Question 1

In NetAct's role-based access control model, which role would typically be assigned to a NOC engineer who needs to perform routine cell parameter and neighbor relation changes, but should NOT be able to modify user accounts or system-wide security settings?

A. Operator with Configuration Management (CM) provisioning privileges

B. Database Administrator

C. System Administrator

D. Guest / read-only user

Question 2

A NOC engineer notices that UEs in a cell are triggering handovers to a neighboring cell and then quickly handing back, repeating this cycle (a 'ping-pong' pattern). Which parameter adjustment is most likely to help reduce this behavior?

A. Reducing the channel bandwidth of both cells

B. Increasing the handover event hysteresis and/or time-to-trigger values for the relevant measurement event between the two cells

C. Disabling the neighbor relation between the two cells entirely

D. Increasing the PCI value of one of the two cells

Correct Answer: B

Question 3

Which statement correctly distinguishes 'Integrity' KPIs from 'Accessibility' KPIs in RAN performance management?

A. Integrity KPIs measure the quality/throughput of an already-established connection, while Accessibility KPIs measure the success of initially establishing the connection

B. Integrity KPIs apply only to 2G networks and have no 5G equivalent

C. Accessibility KPIs exclusively measure data throughput

D. They represent the same underlying category, simply measured using different counters

Question 4

A NOC team needs to apply an identical parameter change - updating a neighbor relation threshold - across
200 cells in a region. What NetAct CM capability is best suited to perform this efficiently and consistently?

A. The Fault Management active alarms list

B. Manually logging into each cell's local Element Manager one at a time

C. Software Management's remote delivery function

D. Bulk Configuration Management (Mass Update), which allows the same parameter change to be applied across multiple selected network elements in a single operation

Question 5

When configuring NR-NR (5G-to-5G) neighbor relations to support mobility between two 5G cells operating on different frequency bands, which type of neighbor relation must be established?

A. An inter-frequency neighbor relation, including the appropriate frequency and measurement configuration for the target band

B. An EN-DC relation, since any handover involving different frequencies requires LTE anchoring

C. An intra-frequency neighbor relation only

D. No neighbor relation is required since inter-band handovers occur automatically without configuration

Question 6

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?

A. Historical traffic patterns for the site, choosing a time period when traffic is at its lowest to minimize the number of active sessions affected by the restart

B. The current software version number, since higher version numbers always indicate lower traffic

C. The number of active alarms at the site, since more alarms always mean lower traffic

D. The PLMN ID of the site, since different PLMN IDs require different maintenance windows

Question 7

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?

A. The replacement RF unit is connected to a different physical port than the original unit, resulting in a mapping that does not match the existing configuration

B. The replacement RF unit's exterior paint color does not match the original

C. The field engineer used a different brand of cable ties than specified

D. The cell's PLMN ID was automatically changed during the replacement
