質問 # 26
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?
正解：A
解説：
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.

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?
正解：D
解説：
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.
質問 # 28
In NetAct's role-based access control model, which role would typically be assigned to a NOC engineer who needs to perform routine cell parameter and neighbor relation changes, but should NOT be able to modify user accounts or system-wide security settings?
正解：D
解説：
NetAct's role-based access control allows different roles to be granted permission sets aligned with job responsibilities. An 'Operator' role with CM provisioning privileges is scoped to perform day-to-day configuration tasks - such as modifying cell parameters, neighbor relations, or power settings - without holding the broader privileges of a System Administrator, who manages user accounts, security policy, and overall NetAct system configuration. A Guest or read-only user can view alarms, performance reports, and configuration data but cannot make changes, so this role would prevent the engineer from performing the required provisioning tasks at all. A Database Administrator role focuses on the underlying database infrastructure supporting NetAct rather than RAN configuration provisioning. Assigning an Operator role with CM privileges follows the least-privilege principle: the engineer receives exactly the access required to perform routine provisioning, and nothing more.
質問 # 29
After successfully completing a significant remote configuration change on a base station and confirming normal operation, what additional lifecycle management step should the NOC team perform?
正解：B
解説：
Once a significant configuration change has been successfully applied and verified - meaning the network element is operating normally with the new configuration in place - it is good practice to take an updated backup reflecting this new state. This becomes the new baseline restore point for any future changes, ensuring that if a subsequent change needs to be rolled back, the rollback target reflects the current, correct configuration rather than an outdated one that no longer matches the network element's intended state.
Restoring the previous backup immediately after a successful change would simply undo the work just completed, which is counterproductive. Deleting backups removes valuable recovery options and is contrary to good change management practice. Disabling the element's connection to NetAct would prevent the NOC from performing any future monitoring, fault management, or configuration activities on that element, which is operationally undesirable and unrelated to good post-change practice.
質問 # 30
How do NetAct and the AirScale BTS local Element Manager (Site Manager) typically relate to each other in day-to-day remote operations?
正解：B
解説：
NetAct provides a consolidated, network-wide view of alarms, performance, configuration, and software status for all managed base stations, enabling efficient centralized operations at scale - this is the day-to-day tool for NOC monitoring and bulk provisioning. The BTS Site Manager (Element Manager) complements NetAct by providing detailed, element-specific access for situations requiring deep local diagnostics, such as reviewing local hardware status, logs, or actions not yet reflected centrally, or when central connectivity to a site is degraded. These two tools work together rather than as substitutes for one another. NetAct supports Nokia's Single RAN concept across 2G, 3G, 4G, and 5G technologies on shared hardware, so describing it as
2G/3G-only is incorrect, and the Element Manager is scoped to a single element rather than managing multiple sites network-wide, which is NetAct's role.
