Which of the below options for private access to services within Oracle Cloud Infrastructure (OCI) is NOT valid?

You have been asked to review some network proposals by a major client. The client's IT director needs to
provision two Virtual Cloud Network (VCN) for a major application. Both applications use a large number of
virtual machine instances, and so will ideally occupy VCNs with as many address spaces as possible.
Additionally, in the future, VCN peering will be required to allow communication between the VCNs.
Which of the following are valid IP ranges to consider for the VCNs?
A. 10.0.0.0/24 and 10.0.1.0/24
B. 10.0.1.0/24 and 10.0.1.0/27
C. 10.0.0.0/16 and 10.0.64.0/24
D. 10.0.0.0/8 and 11.0.0.0/8
Your Oracle database is deployed on-premises and has produced 100 TB database backup locally. You have a disaster recovery plan that requires you to create redundant database backups in Oracle Cloud Infrastructure (OCI).
Once the initial backup is completed, the backup must be available for retrieval in less than 30 minutes to support the Recovery Time Objective (RTO) of your solution. Which is the most cost effective option to meet these requirements?
A. Setup an IPsec VPNConnect between on-premises data center and OCI. Then to use OCI CLI command to upload database backups to OCI Object Storage Archive tier as the final destination.
B. Use OCI Storage Gateway to transfer the backup files to OCI Object Storage Archive tier as the final destination.
C. Setup a FastConnect connection between on-premises data center and OCI. Then to use OCI CLI command to upload database backups to OCI Object Storage Standard tier as the final destination.
D. Use OCI Storage Gateway to transfer the backup files to OCI Object Storage Standard tier as the final destination.
You are designing the network infrastructure for an application consisting of a web server (server-1) and a Domain Name Server (server-2) running in two different subnets inside the same Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access server-1 from the internet and server-2 from your customer's on-premises network. The on-premises network is connected to your VCN over a FastConnect virtual circuit. How should you design your routing configuration to meet these requirements?
A. Configure a single routing table with two set of rules: one that has route to internet via an Internet Gateway and another that propagates specific routes for the on-premises network via a Dynamic Routing Gateway. Don't associate this routing table with any of the subnets in the VCN.
B. Configure a single routing table with two set of rules: one that has route to internet via an Internet Gateway and another that propagate specific routes to the on-premises network via a Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.
C. Configure two routing tables: first one with a route to internet via an Internet gateway; associate this route table to the subnet containing server-1 .Configure the second route table to propagate specific routes to the on-premises network via a Dynamic Routing Gateway; associate this route table to subnet containing server-2.
D. Configure two routing tables that have rules to route all traffic via a Dynamic Routing Gateway. Associate the two routing tables with all the VCN subnets.
As part of planning the network design on Oracle Cloud Infrastructure, you have been asked to create an Oracle Cloud Infrastructure Virtual Cloud Network (VCN) with 3 subnets, one in each Availability Domain. Each subnet needs to have a minimum of 64 usable IP addresses. What is the smallest subnet and VCN size you should use to implement this design? The requirements are static, so no growth is expected.
A. 122 for the VCN; 124 for the subnets
B. /23 for the VCN; /25 for the subnets
C. /24 for the VCN; /24 for the subnets
D. /22 for the VCN; /25 for the subnets
You have deployed art application server irt a private Subnet irt your virtual cloud network (VCN). For the database, you have provisioned an Autonomous Transaction Processing (ATP) serverless instance. However, you are unable to connect to the database instance from your application server. Which two steps would you need to enable this connectivity?
A. Add an internet gateway to your VCN and add a route rule to your private subnet route table. CIDR: 0.0.0.0/0 Target: Internet Gateway
B. Add a remote peering connection from your VCN to the ATP VCN
C. Add a stateful egress rule to the security list associated with your private subnet. Destination CIDR: 0.0.0.0/0 Protocols: All Protocols
D. Create a NAT Gateway and add the following route rule to the route table of private subnet. CIDR: 0.0.0.0/0 Target: NAT Gateway
You have been asked to create a mobile application which will be used for submitting orders by users of a popular E-Commerce site. The application is built to work with Autonomous Transaction Processing -Serverless (ATP-S) database as the backend and HTML5 on Oracle Application Express as the front end. During the peak usage of the application you notice that the application response time is very slow. ATP-S database is deployed with 3 CPU cores and 1 TB of memory. Which two options are expensive or impractical ways to improve the application response times?
A. Identify the maximum memory capacity needed for peak times and scale the memory for the ATP- S database to that number. ATP-S will scale the memory down when not needed.
B. Use the Machine Learning (ML) feature of the ATP-S database iteratively to tune the SQL queries used by the application.
C. Scale up CPU core count and memory during peak times.
D. Enable auto scaling for CPU cores on ATP-S database.
E. Identify the maximum CPU capacity needed for peak times and scale the CPU core count for the ATPS database to that number. ATP-S will scale the CPU core count down when not needed.
An E-Commerce company wants to deploy their web application for Oracle Database on Oracle Cloud Infrastructure (OCIJ DB Systems. In compliance with the business continuity program of the business, they need to provide a Recovery Point Objective (RPO) of 1 hour and a Recovery Time Objective (RTO) of 5 minutes. The web application should be highly available within the region and meet the RTO and RPO requirements in case of a region outage. Which approach is the most suitable and cost effective configuration for this scenario?
A. Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.
B. Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard.
C. Deploy an Autonomous Transaction Processing (Serverless) database in one region and replicate it to an Autonomous Transaction Processing (Serverless) database in another region using Oracle GoldenGate.
D. Deploy a 1 node VM Oracle database in one region. Manually Configure a Recovery Manager (RMAN) database backup schedule to take hourly database backups. Asynchronously copy the database backups to object storage in another OCI region. If the primary OCI region is unavailable, launch a new 1 node VM Database in the other OCI region and restore the production database from the backup.
You have configured backups for your Oracle Cloud Infrastructure (OCI) 2-node RAC DB systems on virtual machines. In the console, the database backup displays a Failed status. Which of the following options is the most likely reason for this backup issue?
A. The master key stored in OCI Key Management for encryption and decryption of data in the database is not accessible to the backup service.
B. The auth token being used by the Object Store Swift endpoint is incorrect.
C. The allocated storage on the OCI File Storage service file system attached with the database is full.
D. The RMAN backup agent is not compatible with the version of database being used.
A customer has a Virtual Machine instance running in their Oracle Cloud Infrastructure tenancy. They
realized that they wrongly picked a smaller shape for their compute instance. They are reaching out to you

A. OCI doesn't allow such an operation.
B. Change the shape of instance without reboot, but stop all the applications running on instance beforehand to prevent data corruption.
C. Delete the running instance and spin up a new instance with the desired shape.
D. Change the shape of the virtual machine instance using the Change Shape feature available in the
console.
