You are working as a cloud engineer for an IoT startup company which is developing a health monitoring pet collar for dogs and cats. The company collects biometric Information of the pet every second and then sends it to Oracle Cloud Infrastructure (OCI) Your task is to come up with an architecture which will accept and process the monitoring data as well as provide complete trends and health reports to the pet owners. The portal should be highly available, durable, and scalable with an additional feature for showing real time biometric data analytics.

Which architecture will help you meet this requirement?

A. Use OCI Streaming Service to collect the incoming biometric data. Use Oracle Functions to process the date and show the results on a real-time dashboard and store the results lo OCI Object Storage Store the data In OCI Autonomous Data warehouse (ADW) to handle analytics.

B. Launch an open source Hadoop cluster to collect the Incoming biometrics data Use an Open source Fluentd cluster to analyze the- data me results to OCI Autonomous Transaction Processing (ADW)to handle complex analytics

C. Create an OCI Object Storage bucket to collect the incoming biometric data from the smart pet collar Fetch the data horn OC\ Object storage to OCI Autonomous Data Warehouse (ADW) every day and run analytics Jobs with it

D. Use OCI Streaming Service to collect the incoming biometric data. Use an open source Hadoop cluster to analyze the data horn streaming service. Store the results to OCI Autonomous Data warehouse (ADW) to handle complex analytics.

You are tasked with building a highly available, fault tolerant web application for your current employer. The security team is concerned about an increase in malicious web- based attacks across the internet and asked what you can do to add a higher level of security to the website.

How should you architect the solution on Oracle Cloud Infrastructure (OCI) to meet all requirements defined by your organization? (Choose the best answer.)

A. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Deploy a Web Application Firewall (WAF) and configure the load balancer public IP address as the origin.

B. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Create a Geolocation steering policy in Traffic Management and add an answer pool that directs to the public IP address of the load balancer. Configure a global catch-all rule to use this answer pool.

C. Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Ensure that each web application server is assigned a public IP address. Deploy a Web Application Firewall (WAF) and configure one Origin for each public IP address.

D. Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Use the OCI Traffic Management service to create a load balancing policy that will resolve DNS evenly between all web servers.

A digital marketing company is planning to host a website on Oracle Cloud Infrastructure (OCI) and leverage OCI Container Engine for Kubernetes (OKE). These web servers will make API calls to access OCI Object Storage to store all images uploaded by users.

For security purposes, you must ensure that the credentials used by the web server to allow access to OCI Object Storage are not stored in the compute instance.

What solution results in an implementation with the least-effort for this scenario?

A. Configure the credentials to use Transparent Data Encryption (TDE) to automatically allow the web server to make API calls to the OCI Object Storage.

B. Configure the credentials using OCI Registry (OCIR) to automatically connect with OKE allowing the web server to make API calls to the OCI Object Storage.

C. Configure the credentials using OCI Vault to allow an instance to make API calls and grant access to OCI Object Storage.

D. Configure the credentials using Instance Principals to allow the web server to make API calls to the OCI Object Storage.

You are building a highly available and fault tolerant web application deployment for your company. Similar application delayed by competitors experienced web site attack including DDoS which resulted in web server failing.

You have decided to use Oracle Web Application Firewall (WAF) to implement an architecture which will provide protection against such attacks and ensure additional configuration will you need to implement to make sure WAF is protecting my web application 24?.

Which additional configuration will you need to Implement to make sure WAF Is protecting my web application 24??

A. Configure auto scaling policy and it to WAF instance.

B. Configure Control Rules to send traffic to multiple web servers

C. Configure multiple origin servers

D. Configure new rules based on now vulnerabilities and mitigations

There are two compartments: Networks and Devlnstances There are two groups: NetworkAdmins with a user named Nick, and Devs with a user named Dave The following IAM policies are being used: *Allow group NetworkAdmins to manage virtual-network-family in compartment Networks *Allow group NetworkAdmins to manage instance-family in compartment Networks *Allow group Devs to use virtual-network-family in compartment Networks *Allow group Devs to manage all-resources in compartment Devlnstances Nick creates a VCN in Networks compartment. Dave creates a VCN in Devlnstances compartment. Which of the following statements is INCORRECT?

A. Dave launches instances in Devlnstances using the VCN in Networks compartment

B. Nick cannot launch new instances in Devlnstances compartment

C. Nick launches instances in Networks using VCN in Devlnstances compartment

D. Dave cannot launch new instances in Networks compartment

Your company has recently deployed a new web application that uses Oracle functions Your manager Instructed you to Implement major manage your systems more effectively. You know that Oracle functions automatically monitors functions on your behalf reports metrics through Service Metrics.

Which two metrics are collected and made available by this feature?

A. length of time a function runs

B. number of times a function is removed

C. number of times a function is invoked

D. amount of CPU used by a function

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?

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

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

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

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

You are trying to troubleshoot the configuration of your Oracle Cloud Infrastructure (OCI) Load Balancing service. You have a backend HTTP service for which you have created a backend set in the load balancer. You have configured health checks for the backend set. Although the health checks appear good, customers sometimes experience transaction failures.

Which of the following options will definitely lead to this problem?

A. You are NOT using regional subnets in your Virtual Cloud Network. With Availability Domain (AD) specific subnet. the compute instances of the backend service running in the subnet have issues when the AD is down.

B. You are using OCI Domain Name System. You have misconfigured the 'A' record with the wrong IP address leading to requests not getting routed correctly.

C. You are using iSCI for block volume attachment to the compute instances in your backed HTTP service. TCP/IP configuration of your block volume attachment is not configured correctly, leading to issues in your backend service.

D. You are running a TCP-level health check against your HTTP service. The TCP handshake can succeed and indicate that the service is up even when the HTTP service has issues.
