Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run a quick discovery scan to automatically regenerate the manual application service relationships.
Why it's wrong here
Incorrect. Discovery does not automatically repopulate manually maintained Application Services.
- ✗
Convert the manual Application Service into a Business Application record.
Why it's wrong here
Incorrect. Converting it to a Business Application removes its ability to track runtime dependencies.
- ✓
Re-establish the infrastructure CIs and manually re-add them to the Application Service via the Application Service Workbench.
Why this is correct
Correct. Manual Application Services require manual relationship maintenance when underlying CIs change.
- ✗
Delete the Business Application and recreate it as a Technical Service.
Why it's wrong here
Incorrect. This does not address the missing infrastructure relationships.
