课程名称：[2025 练习考试] Azure 管理员助理 (AZ-104) 课程概述： 本课程旨在帮助学员通过微软认证的 Azure 管理员助理 (AZ-104) 考试，并掌握在现实场景中自信管理 Azure 环境所需的技能。课程专为 IT 专业人员、系统管理员和云工程师设计，使他们能够掌握核心的 Azure 管理任务。 在课程中，您将学习如何管理 Azure 身份和治理、实施和保护存储解决方案、部署和配置虚拟机及容器、构建和管理虚拟网络，以及使用 Azure 原生工具监控资源。通过动手实验、真实案例和以考试为重点的课程，您将获得成功成为 Azure 管理员所需的理论知识和实用经验。 课程结束时，您不仅能够充分准备 AZ-104 考试，还能够承担企业范围内管理 Azure 资源的日常责任。 示例问题： 您是组织的 Azure 管理员。一位用户报告说，他们无法访问之前可以正常工作的 Azure 虚拟机 (VM)。您确认 VM 正在运行。您应该首先检查什么？ A. VM 的系统分配的托管身份 B. VM 的启动诊断日志 C. 网络安全组 (NSG) 规则 D. Azure 资源管理器 (ARM) 模板 正确答案：C. 网络安全组 (NSG) 规则 解释：当用户无法访问 VM 但确认 VM 运行中时，最常见的问题之一是网络层级的访问控制。Azure 网络安全组 (NSG) 控制对 Azure 资源的入站和出站流量。如果 NSG 中未允许正确的入站端口（例如，RDP 的 3389 端口或 SSH 的 22 端口），用户将无法连接，即使 VM 正在运行。A 是错误的，因为托管身份用于资源认证，而不是用户访问。B（启动诊断）有助于排查启动问题，而不是连接性。D（ARM 模板）用于部署，而不是运行时配置。
Prepare to pass the Microsoft Certified: Azure Administrator Associate (AZ-104) exam and gain the skills needed to confidently manage Azure environments in real-world scenarios. This comprehensive course is designed for IT professionals, system administrators, and cloud engineers who want to master core Azure administrative tasks.You'll learn how to manage Azure identities and governance, implement and secure storage solutions, deploy and configure virtual machines and containers, build and manage virtual networks, and monitor resources using Azure-native tools. Through hands-on labs, real-world examples, and exam-focused lessons, you'll gain both the theoretical knowledge and practical experience required to succeed as an Azure Administrator.By the end of this course, you'll not only be well-prepared for the AZ-104 exam but also ready to take on the day-to-day responsibilities of managing Azure resources at an enterprise scale.Sample Question:You are an Azure administrator for your organization. A user reports that they are unable to access an Azure virtual machine (VM) that was working previously. You verify that the VM is running. What should you check first?A. The VM's system-assigned managed identityB. The VM's Boot Diagnostics logsC. The Network Security Group (NSG) rulesD. The Azure Resource Manager (ARM) templateCorrect Answer: C. The Network Security Group (NSG) rulesExplanation:When a user cannot access a VM but the VM is confirmed to be running, one of the most common issues is network-level access control. Azure Network Security Groups (NSGs) control inbound and outbound traffic to Azure resources. If the correct inbound port (e.g., port 3389 for RDP or port 22 for SSH) is not allowed in the NSG, the user will be unable to connect even if the VM is running.A is incorrect because a managed identity is used for resource authentication, not user access.B (Boot Diagnostics) helps troubleshoot startup issues, not connectivity.D (ARM template) is used for deployment, not runtime configuration.
