Microsoft AZ-305 Exam Domains Q&A

Certified instructors verify every question for 100% accuracy, providing detailed, step-by-step explanations for each.

Question 1 Microsoft AZ-305
QUESTION DESCRIPTION:

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 & Rationale:

Answer: A

Explanation:

Scenario: App1 has the following data requirements:

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

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.

[Reference:, https://docs.microsoft.com/en-us/azure/cosmos-db/high-availability, , , , ]

Question 2 Microsoft AZ-305
QUESTION DESCRIPTION:

You plan to migrate App1 to Azure.

You need to recommend a network connectivity solution for the Azure Storage account that will host the App1 data. The solution must meet the security and compliance requirements.

What should you include in the recommendation?

  • A.

    a private endpoint

  • B.

    a service endpoint that has a service endpoint policy

  • C.

    Azure public peering for an ExpressRoute circuit

  • D.

    Microsoft peering for an ExpressRoute circuit

Correct Answer & Rationale:

Answer: A

Explanation:

Private Endpoint securely connect to storage accounts from on-premises networks that connect to the VNet using VPN or ExpressRoutes with private-peering.

Private Endpoint also secure your storage account by configuring the storage firewall to block all connections on the public endpoint for the storage service.

https://docs.microsoft.com/en-us/azure/expressroute/expressroute-faqs#microsoft-peering

Question 3 Microsoft AZ-305

As an administrator, you can lock a subscription, resource group, or resource to prevent other users in your organization from accidentally deleting or modifying critical resources. The lock overrides any permissions the user might have.

[Reference:, https://docs.microsoft.com/en-us/azure/azure-resource-manager/management/lock-resources, , , , ]

  • D.

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

Correct Answer & Rationale:

Answer: B

Explanation:

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)
