Q1AZ-305
Show answer
Correct answer: A. In Microsoft Entra ID, create an access review for Application1.

The requirement is to send a monthly review request to managers and automatically revoke rights if they are not verified.
With Microsoft Entra ID (formerly Azure AD) access reviews, you can set up recurring reviews targeting enterprise apps or role assignments, send a notification (email) at the start, and remove access for unapproved users through automatic application of results.
Because operation is completed mainly through configuration, it can minimize implementation work on the developer side.

Correct answer: A. Azure AD Application Proxy, E. An Azure AD enterprise application

To securely publish the on-premises internal web app without using a VPN while also achieving SSO, you use Microsoft Entra application proxy to relay communication with a cloud-side service and an on-premises-side connector.
Furthermore, you register WebApp1 as an enterprise application in Entra ID and configure SSO (for Integrated Windows Authentication, use Kerberos constrained delegation and the like as needed).
PIM, Arc, or Application Gateway alone cannot meet the requirement to “provide SSO without a VPN.”

Correct answer: A. Azure Log Analytics

Within a subscription, “when, who, and what was deployed/created” can be tracked in the activity log (platform log), but because the retention period is limited, it is not sufficient for monthly reporting purposes.
Therefore, it is appropriate to use diagnostic settings to send the activity log to Azure Monitor Logs (backed by a Log Analytics workspace) to accumulate it, and aggregate deployment (Microsoft.Resources/deployments/write) and resource creation events with KQL.
Application Insights is for app observability, and Arc and Analysis Services serve different purposes.

Show answer
Correct answer: C. Create an access review.

The requirements are “quarterly periodic evaluation,” “self-attestation by all members including guests,” and “automatic removal of those not needed or non-responders.”
Microsoft Entra ID (formerly Azure AD) access reviews can set up a recurring review every 3 months targeting group membership and designate the members themselves as reviewers.
Furthermore, through automatic application of results, you can automatically remove users who deny (not needed) or do not respond from the group, minimizing operational overhead.

Correct answer: A. Azure Front Door

The requirement is to meet “global (multi-region) failover,” “WAF,” “cookie-based session persistence,” and “URL (path)-based routing” through a single entry point.
Azure Front Door, as a global L7 (HTTP/HTTPS) load balancer, can provide WAF integration, cookie-based session affinity, and URL path-based routing.
Because Traffic Manager is DNS-based and does not have WAF or cookie/URL routing capabilities, it cannot meet the conditions of this question on its own.

Q6AZ-305
Number of Virtual WAN hubs

Virtual WAN SKU

Show answer
Correct answer: 3 / Standard

To minimize latency, placing a virtual hub in each of the three regions where you want to provide connectivity (Southeast Asia, North Europe, and South Africa) is the minimal configuration, which comes to three hubs.
Also, a Basic Virtual WAN/hub is limited to the site-to-site VPN feature and does not support ExpressRoute.
Because this requirement includes both ExpressRoute and site-to-site VPN, the Standard SKU is required.

Provides protection against common vulnerabilities identified by OWASP (Open Web Application Security Project).

API Management
Show answer
Correct answer: Front Door → Provides protection against common vulnerabilities identified by OWASP (Open Web Application Security Project). / API Management → Validates JSON Web Tokens (JWT) issued by Azure AD B2C.

Azure Front Door integrates with WAF and can provide protection at the edge against common attacks and vulnerabilities based on rule sets such as the OWASP ruleset (CRS).
On the other hand, to reliably validate tokens issued by Azure AD B2C (now Microsoft Entra External ID) on the API gateway side, it is appropriate to validate the JWT with the validate-jwt policy in API Management.
Therefore, assign OWASP protection to Front Door and JWT validation to API Management.

Q8AZ-305
Permission to assign on KV1

Permission to assign on KV2

Show answer
Correct answer: List / Create

Because App1 already has the Get permission on KV1, to replicate all secrets it additionally needs the List permission to enumerate which secrets exist.
On the KV2 side, because it must newly create (set) and store the retrieved secrets, you grant the Create permission, which corresponds to creation.
This allows App1 to copy from KV1 to KV2 through the flow of list → get → create.

Show answer
Correct answer: A. Azure Cosmos DB for NoSQL

The requirements are “querying with SQL,” “simultaneous writes across multiple regions (multi-master),” and “guaranteed low-latency reads.”
Azure Cosmos DB for NoSQL provides a SQL-compatible query language and can be made active-active by enabling multi-region writes.
Furthermore, SLAs such as availability and P99 latency are explicitly stated, so you can aim for low latency globally.
Azure SQL active geo-replication is centered on read-only secondaries and does not meet the multi-master requirement.

Show answer
Correct answer: D. Azure Data Factory

To run SSIS packages on Azure, it is appropriate to use the Azure-SSIS Integration Runtime of Azure Data Factory.
The Azure-SSIS Integration Runtime is a managed execution environment that can run SSIS packages as-is on Azure.
Therefore, existing SSIS workloads can be migrated easily without major rework, and it can also host packages whose destination is Azure SQL Database.
SSMA and Data Migration Assistant are mainly tools that assist with database migration and are not suited to hosting SSIS packages.
