Oracle Cloud Infrastructure 2019 Developer Associate — Question 141

You create a public Load Balancer instance and configure a back end set "BES1" with one back end server running a service on port 80. You also create a listener on port 80 and configure that listener to use the back end set "BES1". A client makes one HTTP request to the Load Balancer with the correct protocol and port.
How many connections does the Load Balancer maintain?

Answer options

Correct answer: B

Explanation

The Load Balancer maintains two connections: one for the incoming request from the client and another to the back end server to process that request. The other options do not accurately reflect the connection setup; 1, 3, and 4 do not account for the necessary connections between the client and server.
