You are a cloud architect at a financial organization. The development team is tasked with creating a cloud native application to be hosted on Oracle Cloud Infrastructure (OCI). The development team has followed a microservices-based approach and created containerized images of the cloud-native application and pushed them to OCI Registry (OCIR).
How can you deploy a load balanced application to your OCI Container Engine for Kubernetes (OKE) cluster using these images?
A. Create a load balancer using the OCI load balancer service, add the load balancer service IP in the manifest file, add the location of the docker image to the manifest file, and deploy the manifest file.
B. Create a named secret, add the secret to the manifest file, add the location of the docker image to the manifest file, add the service of type LoadBalancer in the manifest file, and deploy the manifest file.
C. Create an auth token, add the auth token to the manifest file, add the location of the docker image to the manifest file, add the service of type LoadBalancer in the manifest file, and deploy the manifest file.
D. Add the location of the docker image to the manifest file, deploy the manifest file. All applications are load-balanced by default in OKE
You developed a microservices based application that runs on Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). Your security team wants to use SSL termination for this application. What should you do to create a secure SSL termination for this application using fewest steps?
A. Create a self-signed certificate and it's corresponding key. Create a Kubernetes secret using the certificate and the key. Then add these an notations to the Kubernetes service: annotations: service.beta.kubernetes.io/oci-load-balancer-ssl-ports: "443" service.beta.kubernetes.io/oci-load-balancer-security-list-management-mode:"Frontend"
B. Generate a self-signed certificate using Let's Encrypt. Use that certificate on OCI Load Balancer. Create the Kubernetes service usingthis load balancer.
C. Add these annotationsto the Kubernetes service: annotations: service.beta.kubernetes.io/oci-load-balancer-ssl-ports: "443" service.beta.kubernetes.io/oci-load-balancer-ssl-secret-key: ssl-secret-key
D. Create a self-signed certificate and it's corresponding key. Create a Kubernetes secret using then add these annotationsto the Kubernetes service. Service.beta.kubernete.io/oci-load-balancer-ssl-ports: "443" Service.beta.kubernete.io/oci-load-balancer-tls-secret:SSL-CERTIFICATE-SECRET
Which three scenarios are suitable for the use of Oracle Cloud Infrastructure (OCI) Autonomous Transaction Processing - Serverless (ATP-S) deployment? (Choose three.)
A. A well-established, online auction marketplace is running an application where there is database usage 24x7, but also has peaks of activity that are hard to predict. When the peaks happen, the total activities may reach 3 times the normal activity level.
B. A midsize company is considering migrating its legacy on-premises MongoDB database to Oracle Cloud Infrastructure (OCI). The database has significantly higher workloads on weekends than weekdays.
C. A manufacturing company is running Oracle E-Business Suite application on-premises. They are looking to move this application to OCI and they want to use a managed database offering for their database tier.
D. A developer working on an internal project needs to use a database during work hours but doesn't need it during nights or weekends. The project budget requires her to keep costs low.
E. A small startup is deploying a new application for eCommerce and it requires a database to store customers' transactions. The team is unsure of what the load will look like since it is a new application.
You are working on the migration of the web application infrastructure of your company from on-premises to Oracle Cloud Infrastructure. You need to ensure that the DNS cache entries of external clients will not direct them to the on-premises infrastructure after switching to the new infrastructure.
Which of the following options will minimize this problem?
A. Reduce the TTL of the DNS records after the switch.
B. DNS changes propagate fast enough that it is not necessary to take any action.
C. Increase the TTL of the DNS records before the switch.
D. Increase the TTL of the DNS records after the switch.
E. Reduce the TTL of the DNS records before the switch.
Which three options are available to migrate an Oracle database 12.x from an on-premises environment to Oracle Cloud Infrastructure (OCI)?
A. Leverage OCI Storage Gateway asynchronous database migration option.
B. Use Oracle Data Pump Export/Import to migrate the database.
C. Configure RMAN cross-platform transportable tablespace backup sets.
D. Setup OCI schema and data transfer tool with Bare Metal DB Systems as the target.
E. Create a backup of your on-premises database In OCI DB Systems.
A data analytics company has been building its next-generation big data and analytics platform on Oracle Cloud Infrastructure (OCI) in the US East (Ashburn) region. They need a storage service that provides the scale and performance that their big data applications require such as high throughput to compute nodes coupled with low latency file operations.
In addition, they need to allow concurrent connections from multiple compute instances hosted in multiple Availability Domains and want to be able to quickly restore a previous version of the data in case of a need to roll back any major update.
Which option can they use to meet these requirements in the most cost-effective way?
A. Create a file system and mount target in the OCI File Storage service. Mount it into all the required compute instances. Take snapshots of the file system before each update.
B. Create block volume, attach it with read/write, shareable access type to all the required compute instances. Take a backup of the volume before each update.
C. Create an Object Storage bucket with object versioning enabled. Provision a compute instance to host the Storage Gateway and share the bucket via NFS, Mount the NFS into all the required compute instances.
D. Create a connection with the on-premises data center via FastConnect. Mount the shared NFS hosted on-premises.
After performing maintenance on an Oracle Linux compute instance the system is returned to a running state You attempt to connect using SSH t to do so. You decide to create an instance console connection to troubleshoot the issue.
Which three tasks would enable you to connect to the console connection and begin troubleshooting?
A. Use SSH to connect to the public: IP address of the compute Instance and provide the console connection OCID as the username.
B. edit the Linux boot menu to enable access to console.
C. Use SSH to connect to the service endpoint of the console connection service
D. Reboot the compute instance using the Oracle Cloud Infrastructure (OCI) Management Console
E. Upload an API signing key for console connection authentication.
F. Stop the compute Instance using the Oracle cloud Infrastructure (OCI) Command Line interface (CLI).
Many development engineers are deploying new instances as part of their projects in Oracle Cloud Infrastructure tenancy, but majority of these instances have not been tagged. You as an administrator of this tenancy want to enforce tagging to identify owners who are launching these instances.
Which option below should be used to implement this requirement?

B. Create a default tag for each compartment which ensure appropriate tags are allowed at resource creation.
C. Create tag variables for each compartment to automatically tag a resource with user name.
D. Create an IAM policy to automatically tag a resource with the usemame.
You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use 'Volume Groups' feature. The Block volume and Compute instances exist in different compartments within your tenancy.
Periodically, a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.
What could be the cause?
A. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
B. You are exceeding your volume group backup quota configured.
C. You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.
D. A compute instance with multiple block volumes attached cannot move when a compartment is moved.
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.
