Question 1

You are tasked with building a highly available, fault tolerant web application for your current employer. Thesecurity team is concernedabout an increase in malicious web-based attacks across the internet and asked whatyou 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 definedbyyour organization? (Choose the best answer.)

Options :

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 theweb 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.

Answer: A

Question 2

You have an application running in Microsoft Azure and want to use Oracle Autonomous Data warehouse(ADW) instance for running business analytics.How can you build a secure solution for such a use-case?

Options :

A : Connect the Oracle ADW in your VCN to the Microsoft Azure VNet over the internet.

B : Create a software VPN connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance

C : Setup an interconnect between OCI and Microsoft Azure using FastConnect and ExpressRoute. Use a Service Gateway in OCI Virtual Cloud Network to provide connectivity to the Oracle ADW instance for the application in Microsoft Azure VNet.

D : Create a software Remote Peering Connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.

Answer: C

Question 3

You are responsible formigrating your on premises legacy databases on 11.2.0.4 version to Autonomous Transaction Processing Dedicated (ATP-D) In Oracle Cloud Infrastructure (OCI). As a solution architect, you need to plan your migration approach. Which two options do you needto implement together to migrate your on premises databases to OCI?

Options :

A : Use Oracle Data Guard to keep on premises database always active during migration

B : Retain changes to Oracle shipped privileges, stored procedures or views In the on-premises databases.

C : Use Oracle GoldenGate replication to keep on premises database online during migration.

D : Convert on-premises databases to PDB, upgrade to 19c, and encrypt Migration.

E : Retain all legacy structures and unsupported features (e.g. taw U>Bs) In the onuses databases for migration.

Answer: C,D

Question 4

You are responsible for migrating your on-premises legacy databases on 11.2.0.4 version to AutonomousTransaction Processing - Dedicated (ATP-D) in OracleCloud Infrastructure (OCI).

Options :

A : Retain all legacy structures and unsupported features (e.g. legacy LOBs) in the on-premises databases for migration

B : Use Oracle Data Guard to keep on-premises database always active during migration.

C : Launch Autonomous Transaction Processing - Dedicated database in OCI.

D : Retain changes to Oracle shipped privileges, stored procedures or views in the on-premises databases.

E : Convert on-premises databases to PDB, upgrade to 19c, and encrypt.

F : Use Oracle GoldenGate replication to keep on-premises database online during migration.

Answer: A,C

Question 5

A company runs a public-facing application that uses a Java-based web service via a RESTful API in their on-premises data center. Use of the API is expected to double with a new product launch. The business wants to migrate their application to Oracle Cloud Infrastructure (OCI) to meet the scale and reliability requirements. In order to achieve this, they will divert only 40% of the traffic to the new Apache Tomcat web servers running on OCI and serve the remaining 60% traffic through their on-premises infrastructure. Once the migration is complete and application works fine, they will divert all traffic to OCI. How can these requirements be met with the LEAST amount of effort?

Options :

A : Use OCI Traffic management service with failover steering policy and distribute the traffic between OCI and on premises infrastructure.

B : Use OCI Traffic management service with Load Balancing steering policy and distribute the traffic between OCI and on premises infrastructure

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

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