A cloud engineer needs to enable routing between two Virtual Cloud Networks (VCN) from his tenancy. The VCNs are in the same region but in different compartments. After reviewing the IPv4 CIDR prefixes of the two VCNs, he notices that there are no overlapping CIDR blocks.

Which THREE are valid Oracle Cloud Infrastructure (OCI) options for connecting and routing between the two VCNs? (Choose three.)

A. Create two DRGs in the tenancy. Attach one VCN to one of the DRGs; attach the other VCN to the second DRG. In each one of the DRGs, create a Virtual Circuit Attachment. Select FastConnect Partner as the FastConnect type. Select any vendor from the list and complete the circuit at the partner site. Once the FastConnect IPv4 BGP field is in the UP state in each one of the Virtual Circuits, add a route rule in each one of the VCNs' route table to the other VCN using the DRG as the next hop.

B. Create two DRGs in the tenancy. Attach one VCN to one of the DRGs; attach the other VCN to the second DRG. In each one of the DRGs, create a Remote Peering Connection (RPC). Establish a connection from one RPC to the other. In each one of the VCNs' route table, add a route rule to the other VCN using the DRG as the next hop.

C. Create a DRG in the tenancy; add one of the VCN as a VCN attachment. In the other VCN, create a Local Peering Gateway (LPG). Peer the DRG to the LPG. In the VCN attached to the DRG, add a route rule in the route table that points to the DRG as the next hop. In the other VCN, add a route rule in the route table that points to the LPG as the next hop.

D. Add an LPG to each one of the VCNs. In one of the LPG, establish a Peering Connection to the other LPG. In each one of the VCN route table, add a route rule to the other VCN using the LPG as the next hop.

E. Create a DRG in the tenancy; add one of the VCNs as a VCN attachment. In the other VCN, create a Local Peering Gateway (LPG). Peer the DRG to the LPG. In the VCN attached to the DRG, enable BGP routing for the route to propagate to the VCN. In the other VCN add a route rule in the route table that points to the LPG as the next hop.

F. Create a Dynamic Routing Gateway (DRG) in the tenancy, add the two VCNs as VCN attachments and add routes in each one of the VCN route tables with the DRG as the next hop for the CIDR prefix of the other VCN.

Your customer has gone through a recent reorganization. As part of this change, they are organizing their Oracle Cloud Infrastructure (OCI) compartment structure to align with the company's new organizational structure. (Refer to the exhibit)

They have made the following change:

Compartment A is moved, and its new parent compartment is compartment Dev.

Policy defined in compartment A: Allow group G1 to manage instance-family in compartment A

Policy defined in root compartment: Allow group admins to manage instance-family in compartment Ops: Test: A

A. Define the following policy in compartment Dev: Allow group G1 to manage instance-family in compartment A

B. Define the following policies in compartment Dev: Allow group G1 to manage instance-family in compartment A Allow group admins to manage instance-family in compartment Ops: Dev: A

C. Define the following policy in compartment: Dev: Allow group admins to manage instance-family in compartment Ops: Dev: A

D. Mo change in any policy statement is required as all the policies associated with a compartment being moved is automatically updated

An online registration system Is currently hosted on one large Oracle Cloud Infrastructure (OCT) Bare metal compute Instance with attached block volume to store of the users' data. The registration system accepts the Information from the user, Including documents and photos then performs automated verification and processing to check it the user is eligible for registration.

The registration system becomes unavailable at tunes when there is a surge of users using the system the existing architecture needs improvement as it takes a long time for the system to complete the processing and the attached block volumes are not large enough to use data being uploaded by the users.

Which Is the most effective option to achieve a highly scalable solution?

A. Attach more Block volumes as the data volume increase, use Oracle Notification Service (ONS) to distribute tasks to a pool of compute instances working In parallel, and Auto Scaling to dynamically size the pool of Instances depending on the number of notifications received from the Notification Service. Use Resource Manager stacks to replicate your architecture to another region.

B. Change your architecture to use an OCI Object Storage standard tier bucket, replace the single bare metal instance with a Oracle Streaming Service (OSS) to ingest the Incoming requests and distribute the tasks to a group of compute Instances with Auto Scaling

C. Upgrade your architecture to use a pool of Bare metal servers and configure them to use their local SSDs for faster data access Set up Oracle Streaming Service (OSS) to distribute the tasks to the pool of Bare metal Instances with Auto Scaling to dynamically increase or decrease the pool of compute instances depending on the length of the Streaming queue.

D. Upgrade your architecture to use more Block volumes as the data volume Increases. Replace the single bare metal instance with a group of compute instances with Auto Scaling to dynamically increase or decrease the compute instance pools depending on the traffic.

A cloud consultant is working on a implementation project on Oracle Cloud Infrastructure (OCI).

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.

A. Reduce the TTL of the DNS records after the switch.

B. DNS changes propagate fast enough that it is not necessary to take any action.

C. Increase the TTL of the DNS records before the switch.

D. Increase the TTL of the DNS records after the switch.

An eCommerce company is running on Oracle Cloud Infrastructure (OCI) and many compute instances remain unused for the most part of the year except during Black Friday and Christmas. You suggest them to use OCI's

Autoscaling feature and present them a slide to showcase the features of Autoscaling.

Which option below is inaccurate in your presentation to the customer?

A. A cooldown period between Autoscaling events lets the system stabilize at the updated level.

B. When an instance pool scales in, instances are terminated in this order: the number of instances is balanced across Availability Domains, and then balanced across Fault Domains. Finally, within a Fault Domain, the newest instance is terminated first.

C. Autoscaling relies on performance metrics such as CPU utilization that are collected by OCI Monitoring service to trigger an Autoscaling event.

D. Autoscaling requires an instance pool as a pre-requisite so that it can automatically adjust the number of compute instances in an instance pool.
