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 taint nodes """"all node""role.kubernetes.io/master"" 3. Delete the old node pool
• B. 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
• C. 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
• D. 1. Shutdown the worker nodes 2. Create a new node pool 3. Manually schedule the pods on the newly built node pool

An organization has its IT infrastructure in a hybrid setup with an on-premises environment and an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) in the us-phonix-1 region. The on-premise applications communications with compute instances inside the VPN over a hardware VPN connection. They are looking to implement an Intrusion detected and Prevention (IDS/IPS) system for their OCI environment. 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?

• A. Configure autoscaling on a compute Instance pool and set vNIC to promiscuous mode to called traffic across the vcn and send it IDS/IPS platform for inspection.
• B. Configure each host with an agent that collects all network traffic and sends that traffic to the IDS/IPS platform to inspection
• C. Set up an OCI Private Load Balance! and configure IDS/IPS related health checks at TCP and/or HTTP level to inspect traffic
• D. There Is no need to implement an IPS/IDS system as traffic coming over IPSec VPN tunnels Is already encrypt

You are helping a customer troubleshoot a problem. The customer has several Oracle Linux servers in a private subnet within a Virtual Cloud Network (VCN). The servers are configured to periodically communicate to the Internet to get security patches for applications Installed on them.
The servers are unable to reach the Internet. An Internet Gateway has been deployed In the public subnet in the VCN and the appropriate routes are configured in the Route Table associated with the public subnet.
Based on cost considerations, which option will fix this Issue?

• A. Create another Internet Gateway and configure it as route target for the private subnet.
• B. Create a NAT gateway in the VCN and configure the NAT gateway as the route target for the private subnet.
• C. Implement a NAT instance In the public subnet of the VCN and configure the NAT instance as the route target for the private subnet.
• D. Create a Public Load Balancer In front of the servers and add the servers to the Backend Set of the Public Load Balancer.

A company has an urgent requirement to migrate 300 TB of data to Oracle Cloud Infrastructure (OCI) In two weeks. Their data center has been recently struck by a massive hurricane and the building has been badly damaged, although still operational. They have a 100 Mbps Internet line but the connection is Intermittent due to the damages caused to the electrical grid in this scenario, what is the most effective service to use to migrate the data to OCI given the time constraints?

• A. Setup a hybrid network by launching aIGbpsFastConnect virtual circuit between your data center and OCI. Use OCI Object storage multipart upload tool to automate the migration of your data to OCI.
• B. Setup a OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI using OCI Storage Gateway Cloud Sync tool.
• C. Upload the data to OCI using OCI Object Storage multipart upload tool.
• D. Use multiple OCI Data Transfer Appliances to transfer data to OCI.
• E. Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI.

A cost conscious fashions design company which sells bags, clothes, and other luxury items has recently decided to more all of the their on-premises infrastructure Oracle Cloud Infrastructure (OCI), One of their on-premises application is running on an NGINX server and the Oracle Database is running in a 2 node Oracle Real Application Clusters (RAC) configuration.
Based on cost considerations, what is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?

• A. Launch a compute Instance and run an NGINX server to host the application. Deploy Exadata Quarter Rack, enable automatic backups and import the database using Oracle Data Pump.
• B. Launch a Compute instance and run a NGINX Server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled Import the on premises database to OCI VM DB Systems using data pump and then enable automatic backup- Also, enable Oracle Data Guard on the database server
• C. Launch a compute Instance and run a NGINX server to host the application. Deploy a 2 node VM DB Systems with oracle RAC enabled import the on premises database to OCI VM DB Systems using oracle Data Pump and then enable automatic backups.
• D. Launch a compute Instance for both the NGINX application server and the database server. Attach block volumes on the database server compute instance and enable backup policy to backup the block volumes.
