You plan to deploy multiple instances of an Azure web app across several Azure regions. You need to design an access solution for the app. The solution must meet the following replication requirements:
• Support rate limiting
• Balance requests between all instances.
• Ensure that users can access the app in the event of a regional outage
Solution: You use Azure Load Balancer to provide access to the app.
Does this meet the goal?
A.
Yes
B.
No
No
You are developing a sales application that will contain several Azure cloud services and will handle different components of a transaction. Different cloud services will process customer orders, billing, payment, inventory, and shipping. You need to recommend a solution to enable the cloud services to asynchronously communicate transaction information by using REST messages. What should you include in the recommendation?
A.
Azure Service Bus
B.
Azure Blob storage
C.
Azure Notification Hubs
D.
Azure Application Gateway
Azure Service Bus
Service Bus is a transactional message broker and ensures transactional integrity for all internal operations against its message stores. All transfers of messages inside of Service Bus, such as moving messages to a dead-letter queue or automatic forwarding of messages between entities, are transactional.
Reference:
https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-transactions " Service Bus offers a reliable and secure platform for asynchronous transfer of data and state." ... "Service Bus supports standard AMQP 1.0 and HTTP/REST protocols."

You need to deploy resources to host a stateless web app in an Azure subscription. The solution must meet the following requirements:
• Provide access to the full .NET framework.
• Provide redundancy if an Azure region fails.
• Grant administrators access to the operating system to install custom application dependencies.
Solution: You deploy an Azure virtual machine to two Azure regions, and you deploy an Azure Application Gateway.
Does this meet the goal?
A.
Yes
B.
No
No
You need to deploy two Azure virtual machines to two Azure regions, but also create a Traffic Manager profile.
Your company has offices in New York City, Sydney, Paris, and Johannesburg.
The company has an Azure subscription.
You plan to deploy a new Azure networking solution that meets the following requirements:
• Connects to ExpressRoute circuits in the Azure regions of East US, Southeast Asia, North Europe, and South Africa
• Minimizes latency by supporting connections in three regions
• Supports Site-to-Site VPN connections
• Minimizes costs
You need to identify the minimum number of Azure Virtual WAN hubs that you must deploy, and which virtual WAN SKU to use. What should you identify? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
You are designing a large Azure environment that will contain many subscriptions.
You plan to use Azure Policy as part of a governance solution. To which three scopes can you assign Azure Policy definitions? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A.
management groups
B.
subscriptions
C.
Azure Active Directory (Azure AD) tenants
D.
resource groups
E.
Azure Active Directory (Azure AD) administrative units
F.
compute resources
management groups
resource groups
Azure Active Directory (Azure AD) administrative units
Explanation:
Azure Policy evaluates resources in Azure by comparing the properties of those resources to business rules. Once your business rules have been formed, the policy definition or initiative is assigned to any scope of resources that Azure supports, such as management groups, subscriptions, resource groups, or individual resources.
You have a multi-tier app named Appl and an Azure SQL database named SQL l. The backend service Of Appl writes data to Users use the Appl client to read the data from SQL 1.
During periods of high utilization the users experience delays retrieving the data. You need to minimize how long it takes for data requests. What should you include in the solution?
A.
Azure Synapse Analytics
B.
Azure Content Delivery Network (CON)
C.
Azure Data Factory
D.
Azure Cache for Redis
Azure Cache for Redis
You have an application named App1. App1 generates log files that must be archived for five years. The log files must be readable by App1 but must not be modified.
Which storage solution should you recommend for archiving?
A.
Ingest the log files into an Azure Log Analytics workspace
B.
Use an Azure Blob storage account and a time-based retention policy
C.
Use an Azure Blob storage account configured to use the Archive access tier
D.
Use an Azure file share that has access control enabled
Use an Azure Blob storage account and a time-based retention policy
Explanation:
Immutable storage for Azure Blob storage enables users to store business-critical data objects in a WORM (Write Once, Read Many) state.
Immutable storage supports:
Time-based retention policy support: Users can set policies to store data for a specified interval. When a time-based retention policy is set, blobs can be created and read, but not modified or deleted. After the retention period has expired, blobs can be deleted but not overwritten.
