Answer : A, C

Comprehensive and Detailed in Depth

A . FTP servers are typically used for file storage.

This is correct. FTP (File Transfer Protocol) servers are indeed a common way to store and share files. They are widely used for basic file storage and transfer needs.

B . Object storage devices are typically disk arrays.

This is incorrect. Object storage devices are not typically disk arrays in the traditional sense. Object storage is designed for massive amounts of unstructured data. While they use disks for persistence, they present data as objects with metadata, rather than as blocks or files. Object storage solutions often use distributed systems across many servers, not just a single array.

C . Block storage applies to databases that require high I/O.

This is correct. Block storage is ideal for applications that demand high I/O performance, such as databases. Block storage provides raw, unformatted data blocks, giving applications direct control and low latency.

D . Block storage typically applies to remote backup storage.

This is partially true, but not the typical primary use case. While block storage can be used for remote backups, it is generally considered less efficient and more expensive than object storage for this purpose. Object storage is better suited for large, unstructured backup datasets. Block storage is better for applications that need fast read/write speeds, such as databases and virtual machines.

Therefore, the correct answers are A and C.

Reference to Huawei Data Center Network documents:

Huawei storage product documentation detailing block storage (e.g., OceanStor Dorado), file storage, and object storage (e.g., OceanStor Pacific) characteristics and use cases.

Huawei white papers on data center storage architectures, which compare and contrast different storage types.

Huawei HCIP-Storage training materials, which will have very detailed information regarding each of the storage types, and their use cases.

Answer : A, D

In Huawei's M-LAG (Multi-Chassis Link Aggregation), the heartbeat link (or peer-link) ensures communication between member devices. A fault in this link can impact M-LAG operation. Let's evaluate each statement:

A . The fault that two master devices exist cannot be detected in the case of a peer-link fault: This is false. A peer-link fault can be detected, and mechanisms like dual-master detection (e.g., via Inter-Chassis Communication Link or ICC) can identify if both devices assume master roles, triggering corrective actions. FALSE.

B . An alarm is triggered: This is true. A peer-link fault generates an alarm to notify administrators, as it's a critical failure in M-LAG operation, per Huawei's fault management system. TRUE.

C . The fault protection mechanism is triggered: This is true. Huawei M-LAG includes protection mechanisms (e.g., failover to backup links or shutdown of conflicting interfaces) to mitigate peer-link faults and maintain service continuity. TRUE.

D . Services are affected: This is false. With proper configuration (e.g., redundant links or fast failover), services should not be affected by a peer-link fault, as M-LAG is designed for high availability. Impact depends on redundancy, but the design goal is uninterrupted service. FALSE.

Thus, A and D are false statements because dual-master faults can be detected, and services are not necessarily affected with adequate redundancy.

Answer : C

M-LAG (Multi-Chassis Link Aggregation) on Huawei CE series switches enhances high availability and load balancing by making two switches appear as one. Let's evaluate each statement:

A . Multi-level M-LAG is mainly used to construct a large Layer 2 network in a DCN or directly connect DCNs at Layer 2: This is true. Multi-level M-LAG extends the topology across multiple layers or data centers, facilitating large Layer 2 domains, a common use case in Huawei DCNs. TRUE.

B . In multi-level M-LAG networking, you can manually configure the root bridge to prevent STP loops: This is true. Manual configuration of the root bridge (e.g., using STP priority) is supported to optimize path selection and prevent loops, especially in complex M-LAG setups. TRUE.

C . Multi-level M-LAG must be configured based on V-STP: This is false. While V-STP can be used to prevent loops, M-LAG does not require V-STP specifically. Standard STP, RSTP, or MSTP can also be configured, depending on the network design. The requirement is loop prevention, not a mandatory V-STP dependency. FALSE.

D . M-LAG networking can be classified into single-level M-LAG networking and multi-level M-LAG networking: This is true. Single-level M-LAG connects two switches directly to devices, while multi-level M-LAG extends across additional layers or devices, a recognized classification in Huawei documentation. TRUE.

Thus, C is the false statement because multi-level M-LAG does not mandate V-STP configuration.

Answer : B, D

In Huawei's M-LAG (Multi-Chassis Link Aggregation) on CE series switches, the two member devices synchronize critical information over the peer-link to ensure seamless operation and failover. Let's evaluate each option:

A . ACL information: Access Control List (ACL) configurations are typically not synchronized in M-LAG, as they are device-specific security policies. Synchronization of ACLs is not a standard feature in Huawei's M-LAG implementation. NOT SYNCHRONIZED.

B . STP status: Spanning Tree Protocol (STP) status (e.g., port roles, states) is synchronized to maintain a consistent loop-free topology across M-LAG peers, especially when V-STP or other STP variants are used. SYNCHRONIZED.

C . Device name: Device names are administrative identifiers and are not synchronized, as they do not impact traffic forwarding or M-LAG functionality. NOT SYNCHRONIZED.

D . LACP information: Link Aggregation Control Protocol (LACP) status (e.g., link states, aggregation details) is synchronized to ensure both M-LAG devices present a unified LAG to downstream devices, supporting load balancing and failover. SYNCHRONIZED.

Thus, B (STP status) and D (LACP information) are synchronized between M-LAG devices.

Answer : A, C

In Huawei's CloudFabric Solution, the iMaster NCE-Fabric controller manages the network in computing scenarios (e.g., virtualized environments). Controller interconnection with external systems can be mandatory or optional depending on functionality. Let's evaluate each option:

A . Interconnection with FabricInsight: This is optional. FabricInsight is an analytics and assurance tool that enhances visibility and troubleshooting but is not required for basic controller operations in the computing scenario. OPTIONAL.

B . Interconnection with the authentication server: This is mandatory. Authentication servers (e.g., RADIUS, TACACS+) are essential for securing access to the controller and managed devices, a core requirement in computing scenarios. NOT OPTIONAL.

C . Interconnection with eSight: This is optional. eSight is a network management platform that provides additional monitoring and management capabilities, but it is not necessary for core controller functionality. OPTIONAL.

D . Interconnection with the VMM (Virtual Machine Manager): This is mandatory. Interconnection with a VMM (e.g., FusionCompute, OpenStack) is required to manage virtualized computing resources and orchestrate network services in the computing scenario. NOT OPTIONAL.

Thus, A (Interconnection with FabricInsight) and C (Interconnection with eSight) are optional services for controller interconnection.
