Final answer:
Cluster versions for managed customers with premium support are supported for 3 years.
Step-by-step explanation:
The cluster versions for managed customers with premium support are typically supported for 3 years.
This means that during the first three years after a cluster version is released, it will receive updates, security patches, and technical support. After the three-year period, the cluster version may continue to operate, but it will no longer receive official support from the provider.
It's important for managed customers to upgrade to a supported cluster version within the specified timeframe to ensure they receive ongoing support and benefit from the latest features and security enhancements.
