new features, performance improvements, and an accumulated set of fixes - representing a more significant change that typically requires more thorough planning, testing, and a more comprehensive pre-change backup. Both patches and full upgrades can generally be delivered and activated remotely without requiring physical hardware replacement. Understanding this distinction helps NOC teams appropriately scope the risk, testing, and scheduling considerations for each type of software lifecycle activity.

A field engineer needs to work in close proximity to an antenna to replace a Tower Mounted Amplifier (TMA). What is the NOC engineer's most important responsibility before the field engineer begins this work?
正解：D
解説：
When a field engineer needs to work in close physical proximity to an antenna - such as when replacing a Tower Mounted Amplifier - radio frequency (RF) exposure becomes a safety consideration, since active transmission from the antenna could expose the engineer to RF energy levels exceeding safe limits at close range. The NOC engineer's most important responsibility in this scenario is to coordinate placing the affected cell's RF transmission into a safe state - typically by locking the cell - before the field engineer begins work near the antenna, and to confirm this state is in place before giving the go-ahead. This directly supports the field engineer's physical safety. Increasing transmit power would worsen RF exposure risk and is the opposite of the correct action; scheduling for busy hours is irrelevant to the safety requirement and would also affect more subscribers; and disabling alarm notifications would reduce the NOC's situational awareness during the activity without providing any safety benefit.

What is the role of the Managed Object Model (MOM) in Nokia's RAN configuration management framework?
正解：D
解説：
The Managed Object Model (MOM) defines the structured, hierarchical representation of all configurable entities within the network - such as network elements, their subordinate functional units, cells, and the individual parameters associated with each object - along with the relationships between them. Configuration management tools, including NetAct CM applications, rely on the MOM to know what objects exist, what parameters each object type supports, valid value ranges, and how objects relate to one another (for example, a cell object existing as a child of a baseband equipment object). Understanding the MOM is important for NOC engineers performing configuration changes, since it determines where a given parameter resides within the object hierarchy and what other objects or parameters might be affected by a change. The MOM is a configuration management construct and is unrelated to physical cabling documentation, alarm history (a fault management function), or software upgrade packages (a software lifecycle management function).
質問 # 96
In NetAct Performance Management, what is a 'measurement job'?
正解：D
解説：
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.
