Oracle Cloud Infrastructure 2025 Cloud Ops Professional : 1Z0-1067-25

You have a web application that is running on compute instances distributed across an availability domain's fault domains. To share state, instances of the application need to read and write to a shared file system that supports concurrent access from multiple instances.
Which two can help fulfill this technical requirement?

• A. Attach a single block volume in read/write shared mode to alt the instances. Use a cluster aware system such as Oracle Cluster File System version 2 (OCFS2) to coordinate access to the shared volume.
• B. Attach a block volume to each instance. Enable replication between the block volumes.
• C. Attach a single block volume in read/write shared mode to all the instances. Enable the cluster plug-in on the Oracle Cloud Agent to coordinate access to the shared volume.
• D. Create a file system in the File Storage service. Create a mount target and export the file system. Mount the export onto all of the instances.

SIMULATION
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

You run a large global application with 90% of customers based in the US and Canad a. You want to be able to test a new feature and allow a small percentage of users to access the new version of your application. What Oracle Cloud Infrastructure Traffic Management steering policy should you utilize? (Choose the best answer.)

• A. Geolocation steering
• B. IP Prefix steering
• C. Load Balancer
• D. ASN steering

You have recently been asked to take over management of your company infrastructure provisioning efforts, utilizing Terraform v0.12 to provision and manage infrastructure resources in Oracle Cloud Infrastructure (OCI).
For the past few days the development environments have been failing to provision. Terraform re-turns the following error:


You locate the related code block in the Terraform config and find the following:
Which correction should you make to solve this issue? (Choose the best answer.)

• A. Modify line 15 to be the following: tcp_options = {min = 22, max =22)
• B. Place a command at the end of line 16
• C. Replace the curly braces { } in lines 11 and 16 with square braces [ ]
• D. Modify line 15 to be the following: tcp_options { min = 22 max =22 }

You created an Oracle Linux compute instance through the Oracle Cloud Infrastructure (OCI) management console then immediately realize you forgot to add an SSH key file. You notice that OCI compute service provides instance console connections that supports adding SSH keys for a running instance. Hence, you created the console connection for your Linux server and activated it using the connection string provided. However, now you get prompted for a username and password to login. What option should you recommend to add the SSH key to your running instance, while minimizing the administrative overhead? (Choose the best answer.)

• A. You need to configure the boot loader to use ttyS0 as a console terminal on the VM.
• B. You need to reboot the instance from the console, boot into the bash shell in maintenance mode, and add SSH keys for the OPC user.
• C. You need to terminate the running instance and recreate it by providing the SSH key file.
• D. You need to modify the serial console connection string to include the identity file flag, to specify the SSH key to use.
