Which three options are available to migrate an Oracle database 12.x from an on-premises environment to Oracle Cloud Infrastructure (OCI)?

• A.Leverage OCI Storage Gateway asynchronous database migration option.
• B.Use Oracle Data Pump Export/Import to migrate the database.
• C.Configure RMAN cross-platform transportable tablespace backup sets.
• D.Setup OCI schema and data transfer tool with Bare Metal DB Systems as the target.
• E.Create a backup of your on-premises database In OCI DB Systems.

A retail company runs their online shopping platform entirely on Oracle cloud Infrastructure (OCI). This is a 3-tier web application that Includes a Mbps Load Balancer. Virtual Machine Instances for web and an Oracle DB Systems Virtual Machine Due to unprecedented growth, they noticed an Increase in the Incoming traffic to their website and all users start getting 503 (Service Unavailable) errors.
What is the potential problem in this scenario?

• A.You did not configure a Service Gateway to allow connection between web servers and load Balance
• B.The Load Balancer health check status Indicates critical situation for half of the backend webservers
• C.The Traffic Management Policy is not set to load Balancer the traffic to the web servers.
• D.The Database Is down hence users can not access the web site
• E.All the web servers are too busy and not able to answer any request from users.

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.Autoscaling configuration for the application servers didn't happen due to compartment quota breach of the VM shapes used by the application servers.
• B.The Load Balancer doesn't have a Network Security Group to allow traffic to the application servers.
• C.The Load Balancer configuration is not sending traffic to the listener of the application servers.
• D.Autoscaling configuration for the application servers didn't happen due to service limit breach of the VM shapes used by the application servers
• E.Autoscaling configuration for the application servers didn't happen due to 1AM policy that's blocking access to the application server compartment

You are working as a cloud engineer for an IoT startup company which is developing a health monitoring pet collar for dogs and cats. The company collects biometric Information of the pet every second and then sends it to Oracle Cloud Infrastructure (OCI) Your task is to come up with an architecture which will accept and process the monitoring data as well as provide complete trends and health reports to the pet owners. The portal should be highly available, durable, and scalable with an additional feature for showing real time biometric data analytics.
which architecture will help you meet this requirement?

• A.Use OCI Streaming Service to collect the incoming biometric data. Use Oracle Functions to process the date and show the results on a real-time dashboard and store the results lo OCI Object Storage Store the data In OCI Autonomous Data warehouse (ADW) to handle analytics.
• B.Launch an open source Hadoop cluster to collect the Incoming biometrics data Use an Open source Fluentd cluster to analyze the- data me results to OCI Autonomous Transaction Processing (ADW)to handle complex analytics
• C.Create an OCI Object Storage bucket to collect the incoming biometric data from the smart pet collar Fetch the data horn OC\ Object storage to OCI Autonomous Data Warehouse (ADW) every day and run analytics Jobs with it
• D.Use OCI Streaming Service to collect the incoming biometric data. Use an open source Hadoop cluster to analyze the data horn streaming service. Store the results to OCI Autonomous Data warehouse (ADW) to handle complex analytics.

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.Use 'Export option' feature of FSS to restrict access to the mounted file systems.
• 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 P address and CIDR blocks.
