NEW QUESTION # 11
Within NetAct, which functional module is primarily responsible for planning, distributing, and activating software packages across base stations?
Answer: B
Explanation:
The Software Management (SWM) module within NetAct is the centralized functional area responsible for the end-to-end software lifecycle of base stations and other network elements, including planning software deployment campaigns, distributing (downloading) software packages to target network elements, scheduling and triggering activation, and monitoring the success or failure of these operations across potentially large numbers of sites. This is distinct from Fault Management (FM), which handles alarms and fault conditions; Performance Management (PM), which handles KPI and counter-based performance data; and Configuration Management (CM), which handles parameter and configuration provisioning. While these modules may interact - for example, a software activation might generate alarms visible in FM, or a software change might necessitate subsequent configuration adjustments via CM - the core responsibility for managing software packages, versions, and activation campaigns rests specifically with SWM, making it the primary tool a NOC engineer would use for software lifecycle activities.
NEW QUESTION # 12
What is the primary purpose of the secure IPsec VPN tunnel established between a centralized Operations Center and a remote 5G site's transport network?
Answer: C
Explanation:
Centralized Operations Centers connect to many geographically distributed 5G sites over shared transport infrastructure that may include third-party or public network segments. A secure tunnel, typically using IPsec, is established between the Operations Center's management domain and the site's security gateway to encrypt and authenticate all Operations, Administration, and Maintenance (O and M) traffic - including configuration commands, alarm and performance data, and software transfers - protecting it from interception, tampering, or unauthorized access. This secure channel has no effect on RF transmit power, which is governed by separate cell configuration parameters, and it does not perform software compression, which is a function of the software packaging process itself. It also does not replace alarm monitoring, which is handled by NetAct's Fault Management module; rather, the VPN ensures that alarm data itself reaches the Operations Center securely.
NEW QUESTION # 13
When configuring NR-NR (5G-to-5G) neighbor relations to support mobility between two 5G cells operating on different frequency bands, which type of neighbor relation must be established?
Answer: B
Explanation:
When two 5G NR cells operate on different frequency bands (or different carrier frequencies within the same band), mobility between them requires an inter-frequency neighbor relation to be configured. This relation must include the necessary frequency information identifying the target carrier, along with measurement configuration parameters that instruct the UE when and how to measure the candidate target frequency - since, unlike intra-frequency measurements, inter-frequency measurements typically require measurement gaps and are not performed continuously by the UE. An intra-frequency neighbor relation would only be appropriate if both cells operated on the same carrier frequency, which is not the case here. Inter-band 5G-to-
5G handovers are not automatic without configuration; the network must explicitly define the relation and measurement parameters to enable the UE to detect and report the target cell. EN-DC relations are specifically for LTE-NR dual connectivity scenarios and are unrelated to NR-NR mobility between two 5G cells.
NEW QUESTION # 14
A NOC engineer is considering performing a remote factory reset on a base station as a troubleshooting step for a persistent issue. What is the most significant risk of this action if performed without proper preparation?
Answer: B
Explanation:
A factory reset typically returns a network element to its default, out-of-the-box configuration state, which generally means erasing the unit's current operational configuration - including cell parameters, neighbor relations, and other site-specific provisioning. If performed without first ensuring a verified, complete configuration backup is available, this action can leave the site without the configuration needed to resume normal operation, requiring a time-consuming restoration from backup or, in the worst case, a full re- commissioning process involving significant manual effort. Given this risk, a factory reset is generally considered a last-resort troubleshooting action, used only when less drastic remote troubleshooting steps have been exhausted, and only after confirming that a usable backup exists and that the operational impact (likely requiring an extended outage for the affected cells) is acceptable and properly scheduled. The action does not automatically create its own backup, nor is its impact limited to cosmetic indicators - it directly affects the unit's operational state.
NEW QUESTION # 15
Why does NetAct support configuring automatic notifications, such as email or SMS, for Critical severity alarms to NOC personnel?
Answer: C
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.
