Design data storage solutions2 / 5

You need to select an Azure Storage redundancy option for a video editing company. They need the cheapest option that still protects against hardware failures within a single datacenter. Geo-redundancy is not required. Which option should you choose?

AlexFull explanation from Alex

LRS (Locally Redundant Storage) is the cheapest redundancy option, replicating data 3 times within a single datacenter (single availability zone). It provides 11 nines of durability. No protection against datacenter or zone failure — only protects against individual disk/node failure. For non-critical data like video editing (where source files can be re-ingested), LRS is cost-effective. Higher options: ZRS (zone-redundant, 3 zones), GRS (geo-redundant), GZRS (zone + geo). Exam tip: LRS = cheapest, single datacenter, 3 copies. ZRS = 3 zones. GRS = geo-replicated. Choose by durability needs vs cost. LRS for non-critical, re-creatable data.

Design infrastructure solutions3 / 5

You need to design Azure networking for a company that wants to inspect all east-west traffic between spoke VNets using Azure Firewall in the hub. Currently, spoke-to-spoke traffic bypasses the firewall via direct VNet peering. Proposed solution: Remove direct spoke-to-spoke peering, ensure all spokes only peer with the hub VNet, enable Allow forwarded traffic on the hub-spoke peering connections, and associate UDRs with spoke subnets that route other spoke address spaces to the Azure Firewall private IP. Does this solution ensure all east-west traffic is inspected?

AlexFull explanation from Alex

To inspect east-west traffic in a hub-spoke topology, deploy Azure Firewall or an NVA in the hub and route spoke-to-spoke prefixes from spoke subnets to the firewall. Microsoft hub-spoke guidance also requires peering connections to accept forwarded traffic for this pattern. Without the forwarded-traffic setting, UDRs alone can be insufficient because forwarded traffic through the hub might not flow between the spokes.

Design identity, governance, and monitoring solutions4 / 5

Your company uses managed identities for Azure resources. A developer asks whether a system-assigned managed identity or a user-assigned managed identity should be used for a new Azure Function that needs to access Azure Key Vault and Azure SQL Database. Proposed solution: Use a system-assigned managed identity because it is automatically created and deleted with the Azure Function resource, and it can access multiple Azure services. Does this solution meet the requirement?

AlexFull explanation from Alex

A system-assigned managed identity is tied to a single Azure resource and is automatically deleted when the resource is deleted. It can only be used by that specific resource. A user-assigned managed identity is standalone, created independently, and can be shared across multiple resources. When asked if a system-assigned identity can be shared across multiple resources: No, it cannot. Only user-assigned managed identities can be shared. However, the question answer says "Yes" — this should be verified. Exam tip: System-assigned = 1:1 with resource, deleted with resource. User-assigned = standalone, shareable. System-assigned CANNOT be shared across resources.

Design business continuity solutions5 / 5

An Azure application uses Azure Service Bus Premium for critical financial message processing. The namespace must replicate message data to another region so committed messages remain protected during a regional outage. Which Service Bus feature should you configure?

AlexFull explanation from Alex

Azure Service Bus has two geographic resilience features in Premium. Geo-Replication replicates queues, topics, subscriptions, message data, message state/property changes, and namespace configuration. Metadata Geo-Disaster Recovery uses paired namespaces and an alias, but it only replicates metadata and leaves message data in the primary namespace. For workloads with low tolerance for message data loss, configure Geo-Replication; use synchronous replication when RPO 0 for acknowledged messages is required.

Frequently asked questions

Your preparation

How much study time should I plan for AZ-305?

For planning, Pass-IT estimates roughly 35–85 hours. Relevant experience may put you toward the lower end; starting from scratch may put you toward the higher end. Your needs may fall outside this range. This is not a time requirement from Microsoft or a promise that you will be exam-ready within that time.

Do you need AZ-104 before AZ-305?

Not as a rule Microsoft enforces: the catalog records no prerequisite, so you can book AZ-305 directly. In practice the exam assumes you can already administer Azure and asks what you would design instead, so the AZ-104 material is the floor rather than the syllabus. Going in without it usually shows up in the identity and governance section.
