Question 1

You are responsible formigrating your on premises legacy databases on 11.2.0.4 version to Autonomous Transaction Processing Dedicated (ATP-D) In Oracle Cloud Infrastructure (OCI). As a solution architect, you need to plan your migration approach. Which two options do you needto implement together to migrate your on premises databases to OCI?

Options :

A : Use Oracle Data Guard to keep on premises database always active during migration

B : Retain changes to Oracle shipped privileges, stored procedures or views In the on-premises databases.

C : Use Oracle GoldenGate replication to keep on premises database online during migration.

D : Convert on-premises databases to PDB, upgrade to 19c, and encrypt Migration.

E : Retain all legacy structures and unsupported features (e.g. taw U>Bs) In the onuses databases for migration.

Answer: C,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?

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 3

Your company has recently deployed a new web application that uses Oracle functions Your manager

Instructed you to Implement major manage your systems more effectively. You know that Oracle functions

automatically monitors functions on your behalf reports metrics through Service Metrics.

Which two metrics are collected and made available by this feature?

Options :

A : length of time a function runs

B : number of times a function is removed

C : number of times a function isinvoked

D : amount of CPU used by a function

E : number of concurrent connections

Answer: A,C

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?

Options :

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 working as a security consultant with a global insurance organization which is using Microsoft Azure Active Directory as an identity provider to manage user login/passwords. When a user logs in to Oracle Cloud Infrastructure (OCI) console, it should get authenticated by Azure AD. Whichset of steps are required to be configured in OCI to meet this requirement?

Options :

A : Setup Azure AD as an Identity Provider, import users and groups from Azure AD to OCI, set up IAM policies to govern access to Azure AD groups.

B : Setup Azure AD as an Enterprise Application, configure OCI for single sign-on, map Azure AD groups to OCI groups, set up the IAM policies to govern access to Azure AD groups

C : Setup Azure AD as an Enterprise Application, map Azure AD users, groups and policies to OCI groups and users

D : Setup Azure AD as an Identity Provider, map Azure AD groups to OCI groups, set up the IAM policies to govern access to Azure AD groups
