                                              NEW QUESTION # 448
                                              You have a project in Azure DevOps named Project1 that contains two Azure DevOps pipelines named Pipeline1 and Pipeline2.
                                              You need to ensure that Pipeline1 can deploy code successfully to an Azure web app named webapp1. The solution must ensure that Pipeline2 does not have permission to webapp1.
                                              Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

                                              NEW QUESTION # 449
                                              Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
                                              After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
                                              You manage a project in Azure DevOps.
                                              You need to prevent the configuration of the project from changing over time.
                                              Solution: Implement Continuous Assurance for the project.
                                              Does this meet the goal?

                                              Answer: B

                                              Explanation:
                                              Explanation
                                              The basic idea behind Continuous Assurance (CA) is to setup the ability to check for "drift" from what is considered a secure snapshot of a system. Support for Continuous Assurance lets us treat security truly as a
                                              'state' as opposed to a 'point in time' achievement. This is particularly important in today's context when
                                              'continuous change' has become a norm.
                                              There can be two types of drift:
                                              * Drift involving 'baseline' configuration: This involves settings that have a fixed number of possible states (often pre-defined/statically determined ones). For instance, a SQL DB can have TDE encryption turned ON or OFF...or a Storage Account may have auditing turned ON however the log retention period may be less than 365 days.
                                              * Drift involving 'stateful' configuration: There are settings which cannot be constrained within a finite set of well-known states. For instance, the IP addresses configured to have access to a SQL DB can be any (arbitrary) set of IP addresses. In such scenarios, usually human judgment is initially required to determine whether a particular configuration should be considered 'secure' or not. However, once that is done, it is important to ensure that there is no "stateful drift" from the attested configuration. (E.g., if, in a troubleshooting session, someone adds the IP address of a developer machine to the list, the Continuous Assurance feature should be able to identify the drift and generate notifications/alerts or even trigger 'auto-remediation' depending on the severity of the change).

                                              NEW QUESTION # 451
                                              You use GitHub for source control and Azure Boards for project management. GitHub and Azure Boards are integrated.
                                              You plan to create a pull request in GitHub.
                                              You need to automatically link the request to an existing Azure Boards work item by using the text of AB#<WORKITEMNUMBER>.
                                              To which two elements can you add the text? Each correct answer presents a complete solution.
                                              NOTE: Each correct selection is worth one point.

                                              Explanation
                                              You can add the text "AB#<WORKITEMNUMBER>" to the title or description of the pull request in GitHub, which will automatically link the request to an existing Azure Boards work item with that number.
