                                  問題 #201
                                  The settings for a container in an Azure Cosmos DB Core (SQL) API account are configured as shown in the following exhibit.

                                  Which statement describes the configuration of the container?

                                  答案：C

                                  解題說明：
                                  When DefaultTimeToLive is -1 then your Time to Live setting is On (No default) Time to Live on a container, if present and the value is set to "-1", it is equal to infinity, and items don't expire by default.
                                  Time to Live on an item:
                                  This Property is applicable only if DefaultTimeToLive is present and it is not set to null for the parent container.
                                  If present, it overrides the DefaultTimeToLive value of the parent container.

                                  問題 #202
                                  You have an Azure Cosmos DB container named container! that has a provisioned throughput and two physical partitions. You monitor the following metrics for container1
                                  * Normalized RU consumption
                                  * The percentage of requests that have an HTTP status code of 429
                                  You need to confirm that container1 is configured to maximize resource utilization.
                                  What are the optimal values for each metric? To answer, select the appropriate options in the answer area.
                                  NOTE: Each correct selection is worth one point.

                                  答案：

                                  Explanation:


                                  問題 #203
                                  You have an Azure Resource Manager (ARM) template that provisions Azure Cosmos DB accounts and databases. The accounts are deployed to a single Azure region. The databases have provisioned throughput configured. The name of the region, the type of database throughput, and the throughput value are defined as template parameters.
                                  You need to modify some of the Azure Cosmos DB accounts and databases based on the following scenarios:
                                  * Scenario 1: Add a read region and increase the database throughput.
                                  * Scenario 2: Change the provisioned database throughput to autoscale.
                                  The solution must minimize administrative effort and the duration of the modifications.
                                  What should you use for each scenario? To answer, select the appropriate options in the answer area.
                                  NOTE: Each correct selection is worth one point.

                                  Explanation:


                                  問題 #204
                                  You have an Azure Cosmos DB for NoSQL account.
                                  The change feed is enabled on a container named invoice.
                                  You create an Azure function that has a trigger on the change feed.
                                  What is received by the Azure function?

                                  答案：B

                                  解題說明：
                                  According to the Azure Cosmos DB documentation12, the change feed is a persistent record of changes to a container in the order they occur. The change feed outputs the sorted list of documents that were changed in the order in which they were modified.
                                  The Azure function that has a trigger on the change feed receives all the properties of the updated items2. The change feed does not include the original items or only the changed properties. The change feed also includes some system-defined properties such as _ts (the last modified timestamp) and _lsn (the logical sequence number)3.
                                  Therefore, the correct answer is:


                                  問題 #205
                                  You have an app that stores data in an Azure Cosmos DB Core (SQL) API account The app performs queries that return large result sets.
                                  You need to return a complete result set to the app by using pagination. Each page of results must return 80 items.
                                  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.

                                  答案：

                                  解題說明：

                                  Explanation

                                  Step 1: Configure the MaxItemCount in QueryRequestOptions
                                  You can specify the maximum number of items returned by a query by setting the MaxItemCount. The MaxItemCount is specified per request and tells the query engine to return that number of items or fewer.
                                  Box 2: Run the query and provide a continuation token
                                  In the .NET SDK and Java SDK you can optionally use continuation tokens as a bookmark for your query's progress. Azure Cosmos DB query executions are stateless at the server side and can be resumed at any time using the continuation token.
                                  If the query returns a continuation token, then there are additional query results.
                                  Step 3: Append the results to a variable
