Question 1

A global media organization is working on a project which letsusers upload their videos on their site. After upload is complete, the video should be automatically processed by an Al algorithm. The algorithm will try to recognize actions in the videos so that it can be used to show related advertisements in future. The development team wants to focus on writing Al code and don't want to worry about underlying infrastructure for high-availability, scalability, security and monitoring. Which OCI services should you recommend for this project?

Options :

A : Use OCI Events servicefor triggering automatic processing of video, Oracle Container Engine for Kubernetes (OKE) and OCI Digital Assistant

B : Use Oracle Container Engine for Kubernetes (OKE) for deployment of Al Code, OCI Notifications and Object Storage

C : Use OCI Resource Manager to manage the underlying infrastructure, OCI Functions and OCI Events service

D : Use Object Storage for storing videos, OCI Events service and OCI Functions

Answer: D

Question 2

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?

Options :

A : It isimpossible to migrate without interruption.

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

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

D : Use 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 3

A developer is using Oracle Functions to deploy her code as part of an event-driven solution in Oracle Cloud Infrastructure (OCI). When sheinvokes her function, Oracle Functions returns a FunctionlnvokelmageNotAvailable message and a 502 error

Which of the following options is NOT a plausible reason for this error?

Options :

A : Missing or invalid IAM policy to give Oracle Functions read access to images stored for functions in repositories in OCI Registry.

B : The function does not exist in the specified location in OCI Registry.

C : The VCN being used does not have an internet gateway or a service gateway configured for Oracle Functions to be able toaccess OCI Registry.

D : OCI Events service rule is not configured with the correct location of the function in OCI Registry.

Answer: D

Question 4

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 5

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.
