I thought Redis was a database too, but not relational?

I feel like MongoDB and Redis are not relational, but I can't recall if HBase is considered one.

Ah, I see now. vMotion is used to migrate VMs during an upgrade, not for rolling back patches. I'll eliminate option B.

Okay, the key detail seems to be the address range of 172.16.0.0/16. I think I know how to apply that to determine the correct authentication scope.

This seems like a straightforward question about intellectual property. I'm pretty confident I know the answer, but I'll double-check my notes just to be sure.

Hold on, did someone just say 'relational databases'? I thought we were talking about how to relate to our databases on a personal level. Guess I misunderstood the assignment.

MongoDB and Redis are not relational databases, so I'll skip those. The rest look good to me.

I agree with Marjory. Those databases are designed to store and manage data in tables with relationships between them, making them relational databases.

I think Oracle, MySQL, PostgreSQL, MariaDB, and SQL Server are relational databases because they use structured query language (SQL) to manage and manipulate data.
