You are working for a Travel company and your travel portal application is a collection of microservices that run on Oracle Cloud Infrastructure Container Engine for Kubernetes. As per the recent security overview, you have noticed that Oracle has published a newer image of the Operating System used by the worker nodes. You want to make sure that your application doesn't face any downtime but at the same time the worker nodes gets upgraded to the latest version of the Operating System.
What should you do to get this upgrade done without application downtime? (Choose the best answer.)

• A.1. Create a new node pool using the latest available Operating System image. 2. Run kubectl cordon <node name> against all the worker nodes in the old pool to stop any new application pods to get scheduled 3. Run kubectl drain <node name> """"delete""local""data """"force """"ignore""daemonsets to evict any Pods that are running 4. Delete the old node pool
• B.1. Run kubectl cordon <node name> against all the worker nodes in the old pool to stop any new application pods to get scheduled 2. Run kubectl drain <node name> """"delete""local""data """"force """"ignore""daemonsets to evict any Pods that are running 3. Download the patches for the new Operating System image 4. Patch the worker nodes to the latest Operating System image
• C.1. Shutdown the worker nodes 2. Create a new node pool 3. Manually schedule the pods on the newly built node pool
• D.1. Create a new node pool using the latest available Operating System image 2. Run kubectl taint nodes """"all node""role.kubernetes.io/master"" 3. Delete the old node pool

Which of the following is NOT a good use case for using the functionality available in the Oracle Cloud Infrastructure (OCI) Events service?

• A.Trigger a notification when a function completes its execution.
• B.Triggers Function using Oracle Functions when new files are uploaded in an OCI Object Storage bucket.
• C.Publish a notification when long lived tasks complete, such as OCI Autonomous Database backup completion.
• D.Capture Monitoring Alarms and invoke Autoscaling of compute instances.
• E.Publish all events in a specific compartment to Oracle Streaming service for later analysis.

You are a solutions architect for a global health care company which has numerous data centers around the globe. Due to the ever growing data that your company is storing, you were Instructed to set up a durable, cost effective solution to archive you data from your existing on-premises tape based backup Infrastructure to Oracle Cloud Infrastructure (OCI).
What is the most-effective mechanism to Implement this requirement?

• A.Setup an on premises OCI Storage Gateway which will back up your data to OCI object Storage Standard tier. Use Object Storage life cycle policy management to move any data older than 30 days from Standard to Archive tier.
• B.Use the File Storage Service in OCI and copy the data from your existing tape based backup to the shared file system
• C.Setup an on-promises OCI Storage Gateway which will back up your data to OCI Object Storage Standard
• D.Setup fastConnect to connect your on premises network to your OCI VCN and use rsync tool to copy your data to OCI Object Storage Archive tier.
• E.Setup an on premises OCI Storage Gateway which will back up your data to OCI Object Storage Archive tier.(Correct)

An Oracle Cloud Infrastructure (OCI) Public Load Balancer's SSL certificate is expiring soon. You noticed the Load Balancer is configured with SSL Termination only. When the certificate expires, data traffic can be interrupted and security compromised.
What steps do you need to take to prevent this situation?

• A.Add the new SSL certificate to the Load Balancer, update backend servers to work with a new certificate and edit listeners so they can use the new certificate bundle.
• B.Add the new SSL certificate to the Load Balancer, update listeners and backend sets so they can use the new certificate bundle.
• C.Add the new SSL certificate to the Load Balancer and update backend servers to use the new certificate bundle.
• D.Add the new SSL certificate to the Load Balancer and update listeners to use the new certificate bundle.
• E.Add the new SSL certificate to the Load Balancer and implement end to end SSL so it can encrypt the traffic from clients all the way to the backend servers.

You are part of a project team working in the development environment created in OCI. You have realized that the CIDR block specified for one of the subnet in a VCN is not correct and want to delete the subnet. While deleting you are getting an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet.
Which of the following action you will take to troubleshoot this issue?

• A.Copy and Paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC
• B.Use OCI CLI to call "GetVnic" operation to find out the parent resource of the VNIC
• C.Use OCI CLI to delete the subnet using --force option
• D.Use OCI CLI to delete the VNIC first and then delete the subnet
