Oracle Cloud Infrastructure 2025 Security Professional Sample Questions (Q38-Q43):

NEW QUESTION # 38
During your investigation of a load balancer issue, you discovered that all back-end servers associated with one of the affected listeners were reported as unhealthy. However, when you checked the back-end servers, they seemed to be working just fine.
What might be causing this issue?

A. Misconfigured health check
B. Incorrect subnet configuration
C. Misconfigured security rule
D. Overloaded back-end servers
E. Incorrect DNS configuration

Answer: A

NEW QUESTION # 39
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.

NEW QUESTION # 40
Challenge 2 -Task 1
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
Task 4: Create a Public Subnet
Create a public subnet named IAD-SP-PBT-PUBSNET-01, within the VCN IAD-SP-PBT-VCN-01 use a CIDR block of 10.0.1.0/24 and configure the subnet to use the internet Gateway See the solution below in Explanation.

Answer:

Explanation:
To create a public subnet named IAD-SP-PBT-PUBSNET-01 within the VCN IAD-SP-PBT-VCN-01 using a CIDR block of 10.0.1.0/24 and configure it to use the Internet Gateway, follow these steps based on the Oracle Cloud Infrastructure (OCI) Networking documentation.
Step-by-Step Solution for Task 4: Create a Public Subnet
* 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 Virtual Cloud Networks:
* From the OCI Console, click the navigation menu (hamburger icon) on the top left.
* UnderNetworking, selectVirtual Cloud Networks.
* Select the VCN:
* Locate and click on the VCN named IAD-SP-PBT-VCN-01 created in Task 3.
* UnderResources, selectSubnets.
* Create a New Subnet:
* Click theCreate Subnetbutton.
* Configure the Subnet Details:
* Name:Enter IAD-SP-PBT-PUBSNET-01.
* Compartment:Ensure it is set to the assigned compartment.
* Subnet Type:SelectPublic Subnet.
* CIDR Block:Enter 10.0.1.0/24.
* Route Table:Select the default route table associated with the VCN (ensure it includes a route to the Internet Gateway with destination 0.0.0.0/0).
* Subnet Access:SelectPublic Subnetand ensure the Internet Gateway is associated.
* DHCP Options:Leave as default or customize if required.
* Security List:Use the default security list or create a new one with appropriate ingress/egress rules (e.g., allow TCP port 22 for SSH and all egress traffic).
* Associate the Internet Gateway:
* Verify that the subnet is configured to route traffic through the Internet Gateway. This is automatically handled if you selected the public subnet option and the VCN's route table is correctly set (as configured in Task 3).
* If needed, edit the route table for the subnet to ensure a rule exists:
* Destination CIDR Block:0.0.0.0/0
* Target Type:Internet Gateway
* Target:Select the Internet Gateway associated with IAD-SP-PBT-VCN-01.
* Create the Subnet:
* ClickCreateto provision the subnet.
* Once created, the subnet will be listed under the VCN's subnets.
* Verify the Configuration:
* Go to the subnet details page for IAD-SP-PBT-PUBSNET-01.
* Confirm the CIDR block is 10.0.1.0/24 and that it is a public subnet with Internet Gateway access.
Notes
* Ensure the CIDR block 10.0.1.0/24 does not overlap with existing subnets in the VCN (10.0.0.0/16, including 10.0.10.0/24 from Task 3).
* The Internet Gateway association relies on the route table configuration from Task 3. If it's missing, update the route table as described in Step 6.

See the solution below in Explanation.
Explanation:
Task 2: Create a Compute Instance and Install the Web Server
Step 1: Create the Compute Instance
* Log in to the OCI Console.
* 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).

* 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 <private-key-file> opc@<public-ip-address>
* Replace <private-key-file> with your private key path and <public-ip-address> 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 http://
<public-ip-address> 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
