4
Explain the Azure Resource Hierarchy
Reference answer
The Azure resource hierarchy is the structure used to organize and manage resources effectively across an organization. It consists of four levels of scope: - Management Groups: These are containers that help manage access, policy, and compliance for multiple subscriptions. All subscriptions within a management group automatically inherit the conditions applied to the management group. - Subscriptions: These are logical containers that serve as units of management and billing. A user can have multiple subscriptions (e.g., Development, Production) to separate costs and access limits. - Resource Groups: A logical container that holds related resources for an Azure solution. A resource group includes those resources that you want to manage as a group (e.g., a web app, its database, and its storage account). - Resources: The individual instances of services created in the cloud, such as Virtual Machines, App Services, or SQL Databases.
5
How would you leverage Azure services to implement a serverless architecture?

If you are given the task of migrating an old on-premise application to the cloud, how will you do it?
Reference answer
Answer: First of all, the application has to be properly assessed: - Which systems is it connected to (Dependencies)? - How much load does it bear (Performance)? - How much data is there and where is it stored? Then comes the "6 R's of Migration": - Rehost (Lift and Shift): Moving the application to the cloud as it is. No change in the code. - Replatform (Lift and Reshape): Using the benefits of the cloud by making slight changes. For example - using a cloud database. - Refactor (Re-architect): Rebuilding the application - for example with microservices or serverless architecture. - Repurchase (Drop and Shop): Drop the old system and buy a readymade SaaS solution. - Retain: If necessary, keep some part on-premise. - Retire: If an old system is no longer needed, remove it. What else to do: - First pick up a small, less-important app and test it (pilot project). - Do data migration in such a way that downtime is minimal. - Do cloud optimization after migration – so that performance, cost and security all three are better.
23

41
How do you ensure the interoperability of applications and systems in a complex environment?
Reference answer
To ensure the interoperability of applications and systems in a complex environment, a Microsoft Solution Architect should consider the following: - Use standardized protocols and formats: Using standardized protocols and formats such as REST, SOAP, and JSON can help ensure that systems can communicate with each other seamlessly. - Leverage API gateways: An API gateway can act as a central point for managing and routing requests between different systems. By implementing an API gateway, the Solution Architect can ensure that systems can communicate with each other, regardless of their underlying technology. - Adopt microservices architecture: A microservices architecture can help break down complex systems into smaller, more manageable services. This approach can help improve interoperability by enabling different services to be developed independently of each other. - Implement service-oriented architecture (SOA): SOA is an architectural style that emphasizes the use of loosely coupled services. By implementing SOA, a Solution Architect can create a system where services can communicate with each other seamlessly, even if they are developed using different technologies. - Use messaging queues: Messaging queues can be used to enable asynchronous communication between systems. This approach can help ensure that systems can communicate with each other, even if one system is temporarily unavailable. - Ensure data consistency: To ensure interoperability, the Solution Architect must ensure that all systems are using the same data model and that data is consistent across different systems.
42
Can you share an example of how you used data analytics in cloud solution architecture?
Reference answer
In one project, I used data analytics to optimize the performance of a cloud-based application. By analyzing usage patterns and traffic data, I identified bottlenecks and areas for improvement. This information informed my decisions on resource allocation, scaling strategies, and other optimizations, ultimately leading to a more efficient and cost-effective solution.

Perform schema and data migration with minimal downtime using DMS. Validate data integrity. Set up connectivity (VNet, hybrid connections). Optimize performance and implement backup/disaster recovery post-migration.
46
How do you design for scalability in cloud environments when faced with unpredictable traffic patterns?
Reference answer
"Unpredictable traffic requires both horizontal and vertical scaling strategies. And scalability is achieved through decoupling services, using auto-scaling, load balancing, and caching strategies. We tackled unpredictable traffic with a layered approach—SQS queues to absorb spikes, CloudFront caching for the front-end, and auto-scaling groups that actually learned from historical patterns. Database scaling was our biggest headache until we split read/write workloads across Aurora replicas. The proof came during Black Friday when we handled a 600% surge that would've flattened our old system."
47
What is Azure App Service?
Reference answer
- Azure App Service is a fully managed PaaS for developing web, mobile, and integration applications. It provides scalability, security, and reliability, allowing developers to focus on the application instead of managing infrastructure.
48
What if we already have resources in our landing zones and later assign an Azure Policy definition that includes them in its scope?
Reference answer
If you assign an Azure Policy definition to a scope that includes existing resources, Azure Policy will automatically evaluate those resources to determine if they comply with the newly assigned policy. Here's what happens step-by-step: 1. Initial Compliance Evaluation Once the policy is assigned, Azure Policy immediately assesses all resources within the scope (e.g., management group, subscription, or resource group) to see if they meet the policy criteria. Each resource is flagged as either compliant or non-compliant based on whether it adheres to the policy requirements. The Azure Policy dashboard displays a compliance report, giving you visibility into which resources comply, and which do not. 2. Handling Non-Compliant Resources For resources flagged as non-compliant, the next steps depend on the policy's effect type: Audit: Marks resources as non-compliant but doesn't enforce any change. This allows you to monitor compliance without affecting existing configurations. Deny: Blocks new resources or configuration changes that don't comply with the policy. However, it doesn't apply to existing resources, meaning those already in place will remain as-is but will still be flagged as non-compliant. DeployIfNotExists: For non-compliant resources, Azure Policy can automatically deploy missing configurations or settings. For example, if a policy requires diagnostic logging and a resource doesn't have it enabled, this effect can automatically enable it. Modify: Similar to DeployIfNotExists, but this effect modifies existing non-compliant resources to bring them into compliance. For instance, if a resource requires a specific tag, the Modify effect can add it. 3. Ongoing Monitoring Azure Policy continuously evaluates resources within the scope to detect new non-compliance issues. If configurations change and violate policy requirements, the policy will flag the resource as non-compliant again. You can set up alerts in Azure Policy to notify you whenever a resource falls out of compliance, enabling proactive management. 4. Remediation Tasks If there are existing non-compliant resources that require specific configuration changes, you can use remediation tasks within Azure Policy to correct them. Remediation tasks apply the DeployIfNotExists or Modify effects retroactively, updating non-compliant resources to meet policy standards. Remediation tasks are particularly useful for bringing older resources in line with new policies without manual reconfiguration.
49
Describe the concept of Virtual Private Cloud (VPC) in GCP and its benefits.
Reference answer
A VPC is a logically isolated network within GCP where you can launch resources like VMs and databases. Benefits include enhanced security through network segmentation, control over IP addressing, subnets, and firewall rules, and the ability to connect to on-premises networks via VPN or Cloud Interconnect.
50
How would you design for high availability and disaster recovery in an Azure environment?
Reference answer
Azure offers a variety of services and solutions for designing high availability and disaster recovery. For example, Azure Virtual Machines can distribute traffic across multiple servers to ensure high availability. Azure Site Recovery replicates workloads for quick recovery in case of a disaster. When designing for high availability and disaster recovery in an Azure environment, consider implementing data redundancy across different geographic regions, ensuring automatic failover mechanisms, and regularly testing disaster recovery plans to identify vulnerabilities. Additionally, integrate Azure Traffic Manager and Azure Load Balancer to distribute traffic across regions and avoid potential points of failure. By using these services, organizations can effectively plan for unforeseen events or outages.
51
What is Azure Network Watcher, and how does it help in troubleshooting?
Reference answer

It also supports serverless compute for auto-scaling based on demand.
53
How do you ensure the portability of applications and data in a multi-cloud environment?
Reference answer
To ensure the portability of applications and data in a multi-cloud environment, a Microsoft Solution Architect should consider the following: - Use containerization: Containerization allows applications to be packaged with all their dependencies, making them more portable across different environments. Solutions Architects can use tools like Docker and Kubernetes to deploy and manage containers across different clouds. - Implement cloud-agnostic architectures: Solutions Architects should design systems that are not tied to a specific cloud provider. This can be achieved by using open-source tools and technologies that work across multiple clouds. - Use cloud-native services: When designing solutions, Solutions Architects should consider using cloud-native services that are available across different clouds. For example, using services like AWS Lambda, Azure Functions, or Google Cloud Functions can make it easier to move applications between clouds. - Implement a data management strategy: To ensure data portability, Solutions Architects must consider how data is stored, accessed, and moved between different clouds. Solutions Architects should consider using open standards for data storage and integration, such as SQL and REST. - Implement a multi-cloud management platform: A multi-cloud management platform can provide a single interface to manage multiple clouds, making it easier to deploy and manage applications and data across different environments. - Ensure security and compliance: Solutions Architects must ensure that their solutions are secure and compliant across all the clouds they use. They should consider using cloud-native security tools, as well as tools that can provide compliance across multiple clouds.

A video sharing website uses an RDS MySQL database in one Availability Zone. Most website traffic is from users viewing videos. At times, those users complain about the speed of the application. Also, you need to make the application highly available across two regions. What should you do?
Reference answer
Create a read replica in a second region for the read traffic. The scenario in the question is actually the ideal use case for a read replica. By creating a read replica, the users who are only viewing videos (read-only traffic) can be directed to the replica, thereby reducing the load on the primary database. Read replicas can also be cross-region, which would fulfill the requirements in the question.
59
What is Windows Azure Scheduler?
Reference answer
Windows Azure Scheduler enables you to invoke activities, for example, calling HTTP/S endpoints or presenting a message on a storage queue on any schedule. With Scheduler, you make jobs in the cloud that dependably call services both inside and outside of Windows Azure and execute those jobs on-demand, on a routinely repeating schedule, or assign them for a future date.
60
Q4. You need to provide temporary access to Cosmos DB to your application, which component of Cosmos DB you will use?
Reference answer
If you want to provide other users temporary access to your Azure Cosmos DB account, you can do so by using the read-write and read access URLs. Read-Write – When you share the Read-Write URL with other users, they can view and modify the databases, collections, queries, and other resources associated with that specific account. Read – When you share the read-only URL with other users, they can view the databases, collections, queries, and other resources associated with that specific account. For example, if you want to share the results of a query with your teammates who do not have access to the Azure portal or your Azure Cosmos DB account, you can provide them with this URL.
61
In Azure Architect, how is the application created?
Reference answer
Creating an application in Azure involves using Azure App Service or Azure Kubernetes Service for web applications. For Azure App Service, you would navigate to the Azure portal, select "Create a resource," choose "Web App," and then provide necessary details like name, subscription, resource group, and publish settings. For containerized applications, you might use Azure Kubernetes Service by creating the Kubernetes cluster and deploying your containerized app to it. Both methods require selecting the right configuration, size, and region before deploying code through various supported methods (e.g., Git, Azure DevOps).
62

63
How would you implement a secure hybrid identity solution integrating on-premises Active Directory with Azure AD, ensuring single sign-on and conditional access policies?
Reference answer
Use Azure AD Connect to synchronize on-premises AD with Azure AD. Implement Azure AD Seamless Single Sign-On for SSO. Enable Multi-Factor Authentication (MFA) and configure Conditional Access policies based on user, location, and device compliance. Utilize Azure AD Pass-through Authentication or Federation Services for authentication, ensuring secure and seamless hybrid identity management.
64
Define application partitions in Azure Active Directory.
Reference answer
The application partitions are directory partitions that are copied to domain controllers and belong to the Azure Active Directory system. These domain controllers that are involved in the partitioning procedure keep a copy of the partition. Application partitions have the advantage of being able to be cloned to any individual domain controller, potentially leading to traffic reduction. Although domain directory partitions can transport their entire data to all the domains, application partitions in the domain area can only target one. This minimizes the need for application partitions and thereby increases their availability.

What do you understand about the "Availability Set"?
Reference answer
- Availability Set is nothing but a logical grouping of VMs (Virtual Machines) that allows Azure cloud to understand how the application was developed for providing availability and redundancy. - Each VM in the availability set is assigned 2 kinds of domains by Azure: - Fault Domain: These define the grouping of VMs that would share a common power source and common network switch. The VMs within availability sets are separated across up to 3 fault domains by default. This separation of VMs in fault domains helps our applications to be available by reducing impacts of network outages, power interruptions, and certain hardware failures. - Update Domain: These indicate the grouping of VMs and underlying hardware which are eligible to be rebooted at the same time. Only one update domain can be rebooted at a time, however, the order of reboot does not proceed in a sequential manner. Before the maintenance of another update domain, the previously rebooted domain is given a recovery time of 30 minutes to ensure that the domain is up. - Azure provides flexibility to configure up to 3 fault domains and 20 update domains for an availability set.

Consider a scenario where an application front end hosting is done on Azure but the customer needs the database hosting to be done on on-premise server due to security concerns. What are the ways to handle the connectivity in Azure for this scenario?
Reference answer
- Possibility 1: Azure VNET based "Point to Site" service can be a correct choice for this scenario of connecting one on-premise DB to an Azure-hosted app. "Point to Site" is valid for cases where the count of resources to be connected via VPN is very limited. - Possibility 2: In case there is a large number of resources for connection, then "Site to Site" or "Express routes" are the other options that could be considered. - There might be chances that using "Site to Site" might lead to network latency as VPN due to these work only via Internet (public infrastructure). In such cases, "Express Routes" are used as it provides dedicated leased line for overcoming latency issues. - Possibility 3: In case the customer is not willing to work via VNET, then Windows Communication Foundation (WCF) service can be developed and hosted on-premise which would have CRUD operations meant only for the database hosted on-premise. This works by means of using the "Service bus relay" option for developing communication between the Azure-hosted app to the WCF service for database access.
