Question 1

You're managing an Oracle Cloud Infrastructure (OCI) environment where a public website hosts downloadable assets stored in Object Storage buckets. These buckets need to be publicly accessible for website visitors, but Cloud Guard keeps flagging them as security risks.

How can Cloud Guard be configured to ignore problems specific to public buckets while still ensuring security checks are applied to other resources that require them?

Options:

A public bucket is a security risk, so Cloud Guard will keep detecting it.

Resolve or remediate the problems by making the buckets private.

Dismiss problems associated with those resources.

Fix the baseline by configuring the Conditional groups for the detector.

Question 2

"Your company is building a highly available and secure web application on OCI. Because of increasing malicious web-based attacks, the security team has mandated that web servers should not be exposed directly to the Internet.

How should you architect the solution while ensuring fault tolerance and security?

Options:

Deploy at least three web servers in different fault domains within a public subnet, each with a public IP address. Deploy Web Application Firewall (WAF), and configure an origin for each public IP.

Deploy at least three web servers in different fault domains within a private subnet. Place a public load balancer in a public subnet, but skip WAF configuration.

Deploy at least three web servers in different fault domains within a private subnet. Place a public load balancer in a public subnet and configure a back-end set for all web servers. Deploy Web Application Firewall (WAF) and set the load balancer public IP address as the origin.

Deploy at least three web servers in different fault domains within a public subnet. Use OCI Traffic Management service for DNS-based load balancing."

Task 2: Create a Compute Instance and Install the Web Server

Create a compute instance, where:

Name: PBT-CERT-VM-01

Image: Oracle Linux 8

Shape: VM.Standard.A1.Flex

Subnet: Compute-Subnet-PBT-CERT

Install and configure Apache web server:

Install Apache

sudo yum -y install httpd

Enable and start Apache

sudo systemctl enable httpd

sudo systemctl restart httpd

2. Install and configure Apache web server:

a. Install Apache

sudo yum -y install httpd

b. Enable and start Apache

sudo systemctl enable httpd

sudo systemctl restart httpd

c. Configure firewall to allow HTTP traffic (port 80)

sudo firewall-cmd --permanent --add-port=80/tcp

sudo firewall-cmd --reload

d. Create an index.html file

sudo bash -c 'echo You are visiting Web Server 1 >> /var/www/html/index.html'

Enter the OCID of the created compute instance PBT-CERT-VM-01 in the text box below.

See the solution below in Explanation.

Explanation:

Task 2: Create a Compute Instance and Install the Web Server

Step 1: Create the Compute Instance

Navigate toCompute>Instances.

ClickCreate Instance.

Enter the following details:

Name: PBT-CERT-VM-01

Compartment: Select your assigned compartment.

Placement: Leave as default or select an availability domain (e.g., Availability Domain 1).

Image: ClickChange Image, selectOracle Linux 8, and confirm.

Shape: ClickChange Shape, selectVM.Standard.A1.Flex, and configure:

OCPUs: 1 (or adjust as needed)

Memory: 6 GB (or adjust as needed)

Networking:

Virtual Cloud Network: Select PBT-CERT-VCN-01.

Subnet: Select Compute-Subnet-PBT-CERT.

Leave public IP assignment enabled for internet access.

SSH Key: Provide your public SSH key (upload or paste) for secure access.

ClickCreateand wait for the instance to be provisioned.

Step 2: Connect to the Compute Instance

Once the instance is created, note thePublic IP Addressfrom the instance details page.

Use an SSH client to connect:

Command: ssh -i opc@

Replace with your private key path and with the instance’s public IP.

Step 3: Install and Configure Apache Web Server

Install Apache:

Run: sudo yum -y install httpd

Enable and Start Apache:

Run: sudo systemctl enable httpd

Run: sudo systemctl restart httpd

Configure Firewall to Allow HTTP Traffic (Port 80):

Run: sudo firewall-cmd --permanent --add-port=80/tcp

Run: sudo firewall-cmd --reload

Create an index.html File:

Run: sudo bash -c 'echo "You are visiting Web Server 1" >> /var/www/html/index.html'

Step 4: Verify the Configuration

Open a web browser and enter to ensure the page displays "You are visiting Web Server 1".

If needed, troubleshoot by checking Apache status: sudo systemctl status httpd.

Step 5: Retrieve and Enter the OCID

Go to the instance details page for PBT-CERT-VM-01 underCompute>Instances.

Copy theOCID(a long string starting with ocid1.instance., unique to your tenancy).

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

Notes

These steps are based on OCI Compute documentation and Oracle Linux 8 setup guides.

Ensure the security list PBT-CERT-CS-SL-01 allows inbound traffic on port 22 (SSH) and port 80 (HTTP) if not already configured.

The OCID will be unique to your instance; obtain it from the OCI Console after creation
