質問 1

You are running a legacy application In a compute Instance on Oracle Cloud Infrastructure (OCI). To provide enough space for it to store internal data, a block volume is attached to the instance in paravirtualized mode. Your application is not resilient to crash-consistent backup.
What should you do to securely backup the block volume?

A. Before creating a backup, save your application data and detach the block volume.

B. Create a volume group, add the block volume and boot volume and then run the volume group backup.

C. Create a backup, detach the block volume and save your application data.

D. Use the block volume clone feature to save cost and speed up the backup process.

正解: D

質問 2

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 an HTTP Health Check associated with Load Balancer public IP in the disabled region.

B. Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.

C. You did not correctly setup the Load Balancer HTTP health check policy associated with backend set

D. You did not setup a Route Table associated with load Balancer's subnet

E. One of the two working web servers In the other region did not pass Its HTTP health check

正解: A,C

質問 3

An organization has its IT infrastructure in a hybrid setup with an on-premises environment and an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) in the us-phonix-1 region. The on-premise applications communications with compute instances inside the VPN over a hardware VPN connection. They are looking to implement an Intrusion detected and Prevention (IDS/IPS) system for their OCI environment. This platform should have the ability to scale to thousands of compute of instances running inside the VCN.
How should they architect their solution on OCI to achieve this goal?

A. There Is no need to implement an IPS/IDS system as traffic coming over IPSec VPN tunnels Is already encrypt

B. Configure autoscaling on a compute Instance pool and set vNIC to promiscuous mode to called traffic across the vcn and send it IDS/IPS platform for inspection.

C. Configure each host with an agent that collects all network traffic and sends that traffic to the IDS/IPS platform to inspection

D. Set up an OCI Private Load Balance! and configure IDS/IPS related health checks at TCP and/or HTTP level to inspect traffic

正解: C

質問 4

You are working as a solution architect for an online retail store to create a portal to allow the users to pay for their groceries using credit cards. Since the application is not fully compliant with the Payment Card Industry Data Security Standard (PCI DSS), your company is looking to use a third party payment service to process credit card payments.
The third party service allows a maximum of Spelunk IP addresses 5 public IP addresses at a time However, your website is using Oracle Cloud Infrastructure (OCI) Instance Pool Auto Scaling policy to create up to create up to 15 Instances during peak traffic demand, which are launched In VCN private in VCN private subnets and attached to an OCI public Load Balancer. Upon user payment, the portal connects to the payment service over the Interne! to complete the transaction What solution can you implement to make sure that all compute Instances can connect to the third party system to process the payments aw peak traffic demand?

A. Route payment request from the compute instances through the OCI Load Balancer, which will then be routed to the third party service.

B. Whitelist the Internet Gateway Public IP on the third party service and route all payment requests through the Internet Gateway.

C. Route credit card payment request from the compute instances through the NAT Gateway. On the third-party services, whitest the public IP associated with the NAT Gateway.

D. Create an OCI Command Line Interface (CLI) script to automatically reserve public IP address for the compute instances. On the third services, whitelist the Reserved public IP.

質問 5

A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They have decided to use both containers and servers technologies to run these application instances.
Which option should you recommend to build this new platform?

A. Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.

B. Use OCI functions, OCI object storage and OCI event service.

C. Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.

D. Install a kubernetes cluster on OCI and use OCI event service.

An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two

A. The maximum CPU cores that will be automatically allocated for this database is 16 CPUs

B. Auto scaling also scales IO throughput linearly along with CPU

C. The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling

D. Enabling auto scaling does not change the concurrency and parallelism settings

正解: B,D

質問 7

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 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.

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 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.
