Which of the following makes a conflict when merging two branches in Decision Center?

Question

Options

• AWhen a snapshot is created in one of the branches
• BWhen a new ruleflow is created in one of the branches
• CWhen the same decision table is modified in both branches
• DWhen an action rule is modified from Rule Designer in one of the branches

• A
  88% (28)
• B
  3% (1)
• C
  6% (2)
• D
  3% (1)

Explanation

Snapshots in IBM ODM Decision Center represent frozen, immutable checkpoints of a branch's state. When a branch containing a snapshot is merged, Decision Center cannot automatically reconcile that locked state with the evolving content of the other branch, creating an unresolvable conflict in the merge process.

Why the distractors are wrong:

• B (new ruleflow in one branch): Adding a new artifact to only one branch isn't a conflict - Decision Center simply includes the new ruleflow in the merged result since there's nothing to collide with.
• C (same decision table modified in both): While this looks like a classic VCS conflict, Decision Center's merge handles same-artifact edits by surfacing the differences for manual resolution - it's a difference, not a blocking conflict.
• D (action rule modified via Rule Designer): Rule Designer modifications sync back to Decision Center, but the editing tool used doesn't itself introduce a merge conflict.

Memory tip: Think of a snapshot as a "sealed envelope" - once sealed, it can't be rewritten during a merge. Any branch carrying a sealed envelope forces Decision Center to stop and flag a conflict because it can't open or overwrite the frozen contents.
