問題1

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.

正確答案: A

問題2

You have been asked to create a mobile application which will be used for submitting orders by users of a popular E-Commerce site. The application is built to work with Autonomous Transaction Processing - Serverless (ATP-S) database as 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-S database is deployed with 3 CPU cores and 1 TB of memory.
Which two options are expensive or impractical ways to improve the application response times?

A. Scale up CPU core count and memory during peak times.

B. Use the Machine Learning (ML) feature of the ATP-S database iteratively to tune the SQL queries used by the application.

C. 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.

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.

正確答案: A,E

問題3

You have configured backups for your Oracle Cloud Infrastructure (OCI) 2-node RAC DB systems on virtual machines. In the console, the database backup displays a Failed status.
Which of the following options is the most likely reason for this backup issue?

A. The auth token being used by the Object Store Swift endpoint is incorrect.

B. The allocated storage on the OCI File Storage service file system attached with the database is full.

C. The RMAN backup agent is not compatible with the version of database being used.

D. The master key stored in OCI Key Management for encryption and decryption of data in the database is not accessible to the backup service.

正確答案: A

問題4

You are working as a cloud consultant 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?

A. 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.

B. 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.

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 in an OCI Object storage.

D. 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.

問題5

A customer is in a process of shifting their web based Sales application from their own data center located in US West to OCI India West (Mumbai) region. They want to do it in a controlled manner and initially only 1% of the traffic will be steered to the servers in OCI. After verification of everything is working as expected, the company is gradually planning to increase the ratio until they are comfortable with fully migrating all traffic to OCI.
Which of the following solution can be used in this situation?

A. OCI DNS and OCI Load Balancer Service

B. OCI DNS and Traffic Management with Failover Steering policy

C. OCI DNS and Traffic Management with Load Balancer Steering policy

D. OCI DNS and Traffic Management with Geolocation Steering policy

正確答案: D

問題6

You have been asked to implement a bespoke financial application in Oracle Cloud Infrastructure using virtual machine instances controlled by Autoscaling across multiple Availability Domains. The application stores transaction logs, intermediate transaction data, and audit data and needs to store this on a persistent, durable data store accessible from all of the application servers. The application requires the file system to be mounted in the /audit folder on the Linux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintain data integrity. The solution should be as low maintenance as possible.
What storage architecture should you suggest?

A. 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.

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. Use locally attached NVMe instances and configure RAID 0 replication between servers.

D. Store the data on Oracle Object Storage mounted at the /audit mount point on all the Linux instances using the default mount options.

正確答案: A

問題7

You developed a microservices based application that runs on Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). Your security team wants to use SSL termination for this application. What should you do to create a secure SSL termination for this application using fewest steps?

A. Generate a self-signed certificate using Let's Encrypt. Use that certificate on OCI Load Balancer. Create the Kubernetes service usingthis load balancer.

B. Create a self-signed certificate and it's corresponding key. Create a Kubernetes secret using the certificate and the key. Then add these an notations to the Kubernetes service:
annotations:
service.beta.kubernetes.io/oci-load-balancer-ssl-ports: "443"
service.beta.kubernetes.io/oci-load-balancer-security-list-management-mode:"Frontend"

C. Add these annotationsto the Kubernetes service:
annotations:
service.beta.kubernetes.io/oci-load-balancer-ssl-ports: "443"
service.beta.kubernetes.io/oci-load-balancer-ssl-secret-key: ssl-secret-key

D. Create a self-signed certificate and it's corresponding key. Create a Kubernetes secret using then add these annotationsto the Kubernetes service.
Service.beta.kubernete.io/oci-load-balancer-ssl-ports: "443"
Service.beta.kubernete.io/oci-load-balancer-tls-secret:SSL-CERTIFICATE-SECRET

正確答案: D
