Wait, are you sure about that? I thought JournalNode was involved too.

I thought the Primary NameNode was more about data management, so I'm not confident about that option.

I’m leaning towards option A, but I might be mixing it up with another question about HDFS components.

I remember practicing a question about NameNode roles, and I feel like the standby NameNode was definitely involved.

I've got this! The Zkfc (ZooKeeper Failover Controller) and the standby NameNode are responsible for the active/standby management, and the primary NameNode works with the JournalNode to merge the metadata files.

Okay, I know the NameNode is responsible for managing the HDFS metadata, and there's an active and standby NameNode for high availability. I think the key is identifying which modules handle that functionality.

This seems like a straightforward question about HDFS NameNode management. I'll need to recall the roles of the different HDFS components to answer this.

Hmm, this looks like a tricky one. I'll need to carefully read through the options and think about the business partner data model in SAP MDG.

Hmm, I'm a bit confused on this one. The options seem to cover different aspects of the architecture process, but I'm not sure which one specifically describes the purpose of a Compliance Assessment. I'll have to think this through carefully.

Viewing business vision through business architecture kind of makes sense, but I'm worried I might mix it up with how to align IT strategies.
