You are asked to deploy a new application that has been designed to scale horizontally. The business stakeholders have asked that the application be deployed In us-phoenlx-1. Normal usage requires 2 OCPUs. You expect to have few spikes during the week, that will require up to 4 OCPUs, and a major usage uptick at the end of each month that will require 8 OCPUs. What is the most cost-effective approach to implement a highly available and scalable solution?

  1. Create an instance pool with a VM.Standard2.2 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances, to handle the weekly spikes, and a maximum of 4 Instances.
  2. Create an instance with 1 OCPU shape. Use a CLI script to clone It when more resources are needed.
  3. Create an instance pool with a VM.Standard2.1 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances and a maximum of 8 instances.
  4. Create an instance with 1 OCPU shape. Use the Resize Instance action to scale up to a larger shape when more resources are needed.

Answer(s): A

Explanation:

Instance pools let you provision and create multiple Compute instances based off the same instance configuration, within the same region. They also enable integration with other services, such as the Load Balancing service and IAM service, making it easier to manage groups of instances You create an instance pool using an existing instance configuration. You can automatically adjust the number of instances in an instance pool based on performance metrics such as CPU utilization.
Autoscaling lets you automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.

Which two statements accurately describe Ansible Modules for Oracle Cloud Infrastructure (OCI)?

  1. OCI Ansible Modules represent discrete provisioning tasks or operations that you can not invoke individually from the command line, or else run individually or In sequence from a playbook.
  2. OCI Ansible Modules are units of organization that allows you to abstract configuration, orchestration, and provisioning tasks into roles that you can save and share among playbooks and other users.
  3. OCI Ansible Modules represent discrete provisioning tasks or operations that you can invoke individually from the command line, or else run Individually or in sequence from a playbook.
  4. OCI Ansible Modules enable orchestrating, provisioning, and configuration management tasks on Oracle Cloud Infrastructure.
  5. OCI Ansible Modules is not able to provide you state control of resources.

Answer(s): A,D

Explanation:

Oracle supports the use of Ansible for cloud infrastructure provisioning, orchestration, and configuration management. Ansible allows you to automate configuring and provisioning your cloud infrastructure, deploying and updating software assets, and orchestrating your complex operational processes.
What enables orchestrating, provisioning, and configuration management tasks are the Ansible modules for Oracle Cloud Infrastructure. Ansible provides a library of these Ansible modules "out of the box" for managing common tasks, and libraries of custom modules from cloud providers like AWS and Azure. Oracle also provides a library of Ansible cloud modules that support provisioning and managing Oracle Cloud Infrastructure service
Ansible Modules represent discrete provisioning tasks or operations that you can invoke individually from the command line, or else run individually or in sequence from a playbook Ansible roles are units of organization that allows you to abstract configuration, orchestration, and provisioning tasks into roles that you can save and share among playbooks and other users, and that are useful for organizing functionality in playbooks

Your company has restructured its HR departments. As part of this change, you also need to re- organize compartments within Oracle Cloud Infrastructure (OCI) to align them to the company's new organizational structure. The following change is required:
Comportment Team_x needs to be moved under a new parent compartment, Project_B



The tenancy has the following policies defined for compartments Project_A and Project_B:
Policy1 Allow group G1 to manage instance-family in compartment HR:Project_A Policy2 Allow group G2 to manage instance-family in compartment HR:Project_B Which two statements describe the impacts after the compartment Team_x is moved?

  1. Group G2 can now manage instance-families in compartment Project_B compartment Project_A and compartment Team_x
  2. Group G1 can now manage instance-families in compartment Project_A but not in compartment Team_x
  3. Group G1 can now manage instance-families in compartment project_A,compartment project_B and compartment Team_x
  4. Group G2 can now manage instance-families in compartment Project_B and compartment Team_x
  5. Group G2 can now manage instance-families in compartment Project_A but not in compartment Team_x

Answer(s): B,D

Explanation:

Understanding the Policy Implications When You Move a Compartment After you move a compartment to a new parent compartment, the access policies of the new parent take effect and the policies of the previous parent no longer apply. Before you move a compartment, ensure that:
- You are aware of the policies that govern access to the compartment in its current position.

- You are aware of the polices in the new parent compartment that will take effect when you move the compartment.
Groups with Permissions in the Current Compartment Lose Access; Groups with Permissions in the Destination Compartment Gain Access



You have a Linux compute Instance located in a public subnet in a VCN which hosts a web application. The security list attached to subnet containing the compute Instance has the following stateful Ingress rule.



Which step will resolve the issue?

  1. In the route table, add a rule for your default traffic to be routed to service gateway.
  2. In the security list, add an ingress rule for port 80 (http).
  3. In the security list, remove the ssh rule.
  4. In the route table, add a rule for your default traffic to be routed to NAT gateway.

Answer(s): B

Explanation:

Add stateful ingress rule to receive and respond to HTTP traffic. Example: Instance A and Host B are communicating (Host B could be any host, whether an instance or not). The stateful ingress rule allows traffic from any source IP address (0.0.0.0/0) to destination port 80 only (TCP protocol). No egress rule is required to allow the response traffic.



Your team Implemented a SaaS application that requires a whole system deployment for each new customer. The Infrastructure provisioning is already automated via Terraform, and now you have been asked to develop an Ansible playbook to centralize configuration file management and deployment.
What Is the most effective way to ensure your playbooks are utilizing up-to-date and accurate Inventory?

  1. Implement a Command Line Interface script to list all the resources and run it within Ansible to generate a dynamic inventory list.
  2. Export an inventory list using Terraform apply command.
  3. Export an inventory list from the Oracle Cloud Infrastructure Web console.
  4. Download the dynamic inventory script provided by Oracle Cloud Infrastructure and include It in the playbook Invocation command.

Answer(s): D

Explanation:

Ansible tracks configuration resources by preserving lists, called inventory lists. These inventory files can be either simple static lists, or they can be dynamic lists that automatically update when inventory resources are added, deleted, or moved.
When using Ansible to work with hosts that you have provisioned in Oracle Cloud Infrastructure, static inventory lists can cause problems because Compute instances are added and deleted over time. They can also be affected by external tools such as Terraform, or by the Oracle Cloud Infrastructure SDKs.
Oracle Cloud Infrastructure provides two tools for working with Ansible inventory: a dynamic inventory plugin (recommended) and a dynamic inventory script.
Using the Dynamic Inventory Script
Having up-to-date and accurate inventory lists is essential for running Ansible playbooks. Oracle
Cloud Infrastructure provides you with a script that you can download and run to ensure that your instance inventory list is always up-to-date. The script ensures that you always have the current set of Oracle Cloud Infrastructure compute instances available to your playbooks https://docs.cloud.oracle.com/en-us/iaas/Content/API/SDKDocs/ansibleinventoryscript.htm
