To ensure that only application servers from the source subnet 10.79.1.0/24 can access the SQL databases running on the NC2 cluster in the subnet 10.78.1.0/24, the administrator can take the following actions:
* Option A: Create a custom Security Group with the following rules:
* Key = tag:nutanix:clusters
* Key = tag:nutanix:clusters:external and value = the clusters ' UUID
* Key = tag:nutanix:clusters:external and value = 10.78.1.0/24
* Option D: Create a custom Security Group with the following:
* Key = nutanix:clusters
* Key = nutanix:clusters:external and value = the clusters ' UUID
* Key = nutanix:clusters:external and value = 10.79.1.0/24
These actions help create security rules that restrict access to the databases only from the specified source subnet, ensuring secure and controlled access.
