PAS-C01 Migration Practice Question
A company is migrating a large SAP Business Warehouse (BW) system to AWS. The system uses SAP HANA as the database. The migration plan involves using SAP HANA System Replication (HSR) for near-zero downtime. During the initial synchronization, the network bandwidth is limited to 1 Gbps. The source database is 5 TB. How long will the initial synchronization approximately take, assuming no other bottlenecks?
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
✓
Approximately 12 hours
5 TB = 5,000 GB = 40,000 Gb (since 1 GB = 8 Gb). At 1 Gbps, time = 40,000 seconds ≈ 11.1 hours. This simple calculation ignores overhead, but among the options, 12 hours is the closest. The other options are unrealistic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Approximately 2 hours
Why it's wrong here
Too short; would require much higher bandwidth.
- ✗
Approximately 6 hours
Why it's wrong here
Still too short for 5 TB at 1 Gbps.
- ✓
Approximately 12 hours
Why this is correct
5 TB at 1 Gbps gives about 11.1 hours; 12 hours is a reasonable estimate including overhead.
- ✗
Approximately 24 hours
Why it's wrong here
Double the expected time; unless there are other bottlenecks.
