A DevOps engineer must deploy several microservice applications with these requirements: The deployment must be configured to assist with dependencies between the applications. Each microservice must

Resilient services refer to fault-tolerance and high-availability design patterns such as circuit breakers and retries, not the orchestration capability needed to manage dependencies and independent lifecycle operations.

Continuous automation describes the CI/CD pipeline practice of building and testing code continuously, which is a broader DevOps toolchain concept rather than a specific CNF deployment component.

Managed orchestration in a CNF context - typically implemented via Kubernetes or a service mesh - automates the deployment, scaling, upgrade, and restart of each microservice independently while managing inter-service dependencies, enabling zero-downtime rolling updates so live user traffic is not disrupted during changes.

Discovery mechanisms refer to service discovery (DNS-based or registry-based) used to locate service endpoints, which is a subset of functionality rather than the overarching component satisfying all three deployment requirements stated.
