NEW QUESTION # 18
A NOC engineer 'acknowledges' an active alarm in NetAct FM. What does this action signify?
Answer: B
Explanation:
Acknowledging an alarm in NetAct FM is an administrative action that marks the alarm as having been seen and taken ownership of by an engineer, without changing the underlying fault condition itself. In a NOC environment where multiple engineers or shifts monitor shared alarm lists, acknowledgement communicates that someone is already aware of and working on the issue, helping to avoid duplicated troubleshooting effort and providing a basic accountability trail for follow-up. It does not automatically resolve or repair the underlying fault - the alarm will only clear once the actual condition causing it is resolved, whether automatically by the network recovering or through engineer intervention. Acknowledgement also does not cause the base station to reboot, and acknowledged alarms remain visible in the active list (not deleted) until the underlying condition clears, at which point they typically move to the alarm history.
NEW QUESTION # 19
Why does NetAct support configuring automatic notifications, such as email or SMS, for Critical severity alarms to NOC personnel?
Answer: A
Explanation:
NetAct supports configuring automatic notifications, such as email or SMS alerts, to be sent to designated NOC personnel when alarms of a certain severity - commonly Critical - are raised. This ensures severe issues are brought to the attention of responsible engineers promptly, even if no one is actively viewing the live FM dashboard at that exact moment, helping reduce the time between a fault occurring and corrective action beginning. This notification mechanism complements, rather than replaces, the FM dashboard, which remains necessary for detailed investigation, alarm correlation across the network, and ongoing monitoring of all severity levels. It does not automatically fix any underlying fault - it is purely an awareness mechanism - and has no effect on how many alarms the network actually generates, which is determined by real fault conditions and configured alarm definitions/thresholds, not by notification settings.
NEW QUESTION # 20
When planning the channel bandwidth and subcarrier spacing for a 5G cell, what is the primary operational impact of these parameters?
Answer: B
Explanation:
Channel bandwidth and subcarrier spacing are fundamental radio configuration parameters that together determine how many Physical Resource Blocks (PRBs) are available within a cell's carrier. Since PRBs are the basic units of radio resource that the scheduler allocates to UEs for both downlink and uplink transmissions, the number of available PRBs directly determines the cell's theoretical capacity - that is, how much traffic the cell can serve simultaneously before becoming congested. A wider channel bandwidth provides more PRBs and therefore greater capacity, while subcarrier spacing affects the size of each PRB in the frequency domain and has implications for latency and mobility performance at different frequency ranges. These parameters are foundational to capacity planning and must be configured consistently with the operator's spectrum holdings and regulatory allocations. They have no bearing on PLMN/TAC identifiers, alarm severity configuration, or O and M transport security, which are governed by entirely separate configuration domains.
NEW QUESTION # 21
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: D
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 # 22
Before performing a remote software upgrade on a base station, what should a NOC engineer ensure has been completed regarding the site's current state?
Answer: B
Explanation:
Taking and verifying a current configuration and software backup before a remote software upgrade is a fundamental pre-upgrade step. This backup captures the site's known-working state - including its current software load and configuration parameters - immediately before changes are introduced. If the upgrade fails, results in unexpected behavior, or the automatic fallback mechanism does not fully restore normal operation, this backup provides a verified restore point that the NOC can use to recover the site to its prior working condition, minimizing downtime and avoiding the need for a more disruptive recovery process such as a full re-commissioning. Deleting alarm history, changing the PLMN ID, or removing neighbor relations are not standard or appropriate pre-upgrade steps; they would either destroy useful troubleshooting history, disrupt subscriber service through incorrect network identification, or unnecessarily degrade mobility performance, none of which relate to safely preparing for a software upgrade.
