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

  1. A company is using AWS DataSync to migrate 500 TB of NFS data to Amazon S3. To maximize throughput, how should DataSync tasks be configured?

    Answer: Use multiple DataSync tasks running in parallel across different source directories

    Running multiple DataSync tasks in parallel across different source directories maximizes aggregate throughput and reduces total migration time.

  2. Which AWS service provides a fully managed, petabyte-scale data transport solution that uses secure, rugged devices to physically move data to AWS when network bandwidth is insufficient?

    Answer: AWS Snowball Edge

    AWS Snowball Edge is a physical device used to transfer petabyte-scale data when network transfer is impractical due to bandwidth or time constraints.

  3. A company wants to keep its on-premises Oracle database as the primary system while replicating changes to Amazon RDS in near real-time. Which AWS service is best suited for this ongoing replication?

    Answer: AWS Database Migration Service (DMS) with ongoing replication

    AWS DMS supports ongoing replication (CDC) that continuously streams changes from a source database to a target, enabling near real-time synchronization.

  4. An enterprise needs a dedicated, private connection between its on-premises data center and AWS with consistent network performance. Which solution meets this requirement?

    Answer: AWS Direct Connect

    AWS Direct Connect provides a dedicated, private network connection from on-premises to AWS, delivering consistent throughput and reduced latency compared to internet-based connections.

  5. Which AWS Migration Hub feature allows you to track the migration status of applications across multiple AWS migration tools from a single console?

    Answer: Migration Hub Orchestrator

    Migration Hub Orchestrator automates and coordinates multi-step migration workflows, tracking progress across tools like DMS, Application Migration Service, and others.

  6. A company is migrating VMs from VMware vSphere to AWS using Application Migration Service (MGN). What is the correct order of steps in the MGN replication lifecycle?

    Answer: Install agent → Continuous replication → Launch test instance → Cutover

    MGN follows the sequence: install the replication agent on the source server, allow continuous block-level replication, launch a test instance to validate, then perform the final cutover.

  7. A hybrid cloud architecture uses AWS Storage Gateway in File Gateway mode. What is a key characteristic of this configuration?

    Answer: It exposes an NFS/SMB interface on-premises while storing data durably in Amazon S3

    File Gateway presents NFS and SMB file shares to on-premises clients while transparently storing the data as objects in Amazon S3.
