NEW QUESTION # 108
What is the function of the p-Max parameter broadcast by a 5G cell?
Answer: D
Explanation:
The p-Max parameter is broadcast as part of the cell's system information and specifies the maximum transmit power a UE is allowed to use when transmitting on the uplink within that cell. This is a key input to the UE's uplink power control algorithm and serves several purposes: it helps manage uplink interference toward neighboring cells (particularly important in dense deployments or where uplink interference from high-power UEs could degrade performance for users in adjacent cells), and it can also be used to comply with regulatory power limits for a given frequency band or deployment scenario. This parameter governs UE behavior on the uplink and is distinct from configuredMaxTxPower, which governs the gNB's own downlink transmit power. It also has no relationship to the maximum number of connected UEs (a capacity/licensing consideration) or to the cell's configured bandwidth, which are controlled by separate parameters entirely.
NEW QUESTION # 109
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 # 110
The PLMN ID broadcast by a 5G cell is composed of which two elements, and what is its primary function?
Answer: B
Explanation:
The Public Land Mobile Network Identity (PLMN ID) is composed of a Mobile Country Code (MCC), which identifies the country in which the network operates, and a Mobile Network Code (MNC), which identifies the specific mobile network operator within that country. This combination is broadcast by every cell as part of its system information and is used by UEs during network selection and registration to confirm they are camping on a cell belonging to their home operator or an authorized roaming partner. Correct PLMN configuration is fundamental: an incorrect PLMN ID would cause UEs belonging to that operator to treat the cell as unsuitable, preventing any subscribers from camping on it. This is entirely separate from Cell ID/TAC (used for tracking and identification within a network), PCI (used for physical-layer cell identification), and transport-layer addressing such as IP/VLAN configuration, which serve different operational purposes.
NEW QUESTION # 111
A NOC team uses NetAct to download a new software package to a group of base stations during business hours, but schedules the activation of that software for later that night. What is the primary operational benefit of this 'download now, activate later' approach?
Answer: C
Explanation:
Software lifecycle management for base stations typically separates the download (transfer) phase from the activation phase, because each has different operational implications. Downloading a software package involves transferring a potentially large file to the base station's storage, which consumes transport bandwidth and storage I/O but does not itself interrupt the cell's current operation, since the existing software load continues running unaffected. Activation, by contrast, involves switching to the new software load, which typically requires the affected unit to restart and briefly interrupts service. By downloading during business hours - when transport capacity may be more available and the activation step has not yet occurred - and scheduling activation for a low-traffic maintenance window, the NOC minimizes both the duration of any service interruption and its impact on subscribers. This separation does not eliminate the need for backups, nor does activation occur automatically; it is explicitly scheduled or triggered as a distinct step.
NEW QUESTION # 112
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: B
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.
