NEW QUESTION # 63
Why is it important for the NOC engineer to confirm the affected cell is locked and showing as out-of-service (in a planned state) before instructing the field engineer to disconnect any RF cabling at the antenna?
Answer: C
Explanation:
Confirming that a cell is locked and in a planned out-of-service state before any physical RF disconnection serves two important purposes. From a safety perspective, a locked cell is not actively transmitting in normal traffic-carrying operation, reducing RF exposure risk to the field engineer working near the antenna or cabling. From an operational perspective, performing the disconnection on a cell already in a planned, controlled state ensures that the resulting loss of RF connectivity is correctly interpreted within the context of an ongoing planned maintenance activity, rather than triggering an unplanned fault condition that might generate urgent alarms, automatic notifications, or even unnecessary escalations to other teams who are unaware that work is in progress. Locking a cell does not increase its transmit power (the opposite is true - it stops normal transmission), does not trigger any automated parts dispatch, and has no effect on PLMN ID or network-wide UE registration, which are unrelated to a single cell's administrative state.
NEW QUESTION # 64
When planning a maintenance window for a software activation affecting multiple cells at a site, which factor is most important for the NOC team to consider in order to minimize subscriber impact?
Answer: B
Explanation:
Because software activation typically requires affected cells to restart, briefly interrupting service for any actively connected UEs, the most important factor in selecting a maintenance window is identifying a time period when traffic at the site is at its lowest, based on historical traffic pattern analysis. Sites can have different busy-hour profiles depending on their location and the population they serve - for example, a site near a business district may have low traffic late at night, while a site in a residential entertainment area might have different patterns - so generic assumptions about 'off-peak' hours should ideally be validated against actual historical data for that specific site. Software version numbers, PLMN IDs, and current alarm counts have no inherent relationship to traffic levels and should not be used as proxies for determining the best maintenance window; traffic pattern data is the relevant and reliable input for this planning decision.
NEW QUESTION # 65
What is the key distinction between a full site backup and a partial (configuration-only) backup in the context of base station lifecycle management?
Answer: B
Explanation:
A full site backup typically captures both the currently running software load (or a reference to it) and the complete configuration data for the network element, providing the most comprehensive restore point - useful before major changes such as software upgrades or significant hardware-related maintenance. A partial, or configuration-only, backup captures just the configuration data - the set of parameters defining how the element is provisioned - without necessarily including the software image itself. Configuration-only backups are commonly used before smaller-scope parameter changes, where the software load itself is not expected to change, since they are typically faster to perform and require less storage. Choosing the appropriate backup type depends on the scope of the planned change: a software upgrade warrants a full backup, while a routine parameter adjustment may only require a configuration backup. Neither backup type is restricted to alarm history or performance counters, and both can typically be performed remotely without requiring a field engineer to be present.
NEW QUESTION # 66
After exhausting standard remote troubleshooting steps for a persistent Major alarm that remains unresolved, what is the appropriate NOC action?
Answer: C
Explanation:
When standard remote troubleshooting steps for a persistent Major alarm have been exhausted without resolution, the appropriate NOC action is to follow the organization's defined escalation procedures - this may involve escalating to a higher-tier technical support team, a specialist engineering group, or field operations for a possible site visit, depending on the nature of the fault. Critically, the engineer should document the troubleshooting steps already performed, observations made, and relevant data gathered (alarm history, performance data, configuration checks), so the receiving team can proceed efficiently without repeating completed work. Ignoring the alarm leaves a genuine network issue unaddressed and risks breaching service level agreements. Deleting the alarm from NetAct does not resolve the underlying fault and removes valuable diagnostic history. Locking all cells across the entire network is a drastic, disproportionate action that would itself cause a massive outage and is never an appropriate response to a single persistent alarm.
NEW QUESTION # 67
Which Nokia centralized network management system is primarily used by NOC and technical support personnel to monitor, configure, and manage AirScale 5G base stations remotely from an Operations Center?
Answer: C
Explanation:
NetAct is Nokia's centralized Operations Support System (OSS) and is the primary platform used by NOC and technical support teams to manage AirScale 5G base stations from a centralized Operations Center. It integrates Fault Management (FM), Configuration Management (CM), Performance Management (PM), and Software Management (SWM) modules into a single environment, allowing engineers to monitor alarms, push configuration changes, review KPI dashboards, and manage software lifecycle activities across the entire RAN estate without visiting individual sites. While element-level tools such as BTS Site Manager exist for local diagnostics on a single base station, NetAct is the day-to-day platform for remote, network-wide operations. NetGuard focuses on security analytics, CloudBand on NFV infrastructure orchestration, and Nokia Digital Automation Cloud targets private wireless deployments, so none of these serve as the primary RAN operations management system referenced in remote operations procedures.
