質問 # 98
Before granting a new NOC engineer remote access credentials to production AirScale sites, what should be verified according to Nokia's operational security practices?
正解：A
解説：
Before a new NOC engineer is granted credentials to access live production AirScale sites, operational security practice requires confirming the individual has completed the appropriate training for the tools, procedures, and risks involved, and that their account is provisioned with a role matching their actual job responsibilities, following the least-privilege principle of granting only the access necessary to perform assigned tasks. This minimizes the risk of accidental or unauthorized actions on a live network by inexperienced or over-privileged users. Owning a personal mobile phone or holding physical site keys relate to unrelated personal or facility-access matters and have no bearing on logical access provisioning for remote OAM systems. Granting unrestricted access to all NetAct modules by default directly contradicts least- privilege principles, increases organizational risk, and is explicitly the kind of practice operational security guidelines aim to prevent.
質問 # 99
What is the key difference between a graceful restart and an immediate (forced) restart of a base station unit during maintenance activities?
正解：A
解説：
A graceful restart is designed to minimize the impact on active subscribers by allowing the system, where possible, to complete in-progress procedures or facilitate handovers of active sessions to neighboring cells before the restart actually takes effect, reducing the number of abruptly dropped connections. An immediate, or forced, restart proceeds without this consideration, restarting the unit right away regardless of any active sessions, which will be dropped as a result. NOC engineers may choose between these options depending on the urgency of the situation: a graceful restart is generally preferred for planned maintenance activities to minimize subscriber impact, while an immediate restart might be necessary in scenarios where a unit is unresponsive or where the urgency of resolving a critical fault outweighs the brief additional impact of dropped sessions. Neither option permanently disables the unit, and graceful restarts can be initiated remotely - they do not require physical power-cycling on site.
質問 # 100
Following completion of a hardware replacement and remote piloting activity, which combination of checks represents the most complete final verification before the NOC engineer closes out the activity as successful?
正解：D
解説：
A complete final verification after a hardware replacement and remote piloting activity should confirm multiple dimensions of the site's restored operational state. This includes checking that alarms directly related to the replaced component and the maintenance activity itself have cleared as expected (with any remaining alarms understood and unrelated to the activity), confirming the affected cell has been unlocked and successfully returned to an in-service state, verifying that relevant communication links - such as CPRI
/eCPRI links to RF units or the AISG bus connection to antenna line devices - report normal status, and reviewing short-term performance indicators to confirm they are consistent with the site's established baseline, indicating the cell is performing as expected under real traffic. Only this combination provides genuine assurance that the activity was successful end-to-end. Administrative details like tool packing, serial number matching against shipping records (while useful for inventory purposes), and weather conditions do not address whether the network element is actually functioning correctly.
質問 # 101
A NOC engineer is preparing to remotely change a cell's duplex mode configuration from FDD to TDD. What critical dependency must be verified before this change can be successfully applied?
正解：B
解説：
TDD (Time Division Duplex) operation requires precise time synchronization between cells, because uplink and downlink transmissions share the same frequency but are separated in time according to a coordinated frame structure. If neighboring TDD cells are not tightly synchronized, their uplink and downlink slots can overlap, causing severe cross-interference between cells. Before converting a cell's duplex mode to TDD, it is therefore critical to verify that the site has access to a reliable, accurate timing/synchronization reference - typically GNSS (such as GPS) or a network-based reference distributed via PTP (Precision Time Protocol) - and that the synchronization source is stable and within required accuracy limits. FDD (Frequency Division Duplex), by contrast, uses separate frequencies for uplink and downlink and does not have this same stringent synchronization dependency. SFTP connectivity, PLMN matching, and alarm acknowledgment status, while operationally relevant in general, are not the critical technical dependency specific to a duplex mode change.
質問 # 102
A NOC team needs to apply an identical parameter change - updating a neighbor relation threshold - across
200 cells in a region. What NetAct CM capability is best suited to perform this efficiently and consistently?
正解：B
解説：
NetAct's Bulk Configuration Management capability, often referred to as Mass Update, is specifically designed for scenarios where the same configuration change needs to be applied consistently across a large number of network elements or cells. Rather than requiring an engineer to manually access each cell individually - which would be slow, error-prone, and difficult to audit - Bulk CM allows the target parameter, new value, and the set of affected cells to be defined once, with the change then propagated and applied consistently across all selected targets, typically with built-in logging and the ability to verify success or failure per element. This significantly reduces the time required for large-scale changes and ensures consistency, which is particularly important for parameters like neighbor relation thresholds where inconsistent configuration across a cluster could create uneven mobility behavior. Software Management's delivery function addresses SW lifecycle, not parameter changes, and Fault Management is unrelated to configuration provisioning.
