질문 # 83
Following completion of a hardware replacement and remote piloting activity, which combination of checks represents the most complete final verification before the NOC engineer closes out the activity as successful?
정답：C
설명：
A complete final verification after a hardware replacement and remote piloting activity should confirm multiple dimensions of the site's restored operational state. This includes checking that alarms directly related to the replaced component and the maintenance activity itself have cleared as expected (with any remaining alarms understood and unrelated to the activity), confirming the affected cell has been unlocked and successfully returned to an in-service state, verifying that relevant communication links - such as CPRI
/eCPRI links to RF units or the AISG bus connection to antenna line devices - report normal status, and reviewing short-term performance indicators to confirm they are consistent with the site's established baseline, indicating the cell is performing as expected under real traffic. Only this combination provides genuine assurance that the activity was successful end-to-end. Administrative details like tool packing, serial number matching against shipping records (while useful for inventory purposes), and weather conditions do not address whether the network element is actually functioning correctly.
질문 # 84
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?
정답：B
설명：
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.
질문 # 85
During PCI planning for a dense cluster of 5G cells, why is it important to avoid assigning PCI values that result in the same PCI modulo group (such as the same PCI mod 3 value) to closely located neighboring cells?
정답：D
설명：
The Physical Cell Identity has mathematical relationships - such as PCI mod 3 and PCI mod 30 - that determine which specific resource elements certain reference signal sequences are mapped to within the radio frame. When two closely located, mutually visible cells share the same PCI mod 3 group, their reference signals for that group occupy the same time-frequency resources, increasing the likelihood of mutual interference on those reference signals. This can degrade channel estimation and measurement accuracy for UEs near the cell edge between the two cells, indirectly impacting handover performance and link quality.
Careful PCI planning therefore considers not just avoiding direct PCI collisions (identical PCI on neighbors) but also distributing PCI mod group assignments across a cluster to minimize this reference signal overlap.
PCI mod values have no bearing on software versioning, bandwidth limits, or Tracking Area grouping, which are configured through entirely separate parameters.
질문 # 86
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?
정답：B
설명：
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.
질문 # 87
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?
정답：C
설명：
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.
