Oracle 1z0-997-20 Exam Practice Questions (P. 4)

You work as a solutions architect for an online retail store creating a portal to allow the users to pay for their groceries using credit cards. Since the application is not fully compliant with the Payment Card Industry Data Security Standard (PCI DSS), your company is looking to use a third-party payment service to process credit card payments.
The third-party service allows a maximum of 5 public IP addresses at a time. However, your website is using Oracle Cloud Infrastructure (OCI) Instance Pool Auto
Scaling policy to create up to 15 instances during peak traffic demand, which are launched in VCN private subnets and attached to an OCI public Load Balancer.
Upon user payment, the portal connects to the payment service over the Internet to complete the transaction
What solution can you implement to make sure that all 15 compute instances can connect to the third party system to process the payments during peak traffic demand? (Choose the best answer.)

You are developing a Serverless function for your company's IoT project. This function should access Oracle Cloud Infrastructure (OCI) Object Storage to store some files. You choose Oracle Functions to deploy this function on OCI. However, your security team doesn't allow you to carry any API Token or RSA Key to authenticate the function against the OCI API to access the Object Storage.
What should you do to get this function to access OCI Object Storage without carrying any static authentication files? (Choose the best answer.)

You work for a retail company and they developed a Microservices based shopping application that needs to access Oracle Autonomous Database from the application. As an Architect, you have been tasked to treat all of the application components as Kubernetes native objects, such as the microservices, Oracle
Autonomous database, Kubernetes services, etc.
What should you do to make sure that you can use Kubernetes constructs to manage the life cycle of the application components, including Oracle Autonomous
Database? (Choose the best answer.)

A large London based eCommerce company is running Oracle DB Systems Virtual Machine RAC database on Oracle Cloud Infrastructure (OCI) for their eCommerce application in the uk-london-1 region. They are currently taking automatic backups of the database, as configured during the database provisioning activity. They are launching a new product soon, which is expected to sell in large quantities all over the world.
The application architecture should have minimal cost, no data loss, no performance impacts during the database backup windows and should have minimal downtime.
What is the most efficient and cost-effective mechanism of modifying the database deployment architecture to meet these application goals? (Choose the best answer.)

Your organization is using Oracle Cloud Infrastructure (OCI) and wants to setup a disaster recovery plan by copying block volume backups to another region at regular intervals. This makes it easier to rebuild applications and data in the destination region if a region wide disaster occurs in the source region.
Which IAM Policy statement allows the VolumeAdmins group to copy volume backups between regions? (Choose the best answer.)
