Q1Domain Verified
In the context of the DDS Protocol Fundamentals Course, what is the primary mechanism by which DDS ensures data consistency and reliability across distributed participants, particularly when dealing with transient data?
A peer-to-peer communication model where participants directly exchange data using publish-subscribe semantics, managed by Quality of Service (QoS) policies.
A centralized message broker that serializes and routes all data.
A distributed ledger technology (blockchain) to record all data transactions.
A polling mechanism where each participant periodically queries others for updates.
Q2Domain Verified
A DDS application requires that a subscriber must receive all data samples published by a data writer, even if the subscriber joins the network after the data has been published. Which Durability QoS kind, as taught in the DDS Protocol Fundamentals Course, is most appropriate for this scenario?
TRANSIENT
PERSISTENT
VOLATILE
TRANSIENT_LOCAL
Q3Domain Verified
Consider a scenario where a DDS application has multiple DataWriters publishing to the same topic from different sources. To ensure that only one DataWriter is considered the "master" or authoritative source for a given data instance at any time, which DDS mechanism, covered in the fundamentals course, is employed?
