Case Study 9 - Munson's Pickles and Preserves Farm
Background
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.
Current Environment
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.
Requirements
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.
Issues
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.

NOTE: Each correct selection is worth one point.

A team 'PNX' has created an Index in the Azure Search service.
Ted has to upload data into the Index.
To carry out from his .Net program he Proposed the following steps:
- Create a SearchlndexClient object to connect to the search index.
- Create a DataContainer that contains the documents which must be
added.
- Create a DataSource instance and set its Container property to the
DataContainer
- Call the Documents.Search method of the SearchlndexClient andpass the DataSource.State Whether the list of steps have fulfilled the requirement?

• A. FALSE
• B. TRUE

A development team is developing an application. The application will be storing its data in Azure Table storage. Below are the fields that are going to be stored in the table
- Region
- Email address
- Phone number
The following snippet of code needs to be completed that would be used to insert a batch of records.

Which of the following will go into Slot2?

• A. TableBatchOperation
• B. TableEntity
• C. TableQuery
• D. TableOperation

Case Study 2 - Coho Winery
LabelMaker app
Coho Winery produces bottles, and distributes a variety of wines globally. You are developer implementing highly scalable and resilient applications to support online order processing by using Azure solutions.
Coho Winery has a LabelMaker application that prints labels for wine bottles. The application sends data to several printers. The application consists of five modules that run independently on virtual machines (VMs). Coho Winery plans to move the application to Azure and continue to support label creation.
External partners send data to the LabelMaker application to include artwork and text for custom label designs.
Data
You identify the following requirements for data management and manipulation:
* Order data is stored as nonrelational JSON and must be queried using Structured Query
Language (SQL).
* Changes to the Order data must reflect immediately across all partitions. All reads to the Order
data must fetch the most recent writes.
You have the following security requirements:
* Users of Coho Winery applications must be able to provide access to documents, resources,
and applications to external partners.
* External partners must use their own credentials and authenticate with their organization's
identity management solution.
* External partner logins must be audited monthly for application use by a user account
administrator to maintain company compliance.
* Storage of e-commerce application settings must be maintained in Azure Key Vault.
* E-commerce application sign-ins must be secured by using Azure App Service authentication
and Azure Active Directory (AAD).
* Conditional access policies must be applied at the application level to protect company content
* The LabelMaker applications must be secured by using an AAD account that has full access to
all namespaces of the Azure Kubernetes Service (AKS) cluster.
LabelMaker app
Azure Monitor Container Health must be used to monitor the performance of workloads that are deployed to Kubernetes environments and hosted on Azure Kubernetes Service (AKS).
You must use Azure Container Registry to publish images that support the AKS deployment.

Calls to the Printer API App fail periodically due to printer communication timeouts.
Printer communications timeouts occur after 10 seconds. The label printer must only receive up to 5 attempts within one minute.
The order workflow fails to run upon initial deployment to Azure.
Order json.
Relevant portions of the app files are shown below. Line numbers are included for reference only.
This JSON file contains a representation of the data for an order that includes a single item.
Order .json


You need to access data from the user claim object in the e-commerce web app.
What should you do first?

• A. Update the e-commerce web app to read the HTTP request header values.
• B. Assign the Contributor RBAC role to the e-commerce web app by using the Resource Manager create role assignment API.
• C. Using the Azure CLI, enable Cross-origin resource sharing (CORS) from the e-commerce checkout API to the e-commerce web app.
• D. Write custom code to make a Microsoft Graph API call from the e-commerce web app.
