Application Deployment and Operations

Question

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 be deployed, upgraded, scaled, and restarted independently of other services in the application as part of an automated system.
  • Enable frequent updates to live applications without affecting live services for users. Which component does a cloud native network function provide in the deployment?

Why each option

A cloud native network function (CNF) provides managed orchestration, which handles service dependency management, automated independent lifecycle operations, and rolling updates for microservices without impacting live users.

Aresilient services

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.

Bcontinuous automation

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.

Cmanaged orchestrationCorrect

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.

Ddiscovery mechanisms

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.
