A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They have decided to use both containers and servers technologies to run these application instances.
Which option should you recommend to build this new platform?
A. Install a kubernetes cluster on OCI and use OCI event service.
B. Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.
C. Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.
D. Use OCI functions, OCI object storage and OCI event service.
Correct Answer: B
Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions- as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.

Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy.
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.
Correct Answer: B
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.
