350-601 Storage Network Practice Question
A storage engineer is configuring replication between two data centers. The distance is 500 km with a round-trip latency of 10 ms. The application requires zero data loss in the event of a primary site failure. Which replication method should be chosen?
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
✓
Synchronous replication
Synchronous replication ensures zero data loss (RPO=0) as writes are acknowledged only after being committed on both sites. However, it is sensitive to latency; with 10 ms RTT, performance may degrade but it meets the requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Synchronous replication
Why this is correct
Synchronous replication provides zero data loss, but performance may suffer due to latency.
- ✗
Snapshot-based replication
Why it's wrong here
Snapshots are point-in-time and may lose data between snapshots.
- ✗
Asynchronous replication
Why it's wrong here
Asynchronous replication may lose some data if the primary fails before transfer.
- ✗
RAID-10 mirroring
Why it's wrong here
RAID-10 provides local redundancy, not remote replication.
