Oracle 1Z0-1084-24 Online Questions & Answers

• Question 81:

  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?

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

• Question 82:

  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?

  A. Test using API mocks.
  B. Test the APIs in private environments.
  C. Test against production APIs.
  D. There is no need to explicitly test APIs.
  A. Test using API mocks.

• Question 83:

  Which statement about microservices is FALSE?

  A. They are typically designed around business capabilities.
  B. It is fairly common for them to communicate with HTTP.
  C. Multiple microservices can run in one process.
  D. They are independently deployable.
  B. It is fairly common for them to communicate with HTTP.

  D. Application Servers

• Question 85:

  As a Cloud Native developer, you have written a web service for your company. However, your security team has suggested that your web service should address Distributed Denial- of-Service (DDoS) attack.

  A. Use a third party service integration to Implement DDoS attack mitigation.
  B. Re-write your web service and implement rate limiting.
  C. Use the OCI Virtual Cloud Network (VCN) segregation to control DDoS.
  D. Use the OCI API Gateway service and configure rate limiting.
  D. Use the OCI API Gateway service and configure rate limiting.

• Question 86:

  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 regarding service resiliency?

  A. Resiliency is about avoiding failures.
  B. Resiliency testing can be done only in a test environment.
  C. Resiliency is about recovering from failures without downtime or data loss.
  D. Resiliency is about not bringing a service to a functioning state after a failure.
  C. Resiliency is about recovering from failures without downtime or data loss.

• Question 87:

  You are building a container image and pushing it to Oracle Cloud Infrastructure Registry (OCIR). You need to ensure that these images never get deleted from the repository. Which action should you take?

  A. Create a group and assign a policy to perform lifecycle operations on images.
  B. Write a policy to limit access to the specific repository in your compartment.
  C. Edit the tenancy global retention policy.
  D. Set global policy of image retention to "Retain All Images".
  D. Set global policy of image retention to "Retain All Images".

• Question 88:

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

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

  B. Length of time a function runs
  C. Number of times a function Is removed
  D. Amount of RAM used by a function
  E. Number of times a function is invoked
  A. Amount of CPU used by a function
