Q10 — AWS DOP-C02 Ch.1

Question 10 of 100 | ← Chapter 1

A company is migrating its software development team from an on-premises data center to a hybrid environment. The new environment will span four AWS Regions, enabling developers to use the geographically closest Region. All development teams use a shared set of Linux applications. On-premises data centers store these applications on a network-attached storage (NAS) device. Developers run VMs locally, and the shared volume is updated weekly.

• A. Create an Amazon S3 File Gateway in the on-premises data center. Create S3 buckets in each Region. Set up a cron job to copy data from the on-premises storage device to the S3 File Gateway. Enable S3 Cross-Region Replication (CRR) from the gateway bucket to buckets in each Region.
• B. Create an Amazon FSx File Gateway in one Region. Create file servers in Amazon FSx for Windows File Server for each Region. Set up a cron job to copy data from the on-premises storage device to the FSx File Gateway.
• C. Create multi-AZ Amazon FSx for NetApp ONTAP with volumes and instances for each Region. Configure a scheduled SnapMirror relationship between the on-premises storage device and FSx, consumable by on-demand instances. ✓
• D. Create an Amazon Elastic File System (Amazon EFS) file system in each Region. Deploy an AWS DataSync agent in the on-premises data center. Schedule daily DataSync tasks to replicate data to Amazon EFS.

Correct Answer: C. Create multi-AZ Amazon FSx for NetApp ONTAP with volumes and instances for each Region. Configure a scheduled SnapMirror relationship between the on-premises storage device and FSx, consumable by on-demand instances.

Explanation

This question evaluates selection of cross-Region data synchronization solutions in hybrid cloud environments, emphasizing AWS storage service characteristics and replication mechanisms. Key requirements include read-only data synchronization across multiple Regions, independence from on-premises storage, and guaranteed freshness. Correct solution C uses Amazon FSx for NetApp ONTAP with multi-AZ deployment for high availability and scheduled SnapMirror for asynchronous, incremental replication from on-premises to cloud—naturally aligned with weekly update frequency and fully decoupling from local storage dependency. Other options rely on manual scheduling (A/D cron/DataSync), platform incompatibility (B’s Windows File Server for Linux apps), or insufficient timeliness (D’s daily sync), failing to meet real-time consistency and architectural independence requirements.
