SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a containerized application from on-premises Kubernetes to Amazon EKS. The application requires persistent storage with high IOPS and must be accessible by multiple pods across different Availability Zones. Which storage solution should be used?
⚠ Common exam trap
The trap here is assuming that Amazon EBS Multi-Attach can be used across Availability Zones, but it is limited to a single AZ and cannot satisfy cross-AZ sharing.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon EFS with provisioned throughput.
Amazon EFS provides a shared, POSIX-compliant file system that can be mounted by multiple pods across Availability Zones. With provisioned throughput, EFS can deliver high IOPS independent of storage capacity, meeting the performance requirement. Other options are either not shared across AZs, not durable, or not suitable for high-performance file storage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon S3 mounted as a file system using s3fs.
Why it's wrong here
S3 is object storage and is not designed for high-IOPS file system access. Using s3fs can introduce latency and is not suitable for persistent storage requiring high IOPS and POSIX compliance. It also lacks the performance characteristics needed for containerized applications.
- ✗
Amazon FSx for Lustre with a scratch file system.
Why it's wrong here
FSx for Lustre scratch file systems do not provide replication and are not highly durable; they are designed for temporary storage and high-performance computing. They also may not be accessible across multiple Availability Zones by default, depending on deployment type.
- ✗
Amazon EBS with io2 Block Express volumes.
Why it's wrong here
Amazon EBS volumes are tied to a single Availability Zone and can only be attached to one EC2 instance at a time (except for Multi-Attach io1/io2 which is limited to a single AZ). They cannot be shared across multiple pods in different Availability Zones, so they fail the requirement.
- ✓
Amazon EFS with provisioned throughput.
Why this is correct
Amazon EFS is a shared file system that can be mounted by multiple pods across different Availability Zones within a region. Provisioned throughput mode allows specifying throughput independently of storage size, providing the high IOPS required for the application.
