A company has an urgent requirement to migrate 300 TB of data to Oracle Cloud Infrastructure (OCI) In two weeks. Their data center has been recently struck by a massive hurricane and the building has been badly damaged, although still operational. They have a 100 Mbps Internet line but the connection is Intermittent due to the damages caused to the electrical grid in this scenario, what is the most effective service to use to migrate the data to OCI given the time constraints?

A. Setup a OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI using OCI Storage Gateway Cloud Sync tool.

B. Setup a hybrid network by launching aIGbpsFastConnect virtual circuit between your data center and OCI. Use OCI Object storage multipart upload tool to automate the migration of your data to OCI.

C. Use multiple OCI Data Transfer Appliances to transfer data to OCI.

D. Upload the data to OCI using OCI Object Storage multipart upload tool.

E. Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI.

An organization has its mission critical application consisting of multiple application servers and databases

running inside Virtual Cloud Network (VCN) in uk-london-1 region. Their solution architect wants to further

strengthen their architecture by planning for Disaster Recovery (DR) in eu-frankfurt- 1 region.

Which two solutions should their architect keep in mind while designing for DR?

A. A remote VCN peering connection is required to establish secure and reliable connectivity between different VCNs created in uk-london-1 and eu-frankfurt-1 region.

B. rsync utility can be used to asynchronously copy file systems or snapshot data to another region.

C. Load balancer will automatically distribute traffic between both the regions.

D. The RTO is the acceptable timeframe of lost data that application can tolerate.

E. It is not possible to use Active Data Guard to synchronize a database in uk-london-1 region to equivalent database in eu-frankfurt-1 region.

You are tasked with building a highly available, fault tolerant web application for your current employer. The security team is concerned about an increase in malicious web-based attacks across the internet and asked what you can do to add a higher level of security to the website. How should you architect the solution on Oracle Cloud Infrastructure (OCI) to meet all requirements defined by your organization? (Choose the best answer.)

A. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Deploy a Web Application Firewall (WAF) and configure the load balancer public IP address as the origin.

B. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Create a Geolocation steering policy in Traffic Management and add an answer pool that directs to the public IP address of the load balancer. Configure a global catch-all rule to use this answer pool.

C. Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Ensure that each web application server is assigned a public IP address. Deploy a Web Application Firewall (WAF) and configure one Origin for each public IP address.

D. Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Use the OCI Traffic Management service to create a load balancing policy that will resolve DNS evenly between all web servers.
