What are three characteristics of a master-detail relationship?

Question

Options

• APermissions for the detail record are set independently of the master.
• BThe master object can be a standard or custom object.
• CRoll-up summaries are supported in master-detail relationships.
• DThe owner field on the detail records is the owner of the master record.
• EEach object can have up to five master-detail relationships.

• A
  2% (1)
• B
  91% (48)
• E
  8% (4)

Explanation

In a master-detail relationship, the master object can be either a standard (e.g., Account, Opportunity) or custom object (B), roll-up summary fields (COUNT, SUM, MIN, MAX) are exclusively available on the master object (C), and the detail record inherits its owner from the master - it has no independent Owner field (D).

Why the distractors are wrong:

• A describes lookup relationship behavior - in master-detail, security and sharing cascade from the master, so detail permissions are not independent.
• E is off by a factor: each object supports up to two master-detail relationships, not five.

Memory tip: Think of master-detail as a strict parent-child relationship - the child (detail) can't own itself, can't set its own permissions, and the parent can tally up the children (roll-up summaries). The "two, not five" limit for master-detail relationships is a common trap - associate it with "a child can have at most two parents."
