NEW QUESTION # 81
A cell repeatedly raises and clears 'Cell Unavailable' alarms. Performance data shows PRB utilization dropping to zero during exactly the same periods. Which area should be investigated FIRST as the likely root cause?
Answer: A
Explanation:
When a cell repeatedly raises and clears 'Cell Unavailable' alarms, and PRB utilization simultaneously drops to zero during exactly those same intervals, this pattern strongly indicates the cell is genuinely going out of service intermittently, rather than a display or reporting artifact. The investigation should focus on causes capable of producing repeated, short-duration outages: transport link instability (brief link flaps causing loss of the cell's connectivity), loss of synchronization reference (particularly significant for TDD 5G, where sync loss can force a cell to stop transmitting to avoid interference), or unexpected hardware resets/restarts of the baseband or radio unit, potentially linked to environmental issues such as overheating or power fluctuations.
NetAct UI theme settings, subscriber handset models, and the billing system are entirely unrelated to RAN service availability and would not explain this correlated alarm and KPI pattern. Correlating alarm timing with PM data and environmental/transport alarms is a key NOC diagnostic technique.
NEW QUESTION # 82
Which file transfer protocol does Nokia recommend for securely delivering software packages, license files, and configuration backups to and from AirScale base stations during remote operations?
Answer: C
Explanation:
SFTP (SSH File Transfer Protocol) runs over an encrypted SSH session, protecting both the transferred files and the authentication credentials used to access the base station, making it the recommended method for remote software delivery, license file transfer, and configuration backup/restore operations on AirScale equipment. Plain FTP transmits both data and login credentials in clear text and is considered unsuitable for production network operations due to the security exposure. TFTP provides no authentication mechanism at all and is generally limited to local, trusted bootstrapping or recovery scenarios rather than wide-area remote software delivery. SMTP is an email transport protocol and is unrelated to file transfer with network elements. Using SFTP ensures that base station software lifecycle activities - including remote updates and patch application performed from a centralized Operations Center - occur over a secure, end-to-end encrypted channel.
NEW QUESTION # 83
Which KPI category includes the RRC Connection Setup Success Rate, which reflects a UE's ability to successfully gain initial access to the network?
Answer: B
Explanation:
Accessibility KPIs measure a UE's ability to successfully access network services when requested. RRC (Radio Resource Control) Connection Setup Success Rate is a foundational accessibility metric in 4G/5G, representing the percentage of RRC connection setup attempts - the first step a UE takes to establish a radio connection with the gNB - that complete successfully. A high accessibility value indicates subscribers can reliably initiate sessions when they attempt to. This differs from Retainability, which measures whether already-established connections remain stable until normally released; Mobility, which assesses handover performance as UEs move between cells; and Integrity, which assesses the quality and throughput of an established connection. Because RRC setup is the entry point to accessing the network, its success rate falls within Accessibility, a category NOC engineers monitor closely to detect access-related problems caused by congestion, misconfiguration, or hardware faults preventing initial connections.
NEW QUESTION # 84
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: B
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 # 85
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: C
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.
