Question

1 dnQuery = DnQuery( 'uni/tn-companyXYZ')
2 dnQuery.subtree = 'parent'
3 tenantMo = moDir.query(dnQuery)
4 defaultBDMo = tenantMo.BD['default']

Options

• ADelete line 2.
• BChange dnQuery to classQuery in line 1.
• CMove line 2 to the last line.
• DChange parent to children in line 2.

• A
  14% (5)
• B

• C

• D
  75% (27)

Explanation

Setting dnQuery.subtree = 'children' tells the ACI Cobra SDK to include child managed objects (like Bridge Domains) in the query response - without it, only the tenant MO itself is returned, making line 4's .BD['default'] lookup fail because no child objects were fetched. Option A (deleting line 2) fails for the same reason: the subtree scope is needed, just with the correct value. Option B (switching to ClassQuery) changes the query type entirely - a ClassQuery fetches all objects of a given class across the fabric, breaking the DN-scoped lookup and returning a flat list rather than a navigable object hierarchy. Option C (moving line 2 to last) is nonsensical because the query executes on line 3; setting subtree after the query has already run has zero effect on what was returned.

Memory tip: Think "to get the kids, ask for children" - subtree = 'children' fetches downward in the MIT (Management Information Tree), which is exactly what you need when navigating from a parent MO to its children.
