Explanation:
In Huawei’s data center O&M architecture, video is treated as an important auxiliary capability for security and remote operation. The Video Management function is designed not only to view live camera feeds, but also to integrate video resources into the same O&M workflow as alarms, access control events, and environmental monitoring. In typical deployments, the actual video storage and recording are handled by a third-party video surveillance subsystem (for example, an NVR/VMS platform). Huawei’s video management function can connect to that third-party subsystem so that camera resources can be accessed in a unified interface, allowing operators to perform linkage operations such as “view video on alarm” and routine security inspection without switching platforms. Because historical recordings are stored by the surveillance subsystem, once the integration is established and permissions are correctly configured, operators can retrieve and play back historical video for event tracing, audit, and incident investigation. This supports closed-loop O&M: alarm/event occurs → video verification → root-cause confirmation → maintenance action → evidence retention.

Explanation:
In Huawei NetEco statistical reporting, the query range is constrained by the report data retention policy and how summary data is stored. For hourly statistics, the platform keeps a limited window of high-granularity data to balance storage consumption and performance. The hourly report retention is 120 hours, which equals 5 days. That is why hourly statistics queries are limited to 5 days―beyond that window, hourly granularity is no longer retained in the report database for direct querying. For longer time horizons, NetEco relies on lower-granularity summaries (daily/weekly/monthly/yearly). For monthly statistics, the platform supports long-term trend analysis and KPI tracking, and the maximum historical horizon aligns with the long-term statistics retention boundary used by NetEco reporting, which is up to 5 years. This design ensures fast query response, manageable database growth, and clear separation between short-term operational detail (hourly) and long-term management analysis (monthly/yearly).

Explanation:
In Huawei alarm management, masking rules are used to control how alarms are handled and displayed during specific conditions, such as planned maintenance, commissioning, device replacement, or known temporary abnormalities. When a masking rule is applied, the system can change how an alarm is classified so that O&M staff can distinguish between alarms that require immediate action and alarms that are expected or should be excluded from operational statistics. Two key statuses that masking rules can assign are Maintenance and Invalid. Maintenance indicates the alarm is generated during an approved maintenance activity (for example, power-off tests, sensor rewiring, cooling maintenance), so it is treated as expected and does not trigger normal escalation logic. Invalid indicates the alarm is not considered effective for operational follow-up― commonly used when a point is confirmed to be non-applicable, temporarily disabled, or its triggering condition is not meaningful to current operations. By contrast, Valid and Standard represent normal alarm handling states rather than outcomes specifically “identified by masking rules.”

Explanation:
NetEco is a management platform that stores critical operational data, including site configuration, device models, user/role information, historical alarms, trend data, reports, and northbound integration settings. To protect these assets and ensure service continuity, NetEco provides a built-in backup mechanism that supports both manual and automatic backup modes. Manual backup is typically used before major operations such as version upgrades, configuration changes, northbound interface adjustments, or large-scale device onboarding, so engineers can create a restore point on demand. Automatic backup is used for routine risk control and is normally implemented through scheduled tasks, allowing backups to be generated at defined intervals to reduce data-loss exposure in case of hardware failure, system corruption, or accidental misconfiguration. In standard O&M practice, automatic backups are combined with retention policies (for example, keeping a rolling set of backup files), storage capacity checks, and periodic restore verification to confirm backup integrity. This dual-mode backup capability is a foundational requirement for stable long-term operation of management systems like NetEco.

Explanation:
In Huawei NetEco access design, the Web client is reached using HTTPS to protect credentials and management data in transit. During initial deployment and commissioning, engineers access the NetEco login page by entering the server IP address followed by the default HTTPS service port.
Huawei’s standard login method specifies that users open a browser and enter https://NetEco server IP:31943 to access the NetEco login interface. This port is therefore treated as the default Web login port in typical on-premises NetEco deployments, and it is the baseline value referenced in installation and login guidance. Other ports may appear in specific tools, customized scenarios, version variants, reverse-proxy deployments, or when security policy requires port changes, but those are exceptions driven by planning or product packaging. For exam and commissioning purposes, the correct default login port is the one used by the NetEco Web client entry point under the standard deployment model: 31943.

Explanation:
In Huawei delivery scenarios, a preinstalled server means the target software (for example, the NetEco platform and its required runtime components) has already been deployed and integrated on the server image before it is handed over for on-site commissioning. Because the installation media has already been applied, the on-site engineer’s work typically shifts from “software installation” to “environment verification and initialization,” such as confirming OS/service status, checking resource allocation, validating database and middleware health, verifying network planning (IP, gateway, DNS/NTP as required), and completing application-level initialization (site creation, user/role configuration, northbound interface settings, and device/model import if needed). In this case, downloading the full installation package is not a mandatory step for commissioning, because the package is mainly required when performing a fresh installation or reinstall/upgrade. However, standard practice is still to prepare supporting materials (patches, licenses, and compatibility documents) and ensure the preinstalled version matches the project baseline before acceptance.
정답:
Explanation:
NetEco is an enterprise management application with specific runtime dependencies, including supported operating system versions, database/middleware compatibility, CPU/memory/storage requirements, and network/security prerequisites. Because of these dependencies, Huawei does not treat NetEco as “hypervisor-agnostic for any virtualization platform.” In practice, NetEco deployment in virtualized environments is supported only when the virtualization stack meets Huawei’s compatibility requirements, such as validated hypervisors/virtualization solutions, proper virtual hardware settings, and resource reservation rules to ensure stable performance (especially for alarm processing, historical data storage, and northbound integration tasks). If deployed on an unverified virtualization platform, issues may occur such as clock drift, I/O latency, database performance bottlenecks, unstable NIC behavior, or unsupported VM device models, which can impact data collection, event correlation, and overall system stability. Therefore, the correct interpretation is that NetEco can be deployed on supported/verified virtualization platforms, not on any virtualization platform.

Explanation:
Power Partner is Huawei Digital Power’s partner service platform used to support delivery, commissioning, maintenance, and service operations across the full lifecycle of a project. To match real project workflows, the platform defines multiple user roles that align with different responsibilities and permission scopes. A Startup engineer focuses on commissioning activities such as obtaining startup authorization, performing initial configuration, and completing functional verification. A Service engineer handles routine maintenance, inspections, troubleshooting, part replacement guidance, and closure of service cases. A Project manager coordinates delivery milestones, resource planning, and overall service execution to ensure acceptance criteria are met. An Inventory operations manager manages materials/parts flow, tracking, and availability to support timely repair and maintenance. The DOC (Delivery/Dispatch Operations Center) role supports centralized operations such as work order dispatching, progress supervision, and process compliance. A service manager of a representative office typically oversees regional service quality, governance, and authorization control, ensuring the right people have the right access and that services are delivered according to Huawei process requirements.

Explanation:
In Huawei smart module management (such as on the ECC800-Pro/WebUI), Device Management is used to centrally view and maintain managed objects (UPS, SmartLi, rPDU, sensors, air conditioners, etc.). The Overview page provides a consolidated snapshot of a device’s operating status, key parameters, running mode, and basic identification information so engineers can quickly judge whether the device is healthy and online. The Alarm view lists active and historical alarms related to the device, supporting rapid fault isolation and verification after recovery. The Signal view shows monitoring points and I/O status (including analog values and digital inputs/outputs where applicable), which helps engineers confirm sensor wiring, linkage logic, and real-time state changes during commissioning and troubleshooting. The Service period information is used for lifecycle and maintenance planning, such as tracking service time, maintenance intervals, or component life indicators where supported, enabling preventive maintenance and reducing unexpected downtime. Therefore, Device Management supports viewing all four categories.

Explanation:
In Huawei’s data center facility management architecture, the northbound interface of NetEco is designed specifically to integrate with upper-layer systems such as enterprise NMS platforms, SOC/monitoring centers, and customer unified O&M systems. To meet common industry integration practices, NetEco northbound capabilities are not limited to only one interface type. In addition to WebService-style interfaces used for richer data exchange and structured integration, NetEco also supports SNMP-based northbound integration, which is widely used for alarm forwarding, basic status monitoring, and interoperability with standard network management tools. SNMP is particularly common in mixed-vendor environments because it enables a lightweight and standardized method to deliver key alarms and events to a customer’s central monitoring platform without requiring deep application coupling. Therefore, the statement that “only WebService interfaces are supported and SNMP is not supported” is incorrect: NetEco northbound integration supports SNMP along with other northbound interface methods depending on the integration scenario and customer requirements.
정답:
Explanation:
In Huawei data center facility management, NetEco is the management software platform (server/application) used to centrally monitor and manage sites, while iBMC is the out-of-band hardware management interface used for server remote maintenance (such as power control, hardware health, BIOS settings, and remote console) on the specific server where iBMC exists. The iBMC port is not a service access interface for NetEco. NetEco’s backend services are accessed through the server operating system network interfaces (management/service network) and corresponding application ports after the server is properly networked and configured. Even if NetEco is deployed on a Huawei server that has iBMC, iBMC only provides a channel to manage the server hardware and does not expose NetEco application access as an official commissioning/O&M path. Therefore, NetEco backend access should be planned via the site’s management network (IP addressing, routing, security policy), not via iBMC.

Explanation:
Huawei’s ECC800-Pro supports PUE (Power Usage Effectiveness) management as part of its energy efficiency and green data center features. In practical O&M, different sites calculate PUE differently depending on metering topology, what loads are included (IT load only vs. auxiliary loads), and whether the site uses integrated modules (UPS, cooling, lighting, etc.) or external systems. To handle these real-world differences, the ECC800-Pro provides two PUE configuration approaches on the WebUI. “Standard” mode is used when the site’s metering points and calculation logic align with a predefined Huawei template, enabling rapid commissioning and consistent reporting. “User-
defined” mode is used when the customer’s metering structure or management requirements differ―allowing engineers to select specific measurement points, define inclusion/exclusion rules, and tailor the calculation path so that displayed PUE matches the site’s accepted KPI definition. This dual-mode design ensures PUE is both standardized where possible and flexible where necessary, improving energy analysis accuracy and supporting optimization actions.

Explanation:
Huawei data center facility design typically follows a layered fire protection concept: early detection, controlled alarm linkage, and suppression methods that protect equipment and ensure personnel safety. A smoke detection system (often combined with staged alarms) provides early warning so operators can verify events and initiate emergency procedures. For the IT white space, a clean-agent gas extinguishing system is preferred because it suppresses fire without leaving residue and significantly reduces the risk of corrosion or contamination compared with powder-based agents. The extinguishing system is normally integrated with linkage/interlock controls: audible/visual pre-discharge alarms, time delay, emergency abort, door access control logic, and HVAC shutdown or damper control to help maintain agent concentration. This coordinated mechanism reduces false discharge risk while preserving a reliable automatic response if a real fire develops. In contrast, relying only on manual extinguishers is too slow for rapid fire growth, and water sprinklers alone can cause substantial collateral damage to servers and power equipment.

Explanation:
In Huawei smart module commissioning, the ECC800-Pro controller provides a dedicated management access path through its WAN ports. For on-site startup commissioning, technicians typically connect a laptop directly to WAN1 and place the laptop IP address in the same subnet as the controller so they can open the WebUI and complete initial settings (time, network, device discovery, alarm checks, linkage tests, and parameter commissioning). The factory default IP address for WAN1 is 192.168.8.10, which is used as the initial access point before the address is planned and changed to match the customer’s management network. This default design supports quick “point-to-point” commissioning without depending on upstream switches, DHCP services, or enterprise IP planning at the very beginning of deployment. After login, Huawei commissioning practice is to harden access (password/authentication completion), then update network parameters and integrate the ECC800-Pro into the site monitoring network to enable continuous O&M, remote alarm reporting, and device management.

Explanation:
In the FusionDC1000A IT scenario, the power chain is built around an AC input, conditioned backup power, energy storage, and final distribution to the IT racks. Integrated UPS is the core power-conditioning component, providing voltage and frequency stabilization and uninterrupted supply during mains disturbances. The UPS works together with SmartLi, Huawei’s lithium battery system, which serves as the energy storage unit to sustain the load during outages and to support controlled
shutdown or generator switchover. After UPS output, power is delivered to the IT loads through the Power PDB, which performs downstream distribution, branch protection, and organized cable termination toward rack PDUs or IT equipment feeders. By contrast, an AC/DC power system is typically associated with DC bus supply used in telecom-oriented or dedicated DC load scenarios, not the standard IT scenario architecture of FusionDC1000A that is centered on UPS plus battery plus AC distribution. Therefore, the correct components for IT scenarios are SmartLi, Power PDB, and Integrated UPS.
