NEW QUESTION # 40
A NOC engineer is trying to isolate whether a fault originates in the baseband processing unit or in an RF module of an AirScale BTS. What is a useful FIRST diagnostic step?
Answer: B
Explanation:
When isolating a fault between baseband processing units and RF modules, checking the status and alarm details of the interconnecting interface - typically a CPRI or eCPRI link in AirScale architectures - between the System Module and the Radio unit is a logical first step. Alarms or abnormal status on this link can quickly reveal whether the problem lies in the connection itself (such as a fiber/cable fault or configuration mismatch) or within one of the connected components. This follows the principle of checking interfaces and boundaries before assuming a specific component has failed, avoiding unnecessary or premature hardware replacement. Replacing the antenna skips this diagnostic step entirely and risks an unwarranted field action.
Restarting NetAct is a network-wide action inappropriate for a single-site fault. Increasing transmit power to
'test' a suspected hardware issue is not a valid diagnostic method and could create interference.
NEW QUESTION # 41
What is the purpose of license management functionality within NetAct as it relates to base station software and features?
Answer: D
Explanation:
License management within NetAct provides centralized tracking and administration of license keys and entitlements that govern which optional features, capacity thresholds, or performance levels are enabled on individual network elements. Because software capability and commercial licensing are often separated - meaning a base station may have software installed that is technically capable of supporting a feature, but the feature remains inactive until the corresponding license is applied - license management ensures that the correct entitlements are deployed, tracked for expiration or renewal, and can be audited across the network.
This is important for NOC teams when troubleshooting why an expected feature is not functioning, as a missing or expired license is a common cause distinct from a software or configuration fault. License management has no role in tracking physical spare parts inventory, PLMN ID assignment (a configuration management function), or scheduling site maintenance visits, all of which are handled through separate processes.
NEW QUESTION # 42
During a Site Acceptance Test (SAT) for a newly commissioned 5G site, what is the NOC team's typical role?
Answer: B
Explanation:
During a Site Acceptance Test for a newly commissioned site, the NOC team's role centers on remote verification from the centralized operations perspective, complementing the field team's physical inspection and commissioning activities. This typically includes confirming that the new site and its cells are visible, reachable, and manageable through centralized tools such as NetAct (confirming O and M connectivity is correctly established), verifying that all expected cells come into service without configuration errors, checking that no unexpected or unresolved alarms are present that would indicate an incomplete or faulty installation, and reviewing initial performance indicators (such as successful connection attempts and basic KPI reporting) to confirm the site is functioning as intended before it is accepted into normal operation.
Physical inspections of mounting hardware, cabling installation, and commercial/contractual matters fall outside the NOC's remote operational role and are handled by field engineering, construction, and commercial teams respectively.
NEW QUESTION # 43
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: B
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 # 44
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?
Answer: B
Explanation:
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.
