NEW QUESTION # 93
After a field engineer replaces a Tower Mounted Amplifier (TMA), what remote check should the NOC engineer perform to confirm the new TMA is correctly configured and operating within expected parameters?
Answer: C
Explanation:
A Tower Mounted Amplifier (TMA) is an Antenna Line Device that, like a RET unit, communicates over the AISG bus and has configurable operational parameters - notably its gain settings (which affect uplink signal amplification) and bias/power settings. After a TMA replacement, the appropriate remote verification is to confirm the new unit is detected on the AISG bus (confirming physical and communication-layer connectivity) and that its gain and bias settings can be read and correspond to the values expected for that antenna line's configuration, ensuring the device is operating within the parameters the radio link design assumes. Incorrect TMA gain settings can affect uplink sensitivity and noise figure, impacting uplink performance KPIs. Physical attributes such as housing color or weight have no bearing on functional verification, and TMA replacement has no relationship to the cell's PLMN ID, which is a network identity parameter entirely independent of antenna line equipment.
NEW QUESTION # 94
For security segmentation, NOC personnel typically do not connect directly from their workstations to production AirScale base stations. Instead, they first authenticate to an intermediate, hardened host. What is this intermediate host commonly called?
Answer: A
NEW QUESTION # 95
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: D
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 # 96
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: A
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.
NEW QUESTION # 97
In NetAct Performance Management, what is a 'measurement job'?
Answer: C
Explanation:
In NetAct Performance Management, a 'measurement job' is a configured task that specifies which performance counters or KPIs should be collected, from which network elements (such as specific base stations or cells), and at what collection interval - for example, every 15 minutes or hourly. These jobs are the mechanism by which raw counter data is gathered from the RAN and made available for KPI calculation, reporting dashboards, and threshold-based alerting. Without properly configured measurement jobs covering the relevant counters and elements, the performance data needed to assess network health and detect KPI degradation would simply not be collected. This is distinct from a field technician's scheduled maintenance task, a software upgrade package (a Software Management concept), or a user account (an access control concept) - a measurement job specifically governs the automated, ongoing collection of performance statistics within the PM functional area.
