Question 24

Your organization is migrating a critical three-tier application to OCI. The application requires a highly available and performant database tier. You plan to use Oracle Autonomous Database on Dedicated Exadata Infrastructure. The Autonomous Database subnet must adhere to the organization's security policy, which mandates no direct internet access and private access to other VCN subnets. You need to ensure the proper IP address allocation and routing. Which of the following procedural steps is most effective for achieving this?

Options:

Create a public subnet for the Autonomous Database and configure a Service Gateway with access to all Oracle Services in OCI. Configure NSG rules allowing only traffic from the application's compute instances.

Create a private subnet for the Autonomous Database and configure a Service Gateway with access to only Object Storage and Yum Server Oracle Services in OCI. Configure NSG rules allowing only traffic from the application's compute instances, and configure routing to a Dynamic Routing Gateway (DRG) for access to other VCN subnets.

Create a private subnet for the Autonomous Database and configure a Service Gateway with access to Autonomous Database Oracle Services in OCI. Configure NSG rules allowing only traffic from the application's compute instances, and configure routing to a Dynamic Routing Gateway (DRG) for access to other VCN subnets. Reserve a large CIDR block for future database expansion.

Create a public subnet for the Autonomous Database, assign it a public IP address, and configure a Service Gateway with access to all Oracle Services in OCI. Configure routing to an Internet Gateway. Secure access using Security Lists allowing traffic only from approved IP ranges.

Question 25

You're automating the creation of multiple VCNs across different OCI regions using Cloud Shell scripting. Which authentication method within Cloud Shell is best suited to programmatically authenticate with OCI, ensuring both security and scalability for this automation task?

Options:

Using the default Cloud Shell user and configuring the OCI CLI with API keys in a shell script.

Creating a dedicated IAM user for automation, generating API keys, storing the keys securely in Cloud Shell’s persistent storage, and using them in the scripts.

Leverage Instance Principals in conjunction with a dynamic group that includes your Cloud Shell session.

Using Resource Manager stack with Terraform to provision network resources including cross-region configurations, leveraging OCI Vault to handle the sensitive credentials used in Terraform scripts.

Question 26

A development team has deployed a three-tier application in an OCI VCN. The application consists of a public-facing web tier, an application tier, and a database tier. The team reports that the web tier instances can communicate with the application tier instances, but the application tier instances cannot connect to the database tier instances. All security lists are configured to allow all traffic within the VCN. Which OCI Networking diagnostic tool would BEST help you quickly isolate the root cause of this connectivity issue?

Options:

VCN Flow Logs

Connection Diagnostics

Network Firewall

OCI Bastion
