To determine which media communication type does not require media arbitration in the data link layer, let’s analyze each option:

1. **Deterministic**: This type of communication means that the communication patterns are predictable and controlled. It does not require media arbitration because devices can know when to send data without collisions.

2. **Controlled Access**: This approach incorporates some form of arbitration, as devices must determine when it is their turn to send data. Controlled access methods require coordination to avoid collisions, thus they do not fit the requirement of not needing arbitration.

3. **Full-Duplex**: In full-duplex mode, both ends of the communication can send and receive data simultaneously. This does not inherently require media arbitration for the direction of communication, but it can exist in environments where arbitration is still necessary to manage shared resources.

4. **Half-Duplex**: This allows communication in both directions but not at the same time. Therefore, half-duplex systems usually need media arbitration to manage which device can send or receive at any given time to prevent collisions.

### Analysis
- **Deterministic** communication allows for structured, predictable access without the need for additional arbitration processes.
- Both **controlled access** and **half-duplex** entail arbitration mechanisms to manage transmissions.

### Verification
Thus, deterministic communication stands out as it allows for structured access without requiring arbitration.

### Final Answer
**Deterministic communication** type does not require media arbitration in the data link layer.
