Question 1

You work for a bank as the lead Oracle Cloud Infrastructure architect. You designed a highly scalable solution for your company's banking application. The architecture includes a load balancer, application servers with autoscaling configuration based on CPU utilization, and an Autonomous Database with Transaction Processing workload type running in a Virtual Cloud Network (VCN).
During the peak utilization period, the application users complain that the application runs slow.
What are two possible reasons for the application running slow at times? (Choose two.)

A. The load balancer is not configured correctly to send traffic to all the listeners of the application servers in the backend set. B. The VCN does not have a Network Security Group configured to allow traffic from the load balancer to all the application servers in the backend set. C. Instance pool in autoscaling configuration for the Autonomous Database did not scale out due to misconfigured scaling policy. D. Instance pool in autoscaling configuration for the application servers did not scale out due to service limit breach of the VM shapes used by the application servers. E. Instance pool in autoscaling configuration for the application servers did not scale out due to compartment quota breach of the VM shapes used by the application servers.

Correct Answer: D,E

Question 2

An automobile company wants to deploy their CRM application for Oracle Database on Oracle Cloud Infrastructure (OC1) DB Systems for one of major clients. In compliance with the Business Continuity Program of the client, they need to provide a Recovery Point objective (RPO) of 24 hours and a Recovery time objective (RTO) of 24 hours and Recovery Time Objective (RTO) of 1 hour.
The CRM application should be available oven in me event that an entire on Region is down.
Which approach Is the most suitable and cost effective configuration for this scenario?

A. Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard. B. Deploy a 1 node VM Oracle database in one region. Manual Configure a Recovery Manager (RMAN) database backup schedule to take hourly database backups. Asynchronously copy the database backups to object storage in another OCI region, If the primary OCI region is unavailable launch a new 1 new VM Database in the other OCI region restore the production database from the backup. C. Deploy an Autonomous Transaction Processing (Serverless) database in one region and replicate it to an Autonomous Transaction Processing (Serverless) database in another region Oracle GoldenGate. D. Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.

Question 3

You have 10 Oracle Linux Compute instances within the ociarchpro compartment running in Oracle Cloud Infrastructure (OCI). The instances are placed in a private subnet inside a Virtual Cloud Network (VCN). You plan to leverage the Oracle Vulnerability Scanning service to gain visibility into potential vulnerabilities. Your goal is to improve the overall security posture.
You create a Scan recipe with the following settings:
Type: Compute -
Name: ociproscanrecipe -
CIS benchmark scanning: Enabled -
CIS benchmark profile: Medium (More than 40% of the benchmarks failing is a high risk) Schedule: Daily - You create a target with the following settings:
Type: Compute -
Compartment: ociarchpro -
Scan recipe: ociproscanrecipe -
Targets: All compute instances in the selected target compartment and its sub-compartments However, you are not able to see the result of host scans for the compute target.
For the given scenario, which is NOT a valid troubleshooting task?

A. Create a service gateway for the Virtual Cloud Network (VCN) and configure a route rule. B. Disable agent-based scanning in the recipe. C. Enable the scanning plugin on the Oracle Cloud Agent if you manually disabled it on the target compute instances. D. Check whether the target was created less than 24 hours ago.

Correct Answer: A

Question 4

An online registration system Is currently hosted on one large Oracle Cloud Infrastructure (OCT) Bare metal compute Instance with attached block volume to store of the users' dat a. The registration system accepts the Information from the user, Including documents and photos then performs automated verification and processing to check it the user is eligible for registration.
The registration system becomes unavailable at tunes when there is a surge of users using the system the existing architecture needs improvement as it takes a long time for the system to complete the processing and the attached block volumes are not large enough to use data being uploaded by the users.
Which Is the most effective option to achieve a highly scalable solution?

A. Upgrade your architecture to use more Block volumes as the data volume Increases. Replace the single bare metal instance with a group of compute instances with Auto Scaling to dynamically increase or decrease the compute instance pools depending on the traffic. B. Change your architecture to use an OCI Object Storage standard tier bucket, replace the single bare metal instance with a Oracle Streaming Service (OSS) to ingest the Incoming requests and distribute the tasks to a group of compute Instances with Auto Scaling C. Attach more Block volumes as the data volume increase, use Oracle Notification Service (ONS) to distribute tasks to a pool of compute instances working In parallel, and Auto Scaling to dynamically size the pool of Instances depending on the number of notifications received from the Notification Service. Use Resource Manager stacks to replicate your architecture to another region. D. Upgrade your architecture to use a pool of Bare metal servers and configure them to use their local SSDs for faster data access Set up Oracle Streaming Service (OSS) to distribute the tasks to the pool of Bare metal Instances with Auto Scaling to dynamically increase or decrease the pool of compute instances depending on the length of the Streaming queue.

Correct Answer: A

Question 5

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 Instance Principals to allow the web server to make API calls to the OCI Object Storage. D. Configure the credentials using OCI Vault to allow an instance to make API calls and grant access to OCI Object Storage.

Correct Answer: C

Question 6

A cost conscious fashions design company which sells bags, clothes, and other luxury items has recently decided to more all of the their on-premises infrastructure 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.
Based on cost considerations, what is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?

A. Launch a compute Instance and run a 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. B. 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. 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 a 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 data pump and then enable automatic backup- Also, enable Oracle Data Guard on the database server

Question 7

You have deployed a web application targeting a global audience across multiple Oracle Cloud Infrastructure (OCI) regions.
You decide to use Traffic Management Geo-Location based Steering Policy to serve web requests to users from the region closets to the user. Within each region you have deployed a public load balancer with 4 servers in a backend set. During a DR test disable all web servers in one of the regions however, traffic Management does not automatically direct all users to the other region.
Which two are possible causes?

A. You did not setup a Route Table associated with load Balancer's subnet B. One of the two working web servers In the other region did not pass Its HTTP health check C. You did not correctly setup the Load Balancer HTTP health check policy associated with backend set D. You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region. E. Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.
