NEW QUESTION # 62
A NOC engineer is considering performing a remote factory reset on a base station as a troubleshooting step for a persistent issue. What is the most significant risk of this action if performed without proper preparation?
Answer: D
Explanation:
A factory reset typically returns a network element to its default, out-of-the-box configuration state, which generally means erasing the unit's current operational configuration - including cell parameters, neighbor relations, and other site-specific provisioning. If performed without first ensuring a verified, complete configuration backup is available, this action can leave the site without the configuration needed to resume normal operation, requiring a time-consuming restoration from backup or, in the worst case, a full re- commissioning process involving significant manual effort. Given this risk, a factory reset is generally considered a last-resort troubleshooting action, used only when less drastic remote troubleshooting steps have been exhausted, and only after confirming that a usable backup exists and that the operational impact (likely requiring an extended outage for the affected cells) is acceptable and properly scheduled. The action does not automatically create its own backup, nor is its impact limited to cosmetic indicators - it directly affects the unit's operational state.
NEW QUESTION # 63
NetAct reports the transport link to a remote 5G site as 'up', but the NOC engineer still cannot establish an OandM session to the AirScale BTS. What is the MOST appropriate next troubleshooting step?
Answer: B
Explanation:
When basic transport/IP connectivity to a site is confirmed as up but an O and M management session still cannot be established, the issue is likely at a higher layer than physical or network-layer reachability.
Common causes include expired or mismatched security certificates, incorrect login credentials, or a misconfigured O and M IP address or management VLAN on the base station itself. A layered troubleshooting approach moves from transport, to network, to application/management-layer checks once lower layers are confirmed functional. Replacing the RF module addresses a hardware radio issue, not an O and M session
/authentication problem, and would be premature without further evidence. Adjusting reference signal power is unrelated to management connectivity. Restarting the entire NetAct server is a drastic action affecting the whole managed network and is never an appropriate first response to a single-site connectivity issue.
NEW QUESTION # 64
How is the Cell Availability KPI typically calculated for a reporting period, and what does this KPI primarily reflect?
Answer: D
Explanation:
Cell Availability is an Availability-category KPI that measures the proportion of a given reporting period during which a cell was operationally able to carry traffic - that is, unlocked, in service, and not blocked by a fault. It is calculated as the ratio of the time the cell was actually available to the total duration of the reporting period, expressed as a percentage. Periods of planned maintenance (administrative locking) are sometimes excluded or tracked separately from unplanned outages, depending on operator reporting policy, since the two have different operational implications. This KPI is critical for service level agreement (SLA) reporting and for identifying cells with recurring stability issues such as repeated automatic resets, hardware faults, or transport outages. It is distinct from throughput-based, handover-based, or alarm-count-based ratios, which belong to other KPI categories and answer different operational questions.
NEW QUESTION # 65
Before applying a significant parameter change to a live production cell, what best practice should a NOC engineer follow regarding the cell's current configuration?
Answer: B
Explanation:
Taking a configuration backup or snapshot of the current parameter settings before applying a significant change is a fundamental change management best practice. If the new configuration causes unexpected behavior - such as degraded KPIs, connectivity issues, or unintended interactions with other parameters - having a known-good baseline allows the engineer to quickly roll back to the previous configuration, minimizing service impact and downtime while the root cause is investigated. While some configuration management tools may offer change history or versioning features, relying solely on this without an explicit pre-change backup is risky, and the assumption that changes are always automatically and fully reversible is incorrect. Deleting the existing configuration before applying a new one is highly disruptive and would cause an outage. Disabling alarm reporting during a change is dangerous, as it would prevent the NOC from detecting genuine problems introduced by the change itself, undermining the very monitoring needed to assess the change's impact.
NEW QUESTION # 66
For security segmentation, NOC personnel typically do not connect directly from their workstations to production AirScale base stations. Instead, they first authenticate to an intermediate, hardened host. What is this intermediate host commonly called?
Answer: A
Explanation:
A jump server (also called a bastion host) is an intermediate, hardened system that NOC personnel must authenticate to before establishing management sessions, such as SSH or NetAct client connections, to production base stations. This design reduces the attack surface of the network because production elements only need to accept management connections originating from a small number of tightly controlled, monitored hosts, rather than from every individual engineer's workstation across potentially varied locations and security postures. Jump servers also provide a natural point for enforcing multi-factor authentication, centralized session logging, and periodic access reviews. An edge router forwards traffic between networks but is not an access-control checkpoint for engineer sessions. A load balancer distributes traffic across multiple servers for performance/availability, and a DNS server resolves hostnames to IP addresses - neither performs the security gatekeeping function described.
