The cloud-native database MRS is one of the big data solutions provided by HUAWEI CLOUD for customers. Which of the following descriptions about IRS is wrong?

Question

Options

• AMRS can connect to Kafka in real time, analyze Storm in real time, mass store Hbase and other
• BHadoop's distributed file system HDFS can realize reliable centralized reading and writing of
• CMRS provides users with a unified management platform for enterprise-level big data clusters,
• DYou can quickly migrate offline Hadoop big data platform data to the cloud through cloud data

• A
  15% (4)
• B
  77% (20)
• C
  4% (1)
• D
  4% (1)

Explanation

Option B is wrong because it incorrectly describes HDFS as enabling "centralized" reading and writing. HDFS (Hadoop Distributed File System) is explicitly designed for distributed storage across multiple nodes, not centralized storage - centralized storage would introduce a single point of failure, which is precisely what HDFS was built to avoid.

Options A, C, and D are all accurate descriptions of MRS: MRS does integrate with Kafka, Storm, and HBase for streaming and storage workloads (A); it does provide a unified enterprise-level cluster management platform (C); and it does support offline Hadoop data migration to the cloud via migration services (D). These are legitimate capabilities of the HUAWEI CLOUD MRS offering, making none of them the wrong answer.

Memory tip: The word "centralized" in option B is the red flag. Anytime you see HDFS paired with "centralized," that is wrong - the D in HDFS stands for Distributed, and distributed systems exist specifically to eliminate centralized bottlenecks and single points of failure.
