質問 # 111
What is the purpose of license management functionality within NetAct as it relates to base station software and features?
正解：A
解説：
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.
質問 # 112
A NOC engineer needs to open an interactive command-line session directly to an AirScale BTS for advanced diagnostics. Which protocol should be used to comply with Nokia's secure remote access guidelines?
正解：A
解説：
SSH (Secure Shell) is the protocol mandated for interactive command-line access to AirScale base stations because it encrypts the entire session, including login credentials, commands, and output, protecting it from interception as it traverses the wide-area transport network between the Operations Center and the remote site. Telnet transmits all data, including usernames and passwords, in plain text and is explicitly disallowed on production network elements due to the severe security risk. HTTP may be used for some web-based management interfaces but is not the standard for direct CLI diagnostic sessions, and plain HTTP itself is also insecure unless using HTTPS. SNMPv1 is an older management protocol used for polling status and traps, lacks strong authentication and encryption, and is not used for interactive shell sessions. Nokia's hardening guidelines for remote operations require encrypted management protocols such as SSH for all direct element access.
質問 # 113
NetAct shows an AirScale gNB as 'Connection Lost' although there has been no reported power outage at the site. What should the NOC engineer check FIRST?
正解：A
解説：
A complete loss of O and M connectivity status in NetAct, without an associated power loss, most commonly indicates a problem in the IP path between the management system and the site - such as a backhaul
/transport link failure, a routing misconfiguration, a firewall rule change, or a fault on the site router or switch. Standard remote troubleshooting methodology follows a layered, 'isolate before escalate' approach:
confirm basic transport and IP reachability first (for example, checking link status, ping/traceroute results to the site's O and M address) before investigating radio-related items. RF unit VSWR, PCI configuration, and antenna tilt are radio-domain parameters that would not cause a total O and M connectivity loss, and checking them first would waste time and delay resolution. Verifying the transport path quickly narrows the fault domain and determines whether the issue can be resolved remotely or requires field dispatch.
質問 # 114
Before a field engineer disconnects and removes an RF unit for replacement, what action should the NOC engineer typically perform first?
正解：A
解説：
Before a field engineer physically disconnects an RF unit, the NOC engineer should administratively lock the affected cell(s). Locking puts the cell into a controlled, planned out-of-service state, which has several benefits: it allows UEs currently served by the cell to be handed over or to reselect to neighboring cells in an orderly manner before the disconnection occurs, and it ensures that when the RF unit is disconnected, the resulting alarms are correctly understood by the NOC and any monitoring systems as part of a planned maintenance activity rather than an unexpected fault requiring separate investigation or triggering unnecessary alerts/escalations. Increasing neighboring cells' power is not a standard or necessary preparatory step and could introduce interference; deleting the configuration would require a full re- commissioning afterward; and changing the PLMN ID would be both ineffective at preventing the brief outage and disruptive to network identification.
質問 # 115
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?
正解：B
解説：
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.
