You are deploying a highly available web application in Oracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs).
How many subnets should you create to deliver a secure, highly available application?

  • A. three subnets in total; one subnet in each AD
  • B. five subnets in total; two subnets each in the first and second AD with a single subnet in the third AD
  • C. six subnets in total; two subnets in each AD; one for the load balancer and one for the web servers
  • D. four subnets in total; one subnet in each AD for the web servers and a single subnet in any one AD for the load balancer

Correct Answer is B. Each webserver requires one Subnet. 3 Subnets. Load Balancer can configured as Regional Service or with 2 Availability Domains. In this case its 2 ADs. 3+2 = 5. B is correct answer

D is the Answer for this version for exam in 2019. In late 2019 Oracle released Regional Subnets and with that introduced for current exam version all these answers are wrong. Correct Answer is : 2 Subnets , One private Regional subnet for all Web servers spanning across 3 AD and one Public regional subnet for LB which will allow HA functionality for LB

So do we need to select answer as per 2019 concepts in the 2019 exam? I have my 2019 version exam tomorrow but with current concepts (2020) I will go with 5 subnets in the given options. 2 public subnets for LB and 3 private/public subnets for web servers. Please correct my understanding.

Oracle has updated the options now and correct answer is 2 Regional subnets required, 1 public for Load Balancer and 1 private for servers.

The logic of letter B is that 5 subnets. 2 subnets each on AD 1 and AD2 and 1 subnet on AD3. The statement did not include a subnet for the public load balancer. So my answer is D.

Reading this page with focus on the Architecture picture, I would choose the answer C: https://docs.oracle.com/en/solutions/ha-web-app/#GUID-1072426F-EAAE-4F32-9F90-5873DE04313B

Answer A. A public load balancer is regional in scope. If your region includes multiple availability domains, a public load balancer requires either a regional subnet (recommended) or two availability domain-specific (AD-specific) subnets, each in a separate availability domain. With a regional subnet, the Load Balancing service creates a primary load balancer and a standby load balancer, each in a different availability domain, to ensure accessibility even during an availability domain outage. If you create a load balancer in two AD-specific subnets, one subnet hosts the primary load balancer and the other hosts a standby load balancer. If the primary load balancer fails, the public IP address switches to the secondary load balancer. The service treats the two load balancers as equivalent and you cannot specify which one is "primary".

"C. six subnets in total; two subnets in each AD; one for the load balancer and one for the web servers" If I understood it correctly, you will end up having 3 load balancers. Each AD has a load balancer. We need just 2. (C) is wrong.

I Would go with D . https://docs.cloud.oracle.com/en-us/iaas/Content/Balance/Concepts/balanceoverview.htm#:~:text=Oracle%20recommends%20that%20you%20create,domains%20within%20the%20region. Oracle recommends that you create your load balancer in a regional subnet. Oracle recommends that you distribute your backend servers across all availability domains within the region.
