The answer is to use a dedicated AI cluster with a private subnet and to store API keys in OCI Vault. These two practices work together to isolate your generative AI endpoint from the public internet and secure authentication credentials. A dedicated cluster on a private subnet ensures that all inference traffic remains within your OCI tenancy, preventing exposure to external threats, while OCI Vault centralizes API key management, allowing you to enforce IAM policies and automate key rotation instead of hardcoding secrets. On the Oracle Cloud Infrastructure Generative AI Professional 1Z0-1127 exam, this question tests your understanding of defense-in-depth for AI workloads, often pairing network isolation with secret management as a common trap where candidates mistakenly choose public endpoints or environment variables. Remember the mnemonic “Private Keys” to link the private subnet for network security with Vault for key security.
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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which TWO are best practices for securing a generative AI endpoint on OCI? (Select TWO)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Store API keys in OCI Vault
Option D is correct because OCI Vault provides a secure, centralized service for storing and managing API keys used to authenticate requests to generative AI endpoints. Storing keys in Vault prevents hardcoding them in application code or configuration files, reducing the risk of exposure and enabling automated rotation and access control via IAM policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable OCI Logging for audit
Why it's wrong here
Logging is important but not a security control.
✗
Use a public endpoint with IP restrictions
Why it's wrong here
Public endpoints are more exposed; IP restrictions can be bypassed.
✗
Disable authentication for internal use
Why it's wrong here
Disabling authentication is a security risk.
✓
Store API keys in OCI Vault
Why this is correct
OCI Vault securely manages secrets and API keys.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse logging (Option A) with a security control, or assume that IP restrictions (Option B) are sufficient for securing an AI endpoint, when in fact OCI emphasizes private endpoints and authentication as best practices.
Detailed technical explanation
How to think about this question
OCI Vault uses a Hardware Security Module (HSM) to protect cryptographic keys and secrets, ensuring they are never exposed in plaintext outside the vault. When an application needs to use an API key, it retrieves it via the Vault API using IAM-authenticated calls, which can be logged and audited. In a real-world scenario, a generative AI model deployed on a dedicated AI cluster with a private subnet (Option E) ensures that network traffic never traverses the public internet, reducing the attack surface and complying with data residency requirements.

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 network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
