You are working as a solution architect for a customer in Frankfurt, which uses multiple compute instance VMs spread among three Availability Domains in the Oracle Cloud Infrastructure (OCI) eu-frankfurt-1 region. The compute instances do not have public IP addresses and are running in private subnets inside a Virtual Cloud Network (VCN). You have set up OCI Autoscaling feature for the compute instances, but find out that instances cannot be auto scaled. You have enabled monitoring on the instances.
What could be wrong in this situation?

• A. Autoscaling only works with single availability domains.
• B. You need to set up a Service Gateway to send metrics to the OCI Monitoring service.
• C. You need to assign a reserved public IP address to the compute instances.
• D. Autoscaling only works for instances with public IP addresses.

A cloud consultant is working on implementation project on OCI. As part of the compliance requirements, the objects placed in object storage should be automatically archived first and then deleted. He is testing a Lifecycle Policy on Object Storage and created a policy as below:
[ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes": "doc"] },
"timeAmount": 5, "timeunit": "DAYS", "isEnabled": true },
{ "name": "Delete_doc", "action": "DELETE", "objectNameFilter": "inclusionPrefixes": [ "doc"]
1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }
What will happen after this policy is applied?

• A. All the objects having file extension ".doc" will be archived for 5 days and will be deleted 10 days after object creation
• B. All objects with names starting with "doc" will be deleted after 5 days of object creation
• C. All the objects having file extension ".doc" will be archived 5 days after object creation
• D. All the objects with names starting with "doc" will be archived 5 days after object creation and will be deleted 5 days after archival

You are tasked with backing up your data using Oracle Cloud Infrastructure Block Volume service.
When you are finalizing your block volume backup schedule, which of the following two are valid considerations for your backup plan? (Choose Two)

• A. Frequency: How often you want to back up your data.
• B. Location: Determine the Object Store Bucket where the backups will be stored.
• C. Number of stored backups: How many backups you need to keep available and the deletion schedule for those you no longer need.
• D. Governance: Tagging of backups so you can capture backup related API calls through the Audit service.
• E. Encryption: Whether to use your own key to encrypt your volume backups.

You are advising the database administrator responsible for managing non-production environment for Oracle Autonomous Database running on Oracle Cloud Infrastructure. You need to help the database administrator ensure that the non-production environments have a copy of the current data from the production environment in a manner that is most time-efficient.
Which method should you recommend? (Choose the best answer.)

• A. Create a full clone of the production Autonomous Database and create the non-production database from it.
• B. Create a metadata clone of the production Autonomous Database and create the non-production database from it.
• C. Take a full database backup of the production Autonomous database and create the non-production database from it.
• D. Take a Data Pump export of the production Autonomous database and import into the non-production database.

You are working with a customer who needs to attach an Oracle Cloud Infrastructure (OCI) block volume to a VM instance with read/write access type. The customer wants to know if the number of IOPS and throughput performance differs between the following two choices:
* Option A: attach a single 1 TB block volume to the VM instance
* Option B: attach two separate 500 GB block volumes In a RAID 0 array configuration to the VM instance You can assume that the customer is using iSCSI attachment type to attach the volumes to the instance. In addition, you can assume 1 MB block size for throughput and 4 KB block size for IOPS consideration.
How should you respond to the customer?

• A. Option A provides better IOPS, but lower throughput performance.
• B. Option B provides higher level of throughput, but lower level of IOPS performance.
• C. Option B provides better IOPS and throughput performance.
• D. Both options provide the same number of IOPS and throughput performance.
