By copying block volume backups to another region at regular intervals, it makes it easier for you 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 '

• A.Allow group VolumeAdmins to inspect volumes in tenancy
• B.Allow group VolumeAdmins to manage volume-family In tenancy
• C.Allow group VolumeAdmins to use volumes in tenancy
• D.Allow group VolumeAdmins to copy volume' backups in tenancy

You are working as a solution architect with a global automotive provider who is looking to create a multi-cloud solution. They want to run their application tier in Microsoft Azure while utilizing the Oracle DB Systems in the Oracle Cloud Infrastructure (OCI).
What is the most-fault tolerant and secure solution for this customer? (Choose the best answer.)

• A.Create an encrypted, Virtual Private Network connection between the Microsoft Azure Virtual Network that contains the application tier and the OCI Virtual Cloud Network (VCN) that contains the Oracle Databases.
• B.Create a FastConnect virtual circuit with Microsoft Azure as the provider to establish a private interconnect between the application tier running in the Azure Virtual Network and the OCI VCN that contains the Oracle Databases.
• C.Deploy the Oracle database system into a public subnet in your VCN and assign a public IP address. Connect your application tier running in Azure to the public IP address of the database system over the internet.
• D.Use an OCI Virtual Cloud Network remote peering connection to create a remote network connection between the application tier running in Microsoft Azure Virtual Network and Oracle Databases running in the OCI Virtual Cloud Network (VCN).

You developed a microservices based application that runs on Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). It has multiple endpoints that needs to be exposed to the public internet.
What Is the most cost-effective way to expose multiple application endpoints without adding complexity to the application?

• A.Use NodePort service type in Kubernetesfor each of yourservice endpointand use node's public IP address to acccess the applications.
• B.Use separate load balancerinstancefor each service but use the 100 Mbps loadbalanceroption.
• C.Use clusterlP service type in Kubernetesfor each of yourservice endpointand use a load balancerto expose the endpoints.
• D.Deploy an Ingress controllerand use it to expose each endpointwith its own routing endpoint.

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 to help them fix the issue.
Which of the below options is best recommended to suggest to the customer?

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

You are designing the network infrastructure for two application servers: appserver-1 and appserver-2 running in two different subnets inside the same Virtual Cloud Network (VCN) Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access appserver-1 from the internet and appserver-2 from the 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 two routing table (Route table-1 Route Table-2) that have rule to route all traffic via the Dynamic Routing Gateway (DRG) Associate the two routing tables with all the VCN subnets.
• B.Configure two routing tables: Route Table-1 that has a route to internet via the Internet gateway. Associate this route table to the subnet containing appserver-1. Route Table-2 that propagate specific routes for the on-premises network via the Dynamic Routing Gateway (DRG) Associate this route table to subnet containing appserver-2.
• C.Configure a single routing table (Route Table-1) that has two set of rules. One that has route to internet via the internet Gateway and another that propagate specific routes for the on-premise network via the Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.
• D.Configure a single routing table (Routing Table-1) that has two set of rules: one that has route to internet via the Internet Gateway and another that propagates specific routes for the on-premises network via Dynamic Routing Gateway (DRG). Associate the routing table with the VCN.
