You are currently working for a public health care company based in the United Stats. Their existing patient records runs in an on-premises data center and the customer is sending tape backups offsite as part of their recovery planning. You have developed an alternative archival solution using Oracle Cloud Infrastructure (OCI) that will save the company a significant amount of mom on a yearly basis. The solution involves storing data in an OCI Object Storage bucket After reviewing your solution with the customer global Compliance (GRC) team they have highlighted the following security requirements: All data less than 1 year old must be accessible within 2 hour. All data must be retained for at least 10 years and be accessible within 48 hours AH data must be encrypted at rest No data may be transmitted across the public Internet

Which two options meet the requirements outlined by the customer GRC team?

A. Provision a FastConnect link to the closest OCI region and configure a private peering virtual circuit.

B. Create an OCI Object Storage Standard tier bucket Configure a lifecycle policy to archive any object that Is older than 365 days

C. Create a VPN connection between your on premises data center and OCI. Create a Virtual Cloud Network (VCN) along with an OCI Service Gateway for OCI Object Storage.

D. Provision a FastConnect link to the closest OCI region and configure a public peering virtual circuit

E. Create an OCI Object Storage Standard tier bucket. Configure a lifecycle policy to delete any object that is older than 7 years

You are responsible for migrating your on premises legacy databases on 11.2.0.4 version to Autonomous Transaction Processing Dedicated (ATP-D) In Oracle Cloud Infrastructure (OCI). As a solution architect, you need to plan your migration approach. Which two options do you need to implement together to migrate your on premises databases to OCI?

A. Use Oracle Data Guard to keep on premises database always active during migration

B. Retain changes to Oracle shipped privileges, stored procedures or views In the on-premises databases.

C. Use Oracle GoldenGate replication to keep on premises database online during migration.

D. Convert on-premises databases to PDB, upgrade to 19c, and encrypt Migration.

E. Retain all legacy structures and unsupported features (e.g. taw U>Bs) In the onuses databases for migration.

You are trying to delete a compartment. The delete operation is falling and you need to troubleshoot the

problem.

Which step should NOT be considered when troubleshooting this issue?

A. Verify that there are no policies In the root compartment that reference the compartment you are trying to delete.

B. Verify that you have removed all resources from the compartment.

C. Make sure you have at least one more compartment in your tenancy other than the root compartment.

D. Search for resources in the compartment for each region that your tenancy is subscribed to.

You want to automate the processing of new Image files to generate thumbnails. the expected rate is 10

new files every hour.

Which of the following is the most cost effective option to meet this requirement in Oracle Cloud

Infrastructure (OCI)?

A. Upload files to an OCI Object storage bucket. Every time a file is uploaded, an event is emitted. Write a rule to filter these events with an action to trigger a function in Oracle Functions. The function processes the image in the file and stores the thumbnails back in an Object storage bucket.

B. Upload files to an OCI Object storage bucket. Every time a file is uploaded, trigger an event with an action to provision a compute instance with a cloud-init script to access the file, process it and store it back in an Object storage bucket. Terminate the instance using Autoscaling policy after the processing is finished.

C. Build a web application to ingest the files and save them to a NoSQL Database. Configure OCI Events service to trigger a notification using Oracle Notification Service (ONS). ONS invokes a custom application to process the image files to generate thumbnails. Store thumbnails in a NoSQL Database table.

D. Upload all files to an Oracle Streaming Service (OSS) stream. Set up a cron job to invoke a function in Oracle Functions to fetch data from the stream. Invoke another function to process the image files and generate thumbnails. Store thumbnails in another OSS stream.

An insurance company is storing critical financial data in the OCI block volume. This volume is currently encrypted using oracle managed keys. Due to regulatory compliance, the customer wants to encrypt the data using the keys that they can control and not the keys which are controlled by Oracle. What of the following series of tasks are required to encrypt the block volume using customer managed keys?

A. Create a vault, import your master encryption key into the vault, generate data encryption key, assign data encryption key to the block volume

B. Create a master encryption key, create a data encryption key, decrypt the block volume using existing oracle managed keys, encrypt the block volume using the data encryption key

C. Create a vault, create a master encryption key in the vault, assign this master encryption key to the block volume D. Create a master encryption key, create a new version of the encryption key, decrypt the block volume using existing oracle managed keys and encrypt using new version of the encryption key

You are trying to troubleshoot the configuration of your Oracle Cloud Infrastructure (OCI) Load Balancing service. You have a backend HTTP service for which you have created a backend set in the load balancer. You have configured health checks for the backend set. Although the health checks appear good, customers sometimes experience transaction failures. Which of the following options will definitely lead to this problem?

A. You are NOT using regional subnets in your Virtual Cloud Network. With Availability Domain (AD) specific subnet. the compute instances of the backend service running in the subnet have issues when the AD is down.

B. You are using OCI Domain Name System. You have misconfigured the 'A' record with the wrong IP address leading to requests not getting routed correctly.

C. You are using iSCI for block volume attachment to the compute instances in your backed HTTP service. TCP/IP configuration of your block volume attachment is not configured correctly, leading to issues in your backend service.

D. You are running a TCP-level health check against your HTTP service. The TCP handshake can succeed and indicate that the service is up even when the HTTP service has issues.

As part of planning the network design on Oracle Cloud Infrastructure, you have been asked to create an Oracle Cloud Infrastructure Virtual Cloud Network (VCN) with 3 subnets, one in each Availability Domain. Each subnet needs to have a minimum of 64 usable IP addresses. What is the smallest subnet and VCN size you should use to implement this design? The requirements are static, so no growth is expected.

A. 122 for the VCN; 124 for the subnets

B. /23 for the VCN; /25 for the subnets

C. /24 for the VCN; /24 for the subnets

D. /22 for the VCN; /25 for the subnets

A cloud consultant is working on a implementation project on Oracle Cloud Infrastructure (OCI). As part of the compliance requirements, the objects placed in OCI 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:

What will happen after this policy is applied?

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

B. All objects with names starting with "doc" will be deleted after 5 days of 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.
