350-601 Storage Network Practice Question
A storage administrator is configuring synchronous replication between two storage arrays over a Fibre Channel link. Which characteristic best describes synchronous replication?
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
✓
The write is acknowledged to the host only after data is written to both primary and secondary.
Synchronous replication writes data to both the primary and secondary storage before acknowledging the write to the host, ensuring zero data loss but increasing latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data is written to the primary and then asynchronously to the secondary, reducing latency.
Why it's wrong here
That describes asynchronous replication.
- ✓
The write is acknowledged to the host only after data is written to both primary and secondary.
Why this is correct
Synchronous replication ensures data is on both sides before acknowledgment.
- ✗
The secondary storage is used only for backup and is not actively updated.
Why it's wrong here
Synchronous replication continuously updates the secondary.
- ✗
Data is written to the primary and later replicated based on a schedule.
Why it's wrong here
That is periodic replication.
