This platform should have the ability to scale to thousands of compute of instances running inside the VCN.
How should they architect their solution on OCI to achieve this goal?
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?
You are working as a solution architect for an online retail store to create 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 Spelunk IP addresses 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 create up to 15 Instances during peak traffic demand, which are launched In VCN private in VCN private subnets and attached to an OCI public Load Balancer. Upon user payment, the portal connects to the payment service over the Interne! to complete the transaction
What solution can you implement to make sure that all compute Instances can connect to the third party system to process the payments aw peak traffic demand?
You are trying to delete a compartment. The delete operation is falling and you need to troubleshoot the problem.
Which step should NOT be considered when troubleshooting this issue?
An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company.
