Question 1 of 60

Which statement accurately describes Oracle Cloud Infrastructure (OCI) Load Balancer integration with OCI Container Engine for Kubernetes (OKE)? (Choose the best answer.)

OKE service provisions an OCI Load Balancer instance for each Kubernetes service with LoadBalancer type in the YAML configuration.

OCI Load Balancer instance provisioning is triggered by OCI Events service for each Kubernetes service with LoadBalancer type in the YAML configuration.

OCI Load Balancer instance must be manually provisioned for each Kubernetes service that requires traffic balancing.

OKE service provisions a single OCI Load Balancer instance shared with all the Kubernetes services with LoadBalancer type in the YAML configuration.

Correct Answer: A

The Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) service automatically provisions an OCI Load Balancer instance for each Kubernetes service that is defined with the LoadBalancer type in the YAML configuration. This automated provisioning ensures that each service can properly manage and balance its own inbound traffic without manual intervention or sharing a single load balancer among multiple services, making option A the accurate description.

Question 2 of 60

Per CAP theorem, in which scenario do you NOT need to make any trade-off between the guarantees? (Choose the best answer.)

when the are no network partitions

when the system is running in the cloud

when the system is running on-premise

when you are using load balancers

Correct Answer: A

According to the CAP theorem, you are required to make trade-offs between consistency, availability, and partition tolerance in distributed systems. However, if there are no network partitions, you do not need to make any trade-offs between the guarantees. In this scenario, you can achieve both consistency and availability since the network is functioning perfectly without any partition splitting the nodes. Therefore, the correct answer is when there are no network partitions.

Question 3 of 60

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? (Choose the best answer.)

Test against production APIs.

Test using API mocks.

There is no need to explicitly test APIs.

Test the APIs in private environments.

Correct Answer: B

To test changes to service A without deploying all of its dependencies, including service B, the best approach is to use API mocks. By using API mocks, you can simulate the behavior of the APIs from service B, allowing you to verify the functionality of service A independently. This approach helps in isolating and quickly identifying issues within service A without the need for the actual deployment of service B.

Question 4 of 60

In a Linux environment, what is the default location of the configuration file that Oracle Cloud Infrastructure CLI uses for profile information? (Choose the best answer.)

/etc/.oci/config

/usr/local/bin/config

$HOME/.oci/config

/usr/bin/oci/config

Correct Answer: C

In a Linux environment, the default location of the configuration file that Oracle Cloud Infrastructure CLI (OCI CLI) uses for profile information is $HOME/.oci/config. This path refers to a hidden directory named .oci in the user's home directory, where the configuration file named config resides. This is the standard and recommended location for storing OCI CLI configuration files to ensure they are easily accessible yet kept secure within the user's home directory.

Question 5 of 60

Which statement is incorrect with regards to the Oracle Cloud Infrastructure (OCI) Notifications service? (Choose the best answer.)

Notification topics may be assigned as the action performed by an OCI Events configuration.

OCI Alarms can be configured to publish to a notification topic when triggered.

An OCI function may subscribe to a notification topic.

A subscription can forward notifications to an HTTPS endpoint.

A subscription can integrate with PagerDuty events.

It may be used to receive an email each time an OCI Autonomous Database backup is completed.

Correct Answer: F

The Oracle Cloud Infrastructure (OCI) Notifications service is used to send alerts and messages based on pre-set triggers and conditions related to various OCI services. While it is true that notification topics can be configured as actions in response to OCI Events (A), can publish messages when OCI Alarms are triggered (B), can be subscribed to by an OCI function (C), can forward notifications to HTTPS endpoints (D), and can integrate with PagerDuty events (E), it cannot inherently be used to receive an email each time an OCI Autonomous Database backup is completed (F) without involving additional services like OCI Events. Thus, the incorrect statement is that the OCI Notifications service alone can be used for receiving an email each time an Autonomous Database backup is completed.
