You are working as a solution architect with a global automotive provider who is looking to create a multi-cloud solution. They want to run their application tier in Microsoft Azure while utilizing the Oracle DB Systems in the Oracle Cloud Infrastructure (OCI). What is the most-fault tolerant and secure solution for this customer? (Choose the best answer.)

A. Deploy the Oracle database system into a public subnet in your VCN and assign a public IP address. Connect your application tier running in Azure to the public IP address of the database system over the internet.

B. Create a FastConnect virtual circuit with Microsoft Azure as the provider to establish a private interconnect between the application tier running in the Azure Virtual Network and the OCI VCN that contains the Oracle Databases.

C. Create an encrypted, Virtual Private Network connection between the Microsoft Azure Virtual Network that contains the application tier and the OCI Virtual Cloud Network (VCN) that contains the Oracle Databases.

D. Use an OCI Virtual Cloud Network remote peering connection to create a remote network connection between the application tier running in Microsoft Azure Virtual Network and Oracle Databases running in the OCI Virtual Cloud Network (VCN).

Which of the below options is true regarding Oracle Cloud Infrastructure's load balancing service?

A. You can dynamically change the load balancer shape to handle more incoming traffic.

B. The public load balancer applies a floating public IP address to the primary load balancer.

C. When you create a private load balancer, the service requires 2 or more subnets to host both the primary and standby load balancers.

D. A public load balancer is Availability Domain specific in scope.

A fast growing E-commerce company has deployed their online shopping application on Oracle Cloud Infrastructure. The application was deployed on compute instances with Autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend. In order to promote their e-commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints. What could be two possible reasons for this situation?

A. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation.

B. As part of Autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change.

C. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.

D. Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.

You are working as a solution architect for a customer in Frankfurt, which uses multiple compute instance VMs spread among three Availability Domains in the Oracle Cloud Infrastructure (OCI) eu- frankfurt-1 region. The compute instances do not have public IP addresses and are running in private subnets inside a Virtual Cloud Network (VCN). You have set up OCI Autoscaling feature for the compute instances, but find out that instances cannot be auto scaled. You have enabled monitoring on the instances. What could be wrong in this situation?

A. You need to assign a reserved public IP address to the compute instances.

B. You need to set up a Service Gateway to send metrics to the OCI Monitoring service.

C. Autoscaling only works for instances with public IP addresses.

D. Autoscaling only works with single availability domains.

You are designing the network infrastructure for an application consisting of a web server (server-1) and a Domain Name Server (server-2) running in two different subnets inside the same Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access server-1 from the internet and server-2 from your customer's on-premises network. The on-premises network is connected to your VCN over a FastConnect virtual circuit. How should you design your routing configuration to meet these requirements?

A. Configure a single routing table with two set of rules: one that has route to internet via an Internet Gateway and another that propagates specific routes for the on-premises network via a Dynamic Routing Gateway. Don't associate this routing table with any of the subnets in the VCN.

B. Configure a single routing table with two set of rules: one that has route to internet via an Internet Gateway and another that propagate specific routes to the on-premises network via a Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.

C. Configure two routing tables: first one with a route to internet via an Internet gateway; associate this route table to the subnet containing server-1 .Configure the second route table to propagate specific routes to the on-premises network via a Dynamic Routing Gateway; associate this route table to subnet containing server-2.

D. Configure two routing tables that have rules to route all traffic via a Dynamic Routing Gateway. Associate the two routing tables with all the VCN subnets.

An eCommerce company is running on Oracle Cloud Infrastructure (OCI) and many compute instances remain unused for the most part of the year except during Black Friday and Christmas. You suggest them to use OCI's

Autoscaling feature and present them a slide to showcase the features of Autoscaling. Which option below is inaccurate in your presentation to the customer?

A. A cooldown period between Autoscaling events lets the system stabilize at the updated level.

B. When an instance pool scales in, instances are terminated in this order: the number of instances is balanced across Availability Domains, and then balanced across Fault Domains. Finally, within a Fault Domain, the newest instance is terminated first.

C. Autoscaling relies on performance metrics such as CPU utilization that are collected by OCI Monitoring service to trigger an Autoscaling event.

D. Autoscaling requires an instance pool as a pre-requisite so that it can automatically adjust the number of compute instances in an instance pool.

A cloud consultant is working on a implementation project on Oracle Cloud Infrastructure (OCI). As part of the compliance requirements, the objects placed in OCI Object Storage should be automatically archived first and then deleted.
