Challenge 1 - Task 4 of 5

Authorize OCI Resources to Retrieve the Secret from the Vault

Scenario

You are working on a Python program running on a compute instance that needs to access an external service. To access the external service, the program needs credentials (password). Given that it is not a best security practice, you decide not to hard code the credential in the program. Instead, you store the password (secret) in a vault using the OCI Vault service. The requirement now is to authorize the compute instance so that the Python program can retrieve the password (secret) by making an API call to the OCI Vault.

Preconfigured

To complete this requirement, you are provided with:

• An OCI Vault to store the secret required by the program, which is created in the root compartment as PBT_Vault_SP.
• An instance principal IAM service, which enables instances to be authorized actors (principals) that can retrieve the secret from the OCI Vault.
• A dynamic group named PBT_Dynamic_Group_SP with permissions to access the OCI Vault. This dynamic group includes all of the instances in your compartment.
• Access to Cloud Shell.
• Permissions to perform only the tasks within the challenge.

Note: You are provided with access to an OCI Tenancy, an assigned compartment, and OCI credentials. Throughout your exam, ensure to use the assigned Compartment 99234021-C01 and Region us-ashburn-1.

Complete the following tasks in the OCI environment provisioned:

• Create a Linux Instance with the name [Provide Name Here] within the compartment.

Provide your own public key to SSH the instance.

Complete the following tasks in the OCI environment provisioned:

• Create Master Encryption Key with the name my_pbt_msk with 256 bits shape.
• Create a Secret with the name my-pbt-secret_99234021-lab.user01 and secret content.

For example: If your user name is 99346163-lab.user02, then the secret should be named as my-pbt-secret_99346163-lab.user02.

Challenge 3 - Task 1 of 4

Set Up a Bastion Host to Access the Compute Instance in a Private Subnet Scenario

A compute instance is provisioned in a private subnet that is not accessible through the Internet. To access the compute instance resource in a private subnet, you must provide a time-bound SSH session without deploying and maintaining a public subnet and a jump server, which eliminates the hassle and potential attack surface from remote access.

To complete this deployment, you have to perform the following tasks in the environment provisioned for you:

• Configure a Virtual Cloud Network (VCN) and a Private Subnet.

• Provision a Compute Instance in the private subnet and enable Bastion Plugin.

• Create a Bastion and Bastion session.

• Connect to a compute instance using Managed SSH session.

Note: You are provided with access to an OCI Tenancy, an assigned compartment, and OCI credentials. Throughout your exam, ensure to use the assigned Compartment 99233424-C01 and Region us-ashburn-1

Complete the following tasks in the provisioned OCI environment:

• Create a Virtual Cloud Network (VCN) with the name PBT-BAS-VCN-01
• Create a Private Subnet with the name PBT-BAS-SNET-01
• Create a Service Gateway with the name PBT-BAS-SG-01, using the service "All IAD Services in Oracle Services Network"
• Add Route Rules for Service Gateway
