Question 1
Multiple choice

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.

You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region.

C.

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

D.

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

E.

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

One of the block volumes attached to your production WebLogic server was deleted and you have tasked with identifying the source of the action. You search the Audit logs and find several Delete actions that occurred in the previous 24 hours. Given the sample of this event.

Which item from the event log helps you identify the individual or service that initiated the DeleteVolume API call?

Question 3
Single choice

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. 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.

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.

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.

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.

D.

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.

Question 4
Single choice

A data analytics company has been building Its now generation big data and analytics platform on Oracle Cloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their big data applications require such as high throughput to compute nodes with low latency file operations in addition, their data needs to be stored redundantly across multiple nodes In a single availability domain and allows concurrent connections from multiple compute Instances hosted on multiple availability domains.

Which OCI storage service can you use to meet i his requirement?

A.

Object Storage

B.

File System Storage

C.

Archive storage

D.

Block Volume

Question 5

Oracle database system is hosted in a private subnet
The private subnet route table has the following configuration.
The private subnet route table has following configuration.

However, you are still unable to connect to the Oracle Database system.

Which action will resolve this issue?

A.

Option A

B.

Option B

C.

Option C

D.

Option D

Question 6
Single choice

You have provisioned a new VM.DenseIO2.24 compute instance with local NVMe drives. The compute instance is running production application. This is a write heavy application, with a significant Impact to the business it the application goes down. What should you do to help maintain write performance and protect
against NVMe devices failure.

A.

NVMe drive have built in capability to recover themself so no other actions are required

B.

Configure RAID 6 for NVMe devices.

C.

Configure RAID 1 for NVMe devices.

D.

Configure RAID 10 for NVMe devices.

Question 7
Single choice

A civil engineering company is running an online portal In which engineers can upload there constructions photos, videos, and other digital files. There is a new requirement for you to implement: the online portal must offload the digital content to an Object Storage bucket for a period of 72 hours. After the provided time limit has elapsed, the portal will hold all the digital content locally and wait for the next offload period.

Which option fulfills this requirement?

A.

Create a pre-authenticated URL for the entire Object Storage bucket to read and list the content with an expiration of 72 hours.

B.

Create a pre authenticated URL lot each object that Is uploaded to the Object Storage bucket with an expiration of 72 hours.

C.

Create a Dynamic Group with matching rule for the portal compute Instance and grant access to the Object Storage bucket for 72 hours.

D.

Create a pre authenticated URL for the entire Object Storage bucket to write content with an expiration of 72 hours.

Question 8
Single choice

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 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.

B.

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

C.

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.

D.

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

Create two private virtual circuits on the FastConnect link. Create two Dynamic Routing Gateways, one for each VCNs. Attach the virtual circuits to the dynamic routing gateways.

B.

You cannot achieve connectivity using single FastConnect link as the production and the development VCNs-are in separate tenancies. Request one more FastConnect connection.

C.

Create a single private virtual circuit over FastConnect and attach fastConnect to either of the

D.

Create a hub-VCN that uses Dynamic Routing Gateway (DRG) to communicate with on-premises network over FastConnect. Connect the hub-VCN to the production VCN spoke and with development VCN spoke, each peered via their respective local Peering Gateway (LPG)
