To answer this question, we need to understand the concept of node configuration in Datastage 8.5.
Datastage is an ETL (Extract, Transform, and Load) tool used for data integration and data transformation tasks. It enables users to design and execute workflows, known as jobs, that extract data from multiple sources, transform it according to business rules, and load it into target systems.
In Datastage, a node represents a physical or virtual server where Datastage components can be installed and executed. Nodes are used to distribute the workload of a job across multiple servers, improving performance and scalability.
The maximum number of nodes that can be configured in Datastage 8.5 is 8 (Option C). This means that you can install and configure Datastage components on up to 8 servers to distribute the workload of a job.
Option A (10) and Option B (6) are incorrect because they do not represent the maximum number of nodes that can be configured in Datastage 8.5.
Option D (infinity) is incorrect because there is a limit to the number of nodes that can be configured in Datastage 8.5, which is 8.
Therefore, the correct answer is C.
