Question #31

An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two

A. The maximum CPU cores that will be automatically allocated for this database is 16 CPUs

B. Enabling auto scaling does not change the concurrency and parallelism settings

C. The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling

D. Auto scaling also scales IO throughput linearly along with CPU

Question #32

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. You need to set up a Service Gateway to send metrics to the OCI Monitoring service.

B. Autoscaling only works with single availability domains.

C. You need to assign a reserved public IP address to the compute instances.

D. Autoscaling only works for instances with public IP addresses.

Question #33

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 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.

B. Configure your Load Balance, with weighted round robin policy to distribute traffic to the compute instances, with more weight assigned to bare metal 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 Autoscaling instance pool with LoadBalancer to add up to 3 more BM.Standard2.52 Instances when triggered. Shut off VM.Standard2.8 instances.

Question #34

Your customer has gone through a recent departmental re structure. As part of this change, they are organizing their Oracle Cloud Infrastructure (OCI) compartment structure to align with the company's new organizational structure.
They have made the following change:
Compartment x Is moved, and its parent compartment is now compartment c.

Policy defined in compartment A: Allow group networkadmins to manage subnets in compartment X Policy defined in root compartment: Allow group admins to read subnets in compartment Finance:A:X After you move the compartment, which two IAM policies would be required to ensure both groups retain the same permissions to compartment X that they had before? (Choose two.)

A. Define a policy in compartment HR as follows: Allow group networkadmins to manage subnets in compartment C:X.

B. Define a policy in the root compartment as follows: Allow group admins to manage subnets in compartment Finance:A:X

C. Define a policy in compartment C as follows: Allow group networkadmins to read subnets in compartment X

D. Define a policy in the root compartment as follows: Allow group admins to read subnets in compartment HR:C:X

Which of the following is a NOT a true statement?

A. You can create additional custom images of an instance while the instance is engaged in the image creation process.

B. Before you create a custom image of an instance, you must disconnect all iSCSI attachments and remove all iscsid node configurations from the instance.

C. Custom images do not include the data from any attached block volumes.

D. Editing custom Windows images is not supported due to hardware differences between shapes.

Question #38

You are a solutions architect for a global health care company which has numerous data centers around the globe. Due to the ever growing data that your company is storing, you were Instructed to set up a durable, cost effective solution to archive you data from your existing on-premises tape based backup Infrastructure to Oracle Cloud Infrastructure (OCI).
What is the most-effective mechanism to Implement this requirement?

A. Setup an on premises OCI Storage Gateway which will back up your data to OCI Object Storage Archive tier.

B. Setup an on premises OCI Storage Gateway which will back up your data to OCI object Storage Standard tier. Use Object Storage life cycle policy management to move any data older than 30 days from Standard to Archive tier.

C. Setup an on-promises OCI Storage Gateway which will back up your data to OCI Object Storage Standard

D. Setup fastConnect to connect your on premises network to your OCI VCN and use rsync tool to copy your data to OCI Object Storage Archive tier.

E. Use the File Storage Service in OCI and copy the data from your existing tape based backup to the shared file system
