Oracle 1z0-1104-25 - Oracle Cloud Infrastructure 2025 Security Professional

Since I can’t create resources or retrieve OCIDs directly in your OCI environment, I’ll provide a step-by-step solution based on verified OCI documentation and best practices as of 02:30 PM BST on Thursday, June 12, 2025. Follow these instructions precisely in the OCI Console or CLI, using the preconfigured PBI_Vault_SP vault and the PBT-CERT-CA-01 Certificate Authority created in the previous task. Replace with your actual username (e.g., 99008677-lab.user01), ensuring special characters are removed.

Task 5: Create a Certificate

Step 1: Access the OCI Vault

Log in to the OCI Console.

Navigate toIdentity & Security>Vault.

Select the root compartment.

Locate and click on the vault named PBI_Vault_SP.

Step 2: Create the Certificate

In the PBI_Vault_SP vault details page, underResources, clickCertificates.

ClickCreate Certificate.

Enter the following details:

Name: Replace with your username (e.g., if your username is 99008677-lab.user01, remove special characters like - and . to get 99008677labuser01, then use PBT-CERT-0199008677labuser01).

Common Name: Enter PBT-CERT-OCICERT-01.

Certificate Authority: Select the PBT-CERT-CA-01 CA created in Task 4 (e.g., PBT-CERT-CA-0199008677labuser01).

Subject: Leave as default or adjust (e.g., Organization, Country) if required.

Validity Period: Set as needed (e.g., 1 year), or use the default.

Compartment: Ensure it’s set to the root compartment.

ClickCreate Certificateand wait for the certificate to be issued.

Step 3: Verify the Certificate

After creation, go to theCertificatessection under PBI_Vault_SP.

Confirm the certificate PBT-CERT-01 (e.g., PBT-CERT-0199008677labuser01) is listed and its status is active.

Task 3: Create a Master Encryption Key

Step 1: Access the OCI Vault

Log in to the OCI Console.

Navigate toIdentity & Security>Vault.

Select the root compartment.

Locate and click on the vault named PBI_Vault_SP.

Step 2: Create the Master Encryption Key

In the PBI_Vault_SP vault details page, underResources, clickKeys.

Enter the copied OCID exactly as it appears into the provided text box.

Task 4: Create a Certificate Authority (CA)

Create a certificate authority, where:

CA name: PBT-CERT-CA-01-

For example, if your username is 99008677-lab.user01, then the certificate authority name should be PBT-CERT-CA-01990086771abuser01

Ensure you eliminate special characters from the user name.

Common name: PBT-CERT-OCICA-01

Master Encryption Key: PBT-CERT-MEK-01 (created in the previous task)

Answer: See the solution below in Explanation.

Task 4: Create a Certificate Authority (CA)

Validity Period: Set as needed (e.g., 10 years), or use the default.

Compartment: Ensure it’s set to the root compartment.

ClickCreate Certificate Authorityand wait for the CA to be provisioned.

Step 3: Verify the Certificate Authority

After creation, go to theCertificate Authoritiessection under PBI_Vault_SP.

Confirm the CA PBT-CERT-CA-01 (e.g., PBT-CERT-CA-0199008677labuser01) is listed and its status is active.

To create a Security Zone named IAD_SAP-PBT-CSZ-01 in your assigned compartment and associate it with the Custom Security Zone Recipe IAD-SP-PBT-CSP-01 created in the previous task, follow these steps based on the Oracle Cloud Infrastructure (OCI) Security Zones documentation.

Step-by-Step Solution for Task 2: Create a Security Zone

Log in to the OCI Console:

Use your OCI credentials to log in to the OCI Console (https://console.us-ashburn-1.oraclecloud.com ).

Ensure you have access to the assigned compartment.

Navigate to Security Zones:

From the OCI Console, click the navigation menu (hamburger icon) on the top left.

UnderGovernance and Administration, selectSecurity Zones.

Create a New Security Zone:

In the Security Zones dashboard, click theCreate Security Zonebutton.

Configure the Security Zone Details:

Name:Enter IAD_SAP-PBT-CSZ-01.

Compartment:Select the assigned compartment provided.

Description:(Optional) Add a description, e.g., "Security Zone for public subnet compute instances."

Associate the Custom Security Zone Recipe:

In theRecipesection, select the custom recipe IAD-SP-PBT-CSP-01 created in Task 1 from the dropdown list.

Ensure the recipe is correctly associated to enforce the policy allowing compute instances in the public subnet.

Define the Security Zone Scope:

UnderResources to Protect, select the compartment or specific resources (e.g., the VCN with CIDR 10.0.0.0/16 and public subnet 10.0.10.0/24) to apply the security zone.

Check the box to include all resources in the selected compartment if applicable.

Create the Security Zone:

ClickCreateto finalize the security zone creation.

Once created, note theOCIDof the security zone from the security zone details page. The OCID will be a unique identifier starting with ocid1.securityzone.

Verify the Security Zone:

Go to theSecurity Zonestab and locate IAD_SAP-PBT-CSZ-01.

Confirm the associated recipe (IAD-SP-PBT-CSP-01) and the applied policies.

OCID of the Created Security Zone

The exact OCID will be generated upon creation (e.g., ocid1.securityzone.oc1..). Please enter the OCID displayed in the OCI Console after completing Step 7.
