Question 1

You have to migrate your application to Oracle Cloud Infrastructure (OCI). The database is constantly being updated and needs to be online without interruptions. How can you transition the database to OCI without interrupting its use?

Options :

A : It isimpossible to migrate without interruption.

B : Use an on-premises database with two-way synchronization to a cloud-based database and allow clients to connect to either databases.

C : Use an on-premises database with one-way synchronization to a cloud-baseddatabase and allow clients to connect only to the cloud database.

D : Use an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the on-premises database until it is synchronized.

Answer: D

Question 2

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 3

A civil engineering company is running an online portal In which engineers can upload there constructionsphotos, videos, and other digital files.There is a new requirement for you to implement: the online portal must offload the digital content to anObject Storage bucket for a period of 72 hours. After the provided time limit has elapsed, the portal will holdall the digital content locally and wait for the next offload period.Which option fulfills this requirement?

Options :

A : Create a pre-authenticated URL for the entire Object Storage bucket to read and list the content with an expiration of 72 hours

B : Create a pre authenticated URL lot each object that Is uploaded to the Object Storage bucket with an expiration of 72 hours

C : Create a Dynamic Group with matchingrule for the portal compute Instance and grant access to the Object Storage bucket for 72 hours.

D : Create a pre authenticated URL for the entire Object Storage bucket to write content with an expiration of 72 hours.

Answer: D

Question 4

Your company has recently deployed a new web application that uses Oracle functions Your managerInstructed you to Implement major manage your systems more effectively. You know that Oracle functionsautomatically 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 5

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
