NEW QUESTION # 51
A NOC engineer is preparing to remotely change a cell's duplex mode configuration from FDD to TDD. What critical dependency must be verified before this change can be successfully applied?
Answer: C
Explanation:
TDD (Time Division Duplex) operation requires precise time synchronization between cells, because uplink and downlink transmissions share the same frequency but are separated in time according to a coordinated frame structure. If neighboring TDD cells are not tightly synchronized, their uplink and downlink slots can overlap, causing severe cross-interference between cells. Before converting a cell's duplex mode to TDD, it is therefore critical to verify that the site has access to a reliable, accurate timing/synchronization reference - typically GNSS (such as GPS) or a network-based reference distributed via PTP (Precision Time Protocol) - and that the synchronization source is stable and within required accuracy limits. FDD (Frequency Division Duplex), by contrast, uses separate frequencies for uplink and downlink and does not have this same stringent synchronization dependency. SFTP connectivity, PLMN matching, and alarm acknowledgment status, while operationally relevant in general, are not the critical technical dependency specific to a duplex mode change.
NEW QUESTION # 52
When planning the channel bandwidth and subcarrier spacing for a 5G cell, what is the primary operational impact of these parameters?
Answer: B
Explanation:
Channel bandwidth and subcarrier spacing are fundamental radio configuration parameters that together determine how many Physical Resource Blocks (PRBs) are available within a cell's carrier. Since PRBs are the basic units of radio resource that the scheduler allocates to UEs for both downlink and uplink transmissions, the number of available PRBs directly determines the cell's theoretical capacity - that is, how much traffic the cell can serve simultaneously before becoming congested. A wider channel bandwidth provides more PRBs and therefore greater capacity, while subcarrier spacing affects the size of each PRB in the frequency domain and has implications for latency and mobility performance at different frequency ranges. These parameters are foundational to capacity planning and must be configured consistently with the operator's spectrum holdings and regulatory allocations. They have no bearing on PLMN/TAC identifiers, alarm severity configuration, or O and M transport security, which are governed by entirely separate configuration domains.
NEW QUESTION # 53
After successfully completing a significant remote configuration change on a base station and confirming normal operation, what additional lifecycle management step should the NOC team perform?
Answer: D
Explanation:
Once a significant configuration change has been successfully applied and verified - meaning the network element is operating normally with the new configuration in place - it is good practice to take an updated backup reflecting this new state. This becomes the new baseline restore point for any future changes, ensuring that if a subsequent change needs to be rolled back, the rollback target reflects the current, correct configuration rather than an outdated one that no longer matches the network element's intended state.
Restoring the previous backup immediately after a successful change would simply undo the work just completed, which is counterproductive. Deleting backups removes valuable recovery options and is contrary to good change management practice. Disabling the element's connection to NetAct would prevent the NOC from performing any future monitoring, fault management, or configuration activities on that element, which is operationally undesirable and unrelated to good post-change practice.
NEW QUESTION # 54
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 # 55
While remotely piloting an RF unit replacement, the NOC engineer notices the new unit is detected but the cell fails to come into service, with an alarm indicating a CPRI/eCPRI configuration mismatch. What is a likely cause that the NOC and field engineer should jointly investigate?
Answer: B
Explanation:
A CPRI/eCPRI configuration mismatch alarm following a hardware replacement often indicates that the physical connection topology does not align with what the system's configuration expects - commonly because the replacement RF unit was connected to a different physical port on the baseband module than the original unit occupied. Since configuration data often references specific port mappings to associate logical cell configurations with specific physical RF unit connections, a port mismatch can prevent the system from correctly associating the detected hardware with the expected configuration, resulting in the cell failing to come into service despite the link being physically established. The NOC engineer should work with the field engineer to confirm exactly which physical port the new unit is connected to and compare this against the expected port mapping in the configuration, correcting either the physical connection or the configuration as appropriate. Cosmetic details such as cable ties or paint color, and unrelated identifiers like PLMN ID, have no bearing on this type of technical mismatch.
