Quick Review purpose
Use this independent Quick Review to prepare for the Cisco AI Technical Practitioner (810-110 AITECH) exam from Cisco, official exam code 810-110 AITECH. It is designed for the final review stage: confirming the concepts, decision rules, and common traps you should understand before moving into topic drills, mock exams, and detailed explanations.
This page is not affiliated with Cisco and does not replace Cisco’s official exam information. It focuses on practical exam-prep review: AI fundamentals, data handling, model behavior, generative AI, AI infrastructure, networking considerations, security, governance, and operations.
High-yield review map
| Area | What to know quickly | Common exam trap |
|---|
| AI vs ML vs deep learning vs GenAI | AI is the broad field; ML learns patterns from data; deep learning uses neural networks; GenAI creates new content from learned patterns. | Treating every AI solution as generative AI or assuming all AI requires deep learning. |
| Data lifecycle | Collection, labeling, cleaning, splitting, feature engineering, validation, lineage, privacy, and monitoring. | Ignoring data quality and jumping directly to model choice. |
| Model types | Supervised, unsupervised, reinforcement learning, classical ML, neural networks, LLMs, embeddings. | Choosing a model type without checking labels, target output, latency, explainability, and data volume. |
| Evaluation | Classification, regression, clustering, ranking, GenAI quality, business impact, latency, and cost. | Optimizing one metric while missing the operational goal. |
| GenAI and LLMs | Prompts, tokens, context windows, embeddings, RAG, fine-tuning, hallucination controls, guardrails. | Assuming RAG, fine-tuning, and prompt engineering solve the same problem. |
| Infrastructure | Compute, GPU/accelerator use, memory, storage, network throughput, latency, scalability, resilience. | Designing for training needs when the workload is actually inference, or the reverse. |
| Networking for AI | East-west traffic, bandwidth, congestion, telemetry, segmentation, secure connectivity, edge/cloud placement. | Forgetting that AI performance can be limited by network and storage, not only compute. |
| Security and governance | Data protection, identity, access control, model risk, prompt injection, supply chain, auditability. | Applying only traditional app security and missing AI-specific threats. |
| MLOps/LLMOps | Versioning, deployment, model registry, monitoring, drift detection, rollback, retraining, evaluation gates. | Thinking deployment is the end of the AI lifecycle. |
Core AI concepts candidates should distinguish
AI, ML, deep learning, and generative AI
| Concept | Plain-language meaning | Typical output |
|---|
| Artificial intelligence | Systems that perform tasks associated with human-like reasoning, perception, language, or decision-making. | Prediction, recommendation, classification, generated content, automation. |
| Machine learning | Systems learn patterns from data rather than being explicitly programmed for every rule. | Class label, numeric prediction, ranking, cluster, anomaly score. |
| Deep learning | ML using multi-layer neural networks, often effective for images, speech, language, and large-scale pattern recognition. | Image labels, transcriptions, embeddings, generated text, detections. |
| Generative AI | Models that create new text, images, audio, code, or other content. | Drafts, summaries, chat responses, synthetic media, generated code. |
| Foundation model | Large pre-trained model adaptable to many downstream tasks. | General language, vision, or multimodal outputs. |
| LLM | Large language model specialized for text and language-like token prediction. | Text, code, structured responses, reasoning-like outputs. |
Exam decision rule:
If the question asks for a prediction from labeled historical examples, think supervised ML. If it asks for grouping without labels, think unsupervised learning. If it asks for content generation, summarization, conversation, or transformation, think GenAI/LLM. If it asks for interaction with an environment and rewards, think reinforcement learning.
Data lifecycle review
AI projects usually fail from poor data, weak evaluation, or operational mismatch before they fail from lack of model sophistication.

Data concepts to review
| Concept | Why it matters | Candidate mistake |
|---|
| Training data | Used to fit the model. | Letting test data influence training decisions. |
| Validation data | Used for model selection and tuning. | Treating validation results as final unbiased performance. |
| Test data | Held out for final evaluation. | Reusing the test set repeatedly until it becomes part of tuning. |
| Labels | Known answers for supervised learning. | Assuming labels exist or are reliable. |
| Features | Input variables used by the model. | Including leakage features that reveal the target indirectly. |
| Data leakage | Information from the future or target slips into training. | Getting unrealistically high test scores that fail in production. |
| Imbalanced data | One class is much more common than another. | Using accuracy when precision/recall is more relevant. |
| Data drift | Input data distribution changes over time. | Assuming a model remains valid forever. |
| Concept drift | Relationship between inputs and target changes. | Monitoring only data shape, not outcome quality. |
| Lineage | Traceability of where data came from and how it changed. | Being unable to explain, audit, or reproduce a model result. |
Data splitting trap
A random split is not always appropriate.
| Scenario | Better split approach |
|---|
| Time-series forecasting | Train on earlier time periods, validate/test on later periods. |
| User-level behavior | Split by user/account/entity to avoid leakage. |
| Medical, finance, or regulated data | Preserve privacy, auditability, and representative sampling. |
| Rare events | Use stratified splitting where appropriate. |
| Duplicated or near-duplicated records | Deduplicate or group before splitting. |
Model selection quick rules
| If the problem asks for… | Likely approach | Notes |
|---|
| Yes/no or category prediction | Supervised classification | Evaluate with precision, recall, F1, ROC-AUC, or PR-AUC. |
| Numeric prediction | Supervised regression | Evaluate with MAE, RMSE, R-squared, business error tolerance. |
| Group similar items | Clustering | No labels required; evaluation can be harder. |
| Find unusual behavior | Anomaly detection | Useful for fraud, security, sensor faults, network anomalies. |
| Recommend items | Recommendation/ranking | Consider user behavior, feedback loops, fairness, cold start. |
| Image recognition | Computer vision / CNNs / vision transformers | Data quality and labeling are critical. |
| Natural language understanding | NLP models or LLMs | Consider embeddings, context, latency, and hallucination risk. |
| Generate text or code | LLM / GenAI | Use prompts, RAG, guardrails, and evaluation. |
| Make sequential decisions with rewards | Reinforcement learning | More complex; environment and reward design matter. |
Classical ML vs deep learning vs LLMs
| Choice | Strengths | Limitations | Best fit |
|---|
| Classical ML | Often explainable, efficient, strong on tabular data. | May need feature engineering; limited for unstructured language/image tasks. | Structured business data, smaller datasets, low-latency needs. |
| Deep learning | Strong for images, speech, text, complex patterns. | Data-hungry, compute-intensive, harder to explain. | Unstructured data and large-scale pattern recognition. |
| Pre-trained foundation model | Fast adaptation, broad capabilities. | Cost, latency, privacy, hallucination, governance concerns. | Summarization, Q&A, content generation, semantic search. |
| Custom model from scratch | Maximum control. | Expensive, data-intensive, operationally complex. | Specialized needs with sufficient data, budget, and expertise. |
Evaluation metrics that show up in practice
Classification metrics
| Metric | Plain formula | Use when… | Trap |
|---|
| Accuracy | Correct predictions / total predictions | Classes are balanced and all errors have similar cost. | Misleading on imbalanced datasets. |
| Precision | TP / (TP + FP) | False positives are costly. | High precision can miss many true cases. |
| Recall / sensitivity | TP / (TP + FN) | False negatives are costly. | High recall may increase false positives. |
| F1 score | Harmonic mean of precision and recall | Need balance between precision and recall. | Hides the business meaning of each error type. |
| Specificity | TN / (TN + FP) | Need to measure true negative rate. | Not enough by itself for rare positive classes. |
| ROC-AUC | Ranking quality across thresholds | General binary classifier comparison. | Can look strong even when rare-event performance is weak. |
| PR-AUC | Precision-recall tradeoff | Imbalanced positive class. | Harder to interpret without baseline prevalence. |
Regression and forecasting metrics
| Metric | What it emphasizes | Trap |
|---|
| MAE | Average absolute error; easy to interpret. | Does not penalize large errors as heavily as RMSE. |
| RMSE | Larger errors more heavily penalized. | Sensitive to outliers. |
| R-squared | Proportion of variance explained. | Can look acceptable while business error is too high. |
| MAPE | Percentage error. | Breaks down or becomes unstable near zero values. |
GenAI and LLM evaluation
| Evaluation dimension | What to check |
|---|
| Correctness | Is the answer factually right for the context? |
| Groundedness | Is the answer supported by provided or retrieved sources? |
| Relevance | Does it answer the user’s actual request? |
| Safety | Does it avoid harmful, sensitive, or prohibited output? |
| Robustness | Does it resist prompt injection, ambiguity, and adversarial inputs? |
| Consistency | Does it provide stable behavior across similar prompts? |
| Latency | Does it respond quickly enough for the use case? |
| Cost | Are token, compute, and infrastructure costs sustainable? |
| Explainability | Can the system provide traceable rationale or citations where needed? |
Exam trap: BLEU, ROUGE, or automated similarity metrics may help for some language tasks, but they do not fully prove that an LLM answer is correct, safe, or grounded.
Generative AI and LLM review
Prompt engineering essentials
A strong prompt often includes:
- Role or task — what the model should do.
- Context — facts, documents, constraints, or user background.
- Instructions — steps, rules, and boundaries.
- Examples — desired input/output patterns.
- Output format — table, JSON, bullets, summary, classification label.
- Safety constraints — what not to reveal or perform.
- Success criteria — what a good answer should satisfy.
| Prompting technique | Use case | Trap |
|---|
| Zero-shot | Direct task with no examples. | May be inconsistent for nuanced outputs. |
| Few-shot | Provide examples of desired behavior. | Bad examples can anchor bad behavior. |
| Chain-of-thought style guidance | Encourage structured reasoning or stepwise analysis. | For production, prefer concise rationale or verifiable steps rather than exposing unnecessary internal reasoning. |
| Structured output | Need parseable JSON, tables, or labels. | Must validate output; models can still produce malformed structures. |
| System instructions | Set higher-priority behavior and boundaries. | Not a complete security control by itself. |
Tokens, context, temperature, and output control
| Concept | Meaning | Practical effect |
|---|
| Token | Unit of text processed by the model. | Drives context size, cost, and latency. |
| Context window | Maximum tokens the model can consider at once. | Long documents may need chunking or retrieval. |
| Temperature | Controls randomness. | Lower for deterministic tasks; higher for creative variation. |
| Top-p | Controls probability mass considered for generation. | Another way to tune output diversity. |
| Max tokens | Output length limit. | Too low truncates answers; too high increases cost. |
| Stop sequence | Pattern that ends generation. | Useful for structured outputs or agent boundaries. |
RAG, fine-tuning, and prompt-only approaches
| Need | Best starting approach | Why |
|---|
| Answer using current private documents | Retrieval-augmented generation | Keeps knowledge external and updateable. |
| Improve response style or format | Prompting or fine-tuning | Depends on consistency need and volume. |
| Teach new facts that change often | RAG | Updating an index is easier than retraining. |
| Specialize behavior across many examples | Fine-tuning | Useful when repeated prompt examples are not enough. |
| Reduce hallucinations from missing context | RAG plus grounding checks | The model needs access to trusted information. |
| Build from proprietary domain data at scale | Fine-tuning or custom training | Requires governance, data quality, and infrastructure. |
RAG pipeline essentials
| Step | Purpose | Common issue |
|---|
| Document ingestion | Bring source content into the system. | Untrusted, stale, or duplicate content. |
| Chunking | Split documents into retrievable pieces. | Chunks too small lose context; chunks too large reduce precision. |
| Embedding | Convert text into vectors for similarity search. | Poor embedding model for domain language. |
| Vector search | Retrieve semantically related chunks. | Retrieves similar but not authoritative content. |
| Reranking | Improve result ordering. | Adds latency but can improve relevance. |
| Prompt assembly | Combine user question and retrieved context. | Context overflow or irrelevant context. |
| Generation | Produce final answer. | Hallucination, overconfidence, missing citations. |
| Evaluation | Measure correctness and groundedness. | Relying only on user satisfaction. |
Decision rule:
Use RAG when the model needs trusted, updateable, external knowledge. Use fine-tuning when the model needs consistent behavior, tone, format, or task adaptation that prompts cannot reliably achieve.
AI infrastructure and networking review
For a Cisco exam, connect AI concepts to technical infrastructure: where data moves, how workloads scale, how systems are secured, and how networks support high-throughput, low-latency operations.
Training vs inference
| Dimension | Training | Inference |
|---|
| Goal | Learn model parameters from data. | Use a trained model to produce outputs. |
| Compute pattern | Heavy, often distributed, accelerator-intensive. | Latency-sensitive, may need autoscaling. |
| Data flow | Large datasets, checkpoints, repeated reads/writes. | Requests and responses, sometimes retrieval calls. |
| Network concern | High east-west traffic between nodes; synchronization. | User latency, API throughput, availability. |
| Storage concern | Dataset access, checkpointing, versioning. | Model loading, cache, retrieval index access. |
| Optimization | Throughput, utilization, parallelism. | Latency, concurrency, cost per request. |
| Failure impact | Lost training time, checkpoint recovery. | User-facing outage or degraded service. |
Infrastructure bottlenecks
| Symptom | Likely area to investigate |
|---|
| GPUs underutilized during training | Data pipeline, storage throughput, network bottleneck, small batch size. |
| Training fails intermittently | Node failure, network instability, memory exhaustion, dependency mismatch. |
| Inference latency is high | Model size, cold starts, retrieval delay, network path, overloaded service. |
| RAG answers are slow | Vector database latency, reranking, large context, too many retrieval calls. |
| Model loads slowly | Storage performance, image size, model artifact location. |
| Cost spikes | Overprovisioned accelerators, excessive tokens, inefficient batching, poor autoscaling. |
| Production accuracy drops | Data drift, concept drift, upstream data changes, label delay. |
Networking concepts for AI workloads
| Concept | Why it matters |
|---|
| Bandwidth | Large datasets, distributed training, and model artifacts can move significant traffic. |
| Latency | Affects user-facing inference, API chains, RAG retrieval, and distributed synchronization. |
| East-west traffic | AI clusters often communicate heavily between compute nodes. |
| Congestion management | Prevents throughput collapse under high load. |
| Segmentation | Isolates sensitive data, model services, management planes, and tenants. |
| Telemetry | Helps detect bottlenecks, errors, drops, latency, and capacity issues. |
| Resilience | AI services need redundancy, failover, and graceful degradation. |
| Edge placement | Reduces latency and bandwidth use when data is generated near users or devices. |
| Secure connectivity | Protects data in transit and controls access to models and APIs. |
Cloud, on-premises, hybrid, and edge placement
| Placement | Strengths | Tradeoffs |
|---|
| Public cloud | Elastic capacity, managed AI services, rapid experimentation. | Cost control, data residency, egress, shared responsibility complexity. |
| On-premises data center | Control, proximity to sensitive data, predictable governance. | Capacity planning, hardware cost, operational responsibility. |
| Hybrid | Balance control with cloud flexibility. | Integration, identity, network, and policy consistency. |
| Edge | Low latency, local autonomy, reduced backhaul. | Limited compute, lifecycle management, physical security. |
Exam decision rule:
If the requirement emphasizes real-time response near devices, consider edge inference. If it emphasizes massive training capacity and elasticity, cloud may fit. If it emphasizes data control, compliance, or existing private infrastructure, on-premises or hybrid may be favored.
Security, privacy, and responsible AI
Traditional security still applies
AI systems still need normal enterprise controls:
- Strong identity and access management.
- Least privilege.
- Encryption in transit and at rest.
- Network segmentation.
- Secure APIs.
- Logging and monitoring.
- Vulnerability management.
- Backup and recovery.
- Supply chain control.
- Incident response.
AI-specific risks
| Risk | What it means | Mitigation direction |
|---|
| Prompt injection | User or retrieved content attempts to override instructions. | Input isolation, instruction hierarchy, content filtering, tool-use controls. |
| Data leakage | Sensitive information appears in prompts, logs, training data, or outputs. | Data classification, redaction, access control, retention limits. |
| Model inversion | Attacker infers training data from model behavior. | Privacy controls, output limits, careful training data governance. |
| Model theft | Unauthorized copying or extraction of model behavior. | API rate limits, monitoring, access controls, watermarking where appropriate. |
| Poisoning | Malicious data affects training or retrieval. | Data validation, trusted sources, lineage, anomaly detection. |
| Hallucination | Model produces plausible but false content. | RAG, citations, confidence handling, human review for high-risk tasks. |
| Bias and unfairness | Model performance differs across groups. | Representative data, fairness testing, monitoring, governance review. |
| Unsafe tool use | Agent or model takes harmful action through connected tools. | Permission boundaries, approvals, sandboxing, audit logs. |
| Shadow AI | Unapproved AI use with sensitive data. | Policy, approved tools, monitoring, user education. |
Responsible AI review points
| Principle | Practical meaning |
|---|
| Transparency | Users and stakeholders understand AI involvement and limitations. |
| Accountability | Owners are defined for model behavior, data, and incidents. |
| Fairness | Systems are tested for harmful bias and unequal impact. |
| Privacy | Personal and sensitive data is protected throughout the lifecycle. |
| Safety | Outputs and actions are controlled for harmful outcomes. |
| Reliability | System behavior is monitored and validated over time. |
| Explainability | Decisions can be understood at the level required by the use case. |
Common trap: Responsible AI is not only a documentation exercise. It affects data selection, model evaluation, deployment controls, user experience, monitoring, and incident response.
MLOps and LLMOps review
What must be versioned
| Artifact | Why version it |
|---|
| Dataset | Reproduce training and investigations. |
| Labels | Track changes in ground truth. |
| Feature definitions | Prevent silent changes in model inputs. |
| Code | Rebuild the pipeline. |
| Model artifact | Know exactly what is deployed. |
| Hyperparameters | Reproduce training behavior. |
| Prompt templates | Control LLM behavior changes. |
| Retrieval index | Trace RAG answer sources. |
| Evaluation set | Compare versions consistently. |
| Configuration | Reproduce deployment and runtime behavior. |
Deployment patterns
| Pattern | Use case | Watch for |
|---|
| Batch inference | Periodic scoring, reports, offline recommendations. | Freshness and scheduling. |
| Real-time inference | User-facing predictions or chat. | Latency, availability, scaling. |
| Streaming inference | Continuous data such as telemetry or sensors. | Throughput, ordering, backpressure. |
| Canary deployment | Release to small percentage first. | Monitoring and rollback criteria. |
| Blue-green deployment | Switch between old and new environments. | Compatibility and cutover control. |
| A/B testing | Compare model variants. | Statistical validity and user impact. |
| Human-in-the-loop | High-risk or ambiguous decisions. | Workflow design and escalation. |
Monitoring after deployment
| Monitor | Why it matters |
|---|
| Input data quality | Detect missing, invalid, or shifted inputs. |
| Prediction distribution | Identify unexpected output patterns. |
| Latency and errors | Maintain service reliability. |
| Resource utilization | Control cost and performance. |
| Business outcomes | Confirm model value. |
| Ground truth performance | Measure accuracy when labels arrive. |
| Drift | Decide whether retraining is needed. |
| Safety events | Detect harmful outputs or policy violations. |
| User feedback | Capture quality issues not visible in metrics. |
Drift distinctions
| Type | Meaning | Example |
|---|
| Data drift | Input distribution changes. | User behavior shifts after a new product launch. |
| Concept drift | Relationship between inputs and target changes. | Fraud patterns change after attackers adapt. |
| Prediction drift | Output distribution changes. | Model suddenly predicts one class more often. |
| Performance drift | Actual measured accuracy or usefulness declines. | Validation-like performance no longer matches production. |
Exam decision rule:
If inputs changed, think data drift. If the meaning of inputs changed relative to outcomes, think concept drift. If outputs changed, think prediction drift. If measured quality dropped, think performance drift.
Common scenario decisions
Which metric should be prioritized?
| Scenario | Better metric focus |
|---|
| Detecting a dangerous condition where missing it is costly | Recall / sensitivity |
| Alerting analysts where too many false alarms waste time | Precision |
| Balanced classification with similar error costs | Accuracy may be acceptable |
| Rare-event detection | Precision, recall, F1, PR-AUC |
| Numeric forecast with large errors especially harmful | RMSE |
| Numeric forecast needing easy business interpretation | MAE |
| LLM answers for internal knowledge base | Groundedness, correctness, citation quality, latency |
| AI assistant with connected tools | Safety, authorization, auditability, task success |
Which control reduces which GenAI risk?
| Requirement | Strong control |
|---|
| Keep answers tied to company documents | RAG with trusted sources and citations. |
| Prevent sensitive data exposure | Data loss prevention, redaction, access controls, logging policy. |
| Stop model from taking unauthorized actions | Tool permission boundaries and approval workflows. |
| Reduce prompt injection impact | Treat retrieved/user content as untrusted, constrain tools, validate outputs. |
| Improve consistent response format | Structured prompts, schema validation, possibly fine-tuning. |
| Improve factual currency | Retrieval from updated sources, not static model memory. |
| Investigate bad answers | Trace prompts, model version, retrieved chunks, user context, logs. |
Which infrastructure issue is most likely?
| Clue in question | Likely answer direction |
|---|
| “High GPU cost but low utilization” | Data/input pipeline or scheduling inefficiency. |
| “Model works in lab but fails with live traffic” | Production data mismatch, scaling, latency, drift, or integration issue. |
| “Private data cannot leave environment” | On-premises, private cloud, hybrid controls, or local inference. |
| “Need milliseconds of response near devices” | Edge inference or local processing. |
| “Need to query changing internal documents” | RAG and document indexing. |
| “Responses cite wrong or stale policy” | Retrieval source quality, index freshness, chunking, or ranking. |
| “Users can make the assistant ignore instructions” | Prompt injection and insufficient guardrails. |
| “Accuracy high but minority class missed” | Class imbalance; use recall, precision, F1, PR-AUC. |
Candidate mistakes to avoid
- Confusing training and inference. Training creates or updates the model; inference uses it.
- Using accuracy by default. Accuracy can be the wrong metric for imbalanced or high-risk cases.
- Ignoring data leakage. Leakage creates impressive but false performance.
- Assuming bigger models are always better. Larger models can increase cost, latency, risk, and complexity.
- Treating prompts as security boundaries. Prompts guide behavior but do not replace access control and validation.
- Choosing fine-tuning when RAG is the better answer. New or private facts usually belong in retrieval, not model weights.
- Forgetting monitoring. AI behavior can degrade after deployment.
- Overlooking network and storage bottlenecks. AI workloads are not only compute problems.
- Ignoring governance. Data lineage, auditability, privacy, and responsible AI are part of production readiness.
- Missing the business goal. The best technical metric may not match the operational requirement.
