Which Oracle Cloud Infrastructure (OCI) service is best suited for running serverless apps?

  1. Oracle Functions
  2. Virtual Cloud Network
  3. Streaming
  4. Audit

Answer(s): A

Explanation:

Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a- Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs. 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. Oracle Functions is based on Fn Project. Fn Project is an open source, container native, serverless platform that can be run anywhere - any cloud or on-premises. Fn Project is easy to use, extensible, and performant. You can download and install the open source distribution of Fn Project, develop and test a function locally, and then use the same tooling to deploy that function to Oracle Functions. You can access Oracle Functions using the Console, a CLI, and a REST API. You can invoke the functions you deploy to Oracle Functions using the CLI or by making signed HTTP requests.

What does compute instance horizonal scaling mean?

  1. stopping/starting the instance
  2. backing up data to object storage
  3. adding additional compute instances
  4. changing compute instance size

Answer(s): C

Explanation:

Cloud Horizontal Scaling refers to provisioning additional servers to meet your needs, often splitting workloads between servers to limit the number of requests any individual server is getting. In a cloud-based environment, this would mean adding additional instances instead of moving to a larger instance size.
Cloud Vertical Scaling refers to adding more CPU or memory to an existing server, or replacing one server with a more powerful server.


Reference:

Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.

An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.



With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool -- Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and comes with an upper limit.

OCI budgets can be set on which two options?

  1. Cost-tracking tags
  2. Free-form tags
  3. Compartments
  4. Virtual Cloud Network
  5. Tenancy

Answer(s): A,C

Explanation:

In OCI a budget can be used to set soft limits on your Oracle Cloud Infrastructure spending. You can set alerts on your budget to let you know when you might exceed your budget, and you can view all of your budgets and spending from one single place in the Oracle Cloud Infrastructure console.
Budgets are set on
- Cost-tracking tags
- Compartments (including the root compartment)


Reference:

https://docs.cloud.oracle.com/en-us/iaas/Content/Billing/Concepts/budgetsoverview.htm



you are analyzing your Oracle Cloud Infrastructure (OCI) usage with Cost Analysis tool in OCI Console.
Which is not a default feature of the tool?

  1. Filter costs by applications
  2. Filter costs by compartments
  3. Filter costs by tags
  4. Filter costs by date

Answer(s): A

Explanation:

You can filter Costs Analysis Tools by following three ways To filter costs by dates
To filter costs by tags
To filter costs by compartments
