        Examples:
            This example creates a client using the local system's default D-Wave 
            Cloud Client configuration file, which is configured to access an 
            Advantage QPU, and tests a simple :term:`Ising` model for two target 
            minor embeddings (that is, representations of the model's graph by 
            coupled qubits on the QPU's sparsely connected graph), where only 
            the second is valid.
