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.

The explanation is that shielded instances are VM instances that have additional security features to protect them from low-level threats, such as rootkits and bootkits that can infect the firmware and operating system and are difficult to detect. Shielded instances use verified boot, which ensures that only trusted software components are executed during the boot process. Shielded instances also use virtual trusted platform module (vTPM), which provides a secure storage for encryption keys and certificates. Shielded instances are available for Oracle Linux 8 platform images with VM.Standard2.* shapes.

The explanation is that the Infrequent Access tier is suitable for storing data that is accessed less frequently but requires immediate access when needed. The Infrequent Access tier has lower storage costs than the Standard tier, but higher retrieval costs. The Infrequent Access tier also has a minimum storage duration of 30 days, which means that you will be charged for at least 30 days of storage even if you delete or move the data before that period.

Interval is the field that provides the time window for aggregating metric data points plotted on the metric chart. Interval is a parameter that specifies how often metric data points are collected and aggregated by the Monitoring service. For example, an interval of 5 minutes means that metric data points are aggregated every 5 minutes and displayed on the chart. The other options are not fields that provide the time window for aggregating metric data points, but rather other parameters that define the metric query. References: [Interval]

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.

If you choose not to proactively reboot the instance before the scheduled maintenance due date, the instance is either reboot-migrated or rebuilt in place for you. Reboot-migration is a process where OCI migrates your instance to a new physical host without changing its configuration or public IP address. Rebuild in place is a process where OCI shuts down your instance, performs maintenance on the physical host, and restarts your instance with the same configuration and public IP address. The other options are not correct. References: [Reboot-Migration], [Rebuild in Place]

Auth Tokens is the authentication option that you should use to ensure that your custom application with third-party APIs can communicate with OCI resources. Auth Tokens are tokens that can be used as an alternative to passwords when making API calls to OCI services. Auth Tokens can be generated and revoked by users in the OCI Console or CLI, and can be used with any API client that supports basic authentication. The other options are not suitable for this scenario, as they either require OCI’s signature-based authentication or are not applicable for API calls. References: [Auth Tokens]

Oracle Security Zones is a service that helps you enforce best practices and prevent misconfigurations on your OCI resources by applying predefined policies and controls. Some of the benefits of using Security Zones are:

• Encrypt storage resources with a customer-managed key: Security Zones require that all storage resources, such as block volumes, boot volumes, file systems, and object storage buckets, are encrypted with a customer-managed key from Vault. This ensures that you have full control over the encryption and decryption of your data at rest.
• Deny public access to OCI resources, such as databases and object storage buckets: Security Zones prevent you from creating or updating OCI resources that have public access enabled, such as databases and object storage buckets that are accessible from the internet. This reduces the risk of unauthorized access or data leakage.

It encrypts and isolates in-use data and the applications processing that data, thereby preventing unauthorized access or modification is an accurate description of the key features and benefits of OCI Confidential Computing. Confidential Computing is a feature that leverages hardware-based Trusted Execution Environments (TEEs) to protect data and applications from unauthorized access or modification while they are in use by the CPU or memory. This adds an extra layer of security to cloud computing, as it protects data not only at rest and in transit, but also in use. The other options are not accurate descriptions of the key features and benefits of OCI Confidential Computing. References: [Confidential Computing]

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.

Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C. The explanation is that when you attach a policy to the tenancy, you need to specify the full path of the compartment where you want to grant permissions. In this case, the compartment C is a sub-compartment of compartment B, which is a sub-compartment of compartment A, which is a sub-compartment of the root compartment (tenancy). Therefore, the full path of compartment C is A:B:C. The virtual-network-family resource type includes all the resources related to VCN, such as subnets, route tables, security lists, gateways, etc.

Network Visualizer is the tool that provides a diagram of the implemented topology of all VCNs in a selected region and tenancy. Network Visualizer is a feature of the OCI Networking service that allows users to view and manage their network resources in a graphical interface. It can help users understand their network topology, troubleshoot issues, and optimize performance. The other options are not tools that provide a diagram of the VCN topology, but rather other features or services of OCI Networking. References: [Network Visualizer]

SSH traffic is not allowed in the security list nor on the NSG from the Internet is the correct answer. This is because the security list only allows ingress traffic from 10.0.0.24 on port 22, and the NSG only allows ingress traffic from 10.0.0.0/16 on port 22. Neither of them allows ingress traffic from 0.0.0.0/0 (the Internet) on port 22, which is required for SSH access. The other options are not correct, as they do not explain why SSH access is not possible. References: [Security Lists], [Network Security Groups]

Object Versioning is disabled on a bucket by default is a true statement regarding OCI Object Storage Versioning. Object Versioning is a feature that allows users to preserve, retrieve, and restore every version of every object stored in a bucket. Object Versioning is disabled on a bucket by default, but can be enabled or suspended by the user at any time. The other statements are false regarding OCI Object Storage Versioning.
