The H13-711_V3.5 practice questions helped me distinguish technologies such as HDFS, HBase, Hive, Spark, Flink, Kafka, Elasticsearch, and Redis. Instead of testing definitions only, many questions asked me to select the right tool for storage, processing, ingestion, streaming, or search. This made the overall big-data architecture much easier to understand. Thanks, Killtest. I passed my HCIA-Big Data V3.5 exam successfully!
