## 4. Executive Frequently Asked Questions (CTO / CISO / CEO Q&A)

### Q1: Who retains Intellectual Property (IP) ownership of the source code and trained SLM model weights?
The client retains **100% exclusive Intellectual Property (IP) ownership** from day one. All source code, RAG orchestration pipelines, curated training datasets, and fine-tuned model weights (LoRA / QLoRA adapters and merged checkpoints) are delivered directly into the client's private repositories and container registries with zero vendor lock-in.

### Q2: How does Nexsa Global guarantee enterprise data privacy compared to public AI APIs?
Nexsa engineers **100% sovereign deployments** inside the client's own Virtual Private Cloud (AWS VPC, Azure VNet, Google Cloud VPC) or on-premise air-gapped GPU servers (NVIDIA H100/A100) with zero public internet egress. No prompts, corporate documents, financial data, or PII are ever transmitted to external model providers.

### Q3: What is the ROI and latency advantage of a fine-tuned SLM over a generic commercial LLM?
A domain-specific Small Language Model (7B to 32B parameters such as Llama, Mistral, Qwen, or Gemma) fine-tuned on proprietary enterprise data reduces inference cost per million tokens by **65% to 85%**, lowers latency by **over 40%**, and achieves higher factual accuracy on specialized legal, medical, financial, and operational tasks.

### Q4: What are the delivery timelines from Architectural Audit to Scaled Production?
- **Phase 1 (Architectural Audit & Benchmarks)**: 1 to 2 weeks.
- **Phase 2 (Rapid Functional Prototype / Isolated Sandbox)**: Weeks 3 to 4.
- **Phase 3 (Scaled Production with CI/CD, Terraform & High Availability)**: 6 to 12 weeks depending on integration complexity.
- **Phase 4 (Continuous Governance & 24/7 SRE Observability)**: Ongoing post-launch.

### Q5: Which cybersecurity and regulatory compliance standards govern Nexsa deployments?
All architectures follow auditable **SOC2 Type II, ISO/IEC 27001, HIPAA, and GDPR** controls, including OWASP LLM Top 10 prompt-injection firewalls, automated PII redaction proxies, TLS 1.3 / AES-256 encryption, and strict multi-tenant vector isolation.

### Q6: How can an enterprise schedule an Architectural Discovery Session or submit an RFP?
- **Real-Time Calendar Booking**: Visit `https://nexsaconsulting.com/#scheduling` to select a Principal Architect (`Dr. Elena Vance`, `Marcus Chen`, or `Sarah Sterling`), choose an available 45-minute slot, and receive an encrypted `.ics` calendar invite and private management token.
- **Formal RFP Desk**: Submit technical scope specifications at `https://nexsaconsulting.com/#inquiries` or email `rfp-advisory@nexsaconsulting.com`.
