You can invoke a function that you've deployed to Oracle Functions in different ways:

Using the Fn Project CLI.

Using the Oracle Cloud Infrastructure CLI.

Using the Oracle Cloud Infrastructure SDKs.

Making a signed HTTP request to the function's invoke endpoint. Every function has an invoke endpoint.

Each of the above invokes the function via requests to the API. Any request to the API must be authenticated by including a signature and the OCID of the compartment to which the function belongs in the request header. Such a request is

referred to as a 'signed' request. The signature includes Oracle Cloud Infrastructure credentials in an encrypted form.

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

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.

Correct Answer: C

For GET and DELETE requests (when there's no content in the request body), the signing string must include at least these headers: (request-target) (as described in draft-cavage-http-signatures-08) host date or x-date (if both are included, Oracle uses x-date)

Correct Answer: C

Canary deployments are a pattern for rolling out releases to a subset of users or servers. The idea is to first deploy the change to a small subset of servers, test it, and then roll the change out to the rest of the servers. The canary deployment serves as an early warning indicator with less impact on downtime: if the canary deployment fails, the rest of the servers aren't impacted. Blue-green deployment is a technique that reduces downtime and risk by running two identical production environments called Blue and Green. At any time, only one of the environments is live, with the live environment serving all production traffic. For this example, Blue is currently live and Green is idle. A/B testing is a way to compare two versions of a single variable, typically by testing a subject's response to variant A against variant B, and determining which of the two variants is more effective A rolling update offers a way to deploy the new version of your application gradually across your cluster.
