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?

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 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?

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 3

A cloud consultant is working onimplementation project on OCI. As part of the compliance requirements, the

objects placed in object storage should be automatically archived first and then deleted. He is testing a

Lifecycle Policy on Object Storage and created a policy as below:

[ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes": "doc"] },

"timeAmount": 5, "timeunit": "DAYS", "isEnabled": true },

{ "name": "Delete_doc", "action": "DELETE", "objectNameFilter": "inclusionPrefixes": [ "doc"]

1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }

What will happen after this policy is applied?

A : All objects with names starting with "doc" will be deleted after 5 days of object creation

B : All the objects having file extension ".doc" will be archivedfor 5 days and will be deleted 10 days after object creation

C : All the objects having file extension ".doc" will be archived 5 days after object creation

D : All the objects with names starting with "doc" will be archived 5 days after object creation andwill be deleted 5 days after archival

Answer: A

Question 4

A retail company has recently adopted a hybrid architecture. They have the following requirements for their

end-to-end Connectivity model between their on-premises data center and Oracle Cloud Infrastructure (OC1)

region

*Highly available connection with service level redundancy

* Dedicated network bandwidth with low latency

Which connectivity setup is the most cost effective solution for this scenario?

A : Setup IPsec VPN as your primary connection, and a FastConnect virtual circuit as a backup connection. Use separate edge devices in your on-premises data canter for each connection from your edge devices, advertise more specific routes IPSec VPN, and specific routes through the backup FastConnect virtual circuit

B : SetupFastConnect virtual circuit as your primary connection, and a second FastConnect virtual circuit as a backup connection. Use separate edge devices in your FastConnect physical connectivity is redundant Use a single edge device in your on premises datacenter for each connection From yc device, advertise more specific routes via primary FastConnect virtual circuit, and less specific routes through t backup FastConnect circuit

C : Setup FastConnect virtual circuit as your primary connection, and an IPSecVPN as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes through FastConnect virtual circuit, and more specific routes through the backup IPSec VPN path.

D : Setup IPSec VPN as your primary connection, and a second IPSec VPN as a backup connection. Use separate edge devices in your on p data center for each connection. From your edge devices, advertise more specific routes via primary IPSec VPN. and lessspecific rod the backup IPSec VPN.

Answer: D

Question 5

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?

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
