SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a large-scale Hadoop cluster to Amazon EMR. The migration plan includes moving data from HDFS to Amazon S3. The company wants to minimize costs and ensure data durability. Which approach should the company use?
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
✓
Use Apache DistCp to copy data from HDFS to S3.
B is correct because DistCp is designed for efficient HDFS-to-S3 transfers, and S3's 99.999999999% durability meets requirements. A is wrong because VPN and rsync are not optimized for large-scale data transfer to S3. C is wrong because Snowball Edge adds latency and is not necessary for data already in the cluster. D is wrong because AWS DMS is for databases, not file systems.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set up a VPN connection and use rsync to copy data to S3.
Why it's wrong here
rsync is not optimized for S3; DistCp is better.
- ✓
Use Apache DistCp to copy data from HDFS to S3.
Why this is correct
DistCp is the standard tool for copying between HDFS and S3.
- ✗
Use AWS Snowball Edge to physically transfer data from the cluster.
Why it's wrong here
Snowball is useful for large data but unnecessary if network bandwidth is sufficient.
- ✗
Use AWS Database Migration Service (DMS) to migrate the data to S3.
Why it's wrong here
DMS is for database migration, not file systems.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
