What destination versions are supported for a Multi-Version Cluster Upgrade?

The correct answer is B. R80.10 and later.

According to the Check Point documentation1, the Multi-Version Cluster Upgrade (MVC) is a new feature in R80.40 and higher that replaces the Connectivity Upgrade (CU) method. MVC allows you to upgrade a cluster to a newer version without a loss in connectivity and test the new version on some of the cluster members before you decide to upgrade the rest of the cluster members. The MVC feature supports the following destination versions2:

R80.10

R80.20

R80.30

R80.40

R81

R81.20

The other options are incorrect because they are either not supported by MVC or they are older than the source version (R80.40).
