NEW QUESTION # 95
During a Site Acceptance Test (SAT) for a newly commissioned 5G site, what is the NOC team's typical role?
Answer: A
Explanation:
During a Site Acceptance Test for a newly commissioned site, the NOC team's role centers on remote verification from the centralized operations perspective, complementing the field team's physical inspection and commissioning activities. This typically includes confirming that the new site and its cells are visible, reachable, and manageable through centralized tools such as NetAct (confirming O and M connectivity is correctly established), verifying that all expected cells come into service without configuration errors, checking that no unexpected or unresolved alarms are present that would indicate an incomplete or faulty installation, and reviewing initial performance indicators (such as successful connection attempts and basic KPI reporting) to confirm the site is functioning as intended before it is accepted into normal operation.
Physical inspections of mounting hardware, cabling installation, and commercial/contractual matters fall outside the NOC's remote operational role and are handled by field engineering, construction, and commercial teams respectively.
NEW QUESTION # 96
Which NetAct Fault Management view should a NOC engineer use to see alarms that are currently outstanding and affecting the network, as opposed to alarms that have already been resolved?
Answer: B
Explanation:
The Active Alarms list in NetAct Fault Management displays alarms that are currently outstanding (uncleared) and affecting the network in real time, making it the primary view NOC engineers monitor to identify ongoing issues requiring attention and to prioritize response based on severity. The Alarm History
/Log, in contrast, contains records of past alarms - including those already cleared - which is useful for trend analysis, post-incident reviews, and identifying recurring or intermittent faults over time, but is not the appropriate view for real-time triage of current network health. PM Reports relate to performance counters and KPI trends, not fault/alarm conditions, and the Software Inventory view shows deployed software versions across elements rather than fault information. For day-to-day monitoring and prioritizing immediate response efforts, the Active Alarms list is the correct view.
NEW QUESTION # 97
A NOC engineer needs to recover a base station from a state where its parameter settings have been corrupted, but the underlying software load is functioning correctly. Which type of backup would be most directly applicable to resolving this specific issue?
Answer: D
Explanation:
When the issue is specifically that parameter/configuration data has become corrupted while the underlying software load remains functional, the most directly applicable recovery resource is a configuration backup - which contains the parameter settings (cell configuration, neighbor relations, transport settings, and so on) independent of the software image. Restoring from a configuration backup can address the corrupted settings without the additional time and disruption of reinstalling or reactivating software, which would be unnecessary in this scenario since the software itself is not the problem. Configuration data is a distinct dataset from the software image, not embedded within it, which is precisely why configuration-only backups exist as a lighter-weight option for scenarios like this. Alarm history and PM counter exports are records of operational events and measurements respectively - neither contains the parameter configuration data needed to restore an element's settings, making them unsuitable for this recovery scenario.
NEW QUESTION # 98
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: A
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 # 99
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: B
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.
