Which three basic types of SD-WAN deployments are out on the market? (Choose three.)

SD-WAN as-a-Service involves consuming SD-WAN capabilities from a cloud provider, where the provider hosts and manages the SD-WAN infrastructure for the customer.

Secure SD-WAN service describes a feature or capability of an SD-WAN solution (security), not a distinct deployment type.

Internet-based SD-WAN leverages public internet connections as the primary transport for the WAN fabric, aiming for cost reduction and increased flexibility.

Policy-based SD-WAN describes a core operational characteristic of SD-WAN (centralized policy enforcement), not a specific deployment model.

Managed service SD-WAN is a model where a third-party service provider manages the entire SD-WAN solution, including deployment, operation, and maintenance, on behalf of the customer.

MPLS-based refers to a transport technology that can be used as an underlay network within an SD-WAN solution, but it is not a distinct type of SD-WAN deployment itself.
