Explanation
Option A is correct because FusionInsight HD (Huawei's Hadoop distribution) configures Spark to run on YARN by default, leveraging YARN's ResourceManager and NodeManagers to allocate CPU and memory across the cluster. This is consistent with how most enterprise Hadoop distributions deploy Spark - YARN provides centralized resource scheduling, multi-tenancy, and integration with the broader Hadoop ecosystem (HDFS, security, etc.). Option B is wrong because Spark does support standalone mode and other resource managers (Mesos, Kubernetes), but in FusionInsight HD's default configuration, YARN is the chosen resource manager, not an optional one. Memory tip: Think "FusionInsight = Hadoop ecosystem = YARN" - any Hadoop-based distribution uses YARN as its native resource manager, and Spark integrates into that default rather than running standalone.
