Question 1

You are working as a solution architect for an online retail store to create a portal to allow the users to pay for

their groceries using credit cards. Since the application is not fully compliantwith the Payment Card Industry

Data Security Standard (PCI DSS), your company is looking to use a third party payment service to process

credit card payments.

The third party service allows a maximum of Spelunk IP addresses 5 public IP addresses at a timeHowever,

your website is using Oracle Cloud Infrastructure (OCI) Instance Pool Auto Scaling policy to create up to

create up to 15 Instances during peak traffic demand, which are launched In VCN private in VCN private

subnets and attached to an OCI public Load Balancer. Upon user payment, the portal connects to the payment

service over the Interne! to complete the transaction

What solution can you implement to make sure that all compute Instances can connect to the third party

system to process the payments aw peak traffic demand?

A : ute credit card payment request from the compute instances through the NAT Gateway. On the third-party services, whitelist the public IP associated with the NAT Gateway

B : eate an OCI Command Line Interface (CLI) scriptto automatically reserve public IP address for the compute instances. On the third-party services, whitelist the Reserved public IP

C : itelist the Internet Gateway Public IP on the third party service and route all payment requests through the InternetGateway

D : ute payment request from the compute instances through the OCI Load Balancer, which will then be routed to the third party service

Answer: A

Question 2

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?

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

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

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

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

Answer: B

Question 3

You have designed and deployed your Autonomous Data Warehouse (ADW) such that it is accessible from

your on-premises data center and servers running on both private and public networks in Oracle Cloud

Infrastructure (OCI).

As you are testing the connectivity to your ADW database from the different access paths, you notice that the

server running on the private network isunable to connect to ADW.

Which two steps do you need to take to enable connectivity from the server on the private network to ADW?

(Choose two.)

A : an entry in the Security List of the ADW allowing ingress traffic for C10R block 10.2.2.0/24

B : dan entry in the route table (associated with the private subnet) with destination of 0.0.0.0/: target type of NAT Gateway, add a stateful egress rule to the security list (associated with the private subnet) with destination of 0.0.0.0./0 and for all IP protocols.

C : an entry in the access table list of ASW for CIDR block 10.2.2.0/24.

D : an entry in the route table (associated with the private subnet) with destination of 0.0.0.0./0; target type of internet Gateway, add a stateful egress in the security list (associated with the private subnet) with destination of 0.0.0.0/0 and for all IP protocols.

E : an entry in the access control list of ADW for IP address 129.146.160.11

Answer: A,B

Question 4

You have to migrate your application to Oracle Cloud Infrastructure (OCI). The database is constantly being updated and needs to be online without interruptions. How can you transition the database to OCI without interrupting its use?

A : isimpossible to migrate without interruption.

B : an on-premises database with two-way synchronization to a cloud-based database and allow clients to connect to either databases.

C : an on-premises database with one-way synchronization to a cloud-baseddatabase and allow clients to connect only to the cloud database.

D : an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the on-premises database until it is synchronized.

Answer: D

Question 5

Your company needs to migrate a business critical application from your data center to Oracle Cloud

Infrastructure (OCI). The application runs on Oracle

Database and both the application and database servers run on Oracle Linux version 7. The application server

is WebLogic server running on multiple 4-core servers and the database is deployed as an Oracle Database

Enterprise Edition RAC database on 2 servers (4-cores each).

Which method of database migration should you choose so that the application has minimal impact? (Choose

the best answer.)

A : ploy Virtual Machine RAC DB system on OCI and use the Oracle Database Backup module with RMAN to migrate the data from customer on-premises to OCI.

B : ploy Virtual Machine RAC DB system on OCI and use the ZDM tool for the database migration.

C : ploy Autonomous Transaction Processing Database on OCI and use the MV2ADB tool for thedatabase migration.

D : ploy Exadata Cloud Service Base rack and use Oracle Data Pump tool to migrate the data from customer on-premises to OCI.

Answer: B
