A large financial company has a web application hosted in their on-premises data center. They are migrating their application to Oracle Cloud Infrastructure (OCI) and require no downtime while the migration is on-going. In order to achieve this, they have decided to divert only 30% of the application works fine, they divert all traffic to OCI.

As a solution architect working with this customer, which suggestion should you provide them?

• Use OCI Traffic management with failover steering policy and distribute the traffic between OC1 and on premises infrastructure.

• Use OCI Traffic management with Load Balancing steering policy and distribute the traffic between OCI and on premises infrastructure.

• Use an OCI load Balancer and distribute the traffic between OCI and on premises infrastructure.

• Use VPN connectivity between on premises Infrastructure and OCI, and create routing tables to distribute the traffic between them.

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?

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

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

• 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.

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

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

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?

• The Load Balancer health check status Indicates critical situation for half of the backend webservers

• All the web servers are too busy and not able to answer any request from users.

• The Database Is down hence users can not access the web site

• The Traffic Management Policy is not set to load Balancer the traffic to the web servers.

• You did not configure a Service Gateway to allow connection between web servers and load Balance

You are building a highly available and fault tolerant web application deployment for your company. Similar application delayed by competitors experienced web site attack including DDoS which resulted in web server failing.

You have decided to use Oracle Web Application Firewall (WAF) to implement an architecture which will provide protection against such attacks and ensure additional configuration will you need to implement to make sure WAF is protecting my web application 24×7.

Which additional configuration will you need to Implement to make sure WAF Is protecting my web application 24×7?

• Configure auto scaling policy and it to WAF instance.

• Configure Control Rules to send traffic to multiple web servers

• Configure multiple origin servers

• Configure new rules based on now vulnerabilities and mitigations

All three Data Guard Configuration are fully supported on Oracle Cloud infrastructure (OCI). You want to deploy a maximum availability architecture (MAA) for database workload.

Which option should you consider while designing your Data Guard configuration to ensure best RTO and PRO without causing any data loss?

• Configure "Maximum Protection" mode which provides zero data loss If the primary database fails

• Configure "Maximum Performance" mode In SYNC mode between two availability domains (same region) which provides, the highest level of data protection that is possible without affecting the performance of the primary database.

• Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.

• Configure ''Maximum Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in SYNC mode between two regions.

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?

• 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.

• 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.

• 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.

• 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

After performing maintenance on an Oracle Linux compute instance the system is returned to a running state You attempt to connect using SSH but are unable to do so. You decide to create an instance console connection to troubleshoot the issue.

Which three tasks would enable you to connect to the console connection and begin troubleshooting?
