Question 1

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 2

You are working as a solution architect for an online retail store to create a portal to allow the users to pay fortheir groceries using credit cards. Since the application is not fully compliantwith the Payment Card IndustryData Security Standard (PCI DSS), your company is looking to use a third party payment service to processcredit card payments.The third party service allows a maximum of Spelunk IP addresses 5 public IP addresses at a timeHowever,your website is using Oracle Cloud Infrastructure (OCI) Instance Pool Auto Scaling policy to create up tocreate up to 15 Instances during peak traffic demand, which are launched In VCN private in VCN privatesubnets and attached to an OCI public Load Balancer. Upon user payment, the portal connects to the paymentservice over the Interne! to complete the transactionWhat solution can you implement to make sure that all compute Instances can connect to the third partysystem to process the payments aw peak traffic demand?

Options :

A : Route credit card payment request from the compute instances through the NAT Gateway. On the third-party services, whitelist the public IP associated with the NAT Gateway

B : Create an OCI Command Line Interface (CLI) scriptto automatically reserve public IP address for the compute instances. On the third-party services, whitelist the Reserved public IP

C : Whitelist the Internet Gateway Public IP on the third party service and route all payment requests through the InternetGateway

D : Route payment request from the compute instances through the OCI Load Balancer, which will then be routed to the third party service

Answer: A

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

A hospital in Austin has hosted its web based medical records portal entirely In Oraclecloud Infrastructure(OCI) using Compute Instances for its web-tier and DB system database for its data tier. To validatecompliance with Health Insurance Portability and Accountability (HIPAA), the security professional to checktheir systems it was found that there are a lot of unauthorized coming requests coming from a set of IPaddresses originating from a country in Southeast Asia.Which option can mitigate this type of attack?

Options :

A : Block the attacking IP address by implementing a OCI Web Application Firewall policy using Access Control Rules

B : Block the attacking IP address by implementing a OCI Web Application Firewall policy using AccessControl Rules

C : Mitigate the attack by changing the Route fable to redirect the unauthorized traffic to a dummy Compute instance

D : Block the attacking IP address by creating a Security List rule to deny access to the subnet where the web server Is running

Answer: B

Question 5

You have been asked to create a mobile application which will be used for submitting orders by users of apopular 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-Sdatabase 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.
