Azure App Service with Windows Containers If your app cannot be migrated directly to App Service, consider App Service using Windows Containers, which enables usage of the GAC, COM components, MSIs, full access to .NET FX APIs, DirectX, and more.
You store web access logs data in Azure Blob storage.
You plan to generate monthly reports from the access logs.
You need to recommend an automated process to upload the data to Azure SQL Database every month.
What should you include in the recommendation?
A.
Azure Data Factory
B.
Data Migration Assistant
C.
Microsoft SQL Server Migration Assistant (SSMA)
D.
AzCopy
Azure Data Factory
Explanation:
Azure Data Factory is the platform that solves such data scenarios. It is the cloud-based ETL and data integration service that allows you to create data-driven workflows for orchestrating data movement and transforming data at scale. Using Azure Data Factory, you can create and schedule data-driven workflows (called pipelines) that can ingest data from disparate data stores. You can build complex ETL processes that transform data visually with data flows or by using compute services such as Azure HDInsight Hadoop, Azure Databricks, and Azure SQL Database.
You plan provision a High Performance Computing (HPC) cluster in Azure that will use a third-party scheduler.
You need to recommend a solution to provision and manage the HPC cluster node.
What should you include in the recommendation?
A.
Azure Lighthouse
B.
Azure CycleCloud
C.
Azure Purview
D.
Azure Automation
Azure CycleCloud
Explanation:
You can dynamically provision Azure HPC clusters with Azure CycleCloud. Azure CycleCloud is the simplest way to manage HPC workloads.
Note: Azure CycleCloud is an enterprise-friendly tool for orchestrating and managing High Performance Computing (HPC) environments on Azure. With CycleCloud, users can provision infrastructure for HPC systems, deploy familiar HPC schedulers, and automatically scale the infrastructure to run jobs efficiently at any scale. Through CycleCloud, users can create different types of file systems and mount them to the compute cluster nodes to support HPC workloads.

Your company deploys several virtual machines on-premises and to Azure. ExpressRoute is deployed and configured for on-premises to Azure connectivity. Several virtual machines exhibit network connectivity issues. You need to analyze the network traffic to identify whether packets are being allowed or denied from the Azure virtual machines to the on-premises virtual machines.
Solution: Use Azure Advisor.
Does this meet the goal?
A.
Yes
B.
No
No
You have an on-premises application named App1 that uses an Oracle database.
You plan to use Azure Databricks to transform and load data from App1 to an Azure Synapse Analytics instance.
You need to ensure that the App1 data is available to Databricks.

NOTE: Each correct selection is worth one point.
A.
Azure Data Box Edge
B.
Azure Data Lake Storage
C.
Azure Data Factory
D.
Azure Data Box Gateway
E.
Azure Import/Export service

Azure Import/Export service
You have an Azure subscription that contains the SQL servers shown in the following table.
Your company has an app named App1 that uses data from the on-premises Microsoft SQL Server databases shown in the following table.
App1 and the data are used on the first day of the month only. The data is not expected to grow more than 3% each year.
The company is rewriting App1 as an Azure web app and plans to migrate all the data to Azure.
You need to migrate the data to Azure SQL Database. The solution must minimize costs.
Which service tier should you use?
A.
vCore-based Business Critical
B.
vCore-based General Purpose
C.
DTU-based Standard
D.
DTU-based Basic
vCore-based General Purpose
Explanation: DTU-based Standard supports databases up to 1 TB in size.
You have an Azure subscription that contains an Azure SQL database.
You are evaluating whether to use Azure reservations on the Azure SQL database.
Which tool should you use to estimate the potential savings?
A.
The Purchase reservations blade in the Azure portal
B.
The Advisor blade in the Azure portal
C.
The SQL database blade in the Azure portal
The Purchase reservations blade in the Azure portal
Explanation:
Buy reserved capacity
Sign in to the Azure portal.
Select All services > Reservations.
Select Add and then in the Purchase Reservations pane, select SQL Database to purchase a new reservation for SQL Database.
Fill in the required fields. Existing databases in SQL Database and SQL Managed Instance that match the attributes you select qualify to get the reserved capacity discount. The actual number of databases or managed instances that get the discount depends on the scope and quantity selected.
Review the cost of the capacity reservation in the Costs section.
Select Purchase.
Select View this Reservation to see the status of your purchase.

You plan to deploy an Azure web app named Appl that will use Azure Active Directory (Azure AD) authentication.
App1 will be accessed from the internet by the users at your company. All the users have computers that run Windows 10 and are joined to Azure AD.
You need to recommend a solution to ensure that the users can connect to App1 without being prompted for authentication and can access App1 only from company-owned computers.
What should you recommend for each requirement? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
The developers at your company are building a containerized Python Django app. You need to recommend platform to host the app. The solution must meet the following requirements:
Support autoscaling.
Support continuous deployment from an Azure Container Registry.
Provide built-in functionality to authenticate app users by using Azure Active Directory (Azure AD).
Which platform should you include in the recommendation?
A.
Azure Container instances
B.
an Azure App Service instance that uses containers
C.
Azure Kubernetes Service (AKS)
Azure Kubernetes Service (AKS)
Explanation:
To keep up with application demands in Azure Kubernetes Service (AKS), you may need to adjust the number of nodes that run your workloads. The cluster autoscaler component can watch for pods in your cluster that can't be scheduled because of resource constraints. When issues are detected, the number of nodes in a node pool is increased to meet the application demand. Azure Container Registry is a private registry for hosting container images. It integrates well with orchestrators like Azure Container Service, including Docker Swarm, DC/OS, and the new Azure Kubernetes service. Moreover, ACR provides capabilities such as Azure Active Directory-based authentication, webhook support, and delete operations.
