Exam AZ-500 topic 2 question 3 discussion

Here is hint in the question itself--- "You need to configure the environment to support the planned authentication" They are asking to "configure the environment" to support the planned auth, hence VPN is one of solution

agree it is confusing. My reasons : It says "You have a hybrid configuration of Azure Active Directory (Azure AD)" which suggests that AD Connect is in place , but it isnt clear plus doesnt mention what configuration it has (Hash Synch, Pass through, Federated etc). Creating a site to site VPN will simply just enabled connectivty between the on premise network and the HDInsight cluster but not fulfil the authentifacation via on premises AD. So without exact knowledge of the configuration of the Hybrid AD , any AD connect etc it is impossible to say for sure that would work. You could take it further and say it is impossible to know as you dont know the config of the HD cluster, any NSGs etc. I always find this ambiguous questions a bit annoying if I have the knowledge to answer them but the details are too blurry.

Answer: B, No Reason: While a site-to-site VPN is part of the solution, it's not sufficient alone. You also need to configure Azure AD Domain Services (AD DS) for HDInsight to enable authentication using on-premises AD credentials. Hint: The VPN connection alone doesn't enable authentication. AD DS is an avaliable answer. Reference: https://learn.microsoft.com/en-us/azure/hdinsight/domain-joined/apache-domain-joined-introduction

The solution does not meet the goal because HDInsight ESP requires Azure AD DS, not direct on-premises AD integration. A site-to-site VPN alone is insufficient.

Yes, creating a site-to-site VPN between the virtual network and the on-premises network is part of the solution and meets the goal for allowing users to authenticate to the Azure HDInsight cluster using their on-premises Active Directory credentials. For hybrid authentication to Azure HDInsight, the site-to-site VPN enables secure communication between Azure and the on-premises environment. This allows the HDInsight cluster to access the on-premises Active Directory for user authentication. However, keep in mind that a site-to-site VPN alone is not sufficient; you will also need to ensure that: Active Directory Domain Services (AD DS) is accessible over the VPN connection. Azure HDInsight is configured to use this AD DS for Kerberos authentication.

A. Yes Creating a site-to-site VPN between the virtual network and the on-premises network would indeed meet the goal. This setup would allow the Azure HDInsight cluster on the virtual network to communicate with the on-premises network, thereby enabling users to authenticate to the cluster using their on-premises Active Directory credentials. The option “No” would imply that creating a site-to-site VPN between the virtual network and the on-premises network would not allow users to authenticate to the Azure HDInsight cluster using their on-premises Active Directory credentials. However, this is not the case.A site-to-site VPN allows secure communication between resources in a virtual network and an on-premises location over the public internet. It essentially extends your on-premises network to the cloud.

Answer: B Explanation: AI: Creating a site-to-site VPN between the virtual network and the on-premises network will establish a secure connection between the two networks, but it alone does not enable users to authenticate to the Azure HDInsight cluster using their on-premises Active Directory credentials. To support the planned authentication, you need to use Azure AD Domain Services to synchronize on- premises Active Directory with Azure AD. This synchronization will allow users to authenticate to the Azure HDInsight cluster using their on-premises Active Directory credentials. Therefore, the given solution alone does not meet the goal.

NO. Creating a site-to-site VPN between the virtual network and the on-premises network is not sufficient to allow users to authenticate to the Azure HDInsight cluster using their on-premises Active Directory credentials. Azure HDInsight supports integration with Azure AD and does not rely on a site-to-site VPN for integration with on-premises Active Directory. To enable user authentication with on-premises Active Directory credentials to your Azure HDInsight cluster, you must configure Azure Active Directory Domain Integration with Azure HDInsight. This involves configuring Azure AD Connect or Azure AD DS to extend Azure AD authentication to your on-premises environment. Therefore, creating a site-to-site VPN is not the appropriate solution for this scenario. Instead, you must configure Azure Active Directory Domain Integration as part of the solution.

Answer is No, creating a site-to-site VPN between the virtual network and the on-premises network alone does not meet the goal of allowing users to authenticate to the Azure HDInsight cluster using their on-premises Active Directory credentials. To achieve this goal, you should implement Azure AD Domain Services (Azure AD DS) or Azure AD Connect with Pass-Through Authentication (PTA) and Seamless Single Sign-On (SSO). These solutions enable users to use their on-premises Active Directory credentials to authenticate to Azure resources, including Azure HDInsight clusters.

Configuring Azure AD DS in your Azure AD tenant, not just creating a site-to-site VPN.

A is correct answer.

Ok I think I have figured out these 2 HDInsight questions. Either we need a VPN to on-prem AD to perform the authentication or we need Azure AD DS synced with Azure AD Connect (aka "a hybrid configuration"). Here is the other version of the question: https://www.examtopics.com/discussions/microsoft/view/3791-exam-az-500-topic-2-question-3-discussion/ My answer: Go with Azure AD DS as being the "Yes" variant on this series of questions, thus making this answer "No." Proof: https://learn.microsoft.com/en-us/azure/hdinsight/domain-joined/hdinsight-security-overview#authentication ^ This article discusses Enterprise Security Packages, but that seems to be the only method to connect Hadoop/Apache on which HDInsights is based to Active Directory (both on-prem and Azure AD DS).

No, creating a site-to-site VPN between the virtual network and the on-premises network does not meet the goal of configuring the environment to support user authentication to the Azure HDInsight cluster with on-premises Active Directory credentials. To enable authentication with on-premises Active Directory credentials, you need to configure Azure AD Domain Services. Azure AD Domain Services allows you to integrate your on-premises Active Directory environment with Azure AD. This integration enables users to authenticate using their on-premises credentials to access Azure resources such as the Azure HDInsight cluster. Creating a site-to-site VPN establishes a secure connection between the on-premises network and the Azure virtual network, allowing communication between the two environments. While it is necessary for hybrid connectivity, it does not directly enable authentication with on-premises Active Directory credentials for Azure resources. Therefore, the correct solution would involve configuring Azure AD Domain Services, not creating a site-to-site VPN.

B is correct

B. No is valid answer
