 Creating and managing records, creating and managing zones, and viewing all zones are three capabilities that are available with the OCI DNS service. Records are data elements that map domain names to IP addresses or other information. Zones are collections of records that correspond to a domain name or a subdomain name. The OCI DNS service allows users to create and manage records and zones for their domains or subdomains, as well as view all zones in their tenancy. The other options are not capabilities of the OCI DNS service, but of other OCI services such as WAF, IAM, and Networking. References: [DNS Service], [Records], [Zones]

Audit is the OCI service that would help identify the details of all users who were active in the last six hours along with any REST API calls that were executed. Audit is a service that records all API calls and other actions taken by or on behalf of users in OCI. It can be used to track user activity, monitor compliance, and troubleshoot issues. The other options are not suitable for this task. References: [Audit]

Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges. The explanation is that a VCN CIDR prefix is the range of IPv4 addresses that can be used within the VCN and its subnets. The VCN CIDR prefix should not overlap with other VCNs in your tenancy or with your organization’s private IP network ranges, as this can cause routing conflicts and connectivity issues. You should choose a VCN CIDR prefix that is large enough to accommodate your current and future needs, but not too large to waste IP addresses. You can use any of the private IPv4 address ranges specified in RFC 1918 for your VCN CIDR prefix.

According to the Oracle Cloud Guard documentation1, Cloud Guard is a cloud native service that helps customers monitor, identify, achieve, and maintain a strong security posture on Oracle Cloud. Use the service to examine your Oracle Cloud Infrastructure resources for security weakness related to configuration, and your Oracle Cloud Infrastructure operators and users for risky activities. Upon detection, Cloud Guard can suggest, assist, or take corrective actions, based on your configuration.

Therefore, option A and option E are correct ways that Cloud Guard helps improve the overall security posture for your tenancy. Option B is incorrect because Cloud Guard does not allow you to centrally manage encryption keys. That is the function of the Vault service2. Option C is incorrect because Cloud Guard does not prevent you from creating misconfigurations on your resources in OCI. It only detects and reports them, and optionally takes corrective actions. Option D is incorrect because Cloud Guard does not mask sensitive data and monitor security controls on your Oracle databases. That is the function of the Data Safe service3.

Exadata Virtual Machine is not a valid option for an OCI compute shape. Exadata Virtual Machine is a deployment option for Exadata Cloud Service or Exadata Cloud@Customer, which are services that provide dedicated Exadata infrastructure for running Oracle databases in OCI. Exadata Virtual Machine allows you to create multiple virtual machines on each Exadata compute node and isolate them from each other using Oracle VM technology. The valid options for OCI compute shapes are:

• Bare Metal: A bare metal instance is a physical server that gives you direct access to the underlying hardware and full isolation from other tenants.
• Dedicated Virtual Machine Host: A dedicated virtual machine host is a physical server that hosts only your virtual machine instances and no other tenant’s instances.
• Virtual Machine: A virtual machine instance is a virtual server that runs on a shared physical server with other tenants’ instances.
• Burstable: A burstable instance is a virtual machine instance that has a baseline utilization of either 12% or 50% of each CPU core and can burst above the baseline when needed.
