NEW QUESTION # 28
What is the key difference between a graceful restart and an immediate (forced) restart of a base station unit during maintenance activities?
Answer: A
Explanation:
A graceful restart is designed to minimize the impact on active subscribers by allowing the system, where possible, to complete in-progress procedures or facilitate handovers of active sessions to neighboring cells before the restart actually takes effect, reducing the number of abruptly dropped connections. An immediate, or forced, restart proceeds without this consideration, restarting the unit right away regardless of any active sessions, which will be dropped as a result. NOC engineers may choose between these options depending on the urgency of the situation: a graceful restart is generally preferred for planned maintenance activities to minimize subscriber impact, while an immediate restart might be necessary in scenarios where a unit is unresponsive or where the urgency of resolving a critical fault outweighs the brief additional impact of dropped sessions. Neither option permanently disables the unit, and graceful restarts can be initiated remotely - they do not require physical power-cycling on site.
NEW QUESTION # 29
Which alarm severity level generally requires the MOST urgent NOC response under standard SLA-based prioritization?
Answer: A
Explanation:
In the standard alarm severity model used across telecom Fault Management systems, including NetAct, Critical alarms represent the highest severity, typically indicating a total or near-total loss of service, capability, or capacity with immediate and significant impact on subscribers - for example, a complete cell or site outage. Because of this severe impact, Critical alarms require the most urgent NOC response and are governed by the tightest response and resolution timeframes among all severity levels in most operational SLAs. Major alarms indicate serious degradation requiring prompt, though slightly less immediate, action.
Minor alarms represent non-service-affecting issues that should be addressed to prevent escalation, and Warning alarms are typically informational or preventive, requiring the least urgency. Correctly prioritizing Critical alarms above all others ensures NOC resources focus first on the issues with the greatest impact on network availability and customer experience.
NEW QUESTION # 30
A NOC engineer notices that a cell's PRB (Physical Resource Block) utilization is consistently above 90% during peak hours. What does this MOST LIKELY indicate?
Answer: A
Explanation:
PRB (Physical Resource Block) utilization represents the proportion of a cell's available radio resources that are actively being used to carry traffic at a given time. Consistently high PRB utilization (for example, above
90%) during peak hours indicates the cell is approaching, or already experiencing, capacity congestion - there is little to no spare radio capacity to allocate to new or existing users during busy periods. This can directly affect throughput-related (Integrity) KPIs, since users may receive fewer resources than under lighter load, and can also impact accessibility if the cell becomes unable to admit new connections. This condition does not indicate a hardware failure - the cell is clearly operating and carrying significant traffic - is unrelated to PCI configuration, which is an identification parameter rather than a capacity indicator, and has no relationship to NetAct database storage. High PRB utilization is a capacity signal that may prompt load balancing, optimization, or capacity expansion actions.
NEW QUESTION # 31
After a remote piloting session for a hardware replacement is successfully completed and the site is confirmed to be back in normal operation, what should the NOC engineer do regarding the activity record?
Answer: A
Explanation:
After successfully completing a remote piloting session, documenting the activity in the appropriate maintenance ticket or change record is an essential closing step. This documentation should capture what actions were taken (both remotely and physically), the verification steps performed and their results (such as confirmation that the cell returned to service without alarms and that links were re-established), and the final status of the site. This record provides traceability for future reference - for example, if related issues arise later, or for audit and reporting purposes - and ensures continuity for other team members who may not have been involved in the original activity but need context later. Relying solely on verbal confirmation provides no lasting record and is inconsistent with good operational practice. Deleting the ticket immediately discards this valuable history, and sharing a field engineer's personal contact information with the broader team is unrelated to activity documentation and would raise privacy considerations.
NEW QUESTION # 32
A NOC engineer observes that a 5G cell's average downlink user throughput has dropped significantly, but the cell's PRB utilization remains low and no transport alarms are active. Which root cause is most consistent with these observations?
Answer: A
Explanation:
When PRB utilization is low, the cell is not resource-constrained, which rules out congestion as the cause of reduced throughput. A complete transport failure or an administrative lock would prevent the cell from carrying any traffic at all, which contradicts the scenario where the cell is still active and reporting measurements. The most consistent explanation is degraded radio conditions - for example, increased interference, reduced signal-to-noise ratio (SINR), or coverage issues - which force the scheduler to select lower-order Modulation and Coding Scheme (MCS) values for connected users. Lower MCS values mean each allocated resource block carries fewer bits, directly reducing achievable throughput even though plenty of PRB capacity remains available. Investigating MCS distribution counters and SINR-related measurements alongside checking for nearby interference sources or antenna/feeder issues would be the appropriate next troubleshooting step.
