Implement a Release Management and Continuous Delivery Strategy (10-15%);
Implement Continuous Integration (20-25%).
Design a Security and Compliance Plan (10-15%);
Facilitate Communication and Collaboration (10-15%);

It is important to know all the subtopics and vital details related to these areas so that you will be able to master them. Therefore, let’s look at this information.

Domain 1: This objective includes three main subtopics that are covering the least amount of the whole exam content. Thus, you should know how to design an actionable alerting strategy, a failure prediction strategy, and implement a health check. This means that it is important to know how to identify metrics and recommend them on which to base alerts, analyze combinations of metrics, as well as design the mechanisms of communication to notify the users of degraded systems. A potential candidate has to understand the behavior of a system, know how to analyze it, measure baseline metrics, and know which tools to use to prevent the system from failure. Analyzing system dependencies is also an important task to deal with.

Domain 2: This area proves that you are capable of designing authentication and authorization strategies, sensitive information management strategies, security and compliance, as well as governance enforcement mechanisms. These four subjects include the skills in organizing teams with the use of Azure AD groups, evaluating vault solutions, as well as assessing and reporting risks. Your knowledge also requires the ability to implement container scanning and Azure policies.

Domain 3: This topic covers the generation of DevOps process documentation, automation of communication with team members, and your ability to communicate with the business stakeholders about the deployment and release information. This means that you have to know how to integrate GitHub as repository with Azure Boards and notify the stakeholders about key metrics, alerts, and severity using Teams, Slack, SMS, or Email. One’s skills in documenting artifacts and external dependencies are also important.

Domain 4: This subject includes the students’ ability to develop logging and telemetry, implement them, and integrate monitoring and logging solutions. Thus, you need to know all about the integration of crash analytics such as Crashlytics or App Center Crashes and creation of the feedback loop from platform monitoring tools, including Event Grid, Azure Platform Logs, and Azure Diagnostics VM extensions. Your knowledge base should include your understanding of key metrics, such as Teams/Slack, network, webhooks, disk, SMS and Email, memory, and CPU, as well as your ability to define them, measure, and implement alerts on them.

Domain 5: The main subtopics of this area include the development of a modern source control strategy, implementation of branching strategies for the source code, integration of source control with tools, and configuration of repositories.

Domain 6: This section covers the learners’ skills in implementing an orchestration automation solution, planning a deployment environment strategy, and developing deployment scripts and templates. Load balancer, App Center, ARM, Azure Stack, Terraform, PowerShell DSC, GitHub Actions, IoT, CLI, multiregion, Azure Pipelines, DR, sovereign Cloud, Jenkins, Azure IoT Edge, CircleCI, mobile, and CDN are the technologies that you should know all about.

Domain 7: The last topic has the highest percentage of the exam content, which means that you will face with more questions from this section than others. It covers a wide area of subjects that include the maintenance of a build strategy, its implementation, as well as design of a package management strategy, build automation, and a process for standardizing builds across the organization.

NEW QUESTION # 195
Where should the build and release agents for the investment planning application suite run? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Explanation

Box 1: A source control system
A source control system, also called a version control system, allows developers to collaborate on code and track changes. Source control is an essential tool for multi-developer projects.
Box 2: A hosted service
To build and deploy Xcode apps or Xamarin.iOS projects, you'll need at least one macOS agent. If your pipelines are in Azure Pipelines and a Microsoft-hosted agent meets your needs, you can skip setting up a self-hosted macOS agent.
Scenario: The investment planning applications suite will include one multi-tier web application and two iOS mobile applications. One mobile application will be used by employees; the other will be used by customers.
