Designing Microsoft Azure Infrastructure Solutions AZ-305 Practice Test 3
Question 20
A change advisory board requests objective evidence for this design target: A platform team must send custom application records through a governed ingestion schema and transformation. Which verification is most relevant?
a new resource log record appears in the configured workspace table.
an Event Hubs consumer receives entries matching the configured categories.
monitored machines appear with guest performance charts and dependency information.
transformed custom records are visible in the target Log Analytics table.
Explanation
Correct Answer
D:
D is the best answer for the stated workload. Use the Azure Monitor Logs ingestion API with a data collection rule is appropriate because the ingestion API applies DCR-controlled streams and transformations to custom logs. The observable acceptance condition is that transformed custom records are visible in the target Log Analytics table. That observation directly checks the required operational behavior rather than a mere configuration setting.
Incorrect Answers
A:
A would instead validate the other design where a team needs supported Azure resource logs sent to a centralized workspace without changing application code. That evidence is consistent with configure resource diagnostic settings with a Log Analytics workspace destination, because diagnostic settings export selected resource log categories from the control plane. It does not demonstrate that the target case achieves transformed custom records are visible in the target Log Analytics table.
B:
B would instead validate the other design where a security operations firm needs to stream Azure resource logs to a third-party event processor. That evidence is consistent with set diagnostic settings to forward the selected logs to Azure Event Hubs, because diagnostic settings can stream supported resource logs to an event broker. It does not demonstrate that the target case achieves transformed custom records are visible in the target Log Analytics table.
C:
C would instead validate the other design where a managed-services team needs a standardized operational view of several virtual machines. That evidence is consistent with enable Azure Monitor VM insights for the supported virtual machines, because vM insights exposes guest performance and dependency observations. It does not demonstrate that the target case achieves transformed custom records are visible in the target Log Analytics table.
Question 21
An Azure architecture review has this requirement: An operations center needs an alert when a VM's CPU percentage stays high for ten minutes. Which design recommendation most directly meets it?
Create an Azure Monitor metric alert with an evaluation period.
Use Application Insights metrics and failure-performance views.
Centralize VM logs in an Azure Monitor Log Analytics workspace.
Enable Azure Monitor VM insights for the supported virtual machines.
Explanation
Correct Answer
A:
A is the best answer for the stated workload.

Microsoft AZ-305: Designing Azure Infrastructure Solutions
Microsoft exam AZ-305, Designing Microsoft Azure Infrastructure Solutions, is current as of October 1, 2026 and is part of the Azure Solutions Architect Expert path. Microsoft updated the English exam on April 17, 2026. The blueprint covers identity, governance and monitoring; data storage; business continuity; and infrastructure design.
The role is deliberately cross-functional. Azure solutions architects translate business requirements into cloud and hybrid designs while working with administrators, developers, security engineers, and data engineers. Candidates are expected to understand networking, virtualization, identity, security, disaster recovery, data platforms, governance, Azure administration, development, and DevOps well enough to understand how decisions in one area affect the rest.
Current certification planning pairs architecture with strong implementation experience. AZ-104 is the operational foundation, while the retired AZ-303 is historical context for the older architect path. AZ-305 should be studied as a design exam, not as a larger version of an administrator test.
Good architecture starts by turning requirements into design constraints
Every scenario contains signals about scale, availability, latency, security, compliance, budget, operational maturity, and recovery. The architect’s job is to identify which constraints are hard requirements and which are preferences. A service that is technically capable may still be wrong if it violates data residency, recovery objectives, team skills, or cost limits.
The Azure Well-Architected Framework helps organize this reasoning around reliability, security, cost optimization, operational excellence, and performance efficiency. Candidates should use these ideas to explain tradeoffs instead of searching for one universally best architecture.
Identity and governance designs establish the control model for the entire environment
Management groups, subscriptions, resource groups, policies, role assignments, privileged access, and Microsoft Entra architecture determine how teams operate at scale. The architect should define boundaries that support delegated ownership without losing central control. The Azure subscription hierarchy is therefore a design tool rather than administrative housekeeping.
Azure RBAC then implements least privilege within that hierarchy. Design questions often ask whether a requirement should be solved with an identity role, an Azure resource role, a policy, a management-group boundary, or a separate subscription. Understanding the purpose of each control prevents overengineering.
Storage design depends on data shape, access pattern, and failure tolerance
Architects choose among object storage, file services, relational databases, globally distributed databases, caches, and analytics platforms based on how data is produced and consumed. Important questions include consistency, transaction requirements, query model, latency, throughput, geography, durability, encryption, and retention.
Data decisions also influence compute placement and network design. A low-latency application may need services close to its data, while a globally distributed system may accept different consistency tradeoffs. The architect should design the data path as carefully as the application tier because data movement can become the dominant performance and cost factor.
Business continuity requires explicit recovery objectives
High availability and disaster recovery are related but not interchangeable. Availability zones can reduce the impact of a datacenter failure, while regional recovery addresses broader outages. Backups protect recoverable state but do not necessarily provide rapid service continuity. The architecture must be tied to recovery time and recovery point objectives.
Disaster-recovery planning also includes dependencies, runbooks, identity, DNS, network access, data consistency, and testing. An architect should be able to explain what fails over, in what order, how clients find the recovered service, and how normal operations resume.
Network design connects private resources, users, applications, and hybrid environments
Virtual networks, peering, hub-and-spoke patterns, private endpoints, load balancers, gateways, DNS, firewalls, ExpressRoute, and VPN connectivity are architectural building blocks. AZ-305 scenarios often require choosing a pattern that balances isolation, connectivity, routing control, resilience, and operational simplicity.
Specialists preparing for AZ-700 go deeper into these technologies, but an architect must understand their consequences. A centralized inspection model may simplify security governance while increasing route complexity; a highly segmented design may improve isolation but create operational overhead.
Compute architecture should minimize unnecessary infrastructure while preserving control
Virtual machines, scale sets, App Service, container platforms, serverless services, and managed application components offer different control boundaries. The architect should consider runtime requirements, scaling model, state, deployment frequency, team skills, portability, and operational burden before selecting a hosting model.
Managed services can remove patching and capacity tasks, but they may impose platform constraints. Conversely, infrastructure-heavy choices can support specialized needs while increasing maintenance. Good design does not automatically prefer the most abstract service; it chooses the simplest platform that satisfies the actual constraints.
Monitoring design should expose business-impacting failures, not just resource metrics
Architects need an observability plan that connects logs, metrics, traces, health signals, alerts, and dashboards to operational responsibilities. The Azure monitoring model is valuable because troubleshooting distributed systems requires correlation across multiple components.
A useful question is what evidence an on-call engineer will have when a user reports that the service is slow. If the design collects only CPU metrics, the team may miss dependency latency, application exceptions, network failures, or database waits. Observability should be designed alongside the architecture rather than added after launch.
Security architecture must be distributed across identity, network, compute, and data
No single firewall or identity policy secures an Azure solution. Architects should layer controls around privileged access, workload identity, network paths, secrets, data encryption, endpoint protection, vulnerability management, logging, and incident response. Zero Trust provides a useful model for verifying explicitly, using least privilege, and assuming breach.
The exam frequently rewards the design that reduces standing privilege and public exposure while keeping operations supportable. Security controls that cannot be maintained are fragile, so architecture should account for automation, ownership, monitoring, and emergency access as well as preventive policy.
AZ-305 preparation should be case-study driven
Build architecture diagrams from short requirement sets and annotate every important decision with a reason. Then challenge the design: increase traffic, reduce the recovery window, add a compliance constraint, require private access, or cut cost. This forces the candidate to understand which components are flexible and which are foundational.
Strong preparation does not memorize one reference architecture for every scenario. It develops a repeatable method: clarify requirements, identify constraints, choose a design, evaluate tradeoffs, and confirm operational consequences. That method is what makes AZ-305 an expert-level architecture exam rather than a product catalog test.
Migration architecture is another recurring theme because many Azure designs begin with an existing estate. Candidates should distinguish rehost, replatform, refactor, replace, and retire decisions, then consider dependency discovery and migration sequencing. A successful target architecture is not useful if the organization cannot move workloads into it safely. Network capacity, identity transition, data synchronization, and rollback planning are part of design.
Landing-zone thinking helps connect governance, connectivity, identity, and operations. Instead of designing each workload subscription from scratch, organizations can establish shared patterns for management groups, policy, connectivity, logging, security, and platform services. The architect should know when standardization reduces risk and when a workload needs a justified exception. This is especially important in large estates where consistency is an operational capability.
Cost optimization should be treated as architecture throughout the lifecycle. Service tiers, redundancy, data egress, idle capacity, reserved commitments, autoscaling, and operational labor all contribute to cost. The cheapest individual resource can produce an expensive system if it requires constant manual intervention or causes outages. A sound design evaluates total operating cost alongside technical requirements.
Performance design is similarly end-to-end. A faster database does not fix a network bottleneck, and adding more application instances does not fix a serialized dependency. Architects should identify the expected workload, latency budget, throughput targets, concurrency, and scaling boundaries, then determine which layer is likely to limit growth. Capacity planning should include both normal operation and degraded or failover states.
Architectural decisions should be documented with assumptions. If a design assumes that traffic stays within one region, that users authenticate through a specific tenant, or that a database can tolerate eventual consistency, those assumptions should be visible. Hidden assumptions become expensive failures when requirements change. Recording them also makes it easier to revisit the design during review without repeating the entire discovery process.
For exam preparation, practice defending two plausible designs instead of searching only for one answer. Explain what requirement would make option A preferable and what change would make option B stronger. This develops the tradeoff thinking that AZ-305 rewards and prevents candidates from turning Microsoft reference architectures into rigid templates that ignore scenario details.
Multi-region architecture should be justified by business impact. Adding a second region increases cost, deployment complexity, data-replication decisions, testing requirements, and operational procedures. The architect should know which failures the additional region addresses and how traffic, state, and identity behave during failover. “Use two regions” is not a complete resilience strategy.
Integration design also matters when workloads communicate through messaging, APIs, events, or shared data. Tight synchronous dependencies can make one slow service degrade an entire application. Queues and event-driven patterns can improve resilience but introduce eventual consistency and operational complexity. Architects should choose the interaction model based on timing, delivery guarantees, coupling, and failure behavior.
Finally, design reviews should include the team that will run the system. An architecture that requires skills, tooling, or twenty-four-hour response capability the organization does not possess may be unrealistic. Operational fit is a design constraint. AZ-305 preparation becomes stronger when candidates ask not only whether Azure can implement a pattern, but whether the stated organization can operate it safely.
Governance designs should also account for exceptions. Some workloads will legitimately require different regions, networking, privileged roles, or policy settings. A mature architecture defines how exceptions are requested, reviewed, time-bounded where possible, and monitored. This keeps standardization strong without forcing teams to bypass controls when a real business requirement falls outside the default pattern.
