A civil engineering company is running an online portal In which engineers can upload there constructions photos, videos, and other digital files.

There is a new requirement for you to implement: the online portal must offload the digital content to an Object Storage bucket for a period of 72 hours. After the provided time limit has elapsed, the portal will hold all the digital content locally and wait for the next offload period.

Which option fulfills this requirement?

A. Create a pre-authenticated URL for the entire Object Storage bucket to read and list the content with an expiration of 72 hours.

B. Create a pre authenticated URL lot each object that Is uploaded to the Object Storage bucket with an expiration of 72 hours.

C. Create a Dynamic Group with matching rule for the portal compute Instance and grant access to the Object Storage bucket for 72 hours.

D. Create a pre authenticated URL for the entire Object Storage bucket to write content with an expiration of 72 hours.

A cloud consultant is working on implementation project on OCI. As part of the compliance requirements, the objects placed in object storage should be automatically archived first and then deleted. He is testing a Lifecycle Policy on Object

Storage and created a policy as below:

[ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes":

"doc"] },

"timeAmount": 5, "timeunit": "DAYS", "isEnabled": true },

{ "name": "Delete_doc", "action": "DELETE", "objectNameFilter": "inclusionPrefixes": [ "doc"]

1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }

What will happen after this policy is applied?

A. All objects with names starting with "doc" will be deleted after 5 days of object creation

B. All the objects having file extension ".doc" will be archived for 5 days and will be deleted 10 days after object creation

C. All the objects having file extension ".doc" will be archived 5 days after object creation

D. All the objects with names starting with "doc" will be archived 5 days after object creation and will be deleted 5 days after archival

You have an application running in Microsoft Azure and want to use Oracle Autonomous Data warehouse (ADW) instance for running business analytics.

How can you build a secure solution for such a use-case?

A. Connect the Oracle ADW in your VCN to the Microsoft Azure VNet over the internet.

B. Create a software VPN connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.

C. Setup an interconnect between OCI and Microsoft Azure using FastConnect and ExpressRoute. Use a Service Gateway in OCI Virtual Cloud Network to provide connectivity to the Oracle ADW instance for the application in Microsoft Azure VNet.

D. Create a software Remote Peering Connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.

Which of the below options is true regarding Oracle Cloud Infrastructure's load balancing service?

A. You can dynamically change the load balancer shape to handle more incoming traffic.

B. The public load balancer applies a floating public IP address to the primary load balancer.

C. When you create a private load balancer, the service requires 2 or more subnets to host both the primary and standby load balancers.

D. A public load balancer is Availability Domain specific in scope.

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. Delete the running instance and spin up a new instance with the desired shape.

B. Change the shape of instance without reboot, but stop all the applications running on instance beforehand to prevent data corruption.

C. Change the shape of the virtual machine instance using the Change Shape feature available in the console.

D. OCI doesn't allow such an operation.

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?

A. Create a predefined tag with tag variables to automatically tag a resource with usemame.

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.

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.

An E-Commerce company wants to deploy their web application for Oracle Database on Oracle Cloud Infrastructure (OCIJ DB Systems. In compliance with the business continuity program of the business, they need to provide a Recovery Point Objective (RPO) of 1 hour and a Recovery Time Objective (RTO) of 5 minutes. The web application should be highly available within the region and meet the RTO and RPO requirements in case of a region outage.

Which approach is the most suitable and cost effective configuration for this scenario?

A. Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.

B. Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard.

C. Deploy an Autonomous Transaction Processing (Serverless) database in one region and replicate it to an Autonomous Transaction Processing (Serverless) database in another region using Oracle GoldenGate.

D. Deploy a 1 node VM Oracle database in one region. Manually Configure a Recovery Manager (RMAN) database backup schedule to take hourly database backups. Asynchronously copy the database backups to object storage in another OCI region. If the primary OCI region is unavailable, launch a new 1 node VM Database in the other OCI region and restore the production database from the backup.
