質問 1：
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. Validate that ATP-S will support the storage and processing requirements for the 2 databases over the life cycle of the business applications.
B. Upon provisioning, ATP-S automatically scales up CPU to meet the application's processing requirements.
C. Confirm that ATP-S allows customers to compress tablespaces to reduce storage costs
D. You verified that ATP S supports the database features and options currently being used by the 2 databases.
正解：A,D

質問 2：
A cost conscious fashions design company which sells bags, clothes, and other luxury items has recently decided to more all of the their on-premises infrastructure Oracle Cloud Infrastructure (OCI), One of their on-premises application is running on an NGINX server and the Oracle Database is running in a 2 node Oracle Real Application Clusters (RAC) configuration.
Based on cost considerations, what is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?
A. Launch a Compute instance and run a NGINX Server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled Import the on premises database to OCI VM DB Systems using data pump and then enable automatic backup- Also, enable Oracle Data Guard on the database server
B. Launch a compute Instance and run a NGINX server to host the application. Deploy a 2 node VM DB Systems with oracle RAC enabled import the on premises database to OCI VM DB Systems using oracle Data Pump and then enable automatic backups.
C. Launch a compute Instance and run an NGINX server to host the application. Deploy Exadata Quarter Rack, enable automatic backups and import the database using Oracle Data Pump.
D. Launch a compute Instance for both the NGINX application server and the database server. Attach block volumes on the database server compute instance and enable backup policy to backup the block volumes.

質問 3：
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 Public and Private IP address changed, and it will be associated to the VCN in target compartment.
B. 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.
C. 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.
D. 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.

質問 4：
Your customer has gone through a recent departmental re structure. As part of this change, they are organizing their Oracle Cloud Infrastructure (OCI) compartment structure to align with the company's new organizational structure.
They have made the following change:
Compartment x Is moved, and its parent compartment is now compartment c.

Policy defined in compartment A: Allow group networkadmins to manage subnets in compartment X Policy defined in root compartment: Allow group admins to read subnets in compartment Finance:A:X After you move the compartment, which two IAM policies would be required to ensure both groups retain the same permissions to compartment X that they had before? (Choose two.)
A. Define a policy in compartment C as follows: Allow group networkadmins to read subnets in compartment X
B. Define a policy in compartment HR as follows: Allow group networkadmins to manage subnets in compartment C:X.
C. Define a policy in the root compartment as follows: Allow group admins to manage subnets in compartment Finance:A:X
D. Define a policy in the root compartment as follows: Allow group admins to read subnets in compartment HR:C:X
正解：B,D

質問 5：
A data analytics company has been building Its now generation big data and analytics platform on Oracle Cloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their big data applications require such as high throughput to compute nodes with low latency file operations in addition, their data needs to be stored redundantly across multiple nodes In a single availability domain and allows concurrent connections from multiple compute Instances hosted on multiple availability domains.
Which OCI storage service can you use to meet i his requirement?
A. Object Storage
B. Archive storage
C. File System Storage
D. Block Volume
正解：C

質問 6：
You are part of a project team working in the development environment created in OCI. You have realized that the CIDR block specified for one of the subnet in a VCN is not correct and want to delete the subnet. While deleting you are getting an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet.
Which of the following action you will take to troubleshoot this issue?
A. Use OCI CLI to delete the VNIC first and then delete the subnet
B. Copy and Paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC
C. Use OCI CLI to delete the subnet using --force option
D. Use OCI CLI to call "GetVnic" operation to find out the parent resource of the VNIC
正解：D

質問 7：
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. Use 'Export option' feature of FSS to restrict access to the mounted file systems.
B. Use stateless Security List rule to restrict access from known IP addresses only.
C. Create and configure OCI Web Application Firewall service with built in DNS based intelligent routing.
D. Create a new VCN security list, choose SOURCE TYPE as Service and SOURCE SERVICE as FSS. Add stateless ingress and egress rules for specific IP address and CIDR blocks.
正解：A

質問 8：
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. 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.
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. 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.
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.
