An architect compares geo-redundant storage and geo-zone-redundant storage for a critical account. Both replicate to a paired secondary region. What is the primary difference between GRS and GZRS?
- AHow data is replicated within the account primary region Correct
- BWhether the secondary region copy is encrypted at all
- CWhether any secondary region copy is created at all
- DHow the secondary region replicates the copied account
Why A is correct: Correct. The docs state the primary difference between GRS and GZRS is how data is replicated in the primary region: GRS uses LRS and GZRS uses ZRS, while within the secondary region data is always replicated synchronously using LRS for both.
Why B is wrong: All redundancy options encrypt data in both regions, so encryption is not the difference.
Why C is wrong: Both GRS and GZRS create a secondary region copy, so this is not the difference.
Why D is wrong: Within the secondary region both options always replicate synchronously using LRS.
