- Answer: True.
Explanation: Azure provides services like Azure portal, Azure CLI, Power Shell etc. to configure service endpoints on subnets.
Single select: Which of the following is not a requirement for Azure Service Endpoints?
- A) Virtual Network
- B) Subnet
- C) Public IP
- D) Storage Account
Answer: C) Public IP
Explanation: Azure Service Endpoints do not require a public IP. They enable private and secure connectivity to Azure services.
Multiple select: Azure Service Endpoints support which Azure services?
- A) Azure Cosmos DB
- B) Azure Service Bus
- C) Azure SQL Database
- D) Azure Machine Learning
Answer: A) Azure Cosmos DB, B) Azure Service Bus, and C) Azure SQL Database.
Explanation: Azure Service Endpoints currently support Azure Cosmos DB, Azure SQL Database, and several other services, but not Azure Machine Learning.
True or False: Azure Service Endpoints extend your virtual network private address space and the identity of your virtual network to the service over a direct connection.
- Answer: True.
Explanation: Service endpoints extend your virtual network private address to Azure services over Microsoft’s backbone network.
Single select: Which Azure CLI command is used to create a service endpoint?
- A) az network vnet create
- B) az network vnet service-endpoint create
- C) az network vnet peering create
- D) az network vnet subnet create
Answer: B) az network vnet service-endpoint create
Explanation: az network vnet service-endpoint create is the correct command to create service endpoints in Azure CLI.
Multiple select: What benefits do Azure service endpoints offer?
- A) Improved security
- B) Reduced latency
- C) Access to all Azure regions
- D) None of these
Answer: A) Improved security, B) Reduced latency.
Explanation: Service endpoints provide improved security by allowing access to only your VNet traffic. They also provide route optimization which leads to reduced latency.
True or False: Azure service endpoints require an internet-facing endpoint.
- Answer: False.
Explanation: Azure service endpoints don’t require an internet-facing endpoint. Traffic between your virtual network and the service travels over the Microsoft backbone network, eliminating exposure from the public internet.
Single select: In which scenario would you use Azure service endpoints?
- A) To connect your on-premises network to Azure services.
- B) To securely expose an application to the internet.
- C) To secure traffic between your virtual network and Azure services.
- D) To create a virtual network peering connection.
Answer: C) To secure traffic between your virtual network and Azure services.
Explanation: Azure service endpoints are primarily used to secure traffic between your virtual network and Azure services over the Microsoft backbone network.
True or False: You can configure service endpoints on subnets to improve connectivity to other virtual networks.
- Answer: False.
Explanation: Service endpoints are used to secure traffic between your virtual network and Azure services, not to improve connectivity to other virtual networks.
Single Select: What is the purpose of Azure service endpoints in the context of a subnet?
- A) Extend on-premises networks.
- B) Access Azure services over public internet.
- C) Connect different subnets.
- D) Extend the private address space of the subnet to Azure service.
Answer: D) Extend the private address space of the subnet to Azure service.
Explanation: The role of service endpoints is to extend the private address space of the subnet to Azure services on the Microsoft cloud network, thereby improving security and connectivity.
Interview Questions
What is a service endpoint in Azure?
A service endpoint in Azure is a termination of a route in Azure, where Azure service is available. It helps to secure Azure service resources to your virtual network by eliminating all Internet-based access.
What is the main purpose of configuring service endpoints on a subnet?
Configuring service endpoints on a subnet allows you to isolate your network traffic from the rest of the Azure network, enabling you to create policies and route traffic through secure channels.
How do you enable a service endpoint on a subnet?
To enable a service endpoint on a subnet, you must navigate to the “subnets” page in the Azure portal, select the subnet you want to modify, and then choose the service you want to enable the endpoint for.
What protocol is used for service endpoints in Azure?
The protocol used for service endpoints in Azure is TCP only. UDP is not supported.
Is there any additional charge for using service endpoints in Azure?
There is no additional charge for using service endpoints in Azure.
What services can be configured for service endpoints in a virtual network?
The services that can be configured for service endpoints in a virtual network include Azure Storage, Azure SQL Database, and Azure Cosmos DB.
How do you remove a service endpoint from a subnet?
You can remove a service endpoint from a subnet by navigating to the “subnets” page, selecting the subnet from which you want to remove the endpoint, and then deselecting the endpoint.
Can service endpoints be used in conjunction with network security groups?
Yes, service endpoints can be used in conjunction with network security groups.
Can you restrict access to a storage account to a specific subnet?
Yes, you can restrict access to a storage account to a specific subnet by enabling a service endpoint on the subnet and configuring the networking settings of the storage account.
What happens if a virtual network service endpoint is deleted?
If a virtual network service endpoint is deleted, all policies that rely on it will stop working. It will result in a loss of access to the resources protected by those policies.
Can you apply a service endpoint to an existing subnet?
Yes, you can apply a service endpoint to an existing subnet.
Can I use Virtual Network Service Endpoints with Azure Key Vault?
Yes, you can use Virtual Network Service Endpoints with Azure Key Vault to secure and restrict your key vault’s access to your virtual network.
Is it possible to configure more than one service endpoint on a single subnet?
Yes, it is possible to configure multiple service endpoints on a single subnet.
Is it possible to enable service endpoints for Azure Kubernetes Services (AKS) clusters?
No, as of now, Azure Kubernetes Services (AKS) clusters do not support service endpoints.
How do service endpoints in Azure enhance security?
Service endpoints in Azure enhance security by providing direct network routing between your network and the Azure service over Microsoft’s backbone network, negating all Internet-based access to the service from your network.
