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, create a master encryption key in the vault, assign this master 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, import your master encryption key into the vault, generate data encryption key, assign data 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
Answer: A
Explanation:
Explanation
Oracle Cloud Infrastructure Vault lets you centrally manage the encryption keys that protect your data and the secret credentials that you use to securely access resources. You can use the Vault service to create and manage the following resources:
Vaults
Keys
Secrets
Vaults securely store master encryption keys and secrets that you might otherwise store in configuration files or in code.
The Vault service lets you create vaults in your tenancy as containers for encryption keys and secrets. If needed, a virtual private vault provides you with a dedicated partition in a hardware security module (HSM), offering a level of storage isolation for encryption keys that's effectively equivalent to a virtual independent HSM.

NEW QUESTION 83
You are a solutions architect for a global health care company which has numerous data centers around the globe. Due to the ever growing data that your company is storing, you were Instructed to set up a durable, cost effective solution to archive you data from your existing on-premises tape based backup Infrastructure to Oracle Cloud Infrastructure (OCI).
What is the most-effective mechanism to Implement this requirement?
- A. Setup fastConnect to connect your on premises network to your OCI VCN and use rsync tool to copy your data to OCI Object Storage Archive tier.
- B. Use the File Storage Service in OCI and copy the data from your existing tape based backup to the shared file system
- C. Setup an on premises OCI Storage Gateway which will back up your data to OCI Object Storage Archive tier.(Correct)
- D. Setup an on-promises OCI Storage Gateway which will back up your data to OCI Object Storage Standard
- E. Setup an on premises OCI Storage Gateway which will back up your data to OCI object Storage Standard tier. Use Object Storage life cycle policy management to move any data older than 30 days from Standard to Archive tier.
Answer: C
Explanation:
Oracle Cloud Infrastructure offers two distinct storage tiers for you to store your unstructured data. Use the Object Storage Standard tier for data to which you need fast, immediate, and frequent access. Use the Archive Storage service's Archive tier for data that you access infrequently, but which must be preserved for long periods of time. Both storage tiers use the same manageable resources (for example, objects and buckets). The difference is that when you upload a file to Archive Storage, the object is immediately archived. Before you can access an archived object, you must first restore the object to the Standard tier.
you can use Storage Gateway to move files to Oracle Cloud Infrastructure Archive Storage as a cost effective backup solution. You can move individual files and compressed or uncompressed ZIP or TAR archives. Storing secondary copies of data is an ideal use case for Storage Gateway.

NEW QUESTION 88
You work for a German company as the Lead Oracle Cloud Infrastructure architect. You have designed a highly scalable architecture for your company's business critical application which uses the Load Balancer service auto which uses the Load Balancer service, autoscaling configuration for the application servers and a 2 Node VM Oracle RAC database. During the peak utilization period of the- application yon notice that the application is running slow and customers are complaining. This is resulting in support tickets being created for API timeouts and negative sentiment from the customer base.
What are two possible reasons for this application slowness?
- A. The Load Balancer configuration is not sending traffic to the listener of the application servers.
- B. Autoscaling configuration for the application servers didn't happen due to service limit breach of the VM shapes used by the application servers
- C. Autoscaling configuration for the application servers didn't happen due to compartment quota breach of the VM shapes used by the application servers.
- D. The Load Balancer doesn't have a Network Security Group to allow traffic to the application servers.
- E. Autoscaling configuration for the application servers didn't happen due to IAM policy that's blocking access to the application server compartment
Answer: B,C
Explanation:
Autoscaling
Autoscaling enables you to automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.
Prerequisites
- You have an instance pool. Optionally, you can attach a load balancer to the instance pool. For steps to create an instance pool and attach a load balancer, see Creating an Instance Pool.
- Monitoring is enabled on the instances in the instance pool. For steps to enable monitoring, see Enabling Monitoring for Compute Instances.
- The instance pool supports the maximum number of instances that you want to scale to. This limit is determined by your tenancy's service limits.
About Service Limits and Usage
When you sign up for Oracle Cloud Infrastructure, a set of service limits are configured for your tenancy.
The service limit is the quota or allowance set on a resource. For example, your tenancy is allowed a maximum number of compute instances per availability domain. These limits are generally established with your Oracle sales representative when you purchase Oracle Cloud Infrastructure.
Compartment Quotas
Compartment quotas are similar to service limits; the biggest difference is that service limits are set by Oracle, and compartment quotas are set by administrators, using policies that allow them to allocate resources with a high level of flexibility.
NEW QUESTION 89
An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two
- A. Enabling auto scaling does not change the concurrency and parallelism settings
- B. The maximum CPU cores that will be automatically allocated for this database is 16 CPUs
- C. Auto scaling also scales IO throughput linearly along with CPU
- D. The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling
Answer: A,C
Explanation:
Explanation
Auto scaling is enabled by default when you create an Autonomous Database instance or you can use Scale Up/Down on the Oracle Cloud Infrastructure console to enable or disable auto scaling.
With auto scaling enabled the database can use up to three times more CPU and IO resources than specified by the number of OCPUs currently shown in the Scale Up/Down dialog. When auto scaling is enabled, if your workload requires additional CPU and IO resources the database automatically uses the resources without any manual intervention required.
Enabling auto scaling does not change the concurrency and parallelism settings for the predefined services IO throughput depends on the number of CPUs you provision and scales linearly with the number of CPUs.

NEW QUESTION 91
Give this compartment structure:
You want to move a compute instance that is in 'Compute' compartment to 'SysTes-Team'.
You login to your Oracle Cloud Infrastructure (OCI)account and use the 'Move Resource' option.
What will happen when you attempt moving the compute resource?
- A. The move will be successful though Compute Instance and its Public and Private IP address will stay the same. The Compute instance VNIC will need to be moved separately. The Compute instance will still be associated with the original VCN.
- B. The move will be successful though Compute Instance and its Public and Private IP address will stay the same. The Compute instance VNIC will still be associated with the original VCN.
- C. The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the Compute instance can be moved.
- D. The move will be successful though Compute Instance Public and Private IP address changed, and it will be associated to the VCN in target compartment.
Answer: B
Explanation:
Moving Resources to a Different Compartment
Most resources can be moved after they are created. There are a few resources that you can't move from one compartment to another. Some resources have attached resource dependencies and some don't.
Not all attached dependencies behave the same way when the parent resource moves.
For some resources, the attached dependencies move with the parent resource to the new compartment.
The parent resource moves immediately, but in some cases attached dependencies move asynchronously and are not visible in the new compartment until the move is complete.
For other resources, the attached resource dependencies do not move to the new compartment. You can move these attached resources independently.
You can move Compute resources such as instances, instance pools, and custom images from one compartment to another. When you move a Compute resource to a new compartment, associated resources such as boot volumes and VNICs are not moved.
You can move a VCN from one compartment to another. When you move a VCN, its associated VNICs, private IPs, and ephemeral IPs move with it to the new compartment.
NEW QUESTION 92
A large financial services company has used 2 types of Oracle DB Systems. In Oracle Cloud Infrastructure (OCI) to store user dat a. One is running on a VM.Standard2.8 shape and the other on a VM.Standard 2.4 shape.
As business grows, data is growing rapidly on both the databases and performance is also degrading. The company wants to address this problem with a viable and economical solution.
As the solution architect for that company you have suggested that they move their databases to Autonomous Transaction Processing Serverless (ATP-S) database.
Which two factors should you consider before you arrived at that recommendation?
- A. You verified that ATP S supports the database features and options currently being used by the 2 databases.
- B. Confirm that ATP-S allows customers to compress tablespaces to reduce storage costs
- C. Validate that ATP-S will support the storage and processing requirements for the 2 databases over the life cycle of the business applications.
- D. Upon provisioning, ATP-S automatically scales up CPU to meet the application's processing requirements.
Answer: A,C
Explanation:
Not all features present in Oracle Database Enterprise Edition are available in ATP, and some some Oracle Database features are restricted, for example, database features designed for administration are not available. so you need to validate it first, You can find a complete list of the features that are not supported,
https://docs.oracle.com/en/cloud/paas/atp-cloud/atpug/experienced-database-users.html#GUID-58EE6599-6DB4-4F8E-816D-0422377857E5 Also, you must specify the initial storage required for your database but ADB is elastic, so it is possible to grow or shrink your database as needed.
