Correct Answer:

The process to associate an automated test with a test case is:

Create a test project containing your automated test. What types of tests are supported?

Check your test project into an Azure DevOps or Team Foundation Server (TFS) repository.

Create a build pipeline for your project, ensuring that it contains the automated test. What are the differences if I am still using a XAML build?

Use Visual Studio Enterprise or Professional 2017 or a later version to associate the automated test with a test case as shown below. The test case must have been added to a test plan that uses the build you just defined.

Explanation:

Box 1: MAJOR Semantic Versioning 2.0.0 Summary Given a version number MAJOR.MINOR.PATCH, increment the:

MAJOR version when you make incompatible API changes

Note: Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

Box 2: Minor How should I handle deprecating functionality? Deprecating existing functionality is a normal part of software development and is often required to make forward progress. When you deprecate part of your public API, you should do two things: (1) update your documentation to let users know about the change, (2) issue a new minor release with the deprecation in place. Before you completely remove the functionality in a new major release there should be at least one minor release that contains the deprecation so that users can smoothly transition to the new API.

Box 3: Minor MINOR version when you add functionality in a backwards compatible manner

Incorrect:

* Patch PATCH version when you make backwards compatible bug fixes

Reference: https://semver.org/

Correct Answer:

Box 1: timestamp >= ago(1hr)

Add a time filter to the query

You can also define your own time range by adding a time filter to the query. It's best to place the time filter immediately after the table name:

SecurityEvent

| where TimeGenerated > ago(30m)

| where toint(Level) >= 10

In the preceding time filter, ago(30m) means "30 minutes ago." This query returns records from only the last 30 minutes, which is expressed as, for example, 30m. Other units of time includ

Box 2: project

Use project and extend to select and compute columns

Use project to select specific columns to include in the results:

SecurityEvent

| top 10 by TimeGenerated

| project TimeGenerated, Computer, Activity

Correct Answer: B

The options you can choose for a queuing policy are:

1.

Number of parallel deployments

2.

If you specify a maximum number of deployments, two more options appear:

-Deploy all in sequence

- Deploy latest and cancel the others: Use this option if you are producing releases faster than builds, and you only want to deploy the latest build. Incorrect Answers:

C: Release gates allow automatic collection of health signals from external services, and then promote the release when all the signals are successful at the same time or stop the deployment on timeout. Typically, gates are used in connection with incident management, problem management, change management, monitoring, and external approval systems.

Correct Answer: A

Secure and Manage Open Source Software

Black Duck helps organizations identify and mitigate open source security, license compliance and code-quality risks across application and container portfolios.

Black Duck Hub and its plugin for Team Foundation Server (TFS) allows you to automatically find and fix open source security vulnerabilities during the build process, so you can proactively manage risk. The integration allows you to receive

alerts and fail builds when any Black Duck Hub policy violations are met.
