AZ-305 Question 207
Select 2Contoso is planning to migrate a line-of-business application from on-premises to Azure. The application relies on a SQL Server 2012 database and a front-end web application running on Windows Server 2008 R2, both hosted on virtual machines. In addition, the environment depends on shared file servers storing large volumes of data. You have been tasked with performing a detailed assessment of the on-premises environment to ensure a smooth migration. Which two actions should you prioritize to accurately evaluate the servers, data, and applications for Azure readiness?
- A
Deploy Azure Migrate’s discovery appliance to gather detailed performance and dependency data from on-premises servers.
- B
Immediately upgrade all servers to the latest OS versions before performing any discovery or assessment.
- C
Inventory data usage patterns and plan for storage requirements in Azure, especially for large data volumes.
- D
Configure an App Service plan in Azure before analyzing the performance metrics of the existing environment.
Show answer and explanation
Correct answers: A, C
Explanation
Prioritizing an accurate inventory of server configurations, usage patterns, and dependencies is essential before migrating to Azure. Tools like Azure Migrate’s discovery appliance provide holistic insights into performance and compatibility. Additionally, understanding data storage requirements is crucial, especially for large data volumes moving to cloud-based storage. For more information, see Microsoft’s documentation on Azure Migrate best practices at https://docs.microsoft.com/azure/migrate/.
- A. Correct.
This is correct. Azure Migrate’s discovery appliance can collect crucial information such as CPU utilization, memory usage, disk I/O, and application dependencies. This data is essential for an accurate migration assessment and helps you plan resource sizing and compatibility in Azure.
- B. Incorrect.
This is incorrect. While eventually upgrading or modernizing the operating system may be necessary, it is generally best practice to perform discovery and assessments with the environment as-is to gather accurate performance baselines and dependencies. Premature OS upgrades can obscure real-world resource usage patterns.
- C. Correct.
This is correct. Understanding and documenting how data is used, accessed, and stored informs the choice of Azure storage services and migration structures. Accurate inventorying of data volumes, growth trends, and usage patterns is crucial in planning a successful migration strategy.
- D. Incorrect.
This is incorrect. It’s advisable to measure on-premises performance first. Setting up Azure infrastructure like an App Service plan without baseline data may lead to misconfiguration, wasted resources, or performance bottlenecks that could have been identified via proper discovery and assessment.
