What are the minimum requirements to orchestrate this? (Choose Two)

A. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into A.

B. Link A, B and C using On Subject Ok triggers.

C. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into B.

D. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into C

Answer: B, D

Explanation:

To create a job consisting of two subjobs, A and B, and add a Joblet C with the intention of running it between A and B, you need to do the following steps:

Design subjob A by adding components and links to it in the Designer workspace.

Add a Start component to mark the beginning of subjob B and link it to subjob A using an OnSubjobOk trigger.

Design subjob B by adding components and links to it after the Start component in the Designer workspace.

Add a tJobletTriggerInput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.

Add a tJobletTriggerOutput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.

Drag your Joblet C from the Repository tree view to the Designer workspace between subjob A and subjob B.

Link your Joblet C to subjob A using an OnComponentOk trigger from the last component of subjob A to the tJobletTriggerInput component of your Joblet C.

Link your Joblet C to subjob B using an OnComponentOk trigger from the tJobletTriggerOutput component of your Joblet C to the Start component of subjob B.

The minimum requirements to orchestrate this are adding TRIGGER_INPUT and TRIGGER_OUTPUT components into C and linking A, B, and C using OnSubjobOk triggers. These are generic components that allow you to define triggers for your Joblet without depending on specific components. You do not need to add TRIGGER_INPUT and TRIGGER_OUTPUT components into A or B, as these are regular subjobs that can use any type of components or triggers.
