Which two Cloud Pak for Data services support the multi-tenancy mechanism of installing the service...

Cloud Pak for Data supports service-level multi-tenancy by enabling some services to be installed centrally and then provisioned into user “tethered” namespaces (projects). In version 4.7, Analytics Engine (Apache Spark) and IBM Data Virtualization services support this tethered‑project model: they can be installed once and then instantiated per project across multiple tenants. Core services like Db2, Cognos Analytics, and Watson Pipelines in 4.7 require installation per instance and do not yet support tethered‑namespace provisioning via multi‑tenant model.
