AZ-801 Question #9: Real Exam Question with Answer & Explanation

Question

You are planning the migration of APP3 and APP4 to support the Azure migration plan. What should you do on Cluster1 and in Azure before you perform the migration? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Explanation

This question tests knowledge of the pre-migration preparation steps required both on an on-premises cluster and in Azure before migrating applications using Azure Migrate or Azure Site Recovery. Both sides of the migration pipeline must be prepared before replication or cutover begins.

Approach. On Cluster1 (on-premises), you must install the Azure Migrate appliance or the Azure Site Recovery (ASR) Mobility Service agent on the source machines hosting APP3 and APP4, and ensure discovery/assessment has been completed so dependencies and sizing are understood. In Azure, you must pre-create the required target infrastructure - this includes an Azure Migrate project or a Recovery Services vault (for ASR), a target Virtual Network, a target Resource Group, and a cache/replication Storage Account in the target region. These steps must all be completed before initiating replication, because replication requires both an agent on the source and a configured destination to receive the replicated data.

Concept tested. Azure migration pre-requisites using Azure Migrate or Azure Site Recovery - specifically the dual-sided preparation required: deploying the replication agent/appliance on the source cluster AND provisioning the target Azure infrastructure (vault, VNet, storage account, resource group) before migration replication can begin.
