Question 1

An Oracle Cloud Infrastructure (OCI) PublicLoad Balancer's SSL certificate is expiring soon. You noticed the Load Balancer is configured with SSL Termination only. When the certificate expires, data traffic can be interrupted and security compromised. What steps do you need to take to prevent thissituation?

A : Add the new SSL certificate to the Load Balancer, update backend servers to work with a new certificate and edit listeners so they can use the new certificate bundle

B : Add the new SSL certificate to the Load Balancer, update listeners andbackend sets so they can use the new certificate bundle.

C : Add the new SSL certificate to the Load Balancer and implement end to end SSL so it can encrypt the traffic from clients all the way to the backend servers.

D : Add the new SSL certificate to the Load Balancer and update backend servers to use the new certificate bundle.

E : Add the new SSL certificate to the Load Balancer and update listeners to use the new certificate bundle.

Answer: A

Question 2

A company runs a public-facing application that uses a Java-based web service via a RESTful API in their on-premises data center. Use of the API is expected to double with a new product launch. The business wants to migrate their application to Oracle Cloud Infrastructure (OCI) to meet the scale and reliability requirements. In order to achieve this, they will divert only 40% of the traffic to the new Apache Tomcat web servers running on OCI and serve the remaining 60% traffic through their on-premises infrastructure. Once the migration is complete and application works fine, they will divert all traffic to OCI. How can these requirements be met with the LEAST amount of effort?

A : Use OCI Traffic management service with failover steering policy and distribute the traffic between OCI and on premises infrastructure.

B : Use OCI Traffic management service with Load Balancing steering policy and distribute the traffic between OCI and on premises infrastructure

C : Use an OCI load Balancer and distribute the traffic between OCI and on premises infrastructure.

D : Use VPN connectivity between on premises Infrastructure and OCI and create routing tables to distribute the traffic between them.

Answer: B

Question 3

As a solution architect, you are designing a web application to be deployed across multiple Oracle Cloud Infrastructures (OCI) regions for a global audience. Your goal is that users from each region should access the application web servers deployed in their own geographical OCI location. Which OCI feature can be used to achieve this?

A : OCI Traffic Management IP Prefix steering policy

B : OCI Global Load balancers

C : OCI Public Load Balancers

D : OCI Traffic Management GeoLocation steering policy

Answer: D

Question 4

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 locally attached NVMe instances andconfigure RAID 0 replication between servers.

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

D : 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.

Answer: D

Question 5

You have an application running in Microsoft Azure and want to use Oracle Autonomous Data warehouse

(ADW) instance for running business analytics.

How can you build a secure solution for such a use-case?

A : Connect the Oracle ADW in your VCN to the Microsoft Azure VNet over the internet.

B : Create a software VPN connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance

C : Setup an interconnect between OCI and Microsoft Azure using FastConnect and ExpressRoute. Use a Service Gateway in OCI Virtual Cloud Network to provide connectivity to the Oracle ADW instance for the application in Microsoft Azure VNet.

D : Create a software Remote Peering Connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.

Answer: C
