Question #41

A global media organization is working on a project which lets users upload their videos on their site. After upload is complete, the video should be automatically processed by an Al algorithm. The algorithm will try to recognize actions in the videos so that it can be used to show related advertisements in future. The development team wants to focus on writing Al code and don't want to worry about underlying infrastructure for high-availability, scalability, security and monitoring.
Which OCI services should you recommend for this project?

A. Use OCI Events service for triggering automatic processing of video, Oracle Container Engine for Kubernetes (OKE) and OCI Digital Assistant

B. Use Object Storage for storing videos, OCI Events service and OCI Functions

C. Use OCI Resource Manager to manage the underlying infrastructure, OCI Functions and OCI Events service.

D. Use Oracle Container Engine for Kubernetes (OKE) for deployment of Al Code, OCI Notifications and Object Storage

Question #42

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

A. Mitigate the attack by changing the Route fable to redirect the unauthorized traffic to a dummy Compute instance

B. Block the attacking IP address by creating by Network Security Group rule to deny access to the compute Instance where the web server Is running

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

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

Question #43

A retail company runs their online shopping platform entirely on Oracle cloud Infrastructure (OCI). This is a 3-tier web application that Includes a Mbps Load Balancer. Virtual Machine Instances for web and an Oracle DB Systems Virtual Machine Due to unprecedented growth, they noticed an Increase in the Incoming traffic to their website and all users start getting 503 (Service Unavailable) errors.
What is the potential problem in this scenario?

A. The Traffic Management Policy is not set to load Balancer the traffic to the web servers.

B. All the web servers are too busy and not able to answer any request from users.

C. The Database Is down hence users can not access the web site

D. You did not configure a Service Gateway to allow connection between web servers and load Balance

E. The Load Balancer health check status Indicates critical situation for half of the backend webservers

Which of the following options will minimize this problem?

A. Reduce the TTL of the DNS records after the switch.

B. Increase the TTL of the DNS records before the switch.

C. Increase the TTL of the DNS records after the switch.

D. Reduce the TTL of the DNS records before the switch.

E. DNS changes propagate fast enough that it is not necessary to take any action.

Question #45

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 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.

B. 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.

C. 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.

D. 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.

Question #46

The Finance department of your company has reached out to you. They have customer sensitive data on compute Instances In Oracle Cloud Infrastructure (OCI) which they want to store in OCI Storage for long term retention and archival.
To meet security requirements they want to ensure this data is NOT transferred over public internet, even if encrypted.
which they want to store In OCI Object Storage fin long term retention and archival To meet security requirements they want to ensure this data is NOT transferred over public Internet, even it encrypted.
Which option meets this requirements?

A. Use NAT gateway with appropriate route table when transferring data. Then use NAT gateways' toggle (on/off) once data transfer is complete.

B. Use Service gateway with appropriate route table.

C. Configure a NAT instance and all traffic between compute In Private subnet should use this NAT instance with Private IP as the route target.

D. Use Storage gateway with appropriate firewall rule.

Question #47

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?

A. Launch 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.

B. Launch 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.

C. Launch 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.

D. Launch 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.

Question #48

Given this compartment structure:

You are managing a compute instance that currently resides in the Compute compartment. The Virtual Cloud Network (VCN) into which the compute instance was originally deployed, also resides in this compartment. To support a project-related task, you need to move just the compute instance to the SysTest-Team compartment. You log into your Oracle Cloud Infrastructure (OCI) account and use the Move Resource option to place the compute instance in the new compartment.
What will be the result of your attempt to move the compute instance to the new compartment? (Choose the best answer.)

A. After moving the compute instance, you must move the compute instance VNIC as a separate action. The public and private IP addresses of the instance will remain unchanged and it will still be associated with the VCN from the source compartment.

B. The move will be successful. However, the compute instance's public and private IP addresses will change, and it will be associated to the first VCN that was created in the new, target compartment.

C. The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the compute instance can be moved.

D. The move will be successful. The compute instance's public and private IP addresses will stay the same. The compute instance will remain associated with the VCN from the source compartment.
