You want to push a new image in the Oracle Cloud Infrastructure (OCI) Registry. Which TWO actions would you need to perform? (Choose two.)

• Generate an API signing key to complete the authentication via Docker CLI.
• Generate an auth token to complete the authentication via Docker CLI.
• Assign an OCI defined tag via OCI CLI to the image.
• Assign a tag via Docker CLI to the image.
• Generate an OCI tag namespace in your repository.

Who is responsible for patching, upgrading, and maintaining the worker nodes in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE)? (Choose the best option.)

• Oracle Support
• It is automated
• The user
• Independent Software Vendors

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 option.)

• The Content-Type header must be set to application/json
• 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.
• An HTTP 401 will be returned if the client's clock is skewed more than 5 minutes from the server's.

Your company has recently deployed a new web application that uses Oracle Functions. Your manager instructs you to implement monitoring metrics to manage your systems more effectively. You know that Oracle Functions automatically monitors functions on your behalf and reports metrics via Oracle Cloud Infrastructure (OCI) Monitoring. Which TWO metrics are collected and made available by this feature? (Choose two.)

• Amount of CPU used by a function
• Length of time a function runs
• Number of times a function Is removed
• Amount of RAM used by a function
• Number of times a function is invoked

You are developing a serverless application with Oracle Functions and Oracle Cloud Infrastructure Object Storage. Your function needs to read a JSON file object from an Object Storage bucket named "input-bucket" in compartment "qa-compartment". Your corporate security standards mandate the use of Resource Principals for this use case. Which two statements are needed to implement this use case? (Choose two.)

• Set up a policy to grant all functions read access to the bucket: allow all functions in compartment qa-compartment to read objects in target.bucket.name= "input-bucket'
• Set up a policy to grant your user account read access to the bucket: allow user XYZ to read objects in compartment qa-compartment where target.bucket.name= "input-bucket'
• Set up the following dynamic group for your function's OCID: Name: read-file-dg Rule: resource.id= "ocid1.fnfunc.oc1.phx.aaaaaaaakeaobctakezjz5i4ujj7g25q7sx5m vr55pms6f4da'
• No policies are needed. By default, every function has read access to Object Storage buckets in the tenancy.
• Set up a policy with the following statement to grant read access to the bucket: allow dynamic- group read-file-dg to read objects in compartment qa- compartment where target.bucket.name= 'input-bucket'

A developer has created another version of a microservice and wants 10% of the traffic to flow towards it for testing purposes. The application is already configured using OCI (Oracle Cloud Infrastructure) Service Mesh. Which of the following steps is the right approach to achieve this goal?

• Create a new Kubernetes deployment for the new version of the microservice and set the traffic splitting percentage to 10% in the Kubernetes service manifest.
• Use Kubernetes HPA (Horizontal Pod Autoscaler) to scale the new version of the microservice to handle 10% of the traffic automatically.
• Create a new entry in the routeRules field of the ingress gateway route table manifest to configure traffic splitting between the old and new versions of the microservice and set the percentage to 10%.
• Create a new entry in the routeRules field of the virtual service route table manifest to configure traffic splitting between the old and new versions of the microservice and set the percentage to 10%.

Which feature is typically NOT associated with Cloud Native?

• Immutable Infrastructure
• Declarative APIs
• Containers
• Application Servers
• Service Meshes

As a developer, you have been tasked with implementing a microservices-based application. Which THREE technologies are best suited to accomplish the task? (Choose three.)

• Service Mesh
• Docker
• Kubemetes

Which is the smalled unit of Kubernetes architecture?

• Node
• Container
• Cluster
• Pod

From a DevOps process standpoint, it is a good practice to keep changes to an application under version control. Which of the following allows changes to a Docker image to be stored in a version control system?

• Updating docker-compose.yml
• Executing docker commit
• Executing docker save
• Updating Dockerfile
