  You are a developer for a company that provides a bookings management service in the tourism industry. You are implementing Azure Search for the tour agencies listed in your company's solution.

  You create the index in Azure Search. You now need to use the Azure Search .NET SDK to import the relevant data into the Azure Search service.

  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.

  Correct Answer:

  

  1.

  The index needs to be populated. To do this, we will need a SearchIndexClient. There are two ways to obtain one: by constructing it, or by calling Indexes.GetClient on the SearchServiceClient. Here we will use the first method.

  2.

  Create the indexBatch with the documents

  Something like:

  var hotels = new Hotel[];

  {

  new Hotel()

  {

  HotelId = "3",

  BaseRate = 129.99,

  Description = "Close to town hall and the river"

  } }; … var batch = IndexBatch.Upload(hotels);

  3. The next step is to populate the newly-created index

  Example:

  var batch = IndexBatch.Upload(hotels);

  try

  {

  indexClient.Documents.Index(batch);

  }

  You develop an Azure solution that uses Cosmos DB.

  The current Cosmos DB container must be replicated and must use a partition key that is optimized for queries.

  You need to implement a change feed processor solution.

  Which change feed processor components should you use? To answer, drag the appropriate components to the correct requirements. Each component 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 the content.

  NOTE: Each correct selection is worth one point.

  Select and Place:

  

  Correct Answer:

  

  Box 1: The monitored container

  The monitored container has the data from which the change feed is generated. Any inserts and updates to the monitored container are reflected in the change feed of the container.

  Box 2: The lease container

  The lease container acts as a state storage and coordinates processing the change feed across multiple workers. The lease container can be stored in the same account as the monitored container or in a separate account.

  Box 3: The host: A host is an application instance that uses the change feed processor to listen for changes. Multiple instances with the same lease configuration can run in parallel, but each instance should have a different instance name.

  Box 4: The delegate

  The delegate is the code that defines what you, the developer, want to do with each batch of changes that the change feed processor reads.

  You are maintaining an existing application that uses an Azure Blob GPv1 Premium storage account. Data older than three months is rarely used.

  Data newer than three months must be available immediately. Data older than a year must be saved but does not need to be available immediately.

  You need to configure the account to support a lifecycle management rule that moves blob data to archive storage for data not modified in the last year.

  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.

  Select and Place:

  

  Correct Answer:

  

  Step 1: Upgrade the storage account to GPv2

  Object storage data tiering between hot, cool, and archive is supported in Blob Storage and General Purpose v2 (GPv2) accounts. General Purpose v1 (GPv1) accounts don't support tiering.

  You can easily convert your existing GPv1 or Blob Storage accounts to GPv2 accounts through the Azure portal.

  Step 2: Copy the data to be archived to a Standard GPv2 storage account and then delete the data from the original storage account

  Step 3: Change the storage account access tier from hot to cool

  Note: Hot - Optimized for storing data that is accessed frequently.

  Cool - Optimized for storing data that is infrequently accessed and stored for at least 30 days.

  Archive - Optimized for storing data that is rarely accessed and stored for at least 180 days with flexible latency requirements, on the order of hours.

  Only the hot and cool access tiers can be set at the account level. The archive access tier can only be set at the blob level.
