Generate Auth token from the OCI console to access the OKE cluster using kubectl.

NO.24 Which kubectl command syntax is valid for implementing a rolling update deployment strategy in Kubernetes? (Choose the best answer.)

kubectl update <deployment-name> –image=image:v2

kubectl update -c <container> –iniage=image: v2

NO.25 You are using Oracle Cloud Infrastructure (OCI) Resource Manager to manage your infrastructure lifecycle and wish to receive an email each time a Terraform action begins. How should you use the OCI Events service to do this without writing any code?

Create a rule in OCI Events service matching the “Resource Manager Stack – Update” condition. Then select “Action Type: Email” and provide the destination email address.

Create an OCI Notifications topic and email subscription with the destination email address. Then create an OCI Events rule matching “Resource Manager Stack – Update” condition, and select the notification topic for the corresponding action.

Create an OCI Notification topic and email subscription with the destination email address. Then create an OCI Events rule matching “Resource Manager Job – Create” condition, and select the notification topic for the corresponding action.

Create an OCI Email Delivery configuration with the destination email address. Then create an OCI Events rule matching “Resource Manager Job – Create” condition, and select the email configuration for the corresponding action.

NO.26 What are the TWO main reasons you would choose to implement a serverless architecture? (Choose two.)

Easier to run long-running operations

Improved in-function state management

Reduced operational cost

Automatic horizontal scaling

No need for integration testing

NO.27 (CHK_4>2) You have a scenario where a DevOps team wants to store secrets in Oracle Cloud Infrastructure (OCI) Vault so that it can inject the secrets into an app’s environment variables (for example, MYSQL_DB_PASSWD) at deployment time. Which is NOT valid about managing secrets in the OCI Vault service?

New secret versions automatically expire in 90 days unless you configure an expiry rule.

You can manually create new secrets as well as new secret versions using the OCI Console:

A secret reuse rule prevents the use of secret contents across different versions of a secret.

A unique OCID is automatically generated for each secret and remains unchanged even when creating a new secret version.

NO.28 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

NO.29 You are developing a polyglot serverless application using Oracle Functions. Which language cannot be used to write your function code?

PL/SQL

Python

Node.js

Go

Java

NO.30 What are the TWO main reasons you would choose to implement a serverless architecture? (Choose two.)

No need for integration testing

Automatic horizontal scaling

Easier to run long-running operations

Reduced operational cost

Improved in-function state management

NO.31 A Docker image consists of one or more layers, each of which represents a Dockerfile instruction. The layers are stacked and each one is a delta of the changes from the previous layer. What permission is associated with these layers?

read mostly

write only

movable

read only

write once

NO.32 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.)

Terraform

Big Data

Anomaly Detection

Service Mesh

Docker

Kubemetes

NO.33 Oracle Functions monitors all deployed functions and collects and reports various metrics. Which is NOT available when viewing the Application metrics in the Oracle Cloud Infrastructure (OCI) Console?

The length of time a function runs for.

The number of retries made by the function before failing due to an error.

The number of requests to invoke a function that failed due to throttling.

The number of requests to invoke a function that failed with an error response.

NO.34 Which TWO are required to access the Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster from the kubectl CLI? (Choose two.)

Install and configure the OCI CLI.

OCI Identity and Access Management (IAM) Auth Token.

Tiller enabled on the OKE cluster.

An SSH key pair with the public key added to the cluster worker nodes.

A configured OCI API signing key pair.

NO.35 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 applicationlogs? (Choose the best answer.)

Set the OCI Logging option to Enabled for the cluster.

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

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

Enable monitoring for all worker nodes in the cluster.

NO.36 Your team has chosen to use master encryption key (MEK) within an Oracle Cloud Infrastructure (OCI) Vault for encrypting Kubernetes secrets associated with your microservice deployments in OCI Container Engine for Kubernetes (OKE) clusters so that you can easily manage key rotation. Which of the following is NOT valid about rotating keys in the OCI Vault service?

Once rotated, older key versions can be used for encryption until they are deleted.

Both software and HSM-protected MEKS can be rotated.

When you rotate an MEK, a new key version is automatically generated.

Each key version is tracked internally with separate unique OCIDS.

NO.37 As a cloud-native developer, you are designing an application that depends on Oracle Cloud Infrastructure (OCI) Object Storage wherever the application is running. Therefore, provisioning of storage buckets should be part of your Kubernetes deployment process for the application. Which of the following should you leverage to meet this requirement? (Choose the best answer.)

Oracle Functions

OCI Service Broker for Kubernetes

Open Service Broker API

OCI Container Engine for Kubernetes

NO.38 Which is NOT a valid backend-type option available when configuring an Oracle Cloud Infrastructure (OCI) API Gateway Deployment?

HTTP_BACKEND

ORACLE STREAMS_BACKEND

ORACLE_FUNCTIONS_BACKEND

NO.39 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?

idle-timeout

access-timeout

timeout

None, as this time is not configurable.

NO.40 You are a developing a microservices application that will be a consumer of the Oracle CloudInfrastructure (OCI) Streaming service. Which API method should you use to read and process a stream?

ReadMessages

ReadStream

Penetration testing

Automated testing

Integration testing

A/B testing

NO.42 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 answer.)

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.
