質問 # 25
Why does Nokia recommend configuring automatic session timeout (inactivity logout) for remote management sessions to AirScale base stations?
正解：C
解説：
Automatic session timeout is a fundamental security control for remote management sessions. If an engineer leaves an authenticated session open and unattended - for example, stepping away from a workstation - anyone with physical or logical access to that workstation could potentially view sensitive configuration data or, more seriously, make unauthorized changes to a live base station, which could impact network stability, security, or subscriber service. Automatically terminating idle sessions after a defined inactivity period minimizes this exposure window. This control is unrelated to site power consumption and does not cause the base station itself to restart - only the management session is closed, while the BTS continues normal operation. It also has no effect on a cell's radio coverage area, which is determined entirely by RF design and configuration parameters such as transmit power and antenna settings.
質問 # 26
What is a 'threshold crossing alert' (TCA), and how does it differ from a standard equipment fault alarm?
正解：C
解説：
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.
質問 # 27
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?
正解：D
解説：
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.
質問 # 28
A KPI tracks the percentage of established connections or sessions that end abnormally ('dropped') rather than through a normal release procedure. Which KPI category does this belong to?
正解：C
解説：
Retainability KPIs measure whether connections or sessions that have been successfully established remain stable and are terminated through normal procedures, rather than ending abnormally (a 'drop'). A high abnormal release/drop rate indicates retainability problems - subscribers may experience calls or data sessions ending unexpectedly mid-use, significantly impacting user experience even when the initial connection (accessibility) succeeded. This differs from Accessibility, which measures the success of the initial connection attempt; Mobility, which specifically measures handover performance; and Availability, which measures whether a cell or site is in service over time. Retainability degradation can result from radio link failures, interference, transport instability, or hardware issues affecting an already-active connection. NOC engineers monitoring retainability KPIs focus on the stability of in-progress sessions, a key contributor to overall subscriber-perceived quality of service.
質問 # 29
Before rolling out a new software release across an entire region's base stations, an operator first activates it on a small subset of sites and closely monitors their performance for a period of time. What is this practice commonly called, and what is its primary benefit?
正解：C
解説：
A staged or pilot rollout - sometimes referred to as a canary deployment - involves activating a new software release on a small, representative subset of sites first, then closely monitoring key indicators such as alarms, KPIs, and overall stability for a defined observation period before proceeding with wider deployment. The primary benefit of this approach is risk containment: if the new software introduces an unforeseen issue - whether a compatibility problem, a performance regression, or an unexpected interaction with certain configurations - the impact is limited to the pilot sites rather than the entire region, allowing the issue to be identified and addressed (potentially by halting further rollout) before it affects a much larger portion of the network. This practice is a software lifecycle risk-management technique and is unrelated to factory resets, configuration audits focused on PLMN consistency, or bulk parameter updates, which serve entirely different operational purposes.
