Correct Answer: CE

Fn Project CLI you can create an Fn Project CLI Context to Connect to Oracle Cloud Infrastructure and specify -- provider oracle This option enables Oracle Functions to perform authentication and authorization using Oracle Cloud Infrastructure request signing, private keys, user groups, and policies that grant permissions to those user groups.

Correct Answer: A

microservice is larger and can do more than a function. A function is a relatively small bit of code that performs only one action in response to an event. In many cases, microservices can be decomposed into a number of smaller stateless functions. The difference between microservices and functions is not simply the size. Functions are stateless, and they require no knowledge about or configuration of the underlying server--hence, the term serverless. https://developer.oracle.com/java/fn-project-introduction.html

Correct Answer: A

https://docs.cloud.oracle.com/en-us/iaas/Content/Events/Concepts/eventsoverview.htm ACTIONS Event Rules must also specify an action to trigger when the filter finds a matching event. Actions are responses you define for event matches. You set up select Oracle Cloud Infrastructure services that the Events service has established as actions. The resources for these services act as destinations for matching events. When the filter in the rule finds a match, the Events service delivers the matching event to one or more of the destinations you identified in the rule. The destination service that receives the event then processes the event in whatever manner you defined. This delivery provides the automation in your environment. You can only deliver events to certain Oracle Cloud Infrastructure services with a rule. Use the following services to create actions: Notifications Streaming Functions

Correct Answer: A

The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution.

Correct Answer: D

TocPath=Services%7CExample%2 0Network%20Resource%20Configuration%7CUpgrading%20the% 20Version%20of%20Kubernetes%2 0Running%20on%20a%20Master%20Node%7C_____2 Creating Internal Load Balancers in Public and Private Subnets You can create Oracle Cloud Infrastructure load balancers to control access to services running on a cluster: When you create a 'custom' cluster, you select an existing VCN that contains the network resources to be used by the new cluster. If you want to use load balancers to control traffic into the VCN, you select existing public or private subnets in that VCN to host the load balancers. When you create a 'quick cluster', the VCN that's automatically created contains a public regional subnet to host a load balancer. If you want to host load balancers in private subnets, you can add private subnets to the VCN later.

Alternatively, you can create an internal load balancer service in a cluster to enable other programs running in the same VCN as the cluster to access services in the cluster. You can host internal load balancers in public subnets and private subnets. To create an internal load balancer hosted on a public subnet, add the following annotation in the metadata section of the manifest file: service.beta.kubernetes.io/oci-load-balancer-internal: "true" To create an internal load balancer hosted on a private subnet, add both following annotations in the metadata section of the manifest file: service.beta.kubernetes.io/oci-load-balancer-internal: "true" service.beta.kubernetes.io/oci-load-balancersubnet1: "ocid1.subnet.oc1..aaaaaa....vdfw" where ocid1.subnet.oc1..aaaaaa....vdfw is the OCID of the private subnet.

Correct Answer: AB

You use the Docker CLI to push images to Oracle Cloud Infrastructure Registry. To push an image, you first use the docker tag command to create a copy of the local source image as a new image (the new image is actually just a reference to the existing source image). As a name for the new image, you specify the fully qualified path to the target location in Oracle Cloud Registry where you want to push the image, optionally including the name of a repository. for more details check the below link

Correct Answer: A

The minimum amount of persistent storage that a PVC can request is 50 gigabytes. If the request is for less than 50 gigabytes, the request is rounded up to 50 gigabytes. https://docs.cloud.oracle.com/en-us/iaas/Content/ContEng/Tasks/ contengcreatingpersistentvolumeclaim.htm

Correct Answer: C

In the API Gateway service, a back end is the means by which a gateway routes requests to the back- end services that implement APIs. If you add a private endpoint back end to an API gateway, you give the API gateway access to the VCN associated with that private endpoint. You can also grant an API gateway access to other Oracle Cloud Infrastructure services as back ends. For example, you could grant an API gateway access to Oracle Functions, so you can create and deploy an API that is backed by a serverless function. API Gateway service to create an API gateway, you can create an API deployment to access HTTP and HTTPS URLs. https://docs.cloud.oracle.com/en-us/iaas/Content/APIGateway/Tasks/ apigatewayusinghttpbackend.htm API Gateway service to create an API gateway, you can create an API deployment that invokes serverless functions defined in Oracle Functions. https://docs.cloud.oracle.com/en-us/iaas/Content/APIGateway/Tasks/ apigatewayusingfunctionsbackend.htm API Gateway service, you can define a path to a stock response back end https://docs.cloud.oracle.com/en-us/iaas/Content/ APIGateway/Tasks/ apigatewayaddingstockresponses.htm
