Which two cmdlets should you run?

Your company has two data centers in Berlin and one data center in Toronto. Each data center contains two Microsoft Exchange Server 2019 servers.

You have a database availability group (DAG) that contains all the Exchange servers. Each server contains a copy of all the mailbox databases.
