1Z0-1072-25 Question 142
Select 2You have an e-commerce application running on multiple compute instances in Oracle Cloud Infrastructure. The application requires SSL termination at the load balancer and cookie-based session persistence to ensure that users remain connected to the same backend instance for the duration of their session. Which two steps should you perform to configure the appropriate load balancer in Oracle Cloud Infrastructure to meet these requirements?
- A
Create an OCI Network Load Balancer and enable a custom TCP-based cookie option for session persistence.
- B
Configure an HTTPS listener on an OCI Load Balancer and upload your SSL certificate for termination.
- C
Set up a path-based routing rule on the OCI Network Load Balancer to examine HTTP headers and cookies for layer-7 routing capabilities.
- D
Configure a UDP health check for your backend set to improve performance under SSL termination.
- E
Enable cookie-based session persistence in the OCI Load Balancer backend set.
Show answer and explanation
Correct answers: B, E
Explanation
Oracle Cloud Infrastructure Load Balancer (sometimes referred to as the 'Public Load Balancer' or 'Private Load Balancer' depending on subnet configuration) provides layer-7 features such as SSL/TLS termination and the ability to configure cookie-based session persistence. Network Load Balancer, by contrast, operates at layer 4 and does not support these more advanced HTTP or HTTPS functions. For more information, refer to the official OCI Load Balancing documentation at https://docs.oracle.com/en-us/iaas/Content/Balance/Concepts/balanceoverview.htm.
- A. Incorrect.
Option 1 is incorrect because Network Load Balancer in OCI does not support advanced features such as HTTPS-based SSL termination or cookie-based session persistence. It operates at layer 4 and cannot handle HTTP/HTTPS-specific session cookies.
- B. Correct.
Option 2 is correct. An OCI Load Balancer allows you to configure an HTTPS listener by uploading the SSL certificate. This offloads SSL termination at the load balancer, a requirement for your e-commerce application.
- C. Incorrect.
Option 3 is incorrect. Network Load Balancer does not perform layer-7 routing. Path-based or host-based routing rules that examine HTTP headers or cookies are features of the OCI Load Balancer (layer-7).
- D. Incorrect.
Option 4 is incorrect. Although health checks are important, using UDP as a health check protocol does not meet HTTPS-based requirements. For SSL termination, you typically use HTTP or HTTPS health checks, not UDP.
- E. Correct.
Option 5 is correct. The OCI Load Balancer supports cookie-based session persistence in the backend set configuration, which ensures users remain connected to the same backend instance, fulfilling the requirement for consistent sessions.
