Practice question 367 of 400 · hard

Choose the single best answer.

  1. A.The source may lack accepted target writes, so rollback requires data reconciliation
  2. B.DNS can never be changed during a migration
  3. C.Performance issues always require deletion of the target data
  4. D.Every online migration provides automatic reverse replication
Show the answer and explanation

✓ Correct answer

  • The source may lack accepted target writes, so rollback requires data reconciliation

New target writes must be retained or reconciled before returning traffic to the source. DNS changes are possible but do not synchronize state; reverse replication is not universal; deleting data is not a valid blanket response. Source guide: PDF page(s) 63.
