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?
You are working on the migration of the web application infrastructure of your company from on-premises to Oracle Cloud Infrastructure. You need to ensure that the DNS cache entries of external clients will not direct them to the on-premises infrastructure after switching to the new infrastructure.
Which of the following options will minimize this problem?
As part of planning the network design on Oracle Cloud Infrastructure, you have been asked to create an Oracle Cloud Infrastructure Virtual Cloud Network (VCN) with 3 subnets, one in each Availability Domain. Each subnet needs to have a minimum of 64 usable IP addresses.
What is the smallest subnet and VCN size you should use to implement this design? The requirements are static, so no growth is expected.
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?
