Allow group A-Developers to create volumes in compartment Project-A is an invalid IAM policy. This is because create is not a valid verb for volumes. The correct verb for creating volumes is attach. The other options are valid IAM policies that use correct verbs and syntax. References: [IAM Policies], [Verbs]

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]

 You can change the block volume size when cloning a volume. The explanation is that cloning a volume is a way of creating an exact copy of an existing volume without creating a backup first. Cloning a volume is faster and cheaper than creating a backup and restoring it to a new volume. When you clone a volume, you can change the block volume size, performance, encryption settings, and tags of the new volume. You do not need to detach a volume before cloning it, as cloning does not affect the source volume or its attachments. You cannot clone a volume to another region, as cloning only works within the same region and availability domain. Creating a clone usually takes less time than creating a backup of a volume, as cloning does not involve transferring data to Object Storage.

Create a replication policy to send data to a different bucket in another OCI region. The explanation is that replication is a feature of Object Storage that allows you to automatically copy objects from one bucket to another bucket, either in the same region or in a different region. Replication can help you improve data availability and durability, as well as meet compliance and disaster recovery requirements. To enable replication, you need to create a replication policy that specifies the source and destination buckets, the replication frequency, and the replication filters. Replication policies are evaluated every five minutes and copy any new or updated objects from the source bucket to the destination bucket.

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.

There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use the key. The explanation is that when you create an Object Storage bucket with encryption using a customer-managed key from Vault, you need to have an IAM policy that allows the Object Storage service to use the key on your behalf. The policy should look like this:

allow service objectstorage- to use key in compartment

where is the region where your bucket resides and is the compartment where your key resides.

 From the version 1 menu on the OCI console, select “Promote to Current”. The explanation is that when you promote a secret version to current, it becomes the latest version of the secret and is used by default when you access the secret. This way, you can rollback to a previous version of the secret without creating a new version.

According to the Oracle Cloud Infrastructure documentation1, autoscaling enables you to automatically adjust the number of compute instances in an instance pool based on performance metrics such as CPU and memory utilization. You select a performance metric to monitor and set thresholds that the performance metric must reach to trigger an autoscaling event. When system usage meets a threshold, autoscaling dynamically resizes the instance pool in near-real time. As load increases, the pool scales out. As load decreases, the pool scales in.

Therefore, option B is the correct answer, as it allows you to monitor the memory usage of your application and scale up the number of instances when it meets or exceeds a predefined threshold. This will prevent poor application performance due to insufficient memory.

Premium is the IAM Identity Domain type that you should create if you want a full-featured IDaaS solution that helps you manage workforce authentication and access to all of your Oracle and non-Oracle applications. Premium Identity Domain provides users with access to Oracle Identity Cloud Service, which is an IDaaS solution that offers identity management, single sign-on, multifactor authentication, identity governance, and integration with third-party applications. The other options are not IAM Identity Domain types that provide a full-featured IDaaS solution. References: [Identity Domains], [Oracle Identity Cloud Service]

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.

 The explanation is that Microsoft Azure is one of the cloud providers that has an interconnect location with OCI in London. This means that you can use OCI FastConnect to establish a private and dedicated connection between OCI and Azure in London, with high bandwidth and predictable performance. This connection can also enable you to leverage OCI Autonomous Data Warehouse ML capabilities from Azure resources, as you can access OCI services across regions using private IP addresses. The interconnect location can be provisioned quickly using the OCI and Azure consoles or APIs.

Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers. The explanation is that QCOW2 is one of the supported formats for importing custom images to OCI. Custom images are images that you can create from your own on-premises or cloud servers and use them to launch instances in OCI. To import a custom image, you need to export your current image in a supported format, copy it to an Object Storage bucket, and then import it as a custom image using the OCI console or API. When you import a custom image, you can choose between native mode or emulated mode. Native mode offers better performance but requires compatible drivers and firmware. Emulated mode offers better compatibility but lower performance.
