- A
Use a site-to-site VPN to connect clients to the VCN and access the endpoint via private IP.
Why wrong: VPN provides encrypted connectivity but requires a public endpoint for VPN termination; also adds complexity and latency.
- B
Remove the load balancer and use a service gateway to access the model deployment directly from the VCN.
Why wrong: A service gateway allows private access but does not provide load balancing or SSL termination.
- C
Keep the public load balancer but add a Web Application Firewall (WAF) to block unauthorized IPs.
Why wrong: WAF filters traffic but does not make the endpoint private; it remains publicly accessible.
- D
Replace the public load balancer with a private load balancer in a private subnet, and attach an SSL certificate for encryption.
A private load balancer is not internet-facing, ensures encryption via SSL, and provides high availability.
Quick Answer
The correct choice is to replace the public load balancer with a private load balancer in a private subnet and attach an SSL certificate for encryption. This directly addresses the security requirement of securing a model endpoint with a private load balancer on OCI by removing public internet exposure while maintaining encryption in transit. On the Oracle Cloud Infrastructure Generative AI Professional 1Z0-1127 exam, this scenario tests your understanding that a private load balancer, placed in a private subnet, still provides high availability and low latency through internal VCN routing, and that TLS termination at the load balancer satisfies the encryption mandate. A common trap is assuming a public load balancer with an SSL certificate is sufficient—but public accessibility remains the vulnerability. Remember the key distinction: public load balancer = internet-facing; private load balancer = VCN-internal only. For the exam, think “private subnet, private LB, plus SSL” as the triple requirement for a secure, non-public endpoint.
1Z0-1127 Deploying and Managing Generative AI on OCI Practice Question
This 1Z0-1127 practice question tests your understanding of deploying and managing generative ai on oci. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A large enterprise is deploying a generative AI model for internal document summarization. The model is deployed on OCI Data Science using a custom container. The inference endpoint is behind a public load balancer. The security team requires that all traffic between the client and the endpoint be encrypted in transit and that the endpoint not be accessible from the public internet. The current setup uses a public load balancer with an SSL certificate. The VCN has a public subnet for the load balancer and a private subnet for the model deployment. The security team is concerned that the load balancer is publicly accessible. The enterprise wants to maintain high availability and low latency. What should the architect do to meet the security requirements?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Replace the public load balancer with a private load balancer in a private subnet, and attach an SSL certificate for encryption.
Option D is correct because replacing the public load balancer with a private load balancer in a private subnet ensures the endpoint is not accessible from the public internet, while attaching an SSL certificate maintains encryption in transit. This satisfies both security requirements without sacrificing high availability or low latency, as the private load balancer still provides load balancing and TLS termination within the VCN.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think a WAF or VPN alone can satisfy both encryption and private access, but they overlook that the public load balancer itself remains a publicly routable endpoint, which directly violates the 'not accessible from the public internet' requirement.
Detailed technical explanation
How to think about this question
A private load balancer in OCI is assigned a private IP address from the private subnet and is only reachable within the VCN or via connected networks (e.g., VPN, FastConnect). SSL termination at the load balancer decrypts traffic before forwarding to the backend model deployment, which can be configured to accept only HTTP traffic from the load balancer, reducing attack surface. This architecture supports high availability through load balancer health checks and automatic failover across backend instances, while maintaining low latency by keeping traffic within the OCI network.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
