Question 46

A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They have decided to use both containers and servers technologies to run these application instances.
Which option should you recommend to build this new platform?

A.Install a kubernetes cluster on OCI and use OCI event service.

B.Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.

C.Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.

D.Use OCI functions, OCI object storage and OCI event service.

Question 47

Your Oracle database is deployed on-premises and has produced 100 TB database backup locally. You have a disaster recovery plan that requires you to create redundant database backups in Oracle Cloud Infrastructure (OCI). Once the initial backup is completed, the backup must be available for retrieval in less than 30 minutes to support the Recovery Time Objective (RTO) of your solution.
Which is the most cost effective option to meet these requirements?

A.Use OCI Storage Gateway to transfer the backup files to OCI Object Storage Archive tier as the final destination.

B.Setup a FastConnect connection between on-premises data center and OCI. Then to use OCI CLI command to upload database backups to OCI Object Storage Standard tier as the final destination.

C.Use OCI Storage Gateway to transfer the backup files to OCI Object Storage Standard tier as the final destination.

D.Setup an IPsec VPNConnect between on-premises data center and OCI. Then to use OCI CLI command to upload database backups to OCI Object Storage Archive tier as the final destination.

Question 48

A new international hacktivist group, based in London, launched wide scale cyber attacks including SQL Injection and Cross-Site Scripting (XSS) across multiple websites which are hosted in Oracle Cloud Infrastructure (OCI). As an IT consultant, you must configure a Web Application Firewall (WAF) to protect these websites against the attacks.
How should you configure your WAF to protect the website against those attacks? (Choose the best answer.)

A.Enable an Access Rule that contains XSS Filters Categories and SQL Filters Categories.

B.Enable a Protection Rule to block the attacks based on HTTP Headers that contain XSS and SQL strings.

C.Enable a Protection Rule that contains XSS Filters Categories and SQL Filters Categories.

D.Enable an Access Rule to block the IP Address range from London.

E.Enable a Protection Rule to block requests that came from London.

Question 49

You are working as a cloud engineer for an IoT startup company which is developing a health monitoring pet collar for dogs and cats. The company collects biometric Information of the pet every second and then sends it to Oracle Cloud Infrastructure (OCI) Your task is to come up with an architecture which will accept and process the monitoring data as well as provide complete trends and health reports to the pet owners. The portal should be highly available, durable, and scalable with an additional feature for showing real time biometric data analytics.
which architecture will help you meet this requirement?

A.Create an OCI Object Storage bucket to collect the incoming biometric data from the smart pet collar Fetch the data horn OC\ Object storage to OCI Autonomous Data Warehouse (ADW) every day and run analytics Jobs with it

B.Use OCI Streaming Service to collect the incoming biometric data. Use an open source Hadoop cluster to analyze the data horn streaming service. Store the results to OCI Autonomous Data warehouse (ADW) to handle complex analytics.

C.Launch an open source Hadoop cluster to collect the Incoming biometrics data Use an Open source Fluentd cluster to analyze the- data me results to OCI Autonomous Transaction Processing (ADW)to handle complex analytics

D.Use OCI Streaming Service to collect the incoming biometric data. Use Oracle Functions to process the date and show the results on a real-time dashboard and store the results lo OCI Object Storage Store the data In OCI Autonomous Data warehouse (ADW) to handle analytics.

Question 50

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) database as 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 options are expensive or impractical ways to improve the application response times?

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.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.

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

D.Use the Machine Learning (ML) feature of the ATP-S database iteratively to tune the SQL queries used by the application.

E.Scale up CPU core count and memory during peak times.
