70-535 | The Abreast of the times Guide To 70-535 exam question

Q3. You manage a cloud service that utilizes an Azure Service Bus queue. You need to ensure that messages that are never consumed are retained. What should you do?

A. Check the MOVE TO THE DEAD-LETTER SUBQUEUE option for Expired Messages in the Azure Portal.

B. From the Azure Management Portal, create a new queue and name it Dead-Letter.

C. Execute the Set-AzureServiceBus PowerShell cmdlet.

D. Execute the New-AzureSchedulerStorageQueueJob PowerShell cmdlet.

Answer: A

Explanation:

Deadlettering u2013 From time to time a message may arrive in your queue that just canu2021t be processed. Each time the message is retrieved for processing the consumer throws an exception and cannot process the message. These are often referred to as poisonous messages and can happen for a variety of reasons, such as a corrupted payload, a message containing an unknown payload inadvertently delivered to a wrong queue, etc. When this happens, you do not want your system to come to grinding to a halt simply because one of the messages canu2021t be processed.

Ideally the message will be set aside to be reviewed later and processing can continue on to other messages in the queue. This process is called u2021Deadletteringu2021 a message and the Service Bus Brokered Messaging supports dead lettering by default. If a message fails to be processed and appears back on the queue ten times it will be placed into a dead letter queue. You can control the number of failures it takes for a message to be dead lettered by setting the MaxDeliveryCount property on the queue. When a message is deadlettered it is actually placed on a sub queue which can be accessed just like any other Service Bus queue. In the example used above the dead letter queue path would be samplequeue/$DeadLetterQueue. By default a message will be moved to the dead letter queue if it fails delivery more than 10 times.

Automatic dead lettering does not occur in the ReceiveAndDelete mode as the message has already been removed from the queue.

Q8. You need to recommend a data storage solution that meets the business continuity requirements. Which two features should you recommend? Each correct answer presents part of the solution.

A. SQL Database Standard

B. Azure Backup

C. SQL Database Premium

D. SQL Database Express

Answer: A,B

Explanation:

From scenario: Disaster recovery and business continuity plans must use a single, integrated service that supports the following features:

* All VMs must be backed up to Azure.

* All on-premises data must be backed up off-site and available for recovery in the event of a disaster.

* Disaster testing must be performed to ensure that recovery times meet management guidelines.

* Fail-over testing must not impact production.

Q9. You need to design the business continuity framework. Which technology should you use?

A. Hyper-V Replica

B. Azure Backup

C. Azure Site Recovery

Q11. Your company is launching a public website that allows users to stream videos. You upload multiple video files to an Azure storage container.

You need to give anonymous users read access to all of the video files in the storage container. What should you do?

A. Edit each blob's metadata and set the access policy to Public Blob.

B. Edit the container metadata and set the access policy to Public Container.

C. Move the files into a container sub-directory and set the directory access level to Public Blob.

D. Edit the container metadata and set the access policy to Public Blob.

Answer: D

Explanation:

You can enable anonymous, public read access to a container and its blobs in Azure Blob storage. By doing so, you can grant read-only access to these resources without sharing your account key, and without requiring a shared access signature (SAS).

To set permissions to public read access for blobs only, set the PublicAccess property to

BlobContainerPublicAccessType.Blob.

Q12. You are designing a Windows Azure application. Messages will be placed into a Windows Azure Queue and then processed by a worker role. There is no requirement for adherence to the Windows Azure Service Level Agreement (SLA).

You need to recommend an approach for concurrently processing messages while minimizing compute cost. What should you recommend?

A. A single role instance that processes messages individually

B. A single role instance with multithreaded request processing

C. Multiple role instances that process messages individually

D. Multiple role instances, each with multithreaded request processing

Answer: B

Explanation:

Threads: When the request for the background work comes in, the web role starts as many threads as necessary (or queues the individual work items to the thread pool). In this option, we would configure a larger instance during the heavy workload, because these threads could require a lot of memory.

Incorrect:

Not C, not D: SLA would require multiple role instances.
