A. Regulatory-level WORM complies with SEC17a-4.
B. Enterprise-level WORM supports privileged deletion.
C. Regulatory-level WORM supports privileged deletion.
D. Enterprise-level WORM complies with SEC17a-4.

答案：A,B

問題 #24
Which of the following basic elements are contained in an object? (Select all that apply)

A. Customized metadata
B. System metadata
C. Object identifier (OID)
D. Data

答案：A,B,C,D

解題說明：
Unlike traditional file storage which uses a hierarchical tree structure, Huawei Object Storage utilizes a flat structure where each " object " is a self-contained unit of data. According to the documentation, an object consists of four fundamental components:
* Data (Option D): The actual content of the file (e.g., a photo, video, or document).
* System Metadata (Option C): These are fixed attributes managed by the storage system, such as file size, creation date, last modified time, and HTTP content type.
* Customized Metadata (Option B): A unique advantage of object storage is the ability to attach user- defined tags or labels to an object (e.g., " Patient_ID: 12345 " or " Department: Radiology " ). This allows for advanced data indexing and searching without opening the file itself.
* Object Identifier (OID) (Option A): This is the unique key or " Address " used to retrieve the object.
In a flat namespace, the OID ensures that every piece of data can be located instantly without traversing a complex directory path.

問題 #25
Which of the following are expansion scenarios that Huawei scale-out storage is intended for?
(Choose all that apply.)

A. Intelligent video and image storage
B. Big data
C. High performance data analytics (HPDA)
D. Backup and archiving of mass data

答案：A,B,C,D

解題說明：
Huawei scale-out storage is designed for massive capacity, high throughput, and linear scalability, making it suitable for intelligent video/image storage, HPDA workloads, big data platforms, and large-scale backup and archiving scenarios.

問題 #26
Which of the following activities may lead to cyber security issues?

A. Customer account authorization has expired but continue use to solve problem.
B. Ask for a third-party company for service support. To locate faults, the third-party service personnel send customer network data ....
C. The laptop was virus-infected and can't be removed completely at the moment, engineer still holds chance to connect to customer
D. Add a private mailbox address to the alarm notification mailing list of the customer system for testing the alarm email function is....

答案：A,B,C,D

問題 #27
Which statements are correct about NVMe over Fabrics (NVMe-oF) (RoCE v2)? (Select all that apply)

A. Traditional Ethernet can transmit NVMe-oF (RoCE v2) data packets without packet loss.
B. NVMe-oF (RoCE v2) significantly improves performance by using Remote Direct Memory Access (RDMA).
C. The cost of NVMe-oF (RoCE v2) is generally higher than that of NVMe-oF (Fibre Channel).
D. Lossless Ethernet can transmit NVMe-oF (RoCE v2) data packets.

答案：B,D

解題說明：
NVMe over Fabrics (NVMe-oF) using the RoCE v2 (RDMA over Converged Ethernet) protocol is a high- speed communication technology supported by Huawei OceanStor Dorado systems. Option B is correct because RoCE v2 utilizes RDMA, which allows data to be transferred directly from the memory of one computer to another without involving the CPU of either system. This significantly reduces latency and CPU overhead compared to traditional iSCSI.
Option C is correct because RoCE v2 requires a " Lossless Ethernet " environment to function correctly.
Traditional Ethernet (Option A) is a " best-effort " delivery system that allows for packet drops during congestion; however, RDMA protocols are highly sensitive to packet loss. To support RoCE v2, the network must implement Data Center Bridging (DCB) features like Priority Flow Control (PFC) and Enhanced Transmission Selection (ETS) to ensure a zero-packet-loss environment. Regarding cost (Option D), RoCE v2 often leverages existing Ethernet infrastructure, making it generally more cost-effective than deploying a dedicated Fibre Channel (FC) fabric, which requires specialized HBAs and FC switches.
