Question 2

A cost conscious fashions design company which sells bags, clothes, and other luxury items has recently decided to more all of the their on-premises infrastructure Oracle Cloud Infrastructure (OCI), One of their on-premises application is running on an NGINX server and the Oracle Database is running in a 2 node Oracle Real Application Clusters (RAC) configuration.
Based on cost considerations, what is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?

A. Launch a compute Instance for both the NGINX application server and the database server. Attach block volumes on the database server compute instance and enable backup policy to backup the block volumes.

C. Launch a compute Instance and run an NGINX server to host the application. Deploy Exadata Quarter Rack, enable automatic backups and import the database using Oracle Data Pump.

D. Launch a Compute instance and run a NGINX Server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled Import the on premises database to OCI VM DB Systems using data pump and then enable automatic backup- Also, enable Oracle Data Guard on the database server

Question 3

Your customer has gone through a recent departmental re structure. As part of this change, they are organizing their Oracle Cloud Infrastructure (OCI) compartment structure to align with the company's new organizational structure.
They have made the following change:
Compartment x Is moved, and its parent compartment is now compartment c.

Policy defined in compartment A: Allow group networkadmins to manage subnets in compartment X Policy defined in root compartment: Allow group admins to read subnets in compartment Finance:A:X After you move the compartment, which two IAM policies would be required to ensure both groups retain the same permissions to compartment X that they had before? (Choose two.)

A. Define a policy in compartment C as follows: Allow group networkadmins to read subnets in compartment X

B. Define a policy in compartment HR as follows: Allow group networkadmins to manage subnets in compartment C:X.

C. Define a policy in the root compartment as follows: Allow group admins to manage subnets in compartment Finance:A:X

D. Define a policy in the root compartment as follows: Allow group admins to read subnets in compartment HR:C:X

Correct Answer: B,D

Question 4

You are designing the network infrastructure for two application servers: appserver-1 and appserver-2 running in two different subnets inside the same Virtual Cloud Network (VCN) Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access appserver-1 from the internet and appserver-2 from the on-premises network. The on-premises network is connected to your VCN over a FastConnect virtual circuit.
How should you design your routing configuration to meet these requirements?

A. Configure two routing table (Route table-1 Route Table-2) that have rule to route all traffic via the Dynamic Routing Gateway (DRG) Associate the two routing tables with all the VCN subnets.

B. Configure two routing tables: Route Table-1 that has a route to internet via the Internet gateway. Associate this route table to the subnet containing appserver-1. Route Table-2 that propagate specific routes for the on-premises network via the Dynamic Routing Gateway (DRG) Associate this route table to subnet containing appserver-2.

C. Configure a single routing table (Route Table-1) that has two set of rules. One that has route to internet via the internet Gateway and another that propagate specific routes for the on-premise network via the Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.

D. Configure a single routing table (Routing Table-1) that has two set of rules: one that has route to internet via the Internet Gateway and another that propagates specific routes for the on-premises network via Dynamic Routing Gateway (DRG). Associate the routing table with the VCN.

Correct Answer: B

Question 5

You are creating an Oracle Cloud Infrastructure Dynamic Group. To determine the members of this group you are defining a set of matching rules.
Which of the following are the supported variables to define conditions in the matching rules? (Choose Two)

A. instance.compartment.id - the OCID of the compartment where the instance resides.

B. instance.tenancy.id - the OCID of the tenancy where the instance resides.

C. tag.<tagnamespace>.<tagkey>.value - the tag namespace and tag key.

D. iam.policy.id - the OCID of the IAM policy to apply to the group.

Correct Answer: A,C

Question 6

Your company needs to migrate a business critical application from your data center to Oracle Cloud Infrastructure (OCI). The application runs on Oracle Database and both the application and database servers run on Oracle Linux version 7. The application server is WebLogic server running on multiple 4-core servers and the database is deployed as an Oracle Database Enterprise Edition RAC database on 2 servers (4-cores each).
Which method of database migration should you choose so that the application has minimal impact? (Choose the best answer.)

A. Deploy Virtual Machine RAC DB system on OCI and use the Oracle Database Backup module with RMAN to migrate the data from customer on-premises to OCI.

B. Deploy Autonomous Transaction Processing Database on OCI and use the MV2ADB tool for the database migration.

C. Deploy Exadata Cloud Service Base rack and use Oracle Data Pump tool to migrate the data from customer on-premises to OCI.

D. Deploy Virtual Machine RAC DB system on OCI and use the ZDM tool for the database migration.

Question 7

You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use 'Volume Groups' feature. The Block volume and Compute instances exist in different compartments within your tenancy.
Periodically, a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.
What could be the cause?

A. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

B. You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.

C. You are exceeding your volume group backup quota configured.

D. A compute instance with multiple block volumes attached cannot move when a compartment is moved.

Correct Answer: A

Question 8

A startup company is looking for a solution for processing of data transmitted by the IOT devices fitted to transport vehicles that carry frozen foods. The data should be consumed and processed in real time. The processed data should be archived to OCI Object Storage bucket. and use Autonomous Data warehouse (ADW) to handle analytics.
Which architecture will help you meet this requirement?
