1Z0-1072-25 Question 141
Select 2Your organization is deploying a new analytics platform in Oracle Cloud Infrastructure (OCI). The platform includes an HTTP-based web front end that requires path-based routing to distribute user traffic to different microservices, and a real-time engine that communicates via UDP. You want to ensure both traffic types are properly balanced while keeping the solution as straightforward as possible. Which two configuration steps are needed to meet these requirements?
- A
- Configure a single Network Load Balancer that supports both advanced path-based routing and UDP pass-through on the same listener.
- B
- Deploy a public (Layer 7) Load Balancer to handle path-based routing for the HTTP front end, and a separate Network Load Balancer for UDP traffic.
- C
- Use a single public Load Balancer with separate back-end sets to handle both HTTP and UDP traffic on different ports.
- D
- Create path-based routing rules on the Layer 7 Load Balancer for the /analytics path, directing HTTP requests to the analytics back-end set.
Show answer and explanation
Correct answers: B, D
Explanation
In OCI, the traditional Layer 7 Load Balancer supports path- and hostname-based routing and SSL/TLS termination for HTTP(s) traffic. However, it does not handle UDP traffic, which is where the Network Load Balancer excels. By deploying these two load balancers separately�one for HTTP path-based routing and another for UDP�organizations can effectively meet both requirements. Refer to official OCI documentation (Load Balancer and Network Load Balancer guides) for details on setting up listeners, back-end sets, and routing rules.
- A. Incorrect.
Option 1 is incorrect. A Network Load Balancer, operating at Layer 4, does not provide advanced Layer 7 features such as path-based routing. While it can pass UDP traffic, it cannot manage path-based HTTP rules.
- B. Correct.
Option 2 is correct. A public (Layer 7) Load Balancer handles HTTP traffic and path-based routing, while a separate Network Load Balancer can manage UDP traffic. This combination addresses both application requirements.
- C. Incorrect.
Option 3 is incorrect. A single Layer 7 Load Balancer cannot natively handle UDP traffic. OCI� Layer 7 Load Balancer is built for HTTP/HTTPS traffic and does not pass UDP packets to back-end servers.
- D. Correct.
Option 4 is correct. Layer 7 routings such as path-based rules are configured on the public Load Balancer to direct HTTP requests to the correct back-end set (e.g., /analytics -> analytics service).
