• Question 21:

  DRAG DROP

  You have an Azure subscription that uses Azure Automation State Configuration to manage the configuration of virtual machines.

  You need to identify which nodes are noncompliant.

  How should you complete the query? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.

  Select and Place:

  

  Correct Answer:

  

  Explanation:

  Box 1: Category

  To find nodes that aren't compliant, type the following query.

  AzureDiagnostics

  | where Category == "DscNodeStatus"

  | where OperationName contains "DSCNodeStatusData"

  | where ResultType != "Compliant"

  Filtering details:

  Filter on DscNodeStatusData to return operations for each State Configuration node.

  Filter on DscResourceStatusData to return operations for each DSC resource called in the node configuration applied to that resource.

  Filter on DscResourceStatusData to return error information for any DSC resources that fail.

  Box 2: OperationName

  Box 3: ResultType

• Question 22:

  DRAG DROP

  You have an Azure DevOps pipeline that is used to deploy a Node.js app.

  You need to ensure that the dependencies are cached between builds.

  How should you configure the deployment YAML? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view

  content.

  Correct Answer:

  

  Explanation:

  Box 1: build.sh Conditioning on cache restoration In some scenarios, the successful restoration of the cache should cause a different set of steps to be run. For example, a step that installs dependencies can be skipped if the cache was restored. This is possible using the cacheHitVar task input. Setting this input to the name of an environment variable will cause the variable to be set to true when there's a cache hit, inexact on a restore key cache hit, otherwise it will be set to false. This variable can then be referenced in a step condition or from within a script.

  In the following example, the install-deps.sh step is skipped when the cache is restored:

  YAML

  steps:

  -task: Cache@2

  inputs:

  key: mykey | mylockfile

  restoreKeys: mykey

  path: $(Pipeline.Workspace)/mycache

  cacheHitVar: CACHE_RESTORED

  -

  script: install-deps.sh condition: ne(variables.CACHE_RESTORED, 'true')

  -

  script: build.sh

  Box 2: ne(variables.CACHE_RESTORED, 'true')

  Incorrect:

  *

  always()

  condition: always() # this step will always run, even if the pipeline is canceled

  *

  .integrationtest.sh

  Build base images in integration tests.

  *

  npm install

  npm install downloads a package and it's dependencies.

  When run without arguments, npm install downloads dependencies defined in a package.json file and generates a node_modules folder with the installed modules.

• Question 25:

  DRAG DROP

  You use Git for source control.

  You delete a file, commit the changes, and continue to work.

  You need to recover the deleted file.

  Which three commands should you run in sequence? To answer, move the appropriate commands from the list of commands to the answer area and arrange them in the correct order.

  Select and Place:

  

  Correct Answer:

  

  Explanation:

  Step 1: git log.

  Find the commit SHA of the commit you want to revert to. To look through a log of commits, type git log.

  Step 2: git checkout [hash]~1 --path/to/file

  If you have deleted the file and already committed the changes, you need to use the `git checkout` command to restore the file. First, you need to find out the checksum of the commit that deleted the file, and then check out the file from the

  previous commit.

  This command tells `git` to list all commits, which can be reached from the HEAD, that changed the file `file1.txt`. The `-n 1` option tells `git` to limit the result to only one commit. The output is the checksum of the commit that deleted the file.

  To undo changes on a single file or directory from commit B, but retain them in the staged state:

  git checkout

  Step 3: git restore path/to/file

  To unstage the file but keep your changes:

  git restore --staged

  Note: Recovering Deleted Files with the Command Line

  Recovering a deleted file using the Git command line involves the `git restore` or `git checkout`command. Whenever you modify files in Git—including creating new files, editing, or deleting existing files—the changes start as unstaged. Then

  you stage the changes with the `git add` command, and finally, you commit the changes using the `git commit` command. Git provides ways to recover a deleted file at any point in this life cycle of changes.

  If you have not staged the deletion yet, simply run `git restore ` and the file will be restored from the index.

• Question 26:

  DRAG DROP

  You have a GitHub repository that contains the code for an app named App1.

  App1 depends on a library of functions from a repository at https://github.com/contoso/afeed.

  You need to keep a clone of the afeed repository as a subdirectory of the App1 repository.

  How should you complete the Git command? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view

  content.

  NOTE: Each correct selection is worth one point.

  Select and Place:

  

  Correct Answer:

  

  Explanation:

  Box 1: clone

  git-clone - Clone a repository into a new directory

  Box 2: branch

  --branch

  Instead of pointing the newly created HEAD to the branch pointed to by the cloned repository's HEAD, point to branch instead. In a non-bare repository, this is the branch that will be checked out. --branch can also take tags and

  detaches the HEAD at that commit in the resulting repository.

  Incorrect:

  *

  git pull

  The git pull command is used to fetch and download content from a remote repository and immediately update the local repository to match that content.

  SYNOPSIS

  git pull [] [ […]]

  *

  git-add - Add file contents to the index
