You are Implementing an Azure solution that uses Azure Cosmos DB and the latest Azure Cosmos DB SDK. You add a change feed processor to a new container instance.
You attempt to lead a batch of 100 documents. The process falls when reading one of the documents. The solution must monitor the progress of the change feed processor instance on the new container as the change feed is read. You must prevent the change feed processor from retrying the entire batch when one document cannot be read.
You need to implement the change feed processor to read the documents.

You develop a gateway solution for a public facing news API.
The news API back end is implemented as a RESTful sen/ice and hosted in an Azure App Service instance.
You need to configure back-end authentication for the API Management service instance. Which target and gateway credential type should you use? To answer, drag the appropriate
values to the correct parameters. 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.
Solution:
Box 1: Azure Resource Box 2: Client cert
API Management allows to secure access to the back-end service of an API using client certificates.

HOTSPOT - (Topic 8)
A company develops a series of mobile games. All games use a single leaderboard service.
You have the following requirements:
•Code should be scalable and allow for growth.
•Each record must consist of a playedId, gameId, score, and time played.
•When users reach a new high score, the system will save the new score using the SaveScore function below.
•Each game is assigned and Id based on the series title.
You have the following code. (Line numbers are included for reference only.)
You store customer information in an Azure Cosmos database. The following data already exists in the database:
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE:Each correct selection is worth one point.
Solution:
Box 1: Yes
Code for CosmosDB, example:
// Parse the connection string and return a reference to the storage account. CloudStorageAccount storageAccount = CloudStorageAccount.Parse( CloudConfigurationManager.GetSetting("StorageConnectionString"));
// Create the table client.
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
// Retrieve a reference to the table.
CloudTable table = tableClient.GetTableReference("people");
// Create the TableOperation object that inserts the customer entity. TableOperation insertOperation = TableOperation.Insert(customer1);
Box 2: No
A new record will always be added as TableOperation.Insert is used, instead of TableOperation.InsertOrReplace.
Box 3: No
No partition key is used. Box 4: Yes

You need to authenticate the user to the corporate website as indicated by the architectural diagram.
Which two values should you use? Each correct answer presents part of the solution.
NOTE:Each correct selection is worth one point.
Correct Answer:
AD
Claims in access tokens
JWTs (JSON Web Tokens) are split into three pieces:
✑ Header - Provides information about how to validate the token including information about the type of token and how it was signed.
✑ Payload - Contains all of the important data about the user or app that is attempting to call your service.
✑ Signature - Is the raw material used to validate the token.
Your client can get an access token from either the v1.0 endpoint or the v2.0 endpoint using a variety of protocols.
Scenario: User authentication (see step 5 below)
The following steps detail the user authentication process:
✑ The user selects Sign in in the website.
✑ The browser redirects the user to the Azure Active Directory (Azure AD) sign in page.
✑ The user signs in.
✑ Azure AD redirects the user’s session back to the web application. The URL includes an access token.
✑ The web application calls an API and includes the access token in the authentication header. The application ID is sent as the audience (‘aud’) claim in the access token.
✑ The back-end API validates the access token.

You are developing an application to store millions of images in Azure blob storage. The images are uploaded to an Azure blob storage container named companyimages contained in an Azure blob storage account named companymedia. The stored images are uploaded with multiple blob index tags across multiple blobs in the container.
You must find all blobs whose tags match a search expression in the container. The search expression must evaluate an index tag named status with a value of final.
You need to construct the GET method request URL
How should you complete the URI? To answer, drag the appropriate parameters to the correct request URI targets. Each parameter 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.
