Interview Questions
What is Azure Synapse Analytics?
Azure Synapse Analytics is a limitless analytics service that brings together enterprise data warehousing and Big Data analytics all in one place. It gives you the freedom to query data on your terms, using either serverless on-demand or provisioned resources.
What is Azure Cosmos DB?
Azure Cosmos DB is a globally distributed, multi-model database service for managing data at large scale with millisecond response times. It is designed for global applications, offering multiple well-defined consistency models, elastic scaling of throughput and storage, and automatic multi-region distribution.
What is Network Isolation in Azure?
Network Isolation in Azure refers to the concept of segregating or isolating different networks for data solutions within your Azure environment to enhance security and reduce the risk of data breach or compromise on resources.
How does network isolation work in Azure Synapse Analytics?
Azure Synapse Analytics allows users to create private endpoint which provides secure and private IP address in their Virtual Network (VNet), enabling them to connect their client applications within their VNet to Synapse SQL private link resources. The traffic between the VNet and Synapse SQL traverses over the Microsoft backbone network, eliminating exposure from the public internet.
How can you implement network isolation for Azure Cosmos DB?
Network isolation for Azure Cosmos DB can be implemented by using virtual network service endpoints. It secures your Azure Cosmos DB accounts to your virtual network (VNet), fully logging and auditing the data that is going in and out.
What are the benefits of network isolation in Azure Cosmos DB?
Network isolation in Azure Cosmos DB enhances security by extending your virtual network private address space. The outbound flows are kept private and secure as your data is not exposed to the public internet when connecting to your Azure Cosmos DB.
What does the VNet service endpoints do in Azure Cosmos DB?
The VNet service endpoints secure your Azure Cosmos DB account to your virtual network (VNet), ensuring that all outbound flows remain private to your VNet and subnet.
Can you provision a private endpoint for Azure Synapse Analytics?
Yes, Azure Synapse Analytics supports creating a private endpoint which provides a secure and private IP address in a Virtual Network (VNet). This enables connecting client applications within the VNet to Synapse SQL.
What is the importance of network isolation for data solutions in Azure?
Network isolation in Azure is essential as it enhances the security of resources by segregating or partitioning different networks, reducing the risk of data breaches or compromises on resources.
How does Azure Firewall protect Azure Synapse Analytics and Azure Cosmos DB?
Azure Firewall can be used to create network rules that allow or deny traffic to and from Azure Synapse Analytics or Azure Cosmos DB. It permits known IP addresses and blocks all other traffic to these resources, ensuring that only the desired traffic is permitted.
Can Azure Synapse Analytics be integrated with Azure Private Link?
Yes, Azure Synapse Analytics can be integrated with Azure Private Link. It provides a private address within a customer’s virtual network (VNet) and secures the data while in transit over the Microsoft backbone network.
How does Azure Private Link enhance security in Azure Synapse Analytics and Azure Cosmos DB?
Azure Private Link provides private connectivity from a virtual network to Azure Synapse Analytics or Azure Cosmos DB, eliminating exposure to the public internet. It simplifies the network configuration and enhances the security by reducing potential attack surfaces.
Can Azure Cosmos DB be configured with Azure Private Link?
Yes, Azure Cosmos DB can be configured with Azure Private Link. It provides a secure and scalable way to access Azure Cosmos DB over a private network connection.
