What should you do in this scenario?
(Choose the best answer.)

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.

A.

Streaming

B.

Email

C.

Notifications

D.

Functions

A.

Invoke from the Docker CLI.

B.

Send signed HTTP requests to the function's invoke endpoint.

C.

Invoke from the Fn Project CLI.

D.

Trigger by an event in the Oracle Cloud Infrastructure (OCI) Events service.

E.

Question 5
Single choice

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.)

A.

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

B.

Set the OCI Logging option to Enabled for the cluster.

C.

Enable monitoring for all worker nodes in the cluster.

D.

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

Question 6
Single choice

As a Cloud Native developer, you develop two services in Node.js and deploy them to two different Container Engine for Kubernetes (OKE) clusters that use the same Virtual Cloud Network (VCN). Your security team wants to analyze the network communication between them.

How can this requirement be met in the most cost-effective way?

A.

Rewrite the application and send the application logs to an outside log aggregator.

B.

Deploy a third-party logging service and aggregate the network flow logs.

C.

Use the OCI Logging service and enable VCN flow logs.

D.

Deploy Wireshark and intercept the packets.

Question 7
Single choice

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.

Question 8
Multiple choice

Which TWO statements accurately describe an Oracle Functions application? (Choose two.)

A.

A common context to store configuration variables that are available to all functions in the application.
A Docker image containing all the functions that share the same configuration.

B.

An application based on Oracle Functions, Oracle Cloud Infrastructure (OCI) Events, and OCI API Gateway services.

C.

A small block of code invoked in response to an OCI Events service.
A logical group of functions.

D.

A Docker image containing all the functions that share the same configuration.

Question 9
Multiple choice

Which TWO statements are correct regarding Docker images and containers? (Choose two.)

A.

Only one container can be spawned from a given image at a time.

B.

An image is a collection of immutable layers whereas a container is a running instance of an image.

C.

If multiple containers are spawned from the same image, then they all use the same copy of that image in memory.

D.

Writing and building a new Dockerfile is the only way you can create new Docker images.

E.

A container can exist without an image but an image cannot exist without a container.

Question 10
Single choice

You deployed a Python application to an Oracle Container Engine for Kubernetes (OKE) cluster. However, while testing you found a bug, which you rectified and then created a new Docker image. You now need to ensure that if this new image does not work once deployed, you should be able to roll back to the previous version.
