1-★★★★★-核心内容
资料口径：本模块以用户提供的 719 道 CLF-C02 题库与前序 C1/C2 项目资料为基础。
题库的 correct_answer、社区投票与评论用于发现考点和争议，不自动等于当前 AWS 官方结论。
本模块没有在生成过程中擅自用外部常识覆盖题库内容。
凡现有项目已经明确标记为 [UPDATED]、[LEGACY]、[CURRENT-OUT-OF-SCOPE] 的内容，会继续保留这些状态提示。
正式考试前，涉及当前产品状态和 Support 计划等时效信息仍应再对照 AWS 官方页面。
这张表特别适合找“高频干扰项”：服务自己不一定总是答案，但经常被拿来和别的服务比较。
