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:
(CHK) Your company recently adopted a hybrid cloud architecture which requires them to migrate some of their on-premises web applications to Oracle Cloud Infrastructure (OCI). You created a Terraform template which automatically provisions OCI resources such as compute instances, load balancer, and a database instance. After running the stack using the terraform apply command, it successfully launched the compute instances and the load balancer, but it failed to create a new database instance with the following error: Service error: NotAuthorizedOrNotFound. shape VM.Standard2.4 not found. http status code: 404 You dis-covered that the resource quotas assigned to your compartment prevent you from using VM.Standard2.4 instance shapes available in your tenancy. You edit the Terraform script and replace the shape with VM.Standard2.2 Which option would you recommend to re-run the terraform command to have required OCI resources provisioned with the least effort? (Choose the best answer.)
Security Testing Policy describes when and how you may conduct certain types of security testing of Oracle Cloud Services, including vulnerability and penetration tests, as well as tests involving data scraping tools. What does Oracle allow as part of this testing? (Choose the best answer.)
Your application is using an Object Storage bucket named app-data in the namespace vision, to store both persistent and temporary data. Every week all the temporary data should be deleted to limit the storage consumption. Currently you need to navigate to the Object Storage page using the web console, select the appropriate bucket to view all the objects and delete the temporary ones. To simplify the task you have configured the application to save all the temporary data with /temp prefix. You have also decided to use the Command Line Interface (CLI) to perform this operation. What is the command you should use to speed up the data cleanup? (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.)
You set up a bastion host in your VCN to only allow your IP address (140.19.2.140) to establish SSH connections to your Compute Instances that are deployed in a private subnet. The Compute Instances have an attached Network Security Group with a Source Type: Network Security Group (NSG), Source NSG: NSG-050504. To secure the bastion host, you added the following ingress rules to its Network Security Group:
However, after checking the bastion host logs, you discovered that there are IP addresses other than your own that can access your bastion host. What is the root cause of this issue? (Choose the best answer.)
You are asked to implement the disaster recovery (DR) and business continuity requirements for Oracle Cloud Infrastructure (OCI) Block Volumes. Two OCI regions being used: a primary/source region and a DR/destination region. The requirements are: There should be a copy of data in the destination region to use if a region-wide disaster occurs in the source region ✑ Minimize costs Which design will help you meet these requirements? (Choose the best answer.)
You are working as a Cloud Operations Administrator for your company. They have different Oracle Cloud Infrastructure (OCI) tenancies for development and production work-loads. Each tenancy has resources in two regions uk-london-1 and eu-frankfurt-1. You are asked to manage all resources and to automate all the tasks using OCI Command Line Inter-face (CLI). Which is the most efficient method to manage multiple environments using OCI CLI? (Choose the best answer.)
