The practice bank includes 400 questions for Oracle 1Z0-1158-26, so you can review the exam steadily instead of relying on one long cram session.
As you practice, pay extra attention to recurring topics such as OCI Generative AI Services, Large Language Models (LLMs), AI Agents and Orchestration, Retrieval-Augmented Generation (RAG), and Vector Databases and Embeddings. Start with short sessions to identify weak areas, then move into timed quizzes once your accuracy is consistent.
The explanations are written for candidates preparing for Oracle certification questions and reviewing how the concepts apply in practice. Use the free preview first, then unlock the full question bank when you are ready to build a complete study routine.
Sample Questions
5 sample questions with answers and explanations. The full bank has 400 questions, enough for 6 full-length practice exams.
Preview — answers shown1. Which vendor supplies the Voice model family — providing text-to-speech capability — within OCI Enterprise AI? (Select one!)
ACohere
BGoogle
CMeta
DxAI
Explanation
Within OCI Generative AI / Enterprise AI pretrained models catalog, the model families are categorized by capability: Chat (Cohere, Google, Meta, OpenAI), Embed (Cohere), Voice (xAI Voice TTS), and Rerank. Therefore, xAI supplies the Voice model family for text-to-speech capabilities.
2. According to the OCI hosted agent container contract, on which address and port must the container's HTTP server listen? (Select one!)
A0.0.0.0:443
B127.0.0.1:8080
C0.0.0.0:80
D0.0.0.0:8080
Explanation
The OCI hosted agent container contract mandates listening on 0.0.0.0:8080, binding to all network interfaces on port 8080. Listening on 127.0.0.1:8080 restricts the server to loopback traffic only, making it unreachable by the platform's health probes and load balancer. Port 443 is reserved for HTTPS and port 80 for standard HTTP; neither matches the required port 8080. The 0.0.0.0 bind address is required, not an arbitrary interface IP.
3. Which OCI IAM resource type belongs in an allow policy that grants a group permission to invoke OCI Generative AI resources? (Select one!)
Aenterprise-ai-resources
Bgenerative-model-family
Cai-service-family
Dgenerative-ai-family
Explanation
OCI IAM policies use generative-ai-family as the resource type for OCI Generative AI permissions. ai-service-family, enterprise-ai-resources, and generative-model-family are not the documented IAM resource-type token for these service resources.
4. Your accessibility roadmap requires adding text-to-speech narration to an OCI Enterprise AI application so visually impaired users can hear AI-generated summaries aloud. Which OCI Enterprise AI model family provides this capability? (Select one!)
ARerank
BChat
CVoice
DEmbed
Explanation
The Voice model family within OCI Enterprise AI is dedicated to text-to-speech generation, converting text input into spoken audio output. The Chat family handles text generation, multi-turn conversation, and reasoning. The Embed family produces vector embeddings from text or image inputs for use in semantic search and RAG pipelines. The Rerank family scores and reorders already-retrieved results for relevance. Generating audio is the exclusive function of the Voice family among these four.
5. An engineering manager reviews language-support requirements for a team that will call the OCI Responses API through a compatible OpenAI SDK. Which three languages appear on Oracle's documented OpenAI SDK support list? (Select three!)
Multiple correct answersATypeScript
BJava
CSwift
DPython
ERuby
FKotlin
Explanation
Oracle's OCI Responses API documentation lists Python, Java, TypeScript, Go, and .NET for compatible OpenAI SDK use. Among these options, Python , Java , and TypeScript are listed. This is specifically the OpenAI SDK compatibility list for the OCI Responses API, not the broader OCI SDK language list, which also includes Ruby.
