Hi Sanaa, in KRaft mode there is the role of "observer" which is typically taken by brokers as part of the data plane. The broker/observer can discover which node is the leader/active controller and fetches the metadata from it (as the "followers" in the KRaft quorum), but cannot vote and cannot become leader. AFAIK it's allowing to change its role at some point if needed to be also a controller or anyway taking part at the quorum by also having the metadata topic already replicated.
