Q51.  - (Topic 6)

You manage an Azure Web App that has one Web Role instance, and several Worker Role instances. The cloud service has multiple tiers. Different groups develop and maintain each tier.

You need to ensure that the cloud service remains highly available and responsive when the Worker Roles are performing extensive work.

What should you do?

A. Create a resource group.

B. Create an availability set for each tier of the application.

C. Implement auto-scaling for the Worker Roles.

D. Create an availability set with two or more virtual machines.

Answer: C


Q52. CORRECT TEXT - (Topic 6)

You have an Azure subscription.

You plan to deploy five virtual machines that will have similar configurations and will run the same workload.

You need to recommend a solution to ensure the availability of the virtual machines during Azure maintenance periods. At any given time, only one virtual machine can be offline for maintenance.

Q53. DRAG DROP - (Topic 7)

You need to deploy the WGBLoanMaster app by using Azure PowerShell.

Which four Azure PowerShell cmdlets should you run 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:


Q54. DRAG DROP - (Topic 1)

You need to recommend data storage mechanisms for the solution.

What should you recommend? To answer, drag the appropriate data storage mechanism to the correct information type. Each data storage mechanism 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 content.

Answer:

Explanation:

* use Table storage for Contractor information

* Use Blob for Project Images

* Scenario: VanArsdel needs a solution to reduce the number of operations on the contractor information table. Currently, data transfer rates are excessive, and queue length for read/write operations affects performance.

/ A mobile service that is used to access contractor information must have automatically scalable, structured storage

/ Images must be stored in an automatically scalable, unstructured form.

Note: Blob is an acronym for Binary Large object. Basically Blob is a sequence of bytes – just what an application needs. Blob can hold audio, video, email messages, archived files, zip files or a word processing document in a very general way.


Q55.  - (Topic 6)

You are designing an Azure application. The application includes services hosted in

different geographic locations. The service locations may change. You must minimize the cost of communication between services.

You need to recommend an approach for data transmission between your application and Azure services. The solution must minimize administrative effort.

What should you recommend?

A. Azure Table storage

B. Service Bus queue

C. Service Management API

D. Azure Queue storage

Answer: B

Explanation: The cost of ACS transactions is insignificant when performing messaging operations against Service Bus queues. Service Bus acquires one ACS token per a single instance of the messaging factory object. The token is then reused until it expires, after about 20 minutes. Therefore, the volume of messaging operations in Service Bus is not directly proportional to the amount of ACS transactions required to support these operations.

Answer:

Topic 3, Contoso, Ltd

Background

Overview

Contoso, Ltd., manufactures and sells golf clubs and golf balls. Contoso also sells golf accessories under the Contoso Golf and Odyssey brands worldwide.

Most of the company's IT infrastructure is located in the company's Carlsbad, California, headquarters. Contoso also has a sizable third-party colocation datacenter that costs the company USD $30,000 to $40,000 a month. Contoso has other servers scattered around the United States.

Contoso, Ltd., has the following goals:

✑ Move many consumer-facing websites, enterprise databases, and enterprise web services to Azure.

✑ Improve the performance for customers and resellers who are access company websites from around the world.

✑ Provide support for provisioning resources to meet bursts of demand.

✑ Consolidate and improve the utilization of website- and database-hosting resources.

✑ Avoid downtime, particularly that caused by web and database server updating.

✑ Leverage familiarity with Microsoft server management tools.

Infrastructure

Contoso's datacenters are filled with dozens of smaller web servers and databases that run on under-utilized hardware. This creates issues for data backup. Contoso currently backs up data to tape by using System Center Data Protection Manager. System Center Operations Manager is not deployed in the enterprise.

All of the servers are expensive to acquire and maintain, and scaling the infrastructure takes significant time. Contoso conducts weekly server maintenance, which causes

downtime for some of its global offices. Special events, such as high-profile golf tournaments, create a large increase in site traffic. Contoso has difficulty scaling the web- hosting environment fast enough to meet these surges in site traffic.

Contoso has resellers and consumers in Japan and China. These resellers must use applications that run in a datacenter that is located in the state of Texas, in the United States. Because of the physical distance, the resellers experience slow response times and downtime.

Business Requirements Management and Performance Management

✑ Web servers and databases must automatically apply updates to the operating

system and products.

✑ Automatically monitor the health of worldwide sites, databases, and virtual machines.

✑ Automatically back up the website and databases.

✑ Manage hosted resources by using on-premises tools.

Performance

✑ The management team would like to centralize data backups and eliminate the use of tapes.

✑ The website must automatically scale without code changes or redeployment.

✑ Support changes in service tier without reconfiguration or redeployment.

✑ Site-hosting must automatically scale to accommodate data bandwidth and number of connections.

✑ Scale databases without requiring migration to a larger server.

✑ Migrate business critical applications to Azure.

✑ Migrate databases to the cloud and centralize databases where possible.

Business Continuity and Support Business Continuity

✑ Minimize downtime in the event of regional disasters.

✑ Recover data if unintentional modifications or deletions are discovered.

✑ Run the website on multiple web server instances to minimize downtime and support a high service level agreement (SLA).

Connectivity

✑ Allow enterprise web services to access data and other services located on- premises.

✑ Provide and monitor lowest latency possible to website visitors.

✑ Automatically balance traffic among all web servers.

✑ Provide secure transactions for users of both legacy and modern browsers.

✑ Provide automated auditing and reporting of web servers and databases.

✑ Support single sign-on from multiple domains.

Development Environment

You identify the following requirements for the development environment:

✑ Support the current development team's knowledge of Microsoft web development and SQL Service tools.

✑ Support building experimental applications by using data from the Azure deployment and on-premises data sources.

✑ Mitigate the need to purchase additional tools for monitoring and debugging.

✑ System designers and architects must be able to create custom Web APIs without requiring any coding.

✑ Support automatic website deployment from source control.

✑ Support automated build verification and testing to mitigate bugs introduced during builds.

✑ Manage website versions across all deployments.

✑ Ensure that website versions are consistent across all deployments.

Technical Requirement Management and Performance Management

✑ Use build automation to deploy directly from Visual Studio.

✑ Use build-time versioning of assets and builds/releases.

✑ Automate common IT tasks such as VM creation by using Windows PowerShell workflows.

✑ Use advanced monitoring features and reports of workloads in Azure by using existing Microsoft tools.

Performance

✑ Websites must automatically load balance across multiple servers to adapt to varying traffic.

✑ In production, websites must run on multiple instances.

✑ First-time published websites must be published by using Visual Studio and scaled to a single instance to test publishing.

✑ Data storage must support automatic load balancing across multiple servers.

✑ Websites must adapt to wide increases in traffic during special events.

✑ Azure virtual machines (VMs) must be created in the same datacenter when applicable.

Business Continuity and Support Business Continuity

✑ Automatically co-locate data and applications in different geographic locations.

✑ Provide real-time reporting of changes to critical data and binaries.

✑ Provide real-time alerts of security exceptions.

✑ Unwanted deletions or modifications of data must be reversible for up to one month, especially in business critical applications and databases.

✑ Any cloud-hosted servers must be highly available.

Enterprise Support

✑ The solution must use stored procedures to access on-premises SQL Server data from Azure.

✑ A debugger must automatically attach to websites on a weekly basis. The scripts

that handle the configuration and setup of debugging cannot work if there is a delay in attaching the debugger.
