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.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.
• C.Use OCI Storage Gateway to transfer the backup files to OCI Object Storage Archive 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.

A retail company has several on-premises data centers which span multiple geographical locations. They plan to move some of their applications from on-premises data centers to Oracle Cloud Infrastructure (OCI). For these applications running in OCI, they still need to interact with applications running on their on-premises data centers to Oracle Cloud Infrastructure (OCI). for these applications running in OCI. they still need to interact with applications running on their on-premises data centers. These applications require highly available, fault-tolerant network connections between on premises data centers and OCI.
Which option should you recommend to provide the highest level of redundancy?

• A.Use FastConnect private peering only to ensure secure access from your data center to Oracle Cloud Infrastructure
• B.Oracle cloud Infrastructure provides network redundancy by default so that no other operations are required
• C.Set up both IPSec VPN and FastConnect to connect your on premises data centers to Oracle Cloud Infrastructure.
• D.Set up a single IPSec VPN connection (rom your data center to Oracle Cloud Infrastructure since It is cost effective
• E.If your data centers span multiple, geographical locations, use only the specific IP address as a static route for the specific geographical location

A hospital in Austin has hosted its web based medical records portal entirely In Oracle cloud Infrastructure (OCI) using Compute Instances for its web-tier and DB system database for its data tier. To validate compliance with Health Insurance Portability and Accountability (HIPAA), the security professional to check their systems it was found that there are a lot of unauthorized coming requests coming from a set of IP addresses originating from a country in Southeast Asia.
Which option can mitigate this type of attack?

• A.Block the attacking IP address by creating by Network Security Group rule to deny access to the compute Instance where the web server Is running
• B.Block the attacking IP address by implementing a OCI Web Application Firewall policy using Access Control Rules
• C.Block the attacking IP address by creating a Security List rule to deny access to the subnet where the web server Is running
• D.Mitigate the attack by changing the Route fable to redirect the unauthorized traffic to a dummy Compute instance

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 the root compartment as follows: Allow group admins to manage subnets in compartment Finance:A:X
• B.Define a policy in compartment HR as follows: Allow group networkadmins to manage subnets in compartment C:X.
• C.Define a policy in the root compartment as follows: Allow group admins to read subnets in compartment HR:C:X
• D.Define a policy in compartment C as follows: Allow group networkadmins to read subnets in compartment X

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.Scale up CPU core count and memory during peak times.
• B.Identify the maximum CPU capacity needed for peak times and scale the CPU core count for the ATP-S database to that number. ATP-S will scale the CPU core count down when not needed.
• C.Enable auto scaling for CPU cores on ATP-S database.
• D.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.
• E.Use the Machine Learning (ML) feature of the ATP-S database iteratively to tune the SQL queries used by the application.
