Many development engineers are deploying new instances as part of their projects in Oracle Cloud Infrastructure tenancy, but majority of these instances have not been tagged. You as an administrator of this tenancy want to enforce tagging to identify owners who are launching these instances.
Which option below should be used to implement this requirement?

• A.Create a default tag for each compartment which ensure appropriate tags are allowed at resource creation.
• B.Create an IAM policy to automatically tag a resource with the usemame.
• C.Create tag variables for each compartment to automatically tag a resource with user name.
• D.Create a predefined tag with tag variables to automatically tag a resource with usemame.

You are running a legacy application in a compute instance on Oracle Cloud Infrastructure (OCI). To provide enough space for it to store internal data, a block volume is attached to the instance in paravirtualized mode.
Your application is not resilient to crash-consistent backup.
What should you do to backup the block volume in a secure and cost effective way? (Choose the best answer.)

• A.Save your application data, detach the block volume and create a backup.
• B.Save your application data, detach the block volume and create a clone.
• C.Create a backup, detach the block volume and save your application data.
• D.Create a volume group, add the boot volume and then run the volume group backup.

To serve web traffic for a popular product, your cloud engineer has provisioned four BM.Standard2.52 instances, event spread across two availability domains in the us-asburn-1 region: LoadBalancer is used to deliver the traffic across instances.
After several months, the product grows even more popular and you need additional compute capacity. As a result, an engineer provisioned two additional VM.Standard2.8 instances.
You register the two VM. Standard2. 8 Instances with your load Balancer Backend sot and quickly find that the VM Standard2.8 Instances running at 100% of CPU utilization but the BM.Standard2 .52 instances have significant CPU capacity that's unused.
Which option is the most cost effective and uses instances capacity most effectively?

• A.Configure your Load Balance, with weighted round robin policy to distribute traffic to the compute instances, with more weight assigned to bare metal instances.
• B.Configure Autoscaling instance pool with LoadBalancer to add up to 3 more BM.Standard2.52 Instances when triggered. Shut off VM.Standard2.8 instances.
• C.Route traffic to BM.Standard2.52 and VM Standard2.8 instances directly using DNS and Health Checks. Shut off the load Balances.
• D.Configure LoadBalancer with two VM Standard2.8 instances and use Autoscalling Instant pool to add up to two additional VM instances. Shut off BM.Standard2.52 instances.

A small business specializing in video processing wants to leverage cloud storage in order to lower its costs. They are looking to backup all video data generated, from an existing on-premises file server to Oracle Cloud Infrastructure (OCI). The requirement is to setup continuous data sync as changes are made to on- premises file server. What is the most cost effective solution for this scenario?

• A.Set up file storage service on OCI and mount the file system to an instance running on-premises. Move all the data to this on-premises instance and then sync the videos to the shared file system.
• B.Setup an on-premises OCI Storage Gateway Cloud Sync to back up videos to OCI Object Storage Archive tier.
• C.Set up a VPN connect connection and back up all videos to Object storage standard bucket. Create a lifecycle policy to move files older than 30 days to Archive Storage.
• D.Set up a Fastconnect virtual Circuit and nightly back up all videos to OCI Archive Storage.
