Exam 1z0-932 topic 1 question 56 discussion

Actual exam question from Oracle's 1z0-932

Question #: 56
Topic #: 1

You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with the database service. However, when you type the URL of this student registration application in your browser, no web page appears.
What could be the cause?

A. The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443.
B. The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.
C. The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back- end set.
D. The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.

Tricky/incomplete question. D isn't applicable, so that's out. Then the statement says the application can talk with the database, that tells me B is out, unless the health check wasnt configured properly. Leaves us with A or C. I don't think there's enough information available to definitively say it's A or , other than the bit about the 2 instances being added to the backend set of the LB. Hmmm, I'm leaning towards A.

B is wrong because LB doesn't terminate instances. C is wrong because LB does support end-to-end SSL: END TO END SSL The load balancer terminates the SSL connection with an incoming traffic client, and then initiates an SSL connection to a backend server. https://docs.cloud.oracle.com/en-us/iaas/Content/Balance/Concepts/balanceoverview.htm

default port for http and https is 80 443. So if you want to make a public website it's logical to open those ports, I think this is the reason why A is correct(but I still continue to fine the question not well done)
