Question 6

With the volume of communication that can happen between different components in cloud-native applications, it is vital to not only test functionality, but also service resiliency. Which statement is true with regards to service resiliency? (Choose the best answer.)

  1. Resiliency is about recovering from failures without downtime or data loss.
  2. A goal of resiliency is not to bring a service to a functioning state after a failure.
  3. Resiliency testing can be only done in a test environment.
  4. Resiliency is about avoiding failures.

Question 7

Which two are required to enable Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster access from the kubectl CLI? (Choose two.)

  1. An SSH key pair with the public key added to cluster worker nodes.
  2. Install and configure the OCI CLI
  3. OCI Identity and Access Management Auth Token
  4. Tiller enabled on the OKE cluster
  5. A configured OCI API signing key pair

Question 8

You have a containerized app that requires an Autonomous Transaction Processing (ATP) Database. Which option is not valid for connecting to ATP from a container in Kubernetes? (Choose the best answer.)

  1. Enable Oracle REST Data Services for the required schemas and connect via HTTPS.
  2. Create a Kubernetes secret with contents from the instance Wallet files. Use this secret to create a volume mounted to the appropriate path in the application deployment manifest.
  3. Use Kubernetes secrets to configure environment variables on the container with ATP instance OCID, and OCI API credentials. Then use the CreateConnection API endpoint from the service runtime.
  4. Install the Oracle Cloud Infrastructure Service Broker on the Kubernetes cluster and deploy ServiceInstance and ServiceBinding resources for ATP. Then use the specified binding name as a volume in the application deployment manifest.

Question 9

In order to effectively test your cloud-native applications, you might utilize separate environments (development, testing, staging, production, etc.) Which Oracle Cloud Infrastructure (OCI) service can you use to create and manage your infrastructure? (Choose the best answer.)

  1. OCI Compute
  2. OCI Container Engine for Kubernetes
  3. OCI Resource Manager
  4. OCI API Gateway

Question 10

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? (Choose the best answer.)

  1. The request must include an authorization signing string including (but not limited to) x-content-sha256, content-type, and content-length headers.
  2. The Content-Type header must be set to application/json
  3. An HTTP 401 will be returned if the client's clock is skewed more than 5 minutes from the server's.
  4. The request does not require an Authorization header.
