Given this compartment structure:

You are managing a compute instance that currently resides in the Compute compartment. The Virtual Cloud Network (VCN) into which the compute instance was originally deployed, also resides in this compartment. To support a project-related task, you need to move just the compute instance to the SysTest-Team compartment. You log into your Oracle Cloud Infrastructure (OCI) account and use the Move Resource option to place the compute instance in the new compartment.

What will be the result of your attempt to move the compute instance to the new compartment? (Choose the best answer.)

A. The move will be successful. The compute instance's public and private IP addresses will stay the same. The compute instance will remain associated with the VCN from the source compartment.

B. The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the compute instance can be moved.

C. After moving the compute instance, you must move the compute instance VNIC as a separate action. The public and private IP addresses of the instance will remain unchanged and it will still be associated with the VCN from the source compartment.

D. The move will be successful. However, the compute instance's public and private IP addresses will change, and it will be associated to the first VCN that was created in the new, target compartment.

A retail company has recently adopted a hybrid architecture. They have the following requirements for their end-to-end Connectivity model between their on-premises data center and Oracle Cloud Infrastructure (OC1) region

Highly available connection with service level redundancy

*

Dedicated network bandwidth with low latency

Which connectivity setup is the most cost effective solution for this scenario?

A. Setup IPsec VPN as your primary connection, and a FastConnect virtual circuit as a backup connection. Use separate edge devices in your on-premises data canter for each connection from your edge devices, advertise more specific routes IPSec VPN, and specific routes through the backup FastConnect virtual circuit.

B. Setup FastConnect virtual circuit as your primary connection, and a second FastConnect virtual circuit as a backup connection. Use separate edge devices in your FastConnect physical connectivity is redundant Use a single edge device in your on premises data center for each connection From yc device, advertise more specific routes via primary FastConnect virtual circuit, and less specific routes through t backup FastConnect circuit.

C. Setup FastConnect virtual circuit as your primary connection, and an IPSec VPN as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes through FastConnect virtual circuit, and more specific routes through the backup IPSec VPN path.

D. Setup IPSec VPN as your primary connection, and a second IPSec VPN as a backup connection. Use separate edge devices in your on p data center for each connection. From your edge devices, advertise more specific routes via primary IPSec VPN. and less specific rod the backup IPSec VPN.

Which of the following is NOT a good use case for the Oracle Cloud Infrastructure (OCI) Streaming service?

A. Meeting compliance requirements for data to remain unchanged over a long time, so that it can be retrieved for audit purposes.

B. Messaging with a pull-based communication model and the ability to feed multiple consumers with the same data independently.

C. Ingesting metric and log data to help make critical operational data more quickly available for indexing, analysis, and visualization.

D. Providing a unified entry point for cloud components to report their life cycle events for audit, accounting, and related activities.

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.

You have decided to migrate your application to Oracle Cloud Infrastructure and use Oracle Functions to deploy your microservices.

Which monitoring metrics are available to help you calculate your total cost for using Oracle Functions per month? (Choose Two)

A. Amount of RAM used by your functions.

B. Length of time a function runs.

C. Number of times a function is invoked.

D. Amount of storage used by your functions.

E. Network bandwidth used by your functions.

Which three options are available to migrate an Oracle database 12.x from an on-premises environment to Oracle Cloud Infrastructure (OCI)?

A. Leverage OCI Storage Gateway asynchronous database migration option.

B. Use Oracle Data Pump Export/Import to migrate the database.

C. Configure RMAN cross-platform transportable tablespace backup sets.

D. Setup OCI schema and data transfer tool with Bare Metal DB Systems as the target.

E. Create a backup of your on-premises database In OCI DB Systems.

A customer is in a process of shifting their web based Sales application from their own data center located in US West to OCI India West (Mumbai) region. They want to do it in a controlled manner and initially only 1% of the traffic will be steered to the servers in OCI. After verification of everything is working as expected, the company is gradually planning to increase the ratio until they are comfortable with fully migrating all traffic to OCI.

Which of the following solution can be used in this situation?

A. OCI DNS and Traffic Management with Geolocation Steering policy

B. OCI DNS and Traffic Management with Failover Steering policy

C. OCI DNS and Traffic Management with Load Balancer Steering policy

D. OCI DNS and OCI Load Balancer Service

An Oracle Cloud Infrastructure (OCI) Public Load Balancer's SSL certificate is expiring soon. You noticed the Load Balancer is configured with SSL Termination only. When the certificate expires, data traffic can be interrupted and security compromised.

What steps do you need to take to prevent this situation?

A. Add the new SSL certificate to the Load Balancer, update backend servers to work with a new certificate and edit listeners so they can use the new certificate bundle.

B. Add the new SSL certificate to the Load Balancer, update listeners and backend sets so they can use the new certificate bundle.

C. Add the new SSL certificate to the Load Balancer and implement end to end SSL so it can encrypt the traffic from clients all the way to the backend servers.
