The three main resiliency options for IBM Cloud Object Storage areCross Region, Regional, and Single Data Center.
Resiliency Options in IBM Cloud Object Storage:
Single Data Center: Stores data in one location, ideal for low-latency access and data residency requirements.
Regional (also known as Multizone): Stores data across multiple data centers within the same geographic region, providing higher availability and protection against data center failure.
Cross Region: Stores data across multiple geographic regions, offering the highest level of availability and disaster recovery capability.
References from IBM Cloud Professional Architect Materials:
As per IBM's documentation on Cloud Object Storage, these three options represent the primary resiliency models offered by IBM for their object storage service.
Other options are incorrect:
A. Cross Zone, Multizone, and RegionalandC. Cross Region, Cross Zone, and Single Data Centerdo not align with the actual resiliency models.
B. Single Data Center, Multizone, and Regionalis partially correct but lacks the "Cross Region" option.
