An architect must communicate that a proposed Azure solution will cost approximately $50,000/month. Which approach best supports this estimate in a design document?
Answer: Include an Azure Pricing Calculator export with itemized service costs
An Azure Pricing Calculator export provides transparent, itemized, and reproducible cost estimates tied to specific service SKUs and configurations.
A design review identifies that a monolithic application cannot scale its database tier independently of the application tier. Which architectural pattern resolves this?
Answer: Decomposing to microservices with dedicated data stores per service
Microservices with dedicated data stores allow each service's persistence layer to scale independently based on its specific workload demands.
An architect is defining the recovery strategy for a Tier-1 workload with an RTO of 1 hour. Which strategy is most appropriate?
Answer: Warm standby with automated failover
A warm standby with automated failover can restore service within minutes to under an hour, meeting a 1-hour RTO without the cost of full active-active.
A project team is debating whether to use IaaS or PaaS for a new web application. Which professional consideration should drive the recommendation toward PaaS?
Answer: PaaS reduces operational overhead by abstracting OS and middleware management
PaaS abstracts OS patching, middleware updates, and infrastructure management, reducing operational burden and allowing teams to focus on application code.
An architect needs to ensure a design review covers security, reliability, cost, and operational excellence systematically. Which framework provides this structure?
Answer: Azure Well-Architected Framework
The Azure Well-Architected Framework organizes design reviews across five pillars: Reliability, Security, Cost Optimization, Operational Excellence, and Performance Efficiency.
During a stakeholder review, a business owner asks why the architect recommends Azure Front Door instead of a simple load balancer for a global web app. What is the most accurate justification?
Answer: Front Door provides global HTTP load balancing, WAF, SSL offload, and intelligent routing across regions
Azure Front Door combines global HTTP(S) load balancing, WAF, SSL termination, and latency-based routing in a single service optimized for web applications.
An architect recommends using managed identities instead of service principals with secrets for Azure resource authentication. What is the primary professional rationale?
Answer: Managed identities eliminate the need to store and rotate credentials, reducing secret sprawl risk
Managed identities are automatically managed by Azure AD and require no credential storage or rotation, eliminating a major class of credential-leakage vulnerabilities.
