• Question 161:

  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.

  Correct Answer: ACD

• Question 162:

  A global media organization is working on a project which lets users upload their videos to the site. After upload is complete, the video should be automatically processed by an Al algorithm. The algorithm will try to recognize certain actions in the videos so that it can be used to show related advertisements in future. The development team wants to focus on writing Al code and not worry about underlying infrastructure for high availability, scalability, security and monitoring.

  C. OCI Events, Oracle Container Engine for Kubernetes and OCI Digital Assistant.

  D. OCI Resource Manager, OCI Functions and OCI Events service.

  Correct Answer: A

• Question 163:

  A company has an application that processes confidential data. The data is currently stored in an on-premises data center. A solution architect needs to move this data to Oracle Cloud Infrastructure (OCI) Object Storage and ensure data is encrypted in-transit to OCI.

  Which two steps should the solution architect perform to set up the most cost-effective connection between on-premises data center and OCI?

  A. Set up private end point for accessing Object Storage.

  B. Attach an Internet Gateway to Virtual Cloud network(VCN).

  C. Configure a service gateway accessing Object Storage.

  D. Set up an IPsec tunnel between the customer equipment and software VPN on an oci instance

  E. Configure a private peering connection on the Oracle FastConnect

  F. Set up VPN Connect between the customer equipment and the Dynamic Routing Gateway.

  Correct Answer: CF

• Question 164:

  You are working as a solutions architect for an online retail store In Frankfurt which uses multiple compute instance VMs spread among three availability domains In the eu- frankfurt-1 region.

  You noticed the website Is having very high traffic, so you enabled autoscaling to sun tee me no f your application but, you observed that one of the availability domains is not receiving any traffic.

  What could be wrong In this situation?

  A. Autoscaling only works with single availability domains.

  B. You have to manually acid all three availability domains to your load balancer configuration.

  C. Autoscaling can be enabled for multiple availability domains only in uk-london t region.

  D. Autoscaling is using an Instance Pool configured to create instances in two availability Domains.

  E. You forgot to attach a load balancer to your instance pool configuration.

  Correct Answer: D

  Autoscaling lets you automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand. you can associate a load balancer with an instance pool. If you do this, when you add an instance to the instance pool, the instance is automatically added to the load balancer's backend set . After the instance reaches a healthy state (the instance is listening on the configured port number), incoming traffic is automatically routed to the new instance. Instance pools let you provision and create multiple Compute instances based off the same configuration, within the same region. By default, the instances in a pool are distributed across all fault Domains in a best-effort manner based on capacity. If capacity isn't available in one fault domain, the instances are placed in other fault domains to allow the instance pool to launch successfully. In a high availability scenario, you can require that the instances in a pool are evenly distributed across each of the fault domains that you specify. When sufficient capacity isn't available in one of the fault domains, the instance pool will not launch or scale successfully, and a work request for the instance pool will return an "out of capacity" error. To fix the capacity error, either wait for capacity to become available, or use the UpdateInstancePool operation to update the placement configuration (the availability domain and fault domain) for the instance pool. during create the instance pool you can select the location where you want to place the instances" In the Availability Domain list, select the availability domain to launch the instances in. If you want the instances in the pool to be placed evenly in one or more fault domains, select the Distribute instances evenly across selected fault domains check box. Then, select the fault domains to place the instances in.

• Question 165:

  A company has an urgent requirement to migrate 100 TB of data to Oracle Cloud Infrastructure (OCI) in two weeks. They have a 100 Mbps Internet line but the connection is intermittent due to problems with their internet provider. In this scenario, what is the most time-efficient mechanism to migrate data to OCI?

  A. Set up an IPSec VPN tunnel between your data center and OCI. Upload all data to OCI using OCI Storage Gateway.

  B. Set up an OCI Storage Gateway to connect your data center to your Virtual Cloud Network and upload data.

  C. Upload data using OCI Object Storage multipart upload capability.

  D. Set up hybrid network by launching a 1 Gbps FastConnect virtual circuit between your data center and OCI. Use OCI Object Storage multipart upload capability to automate the migration of your data to OCI.

  E. Use OCI File Storage Service to copy data from your data center to OCI.

  Correct Answer: D
