An IBM Cloud multizone region (MZR) is designed to enhance the availability, reliability, and resilience of cloud services. It consists of three or more separate, geographically dispersed zones within a single region, which are interconnected through high-speed and low-latency networks.

Multiple Zones for High Availability:In a multizone region, each zone represents a separate data center or availability zone with its own independent power, cooling, and networking. The multiple zones are interconnected, allowing for failover capabilities. If one zone experiences a failure, services can continue to operate in another zone within the same MZR, minimizing downtime and ensuring business continuity.

Resilience and Disaster Recovery:MZRs are specifically designed to offer a higher level of fault tolerance compared to single-zone regions. They provide geographic redundancywithin the same region, meaning that workloads can be replicated across different zones, thereby protecting against zone-level failures.

Interconnected Yet Independent:While the zones within an MZR are interconnected for data replication and low-latency communication, they are also physically and logically separated to prevent a single point of failure from affecting multiple zones.

Comparison with Other Options:

Option A is partially correct but does not fully describe an MZR.

Option B is incorrect because a failure in one zone does not affect all other zones.

Option C is incorrect as it does not specify that an MZR consists of multiple zones within the same geographical region.
