Distributed Data Processing relies heavily on a robust network backbone. Key challenges include maintaining consistent directory services (identifying where files and databases reside), managing synchronization traffic, handling concurrency control, and ensuring network link redundancy to support high-availability.
Big Data environments require highly scalable distributed architectures to handle the "3 Vs" (Volume, Velocity, Variety). Infrastructure components include distributed file systems (like HDFS or cloud object stores), high-throughput ingestion pipelines (like Kafka), and distributed query processing frameworks (like Spark or MapReduce) that partition execution workloads across clusters of servers.
分布式数据处理高度依赖强大的网络主干。关键挑战包括维持一致的目录服务（识别文件和数据库所在位置）、管理同步流量、处理并发控制以及确保网络链路冗余以支持高可用性。
大数据环境需要高度可扩展的分布式架构来处理“3 个 V”（量 Volume、速度 Velocity、多样性 Variety）。基础设施组件包括分布式文件系统（如 HDFS 或云对象存储）、高吞吐量摄取管道（如 Kafka）以及分布式查询处理框架（如 Spark 或 MapReduce），这些框架在服务器集群中划分执行工作负载。

Steps to complete:
FastEthernet0/1 and FastEthernet0/2. By default, Spanning Tree Protocol (STP) will block one port to prevent loops, limiting bandwidth to 100 Mbps.完成步骤：
FastEthernet0/1 和 FastEthernet0/2。默认情况下，生成树协议 (STP) 将阻塞其中一个接口以防止环路，可用带宽限制在 100 Mbps。Covers: Chapters 1, 2, and 3 (10 Questions) 范围：第 1、2 和 3 章（共 10 题）
