Question 1

A data analytics company has been building Its now generation big data and analytics platform on OracleCloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their bigdata applications require such as high throughput to compute nodes with low latency file operations inaddition, their data needs to be stored redundantly across multiple nodes In a single availability domain andallows concurrent connections from multiple compute Instances hosted on multiple availability domains.Which OCI storage service can you use to meet i his requirement?

Options :

A : Object Storage

B : File System Storage

C : Archive storage

D : Block Volume

Answer: B

Question 2

You have an application running in Microsoft Azure and want to use Oracle Autonomous Data warehouse(ADW) instance for running business analytics.How can you build a secure solution for such a use-case?

Options :

A : Connect the Oracle ADW in your VCN to the Microsoft Azure VNet over the internet.

B : Create a software VPN connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance

C : Setup an interconnect between OCI and Microsoft Azure using FastConnect and ExpressRoute. Use a Service Gateway in OCI Virtual Cloud Network to provide connectivity to the Oracle ADW instance for the application in Microsoft Azure VNet.

D : Create a software Remote Peering Connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.

Answer: C

Question 3

You are working as a cloudconsultant for a major media company. In the US and your client requested to consolidate all of their log streams, access logs, application logs, and security logs into a single system. The client wants to analyze all of their logs In real-time based on heuristics and the result should be validated as well. This validation process requires going back to data samples extracted from the last 8 hours. What approach should you take for this scenario?

Options :

A : Create an auto scaling pool of syslog-enabled servers using compute instances which will store the logs In Object storage, then use map reduce jobs to extract logs from Object storage, and apply heuristics on the logs

B : Create a bare-metal instance big enough to host a syslog enabled server to process the logs and store logs on the locally attached NVMe SSDs for rapid retrieval of logs when needed.

C : Set up an OCI Audit service and ingest all the API arils from Audit service pragmatically to a client side application to apply heuristics and save the result inan OCI Object storage.

D : Stream all the logs and cloud events of Events service to Oracle Streaming Service. Build a client process that will apply heuristics on the logs and store them in an Object Storage

Answer: D

Question 4

You have been asked to implement a bespoke financial application in Oracle Cloud Infrastructure using virtualmachine instances controlled by Autoscaling across multiple Availability Domains. The application storestransaction logs, intermediate transaction data, and audit data and needs to store this on a persistent, durabledata store accessible from all of the application servers. The application requires the file system to be mountedin the /audit folder on theLinux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintaindata integrity. The solution should be as low maintenance as possible.What storage architecture should you suggest?

Options :

A : Use locally attached NVMe instances andconfigure RAID 0 replication between servers.

B : Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances.

C : Store the data on Oracle Object Storage mounted at the/audit mount point on all the Linux instances using the default mount options.

D : Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.

Answer: D

Question 5

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