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

Specifying Alternative Load Balancer Shapes The shape of an Oracle Cloud Infrastructure load balancer specifies its maximum total bandwidth (that is, ingress plus egress). By default, load balancers are created with a shape of 100Mbps. Other shapes are available, including 400Mbps and 8000Mbps. https://docs.cloud.oracle.com/en-us/iaas/Content/ContEng/Tasks/contengcreatingloadbalancer.htm

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: A

https://blogs.oracle.com/cloud-infrastructure/introducing-service-broker-for-kubernetes OCI Service Broker for Kubernetes is an implementation of the Open Service Broker API. OCI Service Broker for Kubernetes is specifically for interacting with Oracle Cloud Infrastructure services from Kubernetes clusters. It includes three service broker adapters to bind to the following Oracle Cloud Infrastructure services: Object Storage Autonomous Transaction Processing Autonomous Data Warehouse

Correct Answer: A

Passing Custom Configuration Parameters to Functions he code in functions you deploy to Oracle Functions will typically require values for different parameters. Some pre-defined parameters are available to your functions as environment variables. But you'll often want your functions to use parameters that you've defined yourself. For example, you might create a function that reads from and writes to a database. The function will require a database connect string, comprising a username, password, and hostname. You'll probably want to define username, password, and hostname as parameters that are passed to the function when it's invoked. Using the Console To specify custom configuration parameters to pass to functions using the Console: Log in to the Console as a functions developer. In the Console, open the navigation menu. Under Solutions and Platform, go to Developer Services and click Functions. Select the region you are using with Oracle Functions. Oracle recommends that you use the same region as the Docker registry that's specified in the Fn Project CLI context (see 6. Create an Fn Project CLI Context to Connect to Oracle Cloud Infrastructure). Select the compartment specified in the Fn Project CLI context (see 6. Create an Fn Project CLI Context to Connect to Oracle Cloud Infrastructure). The Applications page shows the applications defined in the compartment. Click the name of the application containing functions to which you want to pass custom configuration parameters: To pass one or more custom configuration parameters to every function in the application, click Configuration to see the Configuration section for the application. To pass one or more custom configuration parameters to a particular function, click the function's name to see the Configuration section for the function. In the Configuration section, specify details for the first custom configuration parameter: Key: The name of the custom configuration parameter. The name must only contain alphanumeric characters and underscores, and must not start with a number. For example, username Value: A value for the custom configuration parameter. The value must only contain printable unicode characters. For example, jdoe Click the plus button to save the new custom configuration parameter. Oracle Functions combines the key-value pairs for all the custom configuration parameters (both application-wide and function-specific) in the application into a single, serially-encoded configuration object with a maximum allowable size of 4Kb. You cannot save the new custom configuration parameter if the size of the serially-encoded configuration object would be greater than 4Kb. (Optional) Enter additional custom configuration parameters as required.

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: D

In the API Gateway service, there are two types of policy:

-

a request policy describes actions to be performed on an incoming request from a caller before it is sent to a back end

-

a response policy describes actions to be performed on a response returned from a back end before it is sent to a caller

You can use request policies to:

-limit the number of requests sent to back-end services

-enable CORS (Cross-Origin Resource Sharing) support

-provide authentication and authorization

Correct Answer: C

Token-based authentication for the CLI allows customers to authenticate their session interactively, then

use the CLI for a single session without an API signing key. This enables customers using an identity

provider that is not SCIM- supported to use a federated user account with the CLI and SDKs.

Starting a Token-based CLI Session

To use token-based authentication for the CLI on a computer with a web browser:

In the CLI, run the following command. This will launch a web browser.

oci session authenticate

In the browser, enter your user credentials. This authentication information is saved to the .config file.
