V-STP (Virtual Spanning Tree Protocol) is a Huawei-specific enhancement of the Spanning Tree Protocol (STP) designed to prevent Layer 2 loops in complex network topologies, including Multi-Chassis Link Aggregation (M-LAG) deployments on Huawei CloudEngine (CE) series switches.

M-LAG Overview: M-LAG allows two switches to appear as a single logical device, connecting to downstream devices via Link Aggregation Groups (LAGs). Without proper loop prevention, incorrect configurations (e.g., misconfigured ports) or physical connections (e.g., redundant links) can cause broadcast storms.

V-STP Role: V-STP extends STP to handle virtualized environments and M-LAG scenarios. It ensures that only one path is active in a loop-prone topology by blocking redundant links, preventing loops caused by misconfigurations or unintended connections. In M-LAG, V-STP coordinates with the peer-link to maintain a loop-free topology.

The statement is TRUE (A) because V-STP is designed to prevent loops in M-LAG deployments due to incorrect configurations or connections. References: Huawei CloudEngine Series Switch Configuration Guide – V-STP and M-LAG; HCIP-Data Center Network Training – Loop Prevention.

Comprehensive and Detailed in Depth Explanation:

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.

In Huawei’s CloudFabric Solution, the iMaster NCE-Fabric SDN controller cluster separates network planes based on carried services to ensure scalability and security. Let’s evaluate each option:

A. BGP microservice plane: This is not a standard plane in Huawei’s SDN architecture. BGP is used in the underlay/overlay but not defined as a separate microservice plane for the controller. FALSE.

B. Southbound service plane: This is true. The southbound plane carries configuration and control data to network devices (e.g., via NETCONF, BGP-EVPN), a critical service plane in SDN. TRUE.

C. Northbound management plane: This is true. The northbound plane provides APIs for management applications and orchestration (e.g., OpenStack integration), handling service requests. TRUE.

D. Internal communication plane: This is true. This plane facilitates communication between controller cluster nodes for synchronization and high availability. TRUE.

Thus, B (Southbound service plane), C (Northbound management plane), and D (Internal communication plane) are the network planes divided based on carried services. References: Huawei CloudFabric Data Center Network Solution – SDN Architecture; HCIP-Data Center Network Training – Controller Planes.
