Topic 8, Munson's Pickles and Preserves Farm
Munson's Pickles and Preserves Farm is an agricultural cooperative corporation based in Washington, US, with farms located across the United States. The company supports agricultural production resources by distributing seeds, fertilizers, chemicals, fuel, and farm machinery to the farms.
The company is migrating all applications from an on-premises datacenter to Microsoft Azure. Applications support distributors, farmers, and internal company staff.
Corporate website
* The
company hosts a public website located at http://www.munsonspicklesandpreservesfarm.com. The site supports farmers and distributors who request agricultural production resources.
Farms
* The company created a new customer tenant in the Microsoft Entra admin center to support authentication and authorization for applications.
Distributors
* Distributors
integrate their applications with data that is accessible by using APIs hosted at http://www.
munsonspicklesandpreservesfarm com/api to receive and update resource data.
The application components must meet the following requirements:
Corporate website
* The site must be migrated to Azure App Service.
* Costs must be minimized when hosting in Azure.
* Applications must automatically scale independent of the compute resources.
* All code changes must be validated by internal staff before release to production.
* File transfer speeds must improve, and webpage-load performance must increase.
* All site settings must be centrally stored, secured without using secrets, and encrypted at rest and in transit.
* A queue-based load leveling pattern must be implemented by using Azure Service Bus queues to support high volumes of website agricultural production resource requests.
Farms
* Farmers must authenticate to applications by using Microsoft Entra ID.
Distributors
* The company must track a custom telemetry value with each API call and monitor performance of all APIs.
* API telemetry values must be charted to evaluate variations and trends for resource data.
Internal staff
* App and API updates must be validated before release to production.
* Staff must be able to select a link to direct them back to the production app when validating an app or API update.
* Staff profile photos and email must be displayed on the website once they authenticate to applications by using their Microsoft Entra ID.
Security
* All web communications must be secured by using TLS/HTTPS.
* Web content must be restricted by country/region to support corporate compliance standards
* The principle of least privilege must be applied when providing any user rights or process access rights
* Managed identities for Azure resources must be used to authenticate services that support Microsoft Entra ID authentication.
Corporate website
* Farmers report HTTP 503 errors at the same time as internal staff report that CPU and memory usage are high.
* Distributors report HTTP 502 errors at the same time as internal staff report that average response times and networking traffic are high.
* Internal staff report webpage load sizes are large and take a long time to load.
* Developers receive authentication errors to Service Bus when they debug locally.
Distributors
* Many API telemetry values are sent in a short period of time. Telemetry traffic, data costs, and storage costs must be reduced while preserving a statistically correct analysis of the data points sent by the APIs.
質問 # 42
You are developing a back-end Azure App Service that scales based on the number of messages contained in a Service Bus queue.
A rule already exists to scale up the App Service when the average queue length of unprocessed and valid queue messages is greater than 1000.
You need to add a new rule that will continuously scale down the App Service as long as the scale up condition is not met.
How should you configure the Scale rule? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
正解：
解説：
Explanation:
Box 1: Service bus queue
You are developing a back-end Azure App Service that scales based on the number of messages contained in a Service Bus queue.
Box 2: ActiveMessage Count
ActiveMessageCount: Messages in the queue or subscription that are in the active state and ready for delivery.
Box 3: Count
Box 4: Less than or equal to
You need to add a new rule that will continuously scale down the App Service as long as the scale up condition is not met.
Box 5: Decrease count by

質問 # 44
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.
正解：
解説：
Explanation:
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.
