Which of the following should be considered to ensure the availability of data that is accessed across multiple sites? (Choose two.)

Geo-redundancy and backup are two methods that can ensure the availability of data that is

accessed across multiple sites. Geo-redundancy is the practice of storing data in more than one

geographic location, such as different regions, countries, or continents. This can improve the data

availability by reducing the impact of natural disasters, network failures, or malicious attacks that

may affect one site. Geo-redundancy can also improve the data performance by allowing users to

access the data from the nearest or fastest site. Backup is the process of creating and storing copies

of data that can be used to restore the original data in case of data loss, corruption, or deletion.

Backup can ensure the data availability by providing a way to recover the data from a previous state,

such as before a hardware failure, software error, or human error. Backup can also protect the data

from accidental or intentional modifications that may compromise its integrity or security.

Geo-redundancy and backup are different from other options, such as auto-scaling, provisioning,

locality, and zones. Auto-scaling is the ability of a cloud service to automatically adjust the amount of

resources allocated to a workload based on the demand or usage. Provisioning is the process of

allocating and configuring the resources needed to run a cloud service or application. Locality is the

principle of storing data close to where it is used, such as in the same region, country, or jurisdiction.

Zones are logical or physical subdivisions of a cloud region that provide isolation and redundancy for

the cloud resources. While these options may also affect the data availability, they do not directly

address the data access across multiple sites, which is the focus of the

question. Reference: Extending a Datastore Across Two Sites with Stretched Clusters, SQL Server
