Question 1

A company is securing its compute instances (VMs and Bare Metal Machines) in Oracle Cloud infrastructure (OCI) using a network firewall. As shown in the diagram, traffic flows from the internet Gateway (IGW) to the firewall in the Public DMZ Subnet, and then to the compute instances in the Public Subnet.

When configuring security lists and network security groups (NSGs) in this setup, what should they consider?

A.Security list and NSG rules associated with the firewall subnet and VNICs are evaluated after the firewall.
B.If the policy used with the firewall has no rules specified, the firewall allows all traffic.
C.Ensure that any security list or NSG rules allow the traffic to enter the firewall for appropriate evaluation.
D.Add stateful rules to the security list attached to the firewall subnet or include the firewall in an NSG containing stateful rules for better performance.

Question 2

According to the Oracle Cloud Infrastructure (OCI) Shared Responsibility Model, which statement accurately reflects OCI's responsibility for security?

A.OCI has no security responsibilities; customers need to secure their resources.
B.OCI is responsible for securing the underlying infrastructure but not customer data.
C.OCI provides security only for free-tier services; customers secure everything else.
D.Customers are responsible for securing both infrastructure and data.

Question 3

You are a security architect at your organization and have noticed an increase in cyberattacks on your applications, including Cross-Site Scripting (XSS) and SQL Injection. To mitigate these threats, you decide to use OCI Web Application Firewall (WAF).
Which type of OCI WAF rule should you configure to protect against these attacks?

A.Access control rule
B.Rate Limiting rule
C.Protection rule
D.Encryption rule

Question 4

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.

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 5: Provision a Compute Instance
Provision a compute instance in the IAD-SP-PBT-PUBSNET-01 public subnet, where:
Name IAD-SP-PBT-1-VM-01
image: Oracle Linux 8
Shape VM: Standard, A1, Flex
Enter the OCID of the created compute instance in the text box below.

Correct Answer:

See the solution below in Explanation.
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).
* Note the Instance OCID:
* 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.

Question 5

Challenge 1 - Task 1
Integrate TLS Certificate Issued by the OCI Certificates Service with Load Balancer You are a cloud engineer at a tech company that is migrating its services to Oracle Cloud Infrastructure (OCI). You are required to set up secure communication for your web application using OCI's Certificate service. You need to create a Certificate Authority (CA), issue a TLS/SSL server certificate, and configure a load balancer to use this certificate to ensure encrypted traffic between clients and the backend servers.
