Question 1

You are building a highly available and fault tolerant web application deployment for your company. Similar

applicationdelayed 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?

Options :

A : Configure auto scaling policy and it to WAF instance.

B : Configure Control Rules to send traffic to multiple web servers

C : Configure multiple origin servers

D : Configure new rules based on now vulnerabilities and mitigations

Answer: C

Question 2

A digital marketing company is planning to host awebsite on Oracle Cloud Infrastructure (OCI) and leverage

OCI Container Engine for Kubernetes (OKE). The web server will make API calls to access OCI Object

Storage to store all images uploaded by users.

For security purposes, your manager instructed youto ensure that the credentials used by the web server to

allow access not stored locally on the compute instance.

What solution results in an Implementation with the least effort for this scenario?

Options :

A : Configure the credentials using Instance Principal toallow the web server to make API calls to OCl Object Storage

B : Configure the credentials using OCI Registry (OC1R) which will automatically connect with OKE allowing the web server to make API calls to OCI Object Storage

C : Configure the credentials to use Transparent Data Encryption (TDE) which will automatically allow the web server to make API calls to OCl Object Storage

D : Configure the credentials using OCI Key Management to allow an instance to make API calls and grant access to OCl Object Storage.

Answer: A

Question 3

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?

Options :

A : Route 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 : Create 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 : Whitelist the Internet Gateway Public IP on the third party service and route all payment requests through the InternetGateway

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

Answer: A

Question 4

You have been asked to create a mobile application which will be used for submitting orders by users of a

popular E-Commerce site. The application is built to work with Autonomous Transaction Processing -

Serverless (ATP-S) databaseas the backend and HTML5 on Oracle Application Express as the front end.

During the peak usage of the application you notice that the application response time is very slow. ATP-S

database is deployed with 3 CPU cores and 1 TB of memory.

Which two optionsare expensive or impractical ways to improve the application response times?

Options :

A : Identify the maximum memory capacity needed for peak times and scale the memory for the ATP-S database to that number. ATP-S will scale the memory down when not needed.

B : Usethe Machine Learning (ML) feature of the ATP-S database iteratively to tune the SQL queries used by the application

C : Scale up CPU core count and memory during peak times.

D : Enable auto scaling for CPU cores on ATP-S database.

E : Identify the maximum CPU capacity needed for peak times and scale the CPU core count for the ATP-S database to that number. ATP-S will scale the CPU core count down when not needed.

Answer: A,C

Question 5

A large financialcompany 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 divertonly 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?

Options :

A : Use OCI Traffic management with failover steering policy and distribute the trafficbetween OC1 and on premises infrastructure.

B : Use OCI Traffic management 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
