Huawei H13-629_V3.0 : HCIE-Storage V3.0

For Huawei all-flash storage, which of the following statements are true about link compression in HyperReplication?

• A. Inline compression can be performed on data transmitted over links in real time.
• B. Link compression does not affect services running on the hosts and is imperceptible to users.
• C. Link compression compresses all data (regardless of upper-layer service data or other data) that is transmitted over the network.
• D. After receiving data, the secondary end decompresses it and then verifies its correctness.

The survey stage of storage project planning and design includes determining the project scope, collecting design data, understanding customer requirements and the project background, and identifying key stakeholders and business objectives.

• A. FALSE
• B. TRUE

A financial customer has purchased multiple Huawei flash storage devices for service deployment. Which of the following statements is false about service system I/O characteristics in financial scenarios?

• A. Backup and archiving services mainly involve sequential large I/Os. Writes are involved in backup and archiving services, and reads are involved in restoration services.
• B. Document imaging services mainly involve sequential read of large I/Os, a few metadata operations, and 90% GB-level large file write operations.
• C. The OLAP database mainly involves sequential read of large I/Os. The amount of data processed per batch determines hot data areas.
• D. The OLTP database mainly involves random small I/Os and a few sequential write I/Os. There are more reads than writes, and hot data areas are obvious.

An enterprise plans to purchase OceanStor Pacific storage and is not sure whether to use Distributed Parallel Client (DPC) or Network File System (NFS) for host connection. Which of the following statements about the differences between the two is true?

• A. There is no performance bottleneck on the NFS storage side. Performance is limited only by the performance of a single CPU core on compute nodes.
• B. A single DPC can connect to multiple storage nodes. Data I/Os are cached on the mounted storage node and then written to the destination storage node.
• C. DPC can implement I/O-level load balancing, ensuring real-time load balancing of storage services.
• D. NFS supports POSIX and MPI-IO protocols.

DME is a piece of centralized management and O & M software developed by Huawei for storage devices in data centers. Which of the following unstructured data management capabilities are provided by DME?

• A. Analysis
• B. Optimization
• C. Search
• D. Planning
