Question 477 of 500

Using OCI Generative AI Service →hardMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to copy the model artifact to the secondary region’s object storage bucket and create a new dedicated endpoint there. This approach works because fine-tuned models in OCI Generative AI are stored as artifacts in Object Storage, not automatically replicated across regions; by manually copying the artifact and using automation to provision a new dedicated endpoint, you achieve disaster recovery with minimal manual effort. On the Oracle Cloud Infrastructure Generative AI Professional 1Z0-1127 exam, this question tests your understanding that cross-region model replication is not automatic—a common trap is assuming OCI handles this natively, but you must explicitly manage the artifact copy and endpoint creation. Remember the memory tip: “Artifact first, endpoint second—no auto-replication for fine-tuned models.”

1Z0-1127 Using OCI Generative AI Service Practice Question

This 1Z0-1127 practice question tests your understanding of using oci generative ai service. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 multinational corporation plans to deploy OCI Generative AI in multiple OCI regions for disaster recovery. They have fine-tuned a custom model in the primary region. What is the recommended approach to make the fine-tuned model available in the secondary region with minimal manual effort?

A
Create an IAM policy to allow cross-region access to the model from the secondary region.
Why wrong: Policies can grant access but the model artifact must be physically present in the region.
B
Use OCI Cross-Region Replication for the model's underlying object storage bucket and the dedicated AI cluster.
Why wrong: CRR replicates objects but does not automatically replicate the dedicated cluster configuration.
C
Redeploy the fine-tuning job in the secondary region using the same training data.
Why wrong: This is inefficient and duplicates effort; the model can be copied.
D
Copy the model artifact to the secondary region's object storage bucket and create a new dedicated endpoint there.
This leverages existing model artifacts and can be automated with OCI CLI or SDK.

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

✓

Copy the model artifact to the secondary region's object storage bucket and create a new dedicated endpoint there.

Option D is correct because fine-tuned models are stored in object storage; replicating the bucket and using custom automation to recreate the dedicated endpoint ensures availability. Option A is incorrect because there is no automatic cross-region replication for models. Option B is incorrect because redeploying from scratch is time-consuming. Option C is incorrect because manual policy changes are not the main issue.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Detailed technical explanation

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

Identify inside and outside interfaces first.
Check whether the scenario needs static NAT, dynamic NAT or PAT.
Do not confuse NAT matching ACLs with normal packet-filtering intent.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.

What to study next

Got this wrong? Here's your next step.

Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 1Z0-1127 NAT questions on configuration and troubleshooting.
