SAP-C02 Question #711: Real Exam Question with Answer & Explanation
The correct answer is B: Deploy a new Amazon FSx for Lustre file system. Configure Bursting Throughput mode for the file. To provide a shared, high-throughput file system for Linux servers with burstable performance and cross-region disaster recovery, an Amazon FSx for Lustre file system with Bursting Throughput mode is recommended. Data can be linked to Amazon S3, enabling cross-region replication
Question
A company is deploying a new web-based application and needs a storage solution for the Linux application servers. The company wants to create a single location for updates to application data for all instances. The active dataset will be up to 100 GB in size. A solutions architect has determined that peak operations will occur for 3 hours daily and will require a total of 225 MiBps of read throughput. The solutions architect must design a Multi-AZ solution that makes a copy of the data available in another AWS Region for disaster recovery (DR). The DR copy has an RPO of less than 1 hour. Which solution will meet these requirements?
Options
- ADeploy a new Amazon Elastic File System (Amazon EFS) Multi-AZ file system. Configure the file
- BDeploy a new Amazon FSx for Lustre file system. Configure Bursting Throughput mode for the file
- CDeploy a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume with
- DDeploy an Amazon FSx for OpenZFS file system in both the production Region and the DR
Explanation
To provide a shared, high-throughput file system for Linux servers with burstable performance and cross-region disaster recovery, an Amazon FSx for Lustre file system with Bursting Throughput mode is recommended. Data can be linked to Amazon S3, enabling cross-region replication for a low Recovery Point Objective (RPO).
Common mistakes.
- A. Amazon EFS would require expensive Provisioned Throughput to meet the 225 MiBps requirement on a 100 GB file system, as its burst throughput based on size is insufficient.
- C. Amazon EBS is block storage attached to a single EC2 instance, not a shared file system that can be accessed by multiple application instances simultaneously.
- D. Amazon FSx for OpenZFS does not offer a specific Bursting Throughput mode that aligns with the cost-effective burst requirement for a 100 GB dataset as effectively as FSx for Lustre.
Concept tested. High-performance shared file system for Linux and DR strategy.
