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. 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.
• B. 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.
• 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 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.

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?

• A. Configure Control Rules to send traffic to multiple web servers
• B. Configure multiple origin servers
• C. Configure auto scaling policy and it to WAF instance.
• D. Configure new rules based on now vulnerabilities and mitigations

An upcoming e-commerce company has deployed their online shopping application on OCI. The application was deployed on compute instances with autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend.
In order to promote their e-commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints.
What could be two possible reasons for this situation?

• A. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.
• B. As part of autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change
• C. The autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room of scaling
• D. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation

You are trying to delete a compartment. The delete operation is falling and you need to troubleshoot the problem.
Which step should NOT be considered when troubleshooting this issue?

• A. Verify that there are no policies In the root compartment that reference the compartment you are trying to delete.
• B. Search for resources in the compartment for each region that your tenancy is subscribed to.
• C. Make sure you have at least one more compartment in your tenancy other than the root compartment.
• D. Verify that you have removed all resources from the compartment.

A retail company has recently adopted a hybrid architecture. They have the following requirements for their end-to-end Connectivity model between their on-premises data center and Oracle Cloud Infrastructure (OC1) region
* Highly available connection with service level redundancy
* Dedicated network bandwidth with low latency
Which connectivity setup is the most cost effective solution for this scenario?

• A. Setup FastConnect virtual circuit as your primary connection, and an IPSec VPN as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes through FastConnect virtual circuit, and more specific routes through the backup IPSec VPN path.
• B. Setup FastConnect virtual circuit as your primary connection, and a second FastConnect virtual circuit as a backup connection. Use separate edge devices in your FastConnect physical connectivity is redundant Use a single edge device in your on premises data center for each connection From yc device, advertise more specific routes via primary FastConnect virtual circuit, and less specific routes through t backup FastConnect circuit.
• C. Setup IPsec VPN as your primary connection, and a FastConnect virtual circuit as a backup connection. Use separate edge devices in your on-premises data canter for each connection from your edge devices, advertise more specific routes IPSec VPN, and specific routes through the backup FastConnect virtual circuit.
• D. Setup IPSec VPN as your primary connection, and a second IPSec VPN as a backup connection. Use separate edge devices in your on p data center for each connection. From your edge devices, advertise more specific routes via primary IPSec VPN. and less specific rod the backup IPSec VPN.
