Question No. 1

You are a solutions architect for a global health care company which has numerous data centers around the globe. Due to the ever growing data that your company is storing, you were Instructed to set up a durable, cost effective solution to archive you data from your existing on-premises tape based backup Infrastructure to Oracle Cloud Infrastructure (OCI).

What is the most-effective mechanism to Implement this requirement?

AUse the File Storage Service in OCI and copy the data from your existing tape based backup to the shared file system

BSetup an on premises OCI Storage Gateway which will back up your data to OCI Object Storage Archive tier.(Correct)

CSetup an on premises OCI Storage Gateway which will back up your data to OCI object Storage Standard tier. Use Object Storage life cycle policy management to move any data older than 30 days from Standard to Archive tier.

DSetup an on-promises OCI Storage Gateway which will back up your data to OCI Object Storage Standard

ESetup fastConnect to connect your on premises network to your OCI VCN and use rsync tool to copy your data to OCI Object Storage Archive tier.

Show Answer

Correct Answer: B

Oracle Cloud Infrastructure offers two distinct storage tiers for you to store your unstructured data. Use the Object Storage Standard tier for data to which you need fast, immediate, and frequent access. Use the Archive Storage service's Archive tier for data that you access infrequently, but which must be preserved for long periods of time. Both storage tiers use the same manageable resources (for example, objects and buckets). The difference is that when you upload a file to Archive Storage, the object is immediately archived. Before you can access an archived object, you must first restore the object to the Standard tier.

you can use Storage Gateway to move files to Oracle Cloud Infrastructure Archive Storage as a cost effective backup solution. You can move individual files and compressed or uncompressed ZIP or TAR

archives. Storing secondary copies of data is an ideal use case for Storage Gateway.

Question No. 2

You are helping a customer troubleshoot a problem. The customer has several Oracle Linux servers in a private subnet within a Virtual Cloud Network (VCN). The servers are configured to periodically communicate to the Internet to get security patches for applications Installed on them.

The servers are unable to reach the Internet. An Internet Gateway has been deployed In the public subnet in the VCN and the appropriate routes are configured in the Route Table associated with the public subnet.

Based on cost considerations, which option will fix this Issue?

ACreate a Public Load Balancer In front of the servers and add the servers to the Backend Set of the Public Load Balancer.

BCreate another Internet Gateway and configure it as route target for the private subnet.

CImplement a NAT instance In the public subnet of the VCN and configure the NAT instance as the route target for the private subnet.

DCreate a NAT gateway in the VCN and configure the NAT gateway as the route target for the private subnet.

Correct Answer: A

Question No. 3

A fast growing E-commerce company has deployed their online shopping application on Oracle Cloud Infrastructure. The application was deployed on compute instances with Autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend. In order to promote their e-commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints.

What could be two possible reasons for this situation?

AThe health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation.

BAs part of Autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change.

CThe health check on some of the backend servers has failed and the load balancer was rebooting these servers.

DAutoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.

Correct Answer: A, D

Question No. 4

An E-commerce company which sells computers, tablets, and other electronics items has recently decided to move all of their on-premises infrastructure to 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.

They cannot afford to have any application down time when they do the migration.

What is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?

ALaunch a compute instance and run an 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 Oracle Data Pump and then enable automatic backups.

BLaunch 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.

CLaunch 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.

DLaunch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Setup Oracle GoldenGate to synchronize data from their on-premises database to OCIVM Database. Export and Import the on-premises database to OCIVM DB Systems using Oracle Data Pump, apply the GoldenGate trail files to sync up the OCI database with the on-premises database. Enable automatic backups for the OCIVM database and then cutoverthe application from on-premises to OCI.

Question No. 5

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?

ASetup 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.

BSetup FastConnect 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 data center for each connection From yc device, advertise more specific routes via primary FastConnect virtual circuit, and less specific routes through t backup FastConnect circuit.

CSetup FastConnect virtual circuit as your primary connection, and an IPSec VPN 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.

DSetup 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 less specific rod the backup IPSec VPN.
