The data sitting on this instance needs to be copied to OCI Object storage bucket available in the same region without traversing over the internet. To enable the connectivity between the instance and Object Storage, you created a service gateway with service CIDR of all Object Storage in us-phoenix-1 enabled. You also modified the security rules to allow the desired traffic. However, when you tried sending the data to the Object Storage bucket, you notice that the data is going over the internet and not via the service gateway. What could be the possible reason for this behavior? A. Identity and Access Management (IAM) policies restrict the access to the object storage bucket. B. The service gateway created in the VCN resides in a different availability domain. C. The security list associated with the subnet has an egress rule that allows all traffic to be forwarded to a destination CIDR 0.0.0.0/0. D. The route table associated with the subnet has no route rule where the destination is object storage service.
Which two choices are true for Oracle Autonomous Database with Shared Exadata Infrastructure? (Choose two.) A. Autonomous database does not support per-second billing. B. Billing for compute usage stops when autonomous database is stopped. C. Billing for storage usage continues when autonomous database is stopped. D. Billing stops for both CPU and storage usage when autonomous database is stopped. E. Billing does not stop when autonomous database is terminated.
You are responsible for creating and maintaining an enterprise application that consists of multiple storage volumes across multiple compute instances in Oracle Cloud Infrastructure (OCI). The storage volumes include boot volumes and block volumes for your data storage. You need to create backups of these storage volumes in the most time- efficient manner. How can you meet this requirement? A. Create clones of all boot volumes and block volumes one at a time. B. Create on-demand full backups of boot volumes, and copy data in block volumes to Object Storage using OCI CLI. C. Create on-demand full backups of block volumes, and create custom images from the boot volumes. D. Group together multiple storage volumes in a volume group and create volume group backups.
As an Oracle Cloud Infrastructure tenancy administrator, you created predefined lists of values and associated them with tag key definitions. One of the users in your tenancy complains that she cannot see these predefined values. What is causing this issue? A. The user is trying to use free-form tags. B. Some of the predefined values are null. C. The user is not part of an Identity and Access Management group that gives access to tagging. D. The user has breached either the quota or service limit for using tags.
You have compartments C and D under the root compartment in your Oracle Cloud Infrastructure (OCI) tenancy; compartment C contains a sub-compartment also named D. You are trying to move this sub-compartment D to the parent compartment D like shown in the picture, but the move fails. A. You need to move all the compartments in the hierarchy to the new parent compartment. B. You cannot move a subcompartment to another parent compartment. C. Both parent and child compartments cannot have the same name. D. Sub-compartment D needs to be empty before it can be moved.
You are working for a financial institution that is currently running two web applications in Oracle Cloud Infrastructure (OCI). All resources were created in the root compartment. Your manager asked you to deploy new resources to support a proof-of-concept (PoC) for Oracle FlexCube. You must ensure that the FlexCube resources are secured and cannot be affected by the team that manages the two web applications. Which two tasks should you complete to ensure the required security of your resources? (Choose two.) A. Create a new compartment for the two web applications and move the existing resources into the compartment. Deploy the FlexCube application into the root compartment. Create a new policy in the root compartment that gives the FlexCube project team the ability to manage all resources in the tenancy. B. Create a new policy in the root compartment for the FlexCube project team. Assign a policy statement that grants the FlexCube project team the ability to manage all resources in the tenancy, where a specific tag key and tag value are present. C. Create a Tag Default within the root compartment with a default value of ${iam.principle.name} so that each new resource created is tagged with the name of the person who created it. Create a new IAM policy that allows users to only modify resources they created. D. Create a new compartment for the two web applications and move the existing resources into this compartment. Modify the existing policy for the team that manages these applications so that the scope of access is defined as this new compartment. E. Create a new compartment for the FlexCube application deployment. Create a policy in this compartment for the project team that gives them the ability to manage all resources within the scope of this compartment.
