Which TWO are characteristics of microservices? (Choose two.)

• Microservices communicate over lightweight APIs.
• Microservices can be implemented in limited number of programming languages.
• All microservices share a data store.
• Microservices are hard to test in isolation.
• Microservices can be independently deployed.

You have two microservices, A and B, running in production. Service A relies on APIs from service B. You want to test changes to service A without deploying all of its dependencies, which include service B. Which approach should you take to test service A?

• Test using API mocks.
• Test the APIs in private environments.
• Test against production APIs.
• There is no need to explicitly test APIs.

In the shared responsibility model, who should perform patching, upgrading, and maintaining of the worker nodes in provisioned Oracle Container Engine for Kubernetes (OKE) clusters?

• Oracle Support does it.
• It is the responsibility of the customer.
• It is an automated process.

Which command is used to get a Docker image from Oracle Cloud Infrastructure Registry (OCIR) to the client machine?

• docker pull .ocir.io//:
• docker pull /.ocir.io/:
• docker fetch .ocir.io//:
• docker fetch /.ocir.io/:

Which THREE are valid statements regarding the OCI Container Engine for Kubernetes (OKE) service? (Choose three.)

• You must have access to an Oracle Cloud Infrastructure tenancy. Your tenancy must have sufficient quota on different types of resources.
• OKE cannot use existing network resources for the creation of a new cluster.
• OKE automatically creates and configures new network resources for the new cluster.
• There is a limit of three clusters within each region, but there is no limit on the number of nodes and pods you can create within each cluster.

What can you use to dynamically make Kubernetes resources discoverable to public DNS servers? (Choose the best answer.)

• kubeDNS
• DynDNS
• CoreDNS
• ExternalDNS

You have two microservices, A and B running in production. Service A relies on APIs from service B. You want to test changes to service A without deploying all of its dependencies, which includes service B. Which approach should you take to test service A?

• Test using a previous test version of service B.
• Test using an API mock of service B.
• Test using the current production version of service B.
• This is not possible because service B is a dependency.

(CHK_1>3) You have an e-commerce application that loads customers' transactional data into the Oracle Cloud Infrastructure (OCI) Streaming service. The data must now be extracted and transformed before sending it to a third-party REST endpoint. You have been directed to leverage the OCI Service Connector Hub to automate this process. Which configuration option would address this requirement?

• Configure a new service connector as follows: • Source: Streaming • Task: Functions • Target: Functions
• Configure a new service connector as follows: • Source: Streaming • Task: API Gateway • Target: Notifications
• Configure a new service connector as follows: • Source: Streaming • Task: None • Target: Notifications
• Configure a new service connector as follows: • Source: Streaming • Task: API Gateway • Target: Functions
• Configure a new service connector as follows: • Source: Streaming • Task: Functions • Target: API Gateway

Which is NOT a valid option to execute a function deployed in Oracle Functions?

• Invoke from the Docker CLI.
• Send signed HTTP requests to the function's invoke endpoint.
• Invoke from the Fn Project CLI.
• Trigger by an event in the Oracle Cloud Infrastructure (OCI) Events service.
• Invoke from the OCI CLI.

Which is ONE of the differences between a microservice and a serverless function?

• Microservices are used for long running operations while serverless functions are used for short running operations.
• Microservices are triggered by events while serverless functions are not.
• Microservices are stateless while serverless functions are stateful.
• Microservices always use a data store while serverless functions never use a data store.
