質問 # 82
Case Study 1 - Fabrikam Inc.
Background
Fabrikam Inc. is a global retail analytics company that provides AI-driven demand forecasting and product recommendation services to online retailers. The company is modernizing its solution to run entirely on Microsoft Azure.
The platform ingests transaction data, generates embeddings for semantic retrieval, performs vector similarity search, and returns product recommendations through containerized microservices. Developers use Python and Azure SDKs. Operations teams manage container orchestration, scaling, monitoring, and security.
The solution must meet strict performance, scalability, and security requirements.
Current environment
Application architecture
The Recommendation engine is a customer-facing HTTP API running as a containerized Python application. The engine is deployed to Azure Container Apps (ACA).
Embeddings are stored in Azure Database for PostgreSQL by using pgvector.
Semantic retrieval uses metadata filtering combined with vector similarity search.
Azure Managed Redis is used as a caching layer.
Front-end and API workloads are deployed to Azure Container Apps (ACA).
Batch model retraining workloads run in Azure Kubernetes Service (AKS).
Container and CI/CD
Container images are stored in Azure Container Registry (ACR).
CI/CD uses ACR Tasks to build images on commit.
ACA environments support revision management.
AKS workloads are deployed by using Kubernetes manifest files stored in Git.
Monitoring
Logs are collected in Azure Monitor.
Teams inspect container logs and Kubernetes events when troubleshooting.
Developers write KQL queries to analyze latency spikes.
Business requirements
Customer experience: Maintain a seamless, low-latency recommendation experience for end- users, even during unpredictable seasonal traffic spikes.
Operational cost efficiency: Minimize compute expenditures by deallocating resources during periods of inactivity and by preventing runaway scaling costs.
Data integrity and freshness: Ensure that product recommendations always reflect the most current catalog metadata and pricing to prevent customer dissatisfaction.
Security and compliance: Adhere to a Zero Trust security model by eliminating long-lived credentials and centralizing the management of all sensitive secrets.
Global scalability: Support the rapid ingestion of millions of new product embeddings daily without degrading query performance for existing retailers.
Technical requirements
Performance: Semantic search latency must remain under 200 milliseconds at peak load.
Database optimization: Use pgvector for embeddings and implement metadata filtering to reduce compute overhead. Configure compute and memory appropriately for vector workloads to ensure high-dimensional index residency in RAM and efficient mathematical throughput. Vector similarity calculations must be performed only against products that satisfy mandatory metadata constraints.
Database performance: Database connections must support high concurrency with minimal latency through the implementation of connection optimization.
Data load strategy: To ensure maximum ingestion throughput, secondary indexes must be applied only after bulk loading of embeddings is complete.
Caching: Redis cache entries must expire automatically after 10 minutes. Implement a reactive mechanism to invalidate cache entries upon metadata updates.
Identity: Use managed identities for all service-to-service and service-to-database authentication.
Plain-text credentials in configuration files are strictly prohibited.
Secret management: All secrets must be stored centrally. Secrets must be rotated automatically by using a centralized lifecycle policy.
Scaling: Use Kubernetes event-driven autoscaling (KEDA) for event-driven scaling. The Recommendation API must scale based on HTTP traffic, while batch jobs must scale based on queue length and support scale-to-zero.
CI/CD: All images must be stored in Azure Container Registry. Use ACR Tasks to automate image builds triggered by source code commits.
Monitoring: Use KQL to analyze performance telemetry and troubleshoot microservice connectivity failures. Inspect logs and events when troubleshooting AKS and ACA.
Drag and Drop Question
You need to configure the Redis integration for the Recommendation API.

正解：
解説：
Explanation:
Scenario, Application: Azure Managed Redis is used as a caching layer.
Box 1: Configure the Time to Live (TTL) on each cache key
You must configure the Time to Live (TTL) on each cache key to meet this requirement. Azure Managed Redis (like standard Redis) does not support a global, database-wide default TTL configuration for newly created keys.
Scenario: Technical requirements: Caching: Redis cache entries must expire automatically after
10 minutes.
Box 2: Publish invalidation events to a Redis channel
Publishing invalidation events to a Redis Pub/Sub channel is a highly effective, standard architecture to invalidate cache entries across microservices or application nodes. It establishes a reactive, event-driven backplane that ensures system data integrity without requiring tight coupling between your database updates and web servers.
Scenario: Technical requirements: Implement a reactive mechanism to invalidate cache entries upon metadata updates.
Box 3: Implement the cache-aside pattern with lazy loading
To meet your search latency target for recurring product requests, you should implement the cache-aside pattern with lazy loading.
Directly reduces latency: Lazy loading ensures that frequently requested product data is kept in memory (Redis), allowing subsequent recurring requests to bypass the slower database completely.
Optimizes memory usage: Data is only loaded into the cache when actually requested, preventing your Azure Managed Redis instance from filling up with rarely accessed product data.

質問 # 83
You are designing an Azure Function that will process orders from a new Azure Service Bus queue.
You need to prevent the system from processing messages more than once and preserve failed messages for investigation.
Which two actions should you implement? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
正解：B、D
解説：
To ensure reliable order processing with zero duplicates and safe error handling, you should implement an Azure Function with an Azure Service Bus Trigger utilizing duplicate detection, PeekLock settlement, and custom dead-letter routing.

Hotspot Question
You are developing a Retrieval-Augmented Generation (RAG) solution for a company.
AI responses and embedding vectors are cached in Redis.
The solution must meet the following requirements:
- AI responses must expire exactly 24 hours after they are cached.
- Cached embeddings must always reflect the current source data.
You need to configure Redis to meet the requirements.
NOTE: Each correct selection is worth one point.
正解：
解説：
Explanation:
Box 1: Set a Time for Live (TTL) on each key.
To configure Redis to expire your AI responses exactly 24 hours after caching, you must apply a Time-To-Live (TTL) of 86,400 seconds to the specific keys holding those responses.
Box 2: Delete related keys when the document changes
You must invalidate or update those cached keys when source data changes to prevent your RAG system from retrieving stale information.
Incorrect:
Configuring allkeys-lru (Least Recently Used) is not recommended to ensure your cached embeddings or AI responses reflect current source data.allkeys-lru is an eviction policy. It only deletes data when Redis reaches its maximum memory limit, and it targets keys that haven't been accessed recently. It does not verify if the underlying source data has changed, meaning users will get dangerously outdated (hallucinated) AI responses if the source document is updated but the cached response remains in memory.

質問 # 86
Hotspot Question
You plan to deploy an Azure Container Apps app named App1. App1 will use an access key to connect to a backend API.
The solution must store the key outside of the App1 environment and minimize maintenance efforts.
You need to configure secure key storage for App1.
Which configurations should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
正解：
解説：
Explanation:
Box 1: Azure Key Vault secret.
The key should be stored as an Azure Key Vault secret.
This option directly satisfies the requirement to store sensitive strings (like access keys or API keys) outside of the application environment. By leveraging Azure Key Vault references in Azure Container Apps, the Container Apps platform automatically pulls the secret value at runtime. If you leave out the specific version tag in the secret URI, Azure Container Apps will automatically fetch the latest version within 30 minutes of a rotation, drastically minimizing ongoing maintenance efforts.
Incorrect:
Azure Key Vault Key: This is incorrect because Key Vault keys are cryptographic key material used strictly for cryptographic operations (such as encryption, decryption, and signing). They do not return plaintext secret data to your application, making them unsuited for raw API string storage.
Azure Container Apps secret: While easy to implement natively, this option stores the key inside the Container App environment scope. It fails the requirement to keep the key entirely separated from the application environment and requires manual application updates if the backend key changes or rotates.
Box 2: Managed identity
You should use a Managed identity.
Zero Secret Lifecycle Management: A managed identity provides an automatically managed identity in Microsoft Entra ID. Azure handles credential rotation automatically, completely eliminating maintenance efforts and the risk of leaked credentials.
Native Platform Integration: Azure Container Apps natively supports managed identities to authenticate with Azure Key Vault. You can directly reference Key Vault secrets in your Container App configuration without writing custom authentication code inside the container.
