NEW QUESTION # 23
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?
Answer: A
Explanation:
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.
NEW QUESTION # 24
How do NetAct and the AirScale BTS local Element Manager (Site Manager) typically relate to each other in day-to-day remote operations?
Answer: D
Explanation:
NetAct provides a consolidated, network-wide view of alarms, performance, configuration, and software status for all managed base stations, enabling efficient centralized operations at scale - this is the day-to-day tool for NOC monitoring and bulk provisioning. The BTS Site Manager (Element Manager) complements NetAct by providing detailed, element-specific access for situations requiring deep local diagnostics, such as reviewing local hardware status, logs, or actions not yet reflected centrally, or when central connectivity to a site is degraded. These two tools work together rather than as substitutes for one another. NetAct supports Nokia's Single RAN concept across 2G, 3G, 4G, and 5G technologies on shared hardware, so describing it as
2G/3G-only is incorrect, and the Element Manager is scoped to a single element rather than managing multiple sites network-wide, which is NetAct's role.
NEW QUESTION # 25
After a field engineer replaces an RF unit, the NOC engineer observes that the eCPRI link between the baseband and the new RF unit remains down, even after the cell is unlocked. What should the NOC engineer do first?
Answer: A
Explanation:
When an eCPRI (or CPRI) link remains down immediately following a physical hardware replacement, the most probable and easily verified cause is a physical-layer issue introduced during the replacement itself - such as a fiber connector not being fully seated, an SFP transceiver not properly inserted, a mismatched or faulty SFP module, or an incorrect port connection. Since the field engineer is already on site with direct physical access, the most efficient first step is to ask them to verify these physical connections before the NOC engineer invests time in deeper remote diagnostics, which would be premature given how common and simple physical connection issues are immediately after hardware work. Ordering a new baseband module is a significant escalation that should only follow ruling out simpler causes; locking the cell and closing the ticket would leave the site non-functional; and PLMN ID has no relationship to eCPRI link establishment, which operates at a lower layer entirely unrelated to network identity broadcasting.
NEW QUESTION # 26
Which NetAct functional area provides tools that allow an operator to apply the same parameter change consistently to multiple AirScale base stations or cells in a single operation?
Answer: B
Explanation:
NetAct's Configuration Management (CM) area provides bulk/mass update capabilities that let an operator define a parameter change once - such as updating a neighbor relation, adjusting a power parameter, or enabling a feature - and apply it consistently across many base stations or cells in a single, auditable operation. This is fundamental to standard provisioning tasks covered in remote operations, allowing large- scale configuration rollouts without logging into each element individually, while maintaining consistency and an audit trail of who changed what and when. Fault Management focuses on collecting, displaying, and correlating alarms rather than making configuration changes. Performance Management focuses on collecting and reporting KPI/counter data. Software Management can distribute and activate software packages across multiple base stations, but it does not handle parameter and configuration provisioning, which is the specific domain of Configuration Management's bulk operations tools.
NEW QUESTION # 27
A transport alarm 'Ethernet link down' is raised on the BTS-side interface toward the aggregation router. What is an appropriate FIRST remote action for the NOC engineer?
Answer: D
Explanation:
When a transport-side alarm such as 'Ethernet link down' is raised on the BTS-facing interface toward the aggregation router, the appropriate first remote action is to investigate the physical and data-link layer status of that interface - checking link/port status, interface configuration such as speed and duplex settings and VLAN membership, and any visible cable/connector status indicators through management tools. If the issue appears to originate on the transport provider's side of the connection (such as a leased line or microwave link fault), coordinating with that provider is the next step. Only if remote checks cannot resolve the issue, or clearly indicate a physical hardware or cabling fault at the site, would on-site dispatch be considered.
Replacing the RF module addresses radio hardware, not a transport link fault, and modifying neighbor relations or cell bandwidth are RAN configuration changes that would not resolve a physical link failure.
