• Question 291:

  Your on-premises datacenter contains a server that runs Linux and hosts a Java app named App1. App1 has the following characteristics:

  App1 is an interactive app that users access by using HTTPS connections.

  The number of connections to App1 changes significantly throughout the day.

  App1 runs multiple concurrent instances.

  App1 requires major changes to run in a container.

  You plan to migrate App1 to Azure.

  You need to recommend a compute solution for App1. The solution must meet the following requirements:

  The solution must run multiple instances of App1.

  The number of instances must be managed automatically depending on the load.

  Administrative effort must be minimized.

  What should you include in the recommendation?

  A. Azure Batch

  B. Azure App Service

  C. Azure Kubernetes Service (AKS)

  D. Azure Virtual Machine Scale Sets

  Correct Answer: D

  Azure Virtual Machine Scale Sets let you create and manage a group of load balanced VMs. The number of VM instances can automatically increase or decrease in response to demand or a defined schedule. Scale sets provide the following key benefits:

  Easy to create and manage multiple VMs Provides high availability and application resiliency by distributing VMs across availability zones or fault domains Allows your application to automatically scale as resource demand changes Works at large-scale

  Incorrect:

  * Azure Kubernetes Service (AKS)

  Azure Kubernetes Service (AKS) requires more administrative effort-

  Note:

  You can scale applications in Azure Kubernetes Service (AKS).

  Windows and Linux based AKS clusters are supported.

  Cluster node and pod scaling

  As demand for resources change, the number of cluster nodes or pods that run your services automatically scales up or down. You can adjust both the horizontal pod autoscaler or the cluster autoscaler to adjust to demands and only run

  necessary resources.

  Azure Linux nodes

  The Azure Linux container host for AKS is an open-source Linux distribution created by Microsoft, and it's available as a container host on Azure Kubernetes Service (AKS). The Azure Linux container host for AKS provides reliability and

  consistency from cloud to edge across the AKS, AKS-HCI, and Arc products. You can deploy Azure Linux node pools in a new cluster, add Azure Linux node pools to your existing Ubuntu clusters, or migrate your Ubuntu nodes to Azure

  Linux nodes.

  Windows Admin Center manages this server. The company owns an Azure subscription.

  You need to provide an Azure solution to prevent data loss if the file server fails.

  Solution: You decide to register Windows Admin Center in Azure and then configure Azure Backup.

  Would this meet the requirement?

  A. Yes

  B. No

  Correct Answer: A

• Question 295:

  A company is planning on deploying an application onto Azure. The application will be based on the .Net core programming language. The application would be hosted using Azure Web apps. Below is part of the various requirements for the application

  Give the ability to correlate Azure resource usage and the performance data with the actual application configuration and performance data Give the ability to visualize the relationships between application components Give the ability to track requests and exceptions to specific lines of code from within the application Give the ability to actually analyse how uses return to an application and see how often they only select a particular drop-down value

  Which of the following service would be best suited for fulfilling the requirement of “Give the ability to correlate Azure resource usage and the performance data with the actual application configuration and performance data” ?

  A. Azure Application Insights

  B. Azure Service Map

  C. Azure Log Analytics

  D. Azure Activity Log

  Correct Answer: C

• Question 296:

  A company has an on-premises file server cbflserver that runs Windows Server 2019.

  Windows Admin Center manages this server. The company owns an Azure subscription.

  You need to provide an Azure solution to prevent data loss if the file server fails.

  Solution: You decide to create an Azure Recovery Services vault. You then decide to install the Azure Backup agent and then schedule the backup.

  Would this meet the requirement?

  A. Yes

  B. No

  Correct Answer: A

• Question 297:

  You need to recommend a solution that meets the data requirements for App1.

  What should you recommend deploying to each availability zone that contains an instance of App1?

  A. an Azure Cosmos DB that uses multi-region writes

  B. an Azure Data Lake store that uses geo-zone-redundant storage (GZRS)

  C. an Azure SQL database that uses active geo-replication

  D. an Azure Storage account that uses geo-zone-redundant storage (GZRS)

  Correct Answer: A

  Scenario: App1 has the following data requirements:

  1.

  Each instance will write data to a data store in the same availability zone as the instance.

  2.

  Data written by any App1 instance must be visible to all App1 instances.

  Azure Cosmos DB: Each partition across all the regions is replicated. Each region contains all the data partitions of an Azure Cosmos container and can serve reads as well as serve writes when multi-region writes is enabled.

  Incorrect Answers:

  B, D: GZRS protects against failures. Geo-redundant storage (with GRS or GZRS) replicates your data to another physical location in the secondary region to protect against regional outages. However, that data is available to be read only if

  the customer or Microsoft initiates a failover from the primary to secondary region.

  C: Active geo-replication is designed as a business continuity solution that lets you perform quick disaster recovery of individual databases in case of a regional disaster or a large scale outage. Once geo-replication is set up, you can initiate a

  geo-failover to a geo-secondary in a different Azure region. The geo-failover is initiated programmatically by the application or manually by the user.

  A. Configure a long-term retention policy for the database.

  B. Configure Azure Site Recovery.

  C. Use automatic Azure SQL Database backups.

  D. Configure geo-replication of the database.

  Correct Answer: A

  In Azure SQL Database, you can configure a database with a long-term backup retention policy (LTR) to automatically retain the database backups in separate Azure Blob storage containers for up to 10 years https://docs.microsoft.com/en-us/azure/azure-sql/database/long-termretention-overview

• Question 300:

  What should you include in the identity management strategy to support the planned changes?

  A. Deploy domain controllers for corp.fabrikam.com to virtual networks in Azure.

  B. Move all the domain controllers from corp.fabrikam.com to virtual networks in Azure.

  C. Deploy a new Azure AD tenant for the authentication of new RandD projects.

  D. Deploy domain controllers for the rd.fabrikam.com forest to virtual networks in Azure.

  Correct Answer: A

  Directory synchronization between Azure Active Directory (Azure AD) and corp.fabrikam.com must not be affected by a link failure between Azure and the on-premises network. (This requires domain controllers in Azure). Users on the on-premises network must be able to authenticate to corp.fabrikam.com if an Internet link fails. (This requires domain controllers on-premises).
