Final answer:
Availability zones are used in cloud computing to replicate resources across multiple physical locations, providing fault tolerance and high availability.
Step-by-step explanation:
Availability zones are used in cloud computing to ensure the availability and reliability of applications and data. They are a way to replicate resources across multiple physical locations within a cloud provider's infrastructure. This helps to protect against failures and disasters by providing redundancy and enabling quick recovery.
For example, in a cloud provider like Amazon Web Services (AWS), availability zones are separate data centers within a region. By deploying resources across multiple availability zones, data and applications are replicated, providing fault tolerance and ensuring high availability.
Therefore, the statement is TRUE.
