Question # 8

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

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.

Task 4: Create a Certificate Authority (CA)

Create a certificate authority, where:

CA name: PBT-CERT-CA-01-

For example, if your username is 99008677-lab.user01, then the certificate authority name should be PBT-CERT-CA-01990086771abuser01

Question # 11

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?

It automatically encrypts data at rest on the bare metal instance.

It ensures all non-volatile memory on the terminated instance is securely wiped before reuse.

It guarantees complete isolation between customer workloads on different instances.

It eliminates the need for hypervisors, reducing the potential attack surface.

Question # 12

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?

VM-02 can SSH into VM-01, but VM-01 cannot SSH into VM-02.

VM-01 can SSH into VM-02, but VM-02 cannot SSH into VM-01.

Both VM-01 and VM-02 can SSH into each other.

Neither VM-01 nor VM-02 can SSH into each other."

Question # 13

"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?

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."

Question # 14

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?

Incorrect subnet configuration

Misconfigured security rule

Incorrect DNS configuration

Overloaded back-end servers

Misconfigured health check

Question # 15

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 --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?

The instance is using the wrong OCI CLI authentication method.

The bucket name is already in use, causing a conflict.

The policy is written at the root compartment instead of the production compartment.

The instance is not part of any Dynamic Group or the matching rule is incorrect.
