You are developing an Azure cloud service for a company. The cloud service monitors a queue for incoming messages and then processes invoices based on the contents of these messages. Some messages are formed incorrectly and cause exceptions. There is no time limit for how long the service takes to process an individual message. All messages must be processed at least once by using the ProcessMessage method. Messages must not be processed more than twice by using the ProcessMessage method. Messages that fail normal processing must be processed by using the ProcessPoisonMessage method. You need to configure message processing. How should you complete the relevant code? To answer, select the appropriate option or options in the answer area.
You develop a service that runs on a worker role in Azure. The service caches a large amount of data from a database at startup. The service has a configuration file that includes two settings named ConnectionString and SleepInterval. The service must restart when the value of the ConnectionString setting changes. The service must NOT restart when the value of the SleepInterval setting changes. You have the following code. Line numbers are for reference only.
You need to configure the service. Which code segment should you insert at line 21?
A. Option A
B. Option B
C. Option C
D. Option D
You develop a web application that uses table storage in Azure. You create a storage account named Contoso that stores a table named CityPopulationData. The web application stores entities in this table. You need to query the table data by using OData. Which URL should you use?
Case Study – File Tax-Related Document
You are developing an Azure solution that individuals and small businesses will use to prepare and file tax-related documents.
The solution must provide a way for customers to enter personal and demographic information. Customers must be able to upload income documents and related documents to the solution.
The solution must provide reports and summary documents for customers in PDF format.
Scope and Device Accessibility
The solution must support two operational modes: On-Peak and Off-Peak.
On-Peak is defined as the first quarter of a year.
Off-Peak is defined as the other three quarters of a year. Customers must be able to access the solution by using desktop computers, laptop computers, mobile devices, and tablets.
High Availability and Business Continuity
The solution must be available at all times. When the solution transitions between Off-Peak mode and On-Peak mode, solution availability must not be affected.
Disaster recovery must be established for the customers’ stored data.
The solution must log relevant diagnostic data that can be used to troubleshoot the cloud service.
The solution must scale out while transitioning from Off-Peak mode to On-Peak mode.
The solution must use cloud resources optimally to minimize operating costs.
Storage and Security
The solution must be secure to prevent any anonymous access (including read access) to the customers’ tax documents.
The solution must extend the developers’ on-premises network into Azure.
The logical design for the solution is shown in the following exhibit.
The solution must have two roles: a web role and worker role. The web interface of the solution uses a web role to accept and send user input and any related documents.
The worker role must access the stored data and prepare the tax documents in the background.
The solution must support a minimum of 10 role instances. When the solution is in On-Peak mode, each role instance must be allocated at least 6 GB of memory.
The memory can be scaled down to 3 GB when the solution is in Off-Peak mode.
The solution must cache documents locally. The cache does not need to be refreshed during the lifecycle of the worker role.
Role instances that are running should not be affected by topology changes such as an increase in instance count.
The web role must store documents in blob storage. A SQL database is used to store customer information. The worker role must use queues to process the final tax documents.
Performance and Scalability
When the solution is in Off-Peak mode, it must support at least 150 concurrent database sessions, and the maximum size of the database is 50 GB. When the solution is in On- Peak mode, it must support 750 concurrent database sessions, and the maximum size of the database is 300 GB. Geo-replication must be enabled and must be configurable by using the Azure management portal.
The solution must install the software that is necessary to generate PDF documents on the server. The software will be provided as a Windows Installer package.
Solution errors and warnings that occur in a web role must be logged. The worker role must log any crash dump files. Detailed information about errors and their context must be collected so that the environment in which errors occurred can be simulated locally.
At the time that a customer’s tax information and documents are accepted, the solution must send an email to the customer. The email contains a secure hyperlink that the customer can use to upload any additional necessary documents. The customer is asked to upload these documents within 48 hours. If the customer does not upload the documents within 48 hours, the solution should not issue a new hyperlink. The solution must send an email to the customer to remind the customer to use the original hyperlink to upload any additional necessary documents.
The solution must use a cross-premises secure network.
The network must be configurable by using the Azuremanagement portal.
Relevant portions of the solution files are shown in the following code segments. Line numbers in the code segments are included for reference only and include a two-character prefix that denotes the specific file to which they belong.
You need to meet the performance and scalability requirements. Which SQL Database configuration should you use?
A. Use the S1 performance level for On-Peak mode.
B. Use the P2 performance level for On-Peak mode.
C. Use the S2 performance level for On-Peak mode.
D. Use the PI performance level for On-Peak mode.
You have a WebJob object that runs as part of an Azure website. The WebJob object uses features from the Azure SDK for .NET. You use a well-formed but invalid storage key to create the storage account that you pass into the UploadDataToAzureStorage method. The WebJob object contains the following code segment. Line numbers are included for reference only.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
You are migrating an existing solution to Azure. The solution includes a user interface tier and a database tier. The user interface tier runs on multiple virtual machines (VMs). The user interface tier has a website that uses Node.js. The user interface tier has a background process that uses Python. This background process runs as a scheduled job. The user interface tier is updated frequently. The database tier uses a self-hosted MySQL database. The user interface tier requires up to 25 CPU cores. You must be able to revert the user interface tier to a previous version if updates to the website cause technical problems. The database requires up to 50 GB of memory. The database must run in a single VM. You need to deploy the solution to Azure. What should you do first?
A. Deploy the entire solution to an Azure website. Use a web job that runs continuously to host the database.
B. Deploy the database to a VM that runs Windows Server on the Standard tier.
C. Deploy the entire solution to an Azure website. Run the database by using the Azure data management services.
D. Deploy the user interface tier to a VM. Use multiple availability sets to continuously deploy updates from Microsoft Visual Studio Online.
You create a software-as-a-service (SaaS) application. Websites, cloud services, and virtual machines (VMs) read common data values from the database for the application. The application does not scale efficiently. All VMs, websites, and cloud services must read from the same data source. You need to design a cache solution for the SaaS application. What should you do?
A. Deploy a cache by using Azure Redis Cache. Access the cache from the websites, cloud services, and VMs.
B. Configure a cache by using ASP.NET. Access the cache from the websites, cloud services, and VMs.
C. Use Azure Redis Cache to deploy one cache for each website, one cache for each cloud service, and one cache for each VM. Configure each cache to ensure that data is consistent in all the cache instances.
D. Deploy a cache by using Azure Redis Cache. Configure the cache to use database connection strings.
Drag and Drop Question
You create a new web application by using a single Azure website deployment. The deployment uses the shared web hosting plan. User activity varies significantly and unpredictably. The application must automatically scale to a maximum of eight virtual machines based on CPU utilization. You need to configure the environment. In the Azure management portal, 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.
