Designing Microsoft Azure Infrastructure Solutions AZ-305 Practice Test 7
Question 60
A change advisory board requests objective evidence for this design target: An organization wants to block production engineers from deleting protected Azure resources accidentally. Which verification is most relevant?
authorized blob reads succeed and storage-account configuration changes are rejected.
operations in the designated resource group succeed while equivalent actions elsewhere are denied.
the SaaS account is created and later disabled following source-directory changes.
a delete request is refused while normal authorized nondelete operations remain available.
Explanation
Correct Answer
D:
D is the best answer for the stated workload. Apply a CanNotDelete management lock to the selected scope is appropriate because resource locks deny deletion operations even when Azure RBAC permits management. The observable acceptance condition is that a delete request is refused while normal authorized nondelete operations remain available. 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 storage application must read blobs without being able to change storage account settings. That evidence is consistent with grant a data-plane Storage Blob Data Reader role at an appropriate scope, because azure data-plane RBAC roles are distinct from management-plane access. It does not demonstrate that the target case achieves a delete request is refused while normal authorized nondelete operations remain available.
B:
B would instead validate the other design where a department should manage only one Azure resource group without subscription-wide permissions. That evidence is consistent with assign an appropriate Azure RBAC role at resource-group scope, because rBAC scopes limit management permissions to the target resources. It does not demonstrate that the target case achieves a delete request is refused while normal authorized nondelete operations remain available.
C:
C would instead validate the other design where a SaaS application should receive user accounts and removal events automatically from the enterprise directory. That evidence is consistent with configure Microsoft Entra automatic application provisioning with SCIM where supported, because lifecycle provisioning propagates identity creations, updates, and deprovisioning. It does not demonstrate that the target case achieves a delete request is refused while normal authorized nondelete operations remain available.
Question 61
An Azure architecture review has this requirement: A legacy LDAP application moved into Azure still needs domain join and Kerberos without operating domain controllers. Which design recommendation most directly meets it?
Use Microsoft Entra Domain Services for supported managed domain functionality.
Maintain supported hybrid identity synchronization and AD DS group-based permissions.
Assign an appropriate Azure RBAC role at resource-group scope.
Preserve AD DS authentication and connect devices through the approved hybrid network path.
Explanation
Correct Answer
A:
A is the best answer for the stated workload. Use Microsoft Entra Domain Services for supported managed domain functionality is appropriate because the managed domain supplies LDAP, Kerberos, and domain join for compatible workloads. The observable acceptance condition is that the application authenticates with Kerberos to the managed domain. Selecting a design alone is insufficient without validating this behavior.
Incorrect Answers
B:
“Maintain supported hybrid identity synchronization and AD DS group-based permissions” relies on this Azure capability: local file authorization remains governed by AD DS and NTFS while identity is synchronized. This workload involves A legacy LDAP application moved into Azure still needs domain join and Kerberos without operating domain controllers. The decisive Azure design mechanism is: the managed domain supplies LDAP, Kerberos, and domain join for compatible workloads. Thus “Use Microsoft Entra Domain Services for supported managed domain functionality” is the applicable architecture choice.

Question 62
The implementation team has deployed a design to address this requirement: A legacy LDAP application moved into Azure still needs domain join and Kerberos without operating domain controllers. Which observed result best demonstrates that the intended design works?
a synchronized employee can access only the file shares permitted by its AD groups.
the application authenticates with Kerberos to the managed domain.
authorized domain users can obtain a ticket and access the on-premises application.
operations in the designated resource group succeed while equivalent actions elsewhere are denied.

Incorrect Answers
A:
A would instead validate the other design where a company keeps on-premises file shares with NTFS ACLs and needs Azure cloud identities linked to AD accounts. That evidence is consistent with maintain supported hybrid identity synchronization and AD DS group-based permissions, because local file authorization remains governed by AD DS and NTFS while identity is synchronized. It does not demonstrate that the target case achieves the application authenticates with Kerberos to the managed domain.
C:
C would instead validate the other design where a business wants staff on managed Windows devices to authenticate to an on-premises application using established domain access. That evidence is consistent with preserve AD DS authentication and connect devices through the approved hybrid network path, because network reachability and domain trust are required for conventional on-premises Kerberos resources. It does not demonstrate that the target case achieves the application authenticates with Kerberos to the managed domain.

Question 63
A solution architect receives the following workload requirement: A company keeps on-premises file shares with NTFS ACLs and needs Azure cloud identities linked to AD accounts. Which option should the architect recommend?
Preserve AD DS authentication and connect devices through the approved hybrid network path.
Use versioned Key Vault secret retrieval with a governed rotation strategy.
Maintain supported hybrid identity synchronization and AD DS group-based permissions.
Integrate Microsoft Entra application proxy for a supported internal web application.

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.
