Question 1
During a complex remote piloting activity involving multiple steps and risk of service impact, what additional coordination practice helps ensure accountability and a clear record of what was agreed and performed at each stage?
A. Conducting the activity exclusively through anonymous communication channels with no record of who performed each action
B. Performing all steps simultaneously without any sequencing to save time
C. Avoiding any real-time communication so as not to distract the field engineer
D. Conducting the activity using a shared bridge call or chat channel where each step, confirmation, and result is verbally or textually logged in real time as the activity progresses
Question 2
After a field engineer completes a baseband module replacement and confirms physical installation is complete, which set of remote checks should the NOC engineer perform to verify successful restoration of service?
A. Confirm only that the module's indicator light is the correct color, without checking any system-level status
B. Confirm the cell(s) return to service without critical or major alarms, CPRI/eCPRI links to RF units are up, and relevant KPIs return to expected baseline levels
C. Confirm the field engineer has left the site, without performing any further remote checks
D. Confirm that the cell's PCI has automatically changed to a new value
Question 3
An operator is considering reducing the PM Result Output Period (ROP) for a set of cells from 15 minutes to
1 minute to enable near real-time troubleshooting. What is the most significant operational trade-off of this change?
A. Shorter ROPs significantly increase the volume of measurement data generated and the load on collection and storage systems
B. Shorter ROPs automatically disable all alarm notifications for the affected cells
C. Shorter ROPs prevent NetAct from displaying any historical performance trends
D. Shorter ROPs make KPI formulas invalid and unusable
Question 4
What is the key difference between a cell that has been administratively 'locked' (disabled) and a cell that reports 'Out of Service' due to a fault?
A. There is no real difference; the two terms describe the same situation
B. 'Out of Service' cells are always the result of a software upgrade in progress
C. 'Locked' cells always operate at higher transmit power than normal
D. 'Locked' reflects a deliberate administrative action taken intentionally, while 'Out of Service' due to a fault reflects an unintended operational failure
Question 5
A remote 5G site has redundant transport paths (primary and backup) providing OandM connectivity to NetAct. What is the main operational benefit of this redundancy?
A. It allows continued remote management, alarm reporting, and visibility from the Operations Center if the primary transport path fails
B. It doubles the radio coverage area of the cell
C. It allows two mobile operators to share the same spectrum band
D. It removes the ongoing need for software updates
