"AZ-204 Exam微软认证是针对微软认证的一项考试，旨在评估考生在开发 Azure 解决方案方面的技能和知识。此考试可能涵盖了一系列主题，包括使用 Azure 资源管理器模板进行部署、管理 Azure 虚拟机以及处理与 Azure 虚拟机相关的各种操作。" 在 AZ-204 考试中，考生需要对 Azure 平台有深入的理解，特别是在以下几个关键领域： 1. **Azure 资源管理器模板**：资源管理器模板是一种声明式的方法，用于定义 Azure 中的基础设施。通过 JSON 文件，你可以定义要部署的资源、它们之间的依赖关系，以及它们的配置参数。在描述中的问题中，提到使用一个基于现有虚拟机的模板来部署多个虚拟机，这涉及到对模板的适应性修改，以满足特定需求，例如引用管理员密码。 2. **Azure 虚拟机管理**：在问题 #1 中，你需要将一个由 Azure 资源管理器模板部署的虚拟机 (VM1) 从 Host1 移动到 Host2。正确的做法是使用“重新部署”功能。重新部署会将 VM 移到 Azure 基础架构内的新节点，但保留所有配置选项和关联资源。这不同于简单的移动或停止/启动，因为它涉及到 VM 在 Azure 数据中心内部的物理位置的变更。 3. **虚拟机操作**：重新部署 VM 是一项重要的操作，尤其在解决硬件故障或优化性能时。当重新部署 VM 时，它会自动恢复到新的硬件上，保持所有设置和连接的存储不变，确保业务连续性。 4. **安全性和身份管理**：在问题 #2 中，提到了适应模板以引用管理员密码。这涉及到 Azure 身份和访问管理，如 Azure Active Directory (Azure AD) 和安全管理，确保只有授权用户能访问和管理资源。在部署模板时，通常会用参数化的方式来安全地处理敏感信息，如密码，以避免明文暴露。 5. **灾难恢复和高可用性**：虽然没有直接提及，但 Azure 考试通常也会考察如何确保资源的高可用性和灾难恢复计划。这可能包括使用 Azure 可用性集、区域冗余存储和 Azure Site Recovery 服务等。为了准备 AZ-204 考试，考生应熟悉 Azure 的核心服务，包括但不限于虚拟机、存储、网络、身份管理和监控。同时，深入理解 Azure 资源管理器的工作原理，以及如何编写和修改 ARM 模板，是至关重要的。此外，实践操作和模拟测试也是提高准备效果的有效方法。考生可以利用官方文档、在线课程、练习测试和社区资源来提升自己的技能。

Question #20

You develop a Web App on a tier D1 app service plan.

You notice that page load times increase during periods of peak trac.

You want to implement automatic scaling when CPU load is above 80 percent. Your solution must minimize costs.

What should you do rst?

A. Enable autoscaling on the Web App.

B. Switch to the Premium App Service tier plan.

C. Switch to the Standard App Service tier plan.

D. Switch to the Azure App Services consumption plan.

Correct Answer:

Congure the web app to the Standard App Service Tier. The Standard tier supports auto-scaling, and we should minimize the cost. We can then

enable autoscaling on the web app, add a scale rule and add a Scale condition.

Question #21

Your company's Azure subscription includes an Azure Log Analytics workspace.

Your company has a hundred on-premises servers that run either Windows Server 2012 R2 or Windows Server 2016, and is linked to the Azure Log

Analytics workspace. The Azure Log Analytics workspace is set up to gather performance counters associated with security from these linked

servers.

You must congure alerts based on the information gathered by the Azure Log Analytics workspace.

You have to make sure that alert rules allow for dimensions, and that alert creation time should be kept to a minimum. Furthermore, a single alert

notication must be created when the alert is created and when the alert is resolved.

You need to make use of the necessary signal type when creating the alert rules.

Which of the following is the option you should use?

A. The Activity log signal type.

B. The Application Log signal type.

C. The Metric signal type.

D. The Audit Log signal type.

Correct Answer:

Metric alerts in Azure Monitor provide a way to get notied when one of your metrics cross a threshold. Metric alerts work on a range of multi-

dimensional platform metrics, custom metrics, Application Insights standard and custom metrics.

Note: Signals are emitted by the target resource and can be of several types. Metric, Activity log, Application Insights, and Log.

Question #22

You are developing a .NET Core MVC application that allows customers to research independent holiday accommodation providers.

You want to implement Azure Search to allow the application to search the index by using various criteria to locate documents related to

accommodation.

You want the application to allow customers to search the index by using regular expressions.

What should you do?

A. Congure the SearchMode property of the SearchParameters class.

B. Congure the QueryType property of the SearchParameters class.

C. Congure the Facets property of the SearchParameters class.

D. Congure the Filter property of the SearchParameters class.

Correct Answer:

The SearchParameters.QueryType Property gets or sets a value that species the syntax of the search query. The default is 'simple'. Use 'full' if

your query uses the Lucene query syntax.

You can write queries against Azure Search based on the rich Lucene Query Parser syntax for specialized query forms: wildcard, fuzzy search,

proximity search, regular expressions are a few examples.
