Applications in the Function services In Oracle Functions, an application is:

1.

a logical grouping of functions

2.

a common context to store configuration variables that are available to all functions in the application

When you define an application in Oracle Functions, you specify the subnets in which to run the functions in the application.

Correct Answer: D

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-balancer-subnet1: "ocid1.subnet.oc1..aaaaaa....vdfw" where ocid1.subnet.oc1..aaaaaa....vdfw is the OCID of the private subnet.

Correct Answer: F

Correct Answer: B

Oracle Cloud Infrastructure Events enables you to create automation based on the state changes of resources throughout your tenancy. Use Events to allow your development teams to automatically respond when a resource changes its state. Here are some examples of how you might use Events: Send a notification to a DevOps team when a database backup completes. Convert files of one format to another when files are uploaded to an Object Storage bucket. 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: D

Deleting an Image When you no longer need an old image or you simply want to clean up the list of image tags in a repository, you can delete images from Oracle Cloud Infrastructure Registry. Your permissions control the images in Oracle Cloud Infrastructure Registry that you can delete. You can delete images from repositories you've created, and from repositories that the groups to which you belong have been granted access by identity policies. If you belong to the Administrators group, you can delete images from any repository in the tenancy. Note that as well deleting individual images , you can set up image retention policies to delete images automatically based on selection criteria you specify (see Retaining and Deleting Images Using Retention Policies). Note: In each region in a tenancy, there's a global image retention policy. The global image retention policy's default selection criteria retain all images so that no images are automatically deleted.

However, you can change the global image retention policy so that images are deleted if they meet the criteria you specify. A region's global image retention policy applies to all repositories in the region, unless it is explicitly overridden by one or more custom image retention policies. You can set up custom image retention policies to override the global image retention policy with different criteria for specific repositories in a region. Having created a custom image retention policy, you apply the custom retention policy to a repository by adding the repository to the policy. The global image retention policy no longer applies to repositories that you add to a custom retention policy.

Correct Answer: C

Before using Oracle Functions, you have to set up an Oracle Cloud Infrastructure API signing key. The instructions in this topic assume:

-

you are using Linux

-

you are following Oracle's recommendation to provide a passphrase to encrypt the private key For more Detials Set up an Oracle Cloud Infrastructure API Signing Key for Use with Oracle Functions

Correct Answer: C

Invoking a function returns a FunctionInvokeSubnetNotAvailable message and a 502 error (due to a DHCP Options issue)

When you invoke a function that you've deployed to Oracle Functions, you might see the following error message:

{"code":"FunctionInvokeSubnetNotAvailable","message":"dhcp options ocid1.dhcpoptions........ does not exist or Oracle Functions is not authorized to use it"}

Fn: Error invoking function. status: 502 message: dhcp options ocid1.dhcpoptions........ does not exist or Oracle Functions is not authorized to use it If you see this error:

Double-check that a policy has been created to give Oracle Functions access to network resources.

Service Access to Network Resources

When Oracle Functions users create a function or application, they have to specify a VCN and a subnet in which to create them. To enable the Oracle Functions service to create the function or application in the specified VCN and subnet,

you must create an identity policy to grant the Oracle Functions service access to the compartment to which the network resources belong. To create a policy to give the Oracle Functions service access to network resources:

Log in to the Console as a tenancy administrator.

Create a new policy in the root compartment:

Open the navigation menu. Under Governance and Administration, go to Identity and click Policies. Follow the instructions in To create a policy, and give the policy a name (for example, functions- service-network-access).

Specify a policy statement to give the Oracle Functions service access to the network resources in the compartment:

Allow service FaaS to use virtual-network-family in compartment For example:

Allow service FaaS to use virtual-network-family in compartment acme-network Click Create.

Double-check that the set of DHCP Options in the VCN specified for the application still exists.

Correct Answer: A

"type": "STOCK_RESPONSE_BACKEND" indicates that the API gateway itself will act as the back end and return the stock response you define (the status code, the header fields and the body content). https://docs.cloud.oracle.com/en-us/iaas/Content/APIGateway/Tasks/apigatewayaddingstockresponses.htm
