An E-commerce company which sells computers, tablets, and other electronics items has recently decided to move all of their on-premises infrastructure to 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.
They cannot afford to have any application down time when they do the migration.
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 an 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.
• B.Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Setup Oracle GoldenGate to synchronize data from their on-premises database to OCIVM Database. Export and Import the on-premises database to OCIVM DB Systems using Oracle Data Pump, apply the GoldenGate trail files to sync up the OCI database with the on-premises database. Enable automatic backups for the OCIVM database and then cutoverthe application from on-premises to OCI.
• C.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.
• D.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.

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.Create an OCI Object Storage Standard tier bucket Configure a lifecycle policy to archive any object that Is older than 365 days
• B.Provision a FastConnect link to the closest OCI region and configure a private peering virtual circuit.
• 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.Create an OCI Object Storage Standard tier bucket. Configure a lifecycle policy to delete any object that is older than 7 years
• E.Provision a FastConnect link to the closest OCI region and configure a public peering virtual circuit

Your company has recently deployed a new web application that uses Oracle functions Your manager Instructed you to Implement major manage your systems more effectively. You know that Oracle functions automatically monitors functions on your behalf reports metrics through Service Metrics.
Which two metrics are collected and made available by this feature?

• A.length of time a function runs
• B.amount of CPU used by a function
• C.number of concurrent connections
• D.number of times a function is invoked
• E.number of times a function is removed

A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They have decided to use both containers and servers technologies to run these application instances.
Which option should you recommend to build this new platform?

• A.Use OCI functions, OCI object storage and OCI event service.
• B.Install a kubernetes cluster on OCI and use OCI event service.
• C.Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.
• D.Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.

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