Question 1

Assuming that your function does NOT have the --provisioned-concurrency option enabled, which parameter is used to configure the time period during which an idle function will remain in memory before Oracle Functions removes its container image from memory?

Options :

A : timeout

B : access-timeout

C : idle-timeout

D : None, as this time is not configurable

Answer: C

Question 2

Your organization has deployed their e-commerce application on Oracle Container Engine for Kubernetes (OKE) and they are using the Oracle Cloud Infrastructure Registry (OCIR) service as their Docker image repository. They have deployed the OKE cluster using the 'custom create' option, and their Virtual Cloud Network (VCN) has three public subnets with associated Route Tables, Security Lists, and Internet Gateway. However, their application containers are failing to deploy. On investigation, they discover that the images are not being pulled from the designated OCIR repository, even though the YAML configuration has the correct path to the images. What is a valid concern here that needs to be further investigated?

Options :

A : Security List rule for TCP port 22 needs to be added to connect to the OCIR service.

B : VCN hosting the OKE cluster worker nodes needs to have a NAT gateway to access OCIR repositories.

C : Identity and Access Management (IAM) credentials need to be added for each user that deploys applications to the OKE cluster

D : OKE cluster needs to have a secret with the credentials of their OCIR repository and use that secret in the Kubernetes deployment manifest.

Answer: D

Question 3

You are tasked with developing an application that requires the use of Oracle Cloud Infrastructure (OCI) APIsto POST messages to a stream in the OCI Streaming service.Which statement is incorrect?

Options :

A : The request must include an authorization signing string including (but not limited to) x-content-sha256, content-type, and content-length headers.

B : The Content-Type header must be Set to application/j son

C : An HTTP 401 will be returned if the client-s clock is skewed more than 5 minutes from the server's.

D : The request does not require an Authorization header.

Answer: D

Question 4

Your organization uses a federated identity provider to login to your Oracle Cloud Infrastructure (OCI) environment. As a developer, you are writing a script to automate some operation and want to use OCI CLI to do that. Your security team doesn't allow storing private keys on local machines. How can you authenticate with OCI CLI?

Options :

A : Run oci setup keys and provide your credentials

B : Run oci session refresh —profile < profile_name >

C : Run oci session authenticate and provide your credentials

D : Run oci setup oci-cli-rc —file path/to/target/file

Answer: C

Question 5

You developed a microservices-based application that runs in an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. It has multiple endpoints that need to be exposed to the public internet. What is the most cost-effective way to expose multiple application endpoints without adding unnecessary complexity to the application?

Options :

A : Use a NodePort service type in Kubernetes for each of your service endpoints using the node-s public IP address to access the applications.

B : Create a separate load balancer instance for each service using the lowest 100 Mbps option.

C : Use a ClusterIP service type in Kubernetes for each of your service endpoints using a load balancer to expose the endpoints

D : Deploy an Ingress Controller and use it to expose each endpoint with its own routing endpoint.
