Free Access Microsoft AZ-104 New Release

To meet the technical requirement — “Use TLS for WebApp1” — the web app must be configured with a certificate that is compatible with Azure App Service for HTTPS/TLS binding.

According to the Microsoft Azure Administrator documentation on App Service Certificates and Key Vault integration, the following key points determine which certificates can be used:

Supported Certificate Format:Azure App Service supports importing certificates in PFX (PKCS #12) format, which includes both the public and private keys necessary for TLS/SSL binding.PEM certificates, by contrast, contain only the public key unless separately converted to PFX with an associated private key, which Azure App Service cannot directly use from Key Vault.

Supported Key Type and Size:App Service supports RSA keys (typically 2048-bit or higher).Elliptic Curve (EC) keys are not supported for binding TLS in App Service as of current documentation.

Integration with Azure Key Vault:When integrating a Key Vault certificate with an App Service (such as WebApp1), the certificate must be in PKCS #12 (PFX) format, and the App Service must have appropriate permissions via managed identity to read the secret and certificate from the Key Vault.

From the Vault1 data provided in your scenario:

Analysis:

Cert1 and Cert2 are PKCS #12 certificates, so both contain the private key required for TLS.

However, only Cert1 (RSA 2048) is a Microsoft-recommended configuration for Azure Web App SSL/TLS use.

Cert2 has a 4096-bit RSA key. Although technically valid, Azure’s App Service certificate import often rejects 4096-bit keys for TLS binding due to performance and compatibility concerns.

Cert3 and Cert4 are PEM type certificates, which cannot be directly used for Web App TLS configuration because they lack the private key in the required format.

Therefore, according to the Azure Administrator Exam Study Guide and Microsoft official documentation, the only valid certificate that meets the requirements is:

✅ Cert1 only

Final Verified Answer: ✅ A. Cert1 only

The planned change specifies that you must configure a Data Collection Rule (DCR) to collect only system events with Event ID 4648 from VM2 and VM4.

A Data Collection Rule (DCR) in Azure Monitor defines how data is collected from resources, filtered, and sent to destinations like Log Analytics workspaces. To define or query this data within Azure Monitor Logs or Log Analytics, you use Kusto Query Language (KQL).

From the Microsoft Learn: Azure Monitor Logs Documentation:

“Log queries in Azure Monitor are written in Kusto Query Language (KQL), the same query language used by Azure Data Explorer.”

“KQL is optimized for querying large datasets, filtering by event IDs, sources, and event types.”

Other options:

WQL (WMI Query Language) – used for on-prem Windows event querying, not for Azure DCR.

T-SQL (Transact-SQL) – used for Azure SQL Database queries, not for monitoring data.

XPath – used in Event Viewer or XML-based event filtering, not within Azure Monitor DCR configuration.

Therefore, when you configure DCR1 to collect system events (Event ID 4648) from the specified VMs, the Kusto Query Language (KQL) is the correct and verified method to filter and process these events.

Example of a valid KQL expression for this requirement:

SecurityEvent

| where EventID == 4648

| where Computer in ( " VM2 " , " VM4 " )

This aligns with the Azure Monitor and Log Analytics query methodology covered in AZ-104 official exam guide (Implement and manage monitoring).
