As a solution architect, you are showcasing the Oracle Cloud Infrastructure (OCI) Object Storage feature

about Object Versioning to a customer.

Which statement is true in regards to OCI Object Storage Versioning?

A. Object versioning does not provide data protection against accidental or malicious object update, overwrite, or deletion.

B. By default, object versioning is disabled on a bucket.

C. A bucket that is versioning-enabled can have only and always will have a latest version of the object in the bucket.

D. Objects are physically deleted from a bucket when versioning is enabled.

You have created a virtual cloud network (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system so you have provisioned one using the file storage service (FSS). You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that both application servers and the DB System can access the file system. The security team determines that the DB System should have read-only access to the file system. What change would you make to satisfy this requirement?

A. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.

B. Connect via SSH to one of the application servers where the file system has been mounted. Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.

C. Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateless.

D. Create an instance principal for the DB System. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the file storage service.

What is the default backup location for database backup on Database Cloud Service (DBCS)?

A. Object Storage on Oracle Cloud Infrastructure

B. ASM diskgroup

C. block volume

D. locally attached NVMe on Virtual Machine

What does Terraform use to create, manage, and manipulate infrastructure resources?

A. resources

B. provisioner

C. instances

D. provider

You are an administrator with an application running on OCI. The company has a fleet of OCI compute virtual instances behind an OCI Load Balancer. The OCI Load Balancer Backend Set health check API is providing a `Critical' level warning. You have confirmed that your application is running healthy on the backend servers. What is the possible reason for this `Critical' warning?

A. A user does not have correct IAM credentials on the Backend Servers.

B. The Backend Server VCN's Route Table does not include the route for OCI LB.

C. OCI Load Balancer Listener is not configured correctly.

D. The Backend Server VCN's Security List does not include the IP range for the source of the health check requests.

Which two statements about the Oracle File Storage Service (FSS) Security are accurate? (Choose two.)

A. Oracle IAM controls which filesystems are mountable by which instances.

B. Security lists can be used as a virtual firewall to prevent an instance from mounting an FSS mount target within a subnet.

C. Encryption of file storage in FSS is optional.

D. Data in transit to an FSS mount target is encrypted.

E. FSS leverages UNIX user group and permission checking for file access security.

You have an application running on Oracle Cloud Infrastructure. You identified that the read and write operations are slowing your application down enough to impair user access. The application is currently using a VM.Standard 1.2 compute without any block storage attached to it. Which two options allow you to increase disk performance? (Choose two.)

A. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.

B. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.

C. Create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.

D. Terminate the compute instance and create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.

You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region. You were asked to create a disaster recovery (DR) plan that will protect against the loss of critical dat

A. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public Internet. Which is the recommended disaster recovery plan?

B. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DR sites.

C. Create a DR environment in Ashburn. Associate a DRG with the VCN in each region and create a remote peering connection between the two VCNs.

D. Create a DR environment in Ashburn and provision a FastConnect virtual circuit using DRG between the regions.

E. Create a DR environment in Ashburn. Associate a dynamic routing gateway (DRG) with the VCN in each region and configure an IPsec VPN connection between the two regions.

You are an administrator with an application running in Oracle Cloud Infrastructure (OCI). The company has a fleet of OCI compute virtual instances behind an load balancer. The load balancer backend set health check API is providing a 'Critical' level warning. You have confirmed that your application Is running healthy on the backend servers. What Is the possible reason for this 'Critical' warning?

A. The load balancer listener is not configured correctly.

B. The security list associated with the subnet In which the backend server is provisioned does not include the IP range for the source of the health check requests.

C. A user does not have correct Identity and Access Management (IAM) credentials on the backend servers.

D. The route table associated with the subnet in which the backend server is provisioned does not include the route for the OCI load balancer.

Which of the following two tasks can be performed in the Oracle Cloud Infrastructure Console for Autonomous Data Warehouse?

A. Adjust Network Bandwidth

B. Scale up/down Memory

C. Increase Storage allocated for Database

D. Scale up/down CPU
