There is no need to explicitly test APIs.

NEW QUESTION 27
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’

NEW QUESTION 28
You developed a microservices-based application that runs in an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. Your security team wants to use SSL termination for this application.
What should you do to create a secure SSL termination for this application using the fewest steps possible?

Create a self-signed certificate and its corresponding key. Create a Kubernetes secret using the certificate and the key. Then add these annotations to the Kubernetes service: annotations: service.beta.
kubernetes.io/oci-load-balancer-ssl-ports: “443” service.beta.kubernetes.io/oci-load-balancer-tls-secret:
ssl certificate-secret

Create a self-signed certificate and its corresponding key. Create a Kubernetes secret using the certificate and the key. Then add these annotations to the Kubernetes service: annotations: service.beta.
kubernetes.io/oci-load-balancer-ssl-ports: “443” service.beta.kubernetes.io/oci-load-balancer-security- list management-mode: “Frontend”

Add these annotations to the kubernetes service: annotations: service.beta.kubernetes.io/oci-load- balancer-ssl-ports: “443” service.beta.kubernetes.io/oci-load-balancer-ssl-secret-key: ssl secret-key

Generate a self-signed certificate using Let’s Encrypt. Use that certificate on OCI Load Balancer. Create the Kubernetes service using this load balancer.

The correct answer is: “Create a self-signed certificate and its corresponding key. Create a Kubernetes secret using the certificate and the key. Then add these annotations to the Kubernetes service: annotations: service.
beta.kubernetes.io/oci-load-balancer-ssl-ports: ‘443’ service.beta.kubernetes.io/oci-load-balancer-tls-secret: ssl certificate-secret.” To create a secure SSL termination for your microservices-based application running in an OCI Container Engine for Kubernetes (OKE) cluster, you can follow these steps: Create a self-signed certificate and its corresponding key: Generate a self-signed SSL certificate and its private key using a tool like OpenSSL. Create a Kubernetes secret: Create a Kubernetes secret using the certificate and key obtained in the previous step. This secret will securely store the certificate and key within the Kubernetes cluster. Add annotations to the Kubernetes service: Modify the Kubernetes service that exposes your application and add the following annotations to enable SSL termination: annotations: service.beta.kubernetes.io/oci-load- balancer-ssl-ports: ‘443’ (specify the SSL port as 443) annotations: service.beta.kubernetes.io/oci-load- balancer-tls-secret: ssl certificate-secret (specify the name of the Kubernetes secret containing the certificate and key) By following these steps, you can create a secure SSL termination for your application using a self- signed certificate and Kubernetes secret. The annotations added to the Kubernetes service ensure that the SSL port is configured correctly and the TLS secret is utilized for SSL termination when traffic reaches the load balancer. The other options provided are not the most suitable approaches for achieving secure SSL termination in an OCI Container Engine for Kubernetes (OKE) cluster: Adding annotations related to the OCI load balancer SSL secret key is not the correct approach for SSL termination in this scenario. Using Let’s Encrypt to generate a self-signed certificate and configuring it on the OCI Load Balancer is not necessary when you can create and manage the SSL certificate within the Kubernetes cluster using a Kubernetes secret.

NEW QUESTION 29
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.

NEW QUESTION 30

Python

Node.js

Go

Java

NEW QUESTION 31
Which testing measure should be considered when using test cases that simultaneously validate a deployment and perform a selected set of functional tasks?

NEW QUESTION 32
Having created a Container Engine for Kubernetes (OKE) cluster, you can use Oracle Cloud Infrastructure (OCI) Logging to view and search the logs of applications running on the worker node compute instances in the cluster. Which task is NOT required to collect and parse application logs? (Choose the best answer.)

Create a dynamic group with a rule that includes all worker nodes In the cluster.

Set the OCI Logging option to Enabled for the cluster.

Enable monitoring for all worker nodes in the cluster.

Configure a custom log in OCI Logging with the appropriate agent configuration.

NEW QUESTION 33
A developer using Oracle Cloud Infrastructure (OCI) API Gateway needs to authenticate the API requests to their web application.

Create a cross account functions authorizer.

Create an authorizer function using OCI Identity and Access Management 91AM) based authentication.

Create an authorizer function using request header authorization.

Create an authorizer function using token-based authorization.
