课程名称：[2025 练习考试] AWS 认证解决方案架构师 SAA-C03 课程概述： AWS 认证解决方案架构师 - 助理（SAA-C03）练习考试旨在为计划参加考试并获取认证的个人提供准备。该练习考试包含325个独特的高质量真实考试风格的问题及详细解释，以验证个人完成以下任务的能力：根据AWS 设计标准架构框架设计解决方案；设计符合当前业务需求及未来预期需求的AWS服务解决方案；设计安全、可靠、高性能且优化成本的架构；回顾现有解决方案并确定改进措施。 示例问题： 某医疗公司必须在静态情况下加密RDS数据，同时管理和轮换自己的密钥。哪种配置以最小的操作工作量满足这一要求？ 选项1 - 加密附加到RDS主机实例的EBS卷 选项2 - 使用客户管理的KMS密钥（CMK）启用RDS加密 选项3 - 在RDS中存储未加密的数据，仅依赖于应用级AES加密 选项4 - 在数据库内部手动使用透明数据加密（TDE） 正确答案 - 选项2 解释1 - RDS是受管理的，无法访问底层EBS卷 解释2 - RDS处理加密，而客户控制CMK、轮换计划和授权 解释3 - 增加了复杂性，并且不会加密自动备份、快照或副本 解释4 - 需要特定引擎的设置；使用内置的RDS + KMS集成更好 综合说明： 当您在Amazon RDS上选择*启用加密*并引用**客户管理的** CMK时，AWS透明地加密整个存储层（数据文件、重做日志、临时空间和自动备份），同时将完整的密钥所有权留给您。您可以定义密钥策略、启用365天的轮换、创建跨账户授权，并在出现安全漏洞时立即撤销访问权限。由于加密/解密在存储引擎中执行，因此无需更改应用程序代码，且在传输中的性能开销是微不足道的。 练习考试包含以下内容领域及比例： 领域1：设计安全架构（占得分内容的30%） 领域2：设计弹性架构（占得分内容的26%） 领域3：设计高性能架构（占得分内容的24%） 领域4：设计成本优化架构（占得分内容的20%）
The AWS Certified Solutions Architect - Associate (SAA-C03) practice exam is intended for individuals who are planning to take the exam and get certified. The Practice exam contains 325 unique high-quality real exam like test questions+detailed explanations and validates a individuals's ability to complete the following tasks:The exam validates a candidate's ability to design solutions based on the AWS Well-Architected Framework. Design solutions that incorporate AWS services to meet current business requirements and future projected needsDesign architectures that are secure, resilient, high-performing, and cost optimized Review existing solutions and determine improvementsSample QuestionA healthcare company must encrypt RDS data at rest but also manage and rotate its own keys. Which configuration meets this requirement with minimal operational effort?Option 1 - Encrypt the EBS volume attached to the RDS host instanceOption 2 - Enable RDS encryption using a customer‑managed KMS key (CMK)Option 3 - Store data unencrypted in RDS and rely on application‑level AES encryption onlyOption 4 - Use Transparent Data Encryption (TDE) manually inside the databaseCorrect Answer - 2Explanation 1 - RDS is managed; you cannot access underlying EBS volumesExplanation 2 - RDS handles the encryption while the customer controls the CMK, rotation schedule, and grantsExplanation 3 - Adds complexity and doesn't encrypt automated backups, snapshots, or replicasExplanation 4 - Requires engine‑specific setup; still better to use built‑in RDS + KMS integrationOverall explanationWhen you choose *Enable encryption* on Amazon RDS and reference a **customer‑managed** CMK, AWS transparently encrypts the entire storage layer-data files, redo logs, temp space, and automatic backups-while leaving full key ownership to you. You define key policies, enable 365‑day rotation, create cross‑account grants, and can revoke access instantly if required by a breach scenario. Because encryption/decryption is performed in the storage engine, no application code changes are necessary and in‑flight performance overhead is negligible.The Practice tests has the following content domains and weightings:Domain 1: Design Secure Architectures (30% of scored content) Domain 2: Design Resilient Architectures (26% of scored content) Domain 3: Design High-Performing Architectures (24% of scored content) Domain 4: Design Cost-Optimized Architectures (20% of scored content)
