Explanation:

Box 1: Create a service namespace under Service Bus

Box 2: Obtain the default management credentials for the namespace. Box 3: Configure the application to use Service Bus Relay

Box 4: Configure Service Bus Queue

Note:

Box 1: Create a service namespace under Service Bus

To begin using Service Bus queues in Azure, you must first create a service namespace. A

namespace provides a scoping container for addressing Service Bus resources within your application.

Box 2: Obtain the default management credentials for the namespace.

In order to perform management operations, such as creating a queue on the new namespace, you must obtain the management credentials for the namespace.

Box 3: Configure the application to use Service Bus Relay

When you create an application that uses Service Bus, you must add a reference to the Service Bus assembly and include the corresponding namespaces.

The Service Bus NuGet package is the easiest way to get the Service Bus API and to configure your application with all of the Service Bus dependencies.

After installing this package you are now ready to write code for Service Bus.

Box 4: Configure Service Bus Queue This would include:

* set up a Service Bus connection string

* create a queue

* provide code to send/receive messages from the queue

Topic 2, Trey Research (NEW)

Background

You are an architect for Trey Research Inc., a software as a service (SaaS) company. The company is developing a new product named Tailspin for consumer and small business financial monitoring. The product will be offered as an API to banks and financial instructions. Banks and financial institutions will integrate Tailspin into their own online banking offerings.

All employees of Trey Research are members of an Active Directory Domain Services (AD DS) group named TREY.

Technical Requirement Architecture

All application and customer data will be stored in Azure SQL Database instances.

API calls that modify data will be implemented as queue messages in an Azure Storage Queue. Queue messages must expire after 90 minutes.

Security

The solution has the following security requirements:

u2711 Common security issues such as SQL injection and XSS must be prevented.

u2711 Database-related security issues must not result in customers' data being exposed.

u2711 Exposure of application source code and deployment artifacts must not result in customer data being exposed.

Every 90 days, all application code must undergo a security review to ensure that new or changed code does not introduce a security risk.

Remote code execution in the Web App must not result in the loss of security secrets.

Auditing, Monitoring, Alerting

The solution has the following requirements for auditing, monitoring, and alerting:

u2711 Changes to administrative group membership must be auditable.

u2711 Operations involving encryption keys must be auditable by users in the Azure Key Vault Auditors user role.

u2711 Resources must have monitoring and alerting configured in Azure Security Center.

Authorization, authentication

The solution has the following authentication and authorization requirements:

u2711 Azure Active Directory (Azure AD) must be used to authenticate users.

u2711 Compromised user accounts should be disabled as quickly as possible.

u2711 Only employees of Trey Research Inc. should be able to address automated security recommendations.

Service Level agreement

Failure of any one Azure region must not impact service availability. Customer data must not be lost once accepted by the application.

Performance, resource utilization

The solution must meet the following performance and resource usage requirements:

u2711 Azure costs must be minimized.

u2711 Application performance must remain level, regardless of the geographic location of users.

u2711 All application diagnostic and activity logs must be captured without loss.

u2711 Compute resources must be shared across all databases used by the solution.

Answer: D

Explanation:

Service Bus queues are part of a broader Azure messaging infrastructure that supports queuing as well as publish/subscribe, Web service remoting, and integration patterns. Service Bus Queue support Push-style API (while Azure Queue messaging does not).

Incorrect:

Not A: Notification Hub is only used to push notification, not for processing requests. Not B As a solution architect/developer, you should consider using Azure Queues when:

* Your application must store over 80 GB of messages in a queue, where the messages have a lifetime shorter than 7 days.

* Your application wants to track progress for processing a message inside of the queue. This is useful if the worker processing a message crashes. A subsequent worker can then use that information to continue from where the prior worker left off.

You require server side logs of all of the transactions executed against your queues. Not C: To process the messages we do not need push notification.
