A specification that exposes the service on the node IP externally to the cluster include the following: B. type.
YAML Ain't Markup Language (YAML) refers to a human-readable data serialization language that is designed and developed for use in writing configuration files and software applications, wherein data are stored or transmitted.
By critically observing the "type: NodePort" specification in the given exhibit (service resource), we can reasonably infer and logically deduce that the service would be exposed on each Internet Protocol (IP) node at a static port (NodePort), thereby, making the service externally accessible to the cluster by using the nodeIP:nodePort format.
