The code snippet is intended to access a child managed object within Cisco’s ACI. The current placement of line 2 (dnQuery.subtree = 'parent') specifies that the query should look at the parent objects, not the children. To fix the code so that it accesses a child managed object, line 2 should be moved to after line 3, where tenantMo is defined. This change will ensure that the subtree of tenantMo is set to ‘parent’, which means that when defaultBDmo is called in line 4, it will correctly reference a child managed object under tenantMo. References :=
