NEW QUESTION # 137
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.
Answer:
Explanation:
Explanation
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.

NEW QUESTION # 138
You are developing an ASP.NET Core Web API web service. The web service uses Azure Application Insights for all telemetry and dependency tracking. The web service reads and writes data to a database other than Microsoft SQL Server.
You need to ensure that dependency tracking works for calls to the third-party database.
Which two Dependency Telemetry properties should you store in the database? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
Answer: A,C
Explanation:
Example:
public async Task Enqueue(string payload)
{
// StartOperation is a helper method that initializes the telemetry item
// and allows correlation of this operation with its parent and children.
var operation = telemetryClient.StartOperation<DependencyTelemetry>("enqueue " + queueName);
operation.Telemetry.Type = "Azure Service Bus";
operation.Telemetry.Data = "Enqueue " + queueName;
var message = new BrokeredMessage(payload);
// Service Bus queue allows the property bag to pass along with the message.
// We will use them to pass our correlation identifiers (and other context)
// to the consumer.
message.Properties.Add("ParentId", operation.Telemetry.Id);
message.Properties.Add("RootId", operation.Telemetry.Context.Operation.Id);

NEW QUESTION # 139
Case Study 1 - Litware Inc
Background
You are a developer for Litware Inc., a SaaS company that provides a solution for managing employee expenses. The solution consists of an ASP.NET Core Web API project that is deployed as an Azure Web App.
Overall architecture
Employees upload receipts for the system to process. When processing is complete, the employee receives a summary report email that details the processing results. Employees then use a web application to manage their receipts and perform any additional tasks needed for reimbursement.
Receipt processing
Employees may upload receipts in two ways:
* Uploading using an Azure Files mounted folder
* Uploading using the web application
Data Storage
Receipt and employee information is stored in an Azure SQL database.
Documentation
Employees are provided with a getting started document when they first use the solution. The documentation includes details on supported operating systems for Azure File upload, and instructions on how to configure the mounted folder.
Solution details
Users table
Web Application
You enable MSI for the Web App and configure the Web App to use the security principal name WebAppIdentity.
Processing
Processing is performed by an Azure Function that uses version 2 of the Azure Function runtime.
Once processing is completed, results are stored in Azure Blob
Storage and an Azure SQL database. Then, an email summary is sent to the user with a link to the processing report. The link to the report must remain valid if the email is forwarded to another user.
Logging
Azure Application Insights is used for telemetry and logging in both the processor and the web application. The processor also has TraceWriter logging enabled.
Application Insights must always contain all log messages.
Requirements
Receipt processing
Concurrent processing of a receipt must be prevented.
Disaster recovery
Regional outage must not impact application availability. All DR operations must not be dependent on application running and must ensure that data in the DR region is up to date.
Security
* Users' SecurityPin must be stored in such a way that access to the database does not allow the
viewing of SecurityPins. The web application is the only system that should have access to SecurityPins.
* All certificates and secrets used to secure data must be stored in Azure Key Vault.
* You must adhere to the principle of least privilege and provide privileges which are essential to
perform the intended function.
* All access to Azure Storage and Azure SQL database must use the application's Managed
Service Identity (MSI)
* Receipt data must always be encrypted at rest.
* All data must be protected in transit
* User's expense account number must be visible only to logged in users. All other views of the
expense account number should include only the last segment, with the remaining parts obscured.
* In the case of a security breach access to all summary reports must be revoked without
impacting other parts of the system.
Issues
Upload format issue
Employees occasionally report an issue with uploading a receipt using the web application. They report that when they upload a receipt using the Azure File Share, the receipt does not appear in their profile. When this occurs, they delete the file in the file share and use the web application, which returns a 500 Internal Server error page.
Capacity issue
During busy periods, employees report long delays between the time they upload the receipt and when it appears in the web application.
Log capacity issue
Developers report that the number of log message in the trace output for the processor is too high, resulting in lost log messages.
Application code
Processing.cs
Database.cs
ReceiptUploader.cs
ConfigureSSE.ps1
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this question, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You need to ensure that the SecurityPin security requirements are met.
Solution: Enable Always Encrypted for the SecurityPin column using a certificate based on a trusted certificate authority. Update the Getting Started document with instructions to ensure that the certificate is installed on user machines.
Does the solution meet the goal?
Answer: B
Explanation:
Enable Always Encrypted is correct, but only the WebAppIdentity service principal should be given access to the certificate.
Scenario: Users' SecurityPin must be stored in such a way that access to the database does not allow the viewing of SecurityPins. The web application is the only system that should have access to SecurityPins.
