Scenario: 2 (Oracle Cloud-init and AutoScaling: Use cloud-init to Configure Apache on Instances in an Autoscaling Instance Pool)
Scenario Description: (Hands-On Performance Exam Certification)
You're deploying an Apache-based web application on OCI that requires horizontal autoscaling.
To configure instances upon provisioning, write a cloud-init script for Oracle Linux 8 that installs and enables Apache (httpd), and opens the firewall for HTTP on TCP port 80. Create an instance configuration and include the cloud-init script in it. Use this instance configuration to create an instance pool and autoscaling configuration.
Pre-Configuration:
To fulfill this requirement, you are provided with the following:
Access to an OCI tenancy, an assigned compartment, and OCI credentials
A VCN Cloud-Init Challenge VCN with an Internet gateway and a public subnet. The security list for the subnet allows ingress via TCP ports 22 and 80 (SSH and HTTP). The route table forwards all egress to the Internet gateway.
Access to the OCI Console
Required IAM policies
An SSH key pair for the compute instance
Public Key https://objectstorage.us-ashburn-1.oraclecloud.com/n/tenancyname/b/PBT_Storage/o/PublicKey.pub
Private Key https://objectstorage.us-ashburn-1.oraclecloud.com/n/tenancyname/b/PBT_Storage/o/PKey.key
Note: Throughout your exam, ensure to use assigned Compartment , User Name , and Region.
Complete the following tasks in the provisioned OCI environment:
Task 1(a): Develop the cloud-init Script:
Task 1(b): Use cloud-init to Configure Apache on Instances in an Autoscaling Instance Pool:
Scenario: 3 (Use the OCI CLI to Work with Object Storage from a Compute Instance)
Scenario Description: (Hands-On Performance Exam Certification)
Your company runs a web application in OCI that generates log files. You want to upload these files to OCI Object Storage to meet data retention requirements. Some files need to be retained indefinitely, whereas others can be deleted after 30 days. Use the OCI CLI to create bucket and upload the log directory and create a lifecycle policy rule to delete temporary files after 30 days.
Pre-Configuration:
To fulfill this requirement, you are provided with the following:
Access to an OCI tenancy, an assigned compartment, and OCI credentials
A compute instance with OCI CLI installed and a set of files in ~/dir_to_upload to use
Access to the OCI Console
Required IAM policies
Assumptions:
Perform the tasks by using the OCI CLI on the compute instance.
Use instance principal authentication for all CLI commands; the instance has been given the policies necessary.
Connect to the compute instance using Cloud Shell’s private networking and the provided SSH key.
An SSH key pair has been provided to you for the compute instance.
Private Key https://objectstorage.us-ashburn- 1.oraclecloud.com/n/tenancyname/b/PBT_Storage/o/PKey.key
Note: Throughout your exam, ensure to use assigned Compartment , User Name and Region.
Complete the following tasks in the provisioned OCI environment:
Task 1: Create a Bucket in Object Storage
Task 2: Upload a Directory’s Contents to Object Storage
Task 3: Add a Lifecycle Policy to the Bucket
Scenario: 4 (Write Identity and Access Management Policies to Secure a Tenancy)
Scenario Description: (Hands-On Performance Exam Certification)
Your company has signed up for an OCI tenancy to migrate an e-commerce application, a supply chain management (SCM) system, and a customer relationship management (CRM) system. You have been tasked with setting up the requisite identity and access management (IAM) policies for your team to begin developing on OCI.
You start by setting up the following compartment hierarchy:
Tenancy (root)
Common-Infra
Network
Security
Applications
E-Comm
SCM
CRM
You create the following groups:
Network-Admins
Security-Admins
E-Comm-Admins
SCM-Admins
CRM-Admins
Write the IAM policies for the following use cases:
Assumptions:
Assume that all policies will be attached to the root compartment.
Write one policy per given text box.
Keep policies as simple as possible by using verbs instead of permissions (for example, “inspect orm-stacks” instead of “ORM_STACK_INSPECT”) and aggregate resource types instead of individual ones (for example, “file-family” instead of “file-systems” and “mount-targets”)
Task 1
Write a policy statement to enable Network-Admins to create and destroy network-related resources, such as VCNs, subnets, gateways, and so on in the Network compartment.
Task 2
Write policy statements to enable E-Comm-Admins to provision and destroy compute instances in the E-Comm compartment by using networking resources in the Network compartment.[Write one policy per given text box]
Task 3
Write a policy statement to enable SCM-Admins to provision, destroy, and back up block volumes in the SCM compartment—but only in Phoenix and London.
Scenario: 1 (Create a reusable VCN Configuration with Terraform)
Scenario Description: (Hands-On Performance Exam Certification)
You’ll launch and destroy a VCN and subnet by creating Terraform automation scripts and issuing commands in Code Editor. Next, you’ll download those Terraform scripts and create a stack by uploading them into Oracle Cloud Infrastructure Resource Manager.
You’ll then use that service to launch and destroy the same VCN and subnet.
In this scenario, you will:
a. Create a Terraform folder and file in Code Editor.
b. Create and destroy a VCN using Terraform.
c. Create and destroy a VCN using Resource Manager.
Which two statements about the Oracle Cloud Infrastructure (OCI) Command Line Inter-face (CLI) are TRUE? (Choose two.)
You have been contracted by a local e-commerce company to assist with enhancing their online shopping application. The application is currently deployed in a single Oracle Cloud Infrastructure (OCI) region. The application utilizes a public load balancer, application servers in a private subnet, and a database in a separate, private subnet. The company would like to deploy another set of similar infrastructure in a different OCI region that will act as standby site. In the event of a failure at the primary site, all customers should be routed to the failover site automatically. After deploying the additional infrastructure within the second region, how should you configure automated failover requirements? (Choose the best answer.)
You have a group pf developers who launch multiple VM.Standard2.2 compute instances every day into the compartment Dev. As a result, your OCI tenancy quickly hit the service limit for this shape. Other groups can no longer create new instances using VM.Standard2.2 shape. Because of this, your company has issued a new mandate that the Dev compartment must include a quota to allow for use of only 20 VM.Standard2.2 shapes per Availability Do-main. Your solution should not affect any other compartment in the tenancy. Which quota statement should be used to implement this new requirement? (Choose the best answer.)
Which statement about Oracle Cloud Infrastructure paravirtualized block volume attachments is TRUE? (Choose the best answer.)
You have a group of developers who launch multiple VM.Standard3.Flex compute in-stances every day into the compartment Dev. As a result, your Oracle Cloud Infrastructure (OCI) tenancy quickly hits the service limit for this shape, and other groups can no longer create new instances using the VM.Standard3.Flex shape. Therefore, your company issues a new mandate that the Dev compartment must include a quota that allows the use of only 20 VM.Standard3.Flex OCPUs per availability domain, without affecting any other compartment in the tenancy. Which quota statement would you use to implement this new requirement?
The boot volume on your Oracle Linux instance has run out of space. Your application has crashed due to a lack of swap space, forcing you to increase the size of the boot volume. Which step should NOT be included in the process used to solve the issue? (Choose the best answer.)
