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
正解：
See the solution below with Step by Step Explanation
Explanation:
Task 1: Create a Bucket in Object Storage
Create a bucket named CloudOpsBucket_<user id> with the following properties:
Storage tier: Standard
Auto-tiering: Disabled
Object versioning: Enabled
Emit events: Disabled
Keys: Oracle-managed
Visibility: Private
Task 2: Upload a Directory's Contents to Object Storage
Upload the contents of the directory ~/dir_to_upload and its subdirectories to the bucket CloudOpsBucket Task 3: Add a Lifecycle Policy to the Bucket Create a lifecycle policy rule that deletes all files from ~/dir_to_upload/temp after 30 days Task 1: Create a bucket in Object Storage
1. Open Cloud Shell in the console. Under Network along the top, select Ephemeral Private Network Setup.
2. Select the subnet of the compute instance.
3. SSH into the compute instance using the provided SSH key:
ssh -i /path/to/key opc@<private_ip>
4. In the compute instance, create the bucket with the following command (note that it's one long line):
oci os bucket create -c "<compartment_id>" --name "CloudOpsBucket" --auth instance_principal --versioning 'Enabled' Task 2: Upload a directory's contents to Object Storage
1. Upload the contents of the specified directory and subdirectories with the following command (note that it's one long line):
oci os object bulk-upload -bn "CloudOpsBucket" --src-dir "~/dir_to_upload" --auth instance_principal Task 3: Add a lifecycle policy to the bucket
1. Create a file named rule.json
2. Add the following content to rule.json:
{"items": [{"action": "DELETE","is-enabled": true,"name": "Delete-Rule","object-name-filter": {"exclusion-patterns": null,"inclusion-patterns": null,"inclusion-prefixes": ["temp/"]},"target": "objects","time-amount": 30,"time-unit": "DAYS"}]}
3. Add the lifecycle policy rule with the following command:
oci os object-lifecycle-policy put -bn "CloudOpsBucket" --from-json file://rule.json --auth instance_principal Top of Form
You use a bucket in Object Storage to store backups of a database. Versioning is enabled on these objects, so that every time you take a new backup, it creates a new version. You add the following life-cycle policy rule: { "action": "DELETE", "is-enabled": true, "name": "Delete-Rule", "object-name-filter": null, "target": "objects", "time-amount": 60, "time-unit": "DAYS" } Which option is true regarding this rule?

As a cloud operations engineer responsible for a Rails application on multiple compute instances in an OCI subnet your database team recently provided you with a new config/database. yml file to direct Rails to use a new database back end. You need to update this file on each compute instance and restart Rails in a rolling fashion.
Which tool is best suited for this task?

When you provision a compute instance in Oracle Cloud Infrastructure (OCI), you can provide data to cloud-init on the instance. This data is referred to as "user data" by cloud-init. and can be written in various formats that cloud-init can read.
Which two file formats can be used to write user data with cloud- init?

You have recently joined a startup company and quickly find that nobody is tracking the amount of money spent on Oracle Cloud Infrastructure (OCI). Seeing an opportunity to help save money you begin creating a solution to better track the cost of resources provisioned by each individual on the team. Which option allows you to identify excessive spend across all re-sources in your tenancy? (Choose the best answer.)

A company is developing a highly available web application, which will be hosted on Oracle Cloud Infrastructure (OCI). For high reliability, the Load Balancer's health status is very important. Which of the following may lead to an unhealthy Load Balancer?

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-phoenix-1. Nor-mal 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? (Choose the best answer.)

You have been asked to set up connectivity between a client on-premises network and Oracle Cloud Infrastructure (OCI). The requirements are:
* Low latency: The applications are financial and require low latency connectivity into OCI. * Consistency: The application is not tolerant of performance variation.
* Performance: The communications link needs to support up to 1.25 Gbps.
* Encryption: The communications link needs to encrypt any data in transit between the on-premises network and OCI Virtual Cloud Network (VCN). The client wants to implement the above with as low a cost as possible, while meeting all of the requirements. What should you suggest? (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.)

Here is a partial code from a Terraform template written for Oracle Cloud Infrastructure (OCI):

What operation(s) does it perform? (Choose the best answer.)
