NEW QUESTION # 23
Challenge 2
In deploying a new application, a cloud customer needs to reflect different security postures. If a security zone is enabled with the Maximum Security Zone recipe, the customer will be unable to create or update a resource in the security zone if the action violates the attached Maximum Security Zone policy.
As an application requirement, the customer requires a compute instance in the public subnet. You therefore, need to configure Custom Security Zones that allow the creation of compute instances in the public subnet.
Review the architecture diagram, which outlines the resoures you'll need to address the requirement:
Preconfigured
To complete this requirement, you are provided with the following:
Access to an OCI tenancy, an assigned compartment, and OCI credentials
Required IAM policies

Explanation:
To provision a compute instance named IAD-SP-PBT-1-VM-01 in the IAD-SP-PBT-PUBSNET-01 public subnet with the specified configuration (Oracle Linux 8 image, VM Standard A1 Flex shape), follow these steps based on the Oracle Cloud Infrastructure (OCI) Compute documentation.
Step-by-Step Solution for Task 5: Provision a Compute Instance
* 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 Compute Instances:
* From the OCI Console, click the navigation menu (hamburger icon) on the top left.
* UnderCompute, selectInstances.
* Create a New Compute Instance:
* Click theCreate Instancebutton.
* Configure the Instance Details:
* Name:Enter IAD-SP-PBT-1-VM-01.
* Compartment:Select the assigned compartment.
* Placement:Choose the availability domain (e.g., AD-1) based on your region's availability.
* Select the Image:
* UnderImage and Shape, clickChange Image.
* SelectOracle Linux 8from the platform images list.
* ClickSelect Image.
* Choose the Shape:
* ClickChange Shape.
* SelectVM Standardcategory.
* ChooseA1 Flexfrom the shape options.
* Configure the OCPUs (e.g., 1 OCPU) and memory (e.g., 6 GB) as needed for A1 Flex, then click Select Shape.
* Configure Networking:
* UnderNetworking, ensure theVirtual Cloud Networkis set to IAD-SP-PBT-VCN-01.
* Set theSubnetto IAD-SP-PBT-PUBSNET-01 (public subnet with CIDR 10.0.1.0/24).
* EnableAssign a public IPv4 addressto allow external connectivity.
* Leave the default security list or assign a custom one if configured previously.
* Set Up SSH Access:
* UnderAdd SSH Keys, either:
* Upload your public SSH key file, or
* Paste your public SSH key manually.
* This ensures you can access the instance via SSH.
* Launch the Instance:
* ClickCreateto provision the compute instance.
* Wait for the instance to reach theRunningstate (this may take a few minutes).

* Once the instance is running, go to the instance details page for IAD-SP-PBT-1-VM-01.
* Copy theOCIDdisplayed (e.g., ocid1.instance.oc1..<unique_string>).
OCID of the Created Compute Instance
* Enter the OCID of the created compute instance (IAD-SP-PBT-1-VM-01) into the text box. The exact OCID will be available after Step 9 (e.g., ocid1.instance.oc1..<unique_string>).
Notes
* Ensure the security zone IAD_SAP-PBT-CSZ-01 and its associated recipe IAD-SP-PBT-CSP-01 allow compute instance creation in the public subnet (10.0.1.0/24).
* Verify network connectivity by testing SSH access using the public IP assigned to the instance.
NEW QUESTION # 24
In Oracle Cloud Infrastructure (OCI), bare metal instances provide customers with direct access to the underlying hardware. To mitigate security risks when a customer terminates a bare metal instance, OCI utilizes Root-of-Trust hardware.
What is the primary function of the Root-of-Trust hardware in this context?
- A. It ensures all non-volatile memory on the terminated instance is securely wiped before reuse.
- B. It guarantees complete isolation between customer workloads on different instances.
- C. It eliminates the need for hypervisors, reducing the potential attack surface.
- D. It automatically encrypts data at rest on the bare metal instance.
Answer: A

Task 7: Verify the OCI Certificate with Load Balancer
Verify HTTPS connection to the load balancer by running the following command in Cloud Shell curl -k https://<Public IP of PBT-CERT-LB-01> Enter the following URL in the web browser:
https://<Public IP of PBT-CERT-LB-01>
If prompted with a certificate error, accept the risk and continue.
Verify web page content by ensuring the text, "You are visiting Web Server 1" from the index.html file is displayed in the browser See the solution below in Explanation.
Answer:
Explanation:
Task 7: Verify the OCI Certificate with Load Balancer
Step 1: Obtain the Public IP of the Load Balancer
* Log in to the OCI Console.
* Navigate toNetworking>Load Balancers.
* Click on PBT-CERT-LB-01.
* Note thePublic IP Addressfrom the load balancer details page.
Step 2: Verify HTTPS Connection Using Cloud Shell
* Open the OCI Cloud Shell from the top-right corner of the OCI Console.
* Run the following command, replacing <Public IP of PBT-CERT-LB-01> with the public IP you noted:
curl -k https://<Public IP of PBT-CERT-LB-01>
* Expected output: You should see the text "You are visiting Web Server 1" if the connection is successful. The -k flag ignores certificate validation errors (common during initial testing with self- signed or newly issued certificates).
* If you encounter an error, ensure the load balancer is active, the listener is configured correctly, and the backend server (PBT-CERT-VM-01) is reachable.
Step 3: Verify in a Web Browser
* Open a web browser.
* Enter the following URL, replacing <Public IP of PBT-CERT-LB-01> with the public IP you noted:
https://<Public IP of PBT-CERT-LB-01>
* If prompted with a certificate warning (e.g., due to a self-signed certificate or untrusted CA), accept the risk and proceed (click "Advanced" and "Proceed" or similar, depending on your browser).
* Verify that the web page displays the text "You are visiting Web Server 1" from the index.html file created on PBT-CERT-VM-01.
Step 4: Troubleshoot (if needed)
* If the text is not displayed:
* Check the load balancer health status underBackend Sets>Healthin the OCI Console.
* Ensure the security list PBT-CERT-LB-SL-01 allows port 443 and the compute instance security list allows port 80.
* Verify the Apache service is running on PBT-CERT-VM-01 by SSHing in and running sudo systemctl status httpd.
