Which statement regarding Delta synchronization is NOT TRUE?

The statement that is not true regarding Delta synchronization is the one that mentions using UDP Multicast or Broadcast on port 8116. In reality, Delta synchronization utilizes UDP Multicast or Broadcast on port 8161.

Delta synchronization is a mechanism that optimizes the way changes or updates are communicated between cluster members. Rather than sending all the data, which would happen during a full synchronization, Delta synchronization only sends the changes that have occurred in the security policy or kernel tables. This approach significantly reduces the amount of data transmitted and accelerates the synchronization process, making it quicker than a full sync.

By specifically relying on port 8161 for Delta synchronization, the data packets are properly routed and received by the intended cluster members, maintaining an efficient and effective communication channel. Understanding the correct port is essential for successful configuration and troubleshooting in a cluster environment.
