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 write content with an expiration of 72 hours.
• B.Create a Dynamic Group with matching rule for the portal compute Instance and grant access to the Object Storage bucket for 72 hours.
• C.Create a pre-authenticated URL for the entire Object Storage bucket to read and list the content with an expiration of 72 hours.
• D.Create a pre authenticated URL lot each object that Is uploaded to the Object Storage bucket with an expiration of 72 hours.

Your organization is planning on using Oracle Cloud Infrastructure (OCI) File Storage Service (FSS). You will be deploying multiple compute instance in Oracle Cloud Infrastructure (OCI) and mounting the file system to these compute instances. The file system will hold payment data processed by a Database instance and utilized by compute instances to create a overall inventory report. You need to restrict access to this data for specific compute instances and must be allowed/blocked per compute instance's CIDR block.
Which option can you use to secure access?

• A.Create and configure OCI Web Application Firewall service with built in DNS based intelligent routing.
• B.Use stateless Security List rule to restrict access from known IP addresses only.
• C.Create a new VCN security list, choose SOURCE TYPE as Service and SOURCE SERVICE as FSS. Add stateless ingress and egress rules for specific P address and CIDR blocks.
• D.Use 'Export option' feature of FSS to restrict access to the mounted file systems.

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 a NAT gateway in the VCN and configure the NAT gateway as the route target for the private subnet.
• B.Create another Internet Gateway and configure it as 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 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.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.Change the shape of instance without reboot, but stop all the applications running on instance beforehand to prevent data corruption.

An online Stock trading application is deployed to multiple Availability Domains in the us phoenix-1 region. Considering the high volume of transactions that the trading application handles, the company has hired you to ensure that the data stored by the application available, and disaster resilient. In the event of failure, the Recovery lime Objective (UK)) must be less than 2 hours to meet regulator requirements.
Which Disaster Recovery strategy should be used to achieve the RTO requirement In the event of system failure?

• A.Configure hourly block volumes backups through the Storage Gateway service.
• B.Configure hourly block volumes backups using the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI)
• C.Configure your application to use synchronous master slave data replication between Availability Domains.
• D.Store hourly block volumes backup to NVMe device under a compute instance and generate a custom Image every 5 minutes.
