OCI Developer 1Z0-1084 Questions and Answers 100% Pass Which one of the following is NOT a valid backend-type supported by Oracle Cloud Infrastructure (OCI) API Gateway? STOCK_RESPONSE_BACKEND HTTP_BACKEND ORACLE_FUNCTIONS_BACKEND ORACLE_STREAMS_BACKEND ORACLE_STREAMS_BACKEND Explanation In the API Gateway service, a back end is the means by which a gateway routes requests to the back-end services that implement APIs. If you add a private endpoint back end to an API gateway, you give the API gateway access to the VCN associated with that private endpoint. You can also grant an API gateway access to other Oracle Cloud Infrastructure services as back ends. For example, you could grant an API gateway access to Oracle Functions, so you can create and deploy an API that is backed by a serverless function.API Gateway service to create an API gateway, you can create an API deployment to access HTTP and HTTPS You are tasked with developing an application that requires the use of Oracle Cloud Infrastructure (OCI) APIs to POST messages to a stream in the OCI Streaming service. Which statement is incorrect? An HTTP 401 will be returned if the client's clock is skewed more than 5 minutes from the server's. The request must include an authorization signing string including (but not limited to) x-content- sha256, content-type, and content-length headers. The request does not require an Authorization header. The Content-Type header must be Set to application/json No header needed Explanation Emits messages to a stream. There's no limit to the number of messages in a request, but the total size of a message or request must be 1 MiB or less. The service calculates the partition ID from the message key and stores messages that share a key on the same partition. If a message does not contain a key or if the key is null, the service generates a message key for you. The partition ID cannot be passed as a parameter. POST Which statement accurately describes Oracle Cloud Infrastructure (OCI) Load Balancer integration with OCI Container Engine for Kubernetes (OKE)? OKE service provisions an OCI Load Balancer instance for each Kubernetes service with Load Balancer type in the YAML configuration. OKE service provisions a single OCI Load Balancer instance shared with all the Kubernetes services with Load Balancer type in the YAML configuration. OCI Load Balancer instance must be manually provisioned for each Kubernetes service that requires traffic balancing. OCI Load Balancer instance provisioning is triggered by OCI Events service for each Kubernetes service with Load Balancer type in the YAML configuration. OKE service provisions a single OCI Load Balancer instance shared with all the Kubernetes services with LoadBalancer type in the YAML configuration Explanation If you are running your Kubernetes cluster on Oracle Container Engine for Kubernetes (commonly known as OKE), you can have OCI automatically provision load balancers for you by creating a Service of type LoadBalancer instead of (or in addition to) installing an ingress controller like Traefik or Voyage YAML file When you apply this YAML file to your cluster, you will see the new service is created. After a short time (typically less than a minute) the OCI Load Balancer will be provisioned. Which two are characteristics of microservices? Microservices are hard to test in isolation. Microservices
