Read the first 7 AWS Migration & Hybrid Cloud flashcards as text

  1. A company running Microsoft SQL Server on-premises wants to migrate to AWS with the least schema and code changes possible. Which target is MOST appropriate?

    Answer: Amazon RDS for SQL Server

    Amazon RDS for SQL Server provides a fully managed SQL Server environment, minimizing schema and application changes compared to migrating to a different database engine.

  2. AWS Direct Connect supports which type of virtual interfaces (VIFs) for connecting to VPCs across multiple AWS accounts?

    Answer: Transit VIF

    A Transit VIF connects a Direct Connect connection to an AWS Transit Gateway, enabling connectivity to multiple VPCs and accounts through a single interface.

  3. During a migration using AWS DMS, the replication instance runs out of storage. What is the recommended remediation?

    Answer: Modify the replication instance to increase its allocated storage without stopping replication

    AWS DMS allows you to modify a replication instance's allocated storage online, and the change takes effect without requiring task interruption in most cases.

  4. A company wants to use AWS Outposts to extend AWS infrastructure into its on-premises data center. Which statement about Outposts is TRUE?

    Answer: Outposts delivers AWS compute and storage to on-premises locations and is managed by AWS

    AWS Outposts is fully managed by AWS, delivering native AWS services (EC2, EBS, RDS, EKS, etc.) to customer on-premises locations with AWS-owned hardware.

  5. Which AWS service helps assess on-premises server utilization and dependency mapping to plan a migration, without requiring agents on every server?

    Answer: AWS Application Discovery Service with agentless discovery via the Discovery Connector

    The AWS Application Discovery Service Discovery Connector is an agentless VMware appliance that collects VM metadata and performance data without installing agents on each server.

  6. A company is using AWS Transit Gateway to connect multiple VPCs and an on-premises network via Direct Connect. They want to prevent VPCs from communicating with each other while still allowing all VPCs to reach on-premises. How is this achieved?

    Answer: Use Transit Gateway route tables with isolated routing — attach VPCs to an isolated route table that only propagates the on-premises route

    Transit Gateway supports segmented routing via multiple route tables; placing VPCs in an isolated route table that only has the on-premises prefix prevents VPC-to-VPC traffic while allowing on-premises connectivity.

  7. When using AWS Storage Gateway in Tape Gateway mode, where are virtual tape archives stored after they are ejected from the virtual tape library (VTL)?

    Answer: Amazon S3 Glacier or Glacier Deep Archive

    Ejected virtual tapes move to Amazon S3 Glacier or Glacier Deep Archive (the virtual tape shelf), providing low-cost, durable long-term storage matching physical tape economics.
