NEW QUESTION # 20
In the network virtualization scenario or during secondary orchestration in the cloud-network integration scenario, iMaster NCE-Fabric provides functions such as pre-event verification, simu-lation, and resource consumption estimation for service provisioning. These functions help users determine whether the service orchestration can achieve the expected effect, whether existing services will be affected, and how many device resources will be consumed.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
Huawei iMaster NCE-Fabric provides advanced capabilities for intelligent service orchestration and pre- deployment validation , especially in network virtualization and cloud-network integration scenarios.
The statement is correct because iMaster NCE-Fabric includes pre-event verification and simulation features , which allow administrators to:
Simulate service deployment before actual configuration is applied
Evaluate the impact on existing services to avoid disruptions
Estimate resource consumption , such as TCAM, bandwidth, and device capacity These capabilities are part of Huawei's intent-driven networking (IDN) approach, where the system validates whether the intended service can be safely and effectively deployed.
Additionally, these functions help:
Prevent configuration errors
Reduce service deployment risks
Improve network reliability and predictability
Enable efficient capacity planning
Huawei emphasizes closed-loop automation , where planning, simulation, deployment, and verification are integrated into a single workflow.
Therefore, the statement accurately reflects Huawei CloudFabric capabilities and is TRUE .
NEW QUESTION # 21
NETCONF provides a lock mechanism to prevent conflicts between multiple users ' configurations. SNMP does not provide such a mechanism when multiple users perform operations on the same configuration item.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
In Huawei's intelligent O & M architecture, NETCONF is a modern network management protocol designed for transactional, reliable, and concurrent-safe configuration management . One of its key features is the lock mechanism , which allows a user or system to lock a configuration datastore (such as candidate or running configuration) to prevent other users or processes from making conflicting changes simultaneously. This ensures consistency, atomic operations, and rollback capability , which are critical in automated data center environments like CloudFabric.
On the other hand, SNMP (Simple Network Management Protocol) is primarily designed for monitoring and basic configuration , but it lacks advanced transaction control features. SNMP does not support configuration locking or transactional commits, meaning multiple users can overwrite each other's changes, potentially leading to configuration inconsistencies.
Huawei strongly recommends using NETCONF/YANG-based automation (e.g., via iMaster NCE-Fabric) for modern data center operations because it provides structured data modeling, conflict prevention, and programmability , which SNMP cannot offer.
Therefore, the statement is TRUE .
NEW QUESTION # 22

Answer: A,B,C,D,E
NEW QUESTION # 23
Multichassis Link Aggregation Group (M-LAG) bundles multiple physical links connecting ServerA (a device or host) to DeviceA and DeviceB into a logical link, and allows DeviceA and DeviceB to appear to ServerA as a single device, improving link reliability from card-level to device-level.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
In Huawei data center networking, M-LAG (Multi-Chassis Link Aggregation Group) is a critical technology used to provide active-active access, high availability, and link redundancy . It allows a downstream device (such as a server) to establish a single logical Eth-Trunk across two separate physical switches (DeviceA and DeviceB).
From the server's perspective, both upstream switches appear as one logical device , which eliminates the need for protocols like STP and enables simultaneous forwarding on all active links . This significantly improves bandwidth utilization and avoids blocked links.
The key advantage highlighted in the statement is the improvement of reliability from card-level to device- level . In traditional single-device link aggregation, failures are limited to interface cards. However, with M- LAG, even if an entire switch (device-level failure) goes down, traffic continues to flow through the other active switch without interruption.
Huawei CloudFabric widely adopts M-LAG + VXLAN EVPN to ensure high reliability, fast convergence, and continuous service availability .
Therefore, the statement is TRUE .
