NO.16 Task 4: Create a Certificate Authority (CA)
Create a certificate authority, where:
CA name: PBT-CERT-CA-01-<username>
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)

NO.17 A company has deployed OCI Zero Trust Packet Routing (ZPR) to secure its network. They have two compute instances, VM1-01 and VM-02, in a public subnet. VM-01 is tagged with the security attribute app:
vm01, and VM-02 is tagged with app:vm02. The VCN is labeled with network:vcn01, The ZPR policy states:


“What is the expected outcome of this policy?

NO.18 Which Oracle Data Safe feature enables the Internal test, development, and analytics teams to operate effectively while minimizing their exposure to sensitive data?

NO.19 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.

NO.20 You are the first responder of a security incident for ABC Org. You have identified several IP addresses and URLs in the logs that you suspect may be related to the incident. However, you need more information to confidently determine whether they are indeed malicious or not.
Which OCI service can you use to obtain a more refined information and confidence score for these identified indicators?

NO.21 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?

NO.22 “A programmer is developing a Node.js application which will run on a Linux server on their on-premises data center. This application will access various Oracle Cloud Infrastructure (OCI) services using OCI SDKs.
What is the secure way to access OCI services with OCI Identity and Access Management (IAM)?

NO.23 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?

NO.24 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?

NO.25 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
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.

NO.26 An OCI administrator notices that a compute instance running in the production compartment is unable to create Object Storage buckets using the OCI CLI command:
oci os bucket create –name mybucket –compartment-id <compartment_OCID> –auth instance_principal The error message returned states:
“NotAuthorizedOrNotFound: You are not authorized to perform this action.” The administrator verifies that the instance has Internet access and can reach OCI endpoints.
What then could be causing the issue?

NO.27 A company has implemented OCI IAM policies with multiple levels of compartments. A policy attached to a parent compartment grants “manage virtual-network-family” permissions. A policy attached to a child compartment grants “use virtual-network-family” permissions.

According to OCI IAM policy inheritance, how does the OCI IAM policy engine resolve the permissions for a user attempting to perform an operation that requires ‘manage’ permissions in the child compartment?

NO.28 You have created a compartment TEST in your subscribed tenancy. Then, you created two groups, test1 and test2, and want the users in these groups to be able to manage all the resources in the TEST compartment.
Which policy would you use to achieve this?

NO.29 “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?

NO.30 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?
