Quick Answer
The answer is Diagnostic settings. This is the correct configuration because Diagnostic settings on the Azure Firewall resource allow you to route platform logs and metrics to multiple destinations simultaneously, including a Log Analytics workspace for long-term analysis and a storage account for archival and compliance. On the AZ-104 exam, this question tests your understanding of how to manage Azure Firewall log data retention and compliance requirements, often appearing as a scenario where you must select the single resource-level configuration that supports both destinations. A common trap is confusing Diagnostic settings with Activity Log export or Azure Policy, but only Diagnostic settings on the firewall resource itself can stream logs directly to both a Log Analytics workspace and a storage account. Memory tip: think of Diagnostic settings as the "plumbing" that lets you send firewall logs to multiple sinks at once—just remember "Diagnostic settings for dual destinations."
This AZ-104 practice question tests your understanding of monitor and maintain azure resources. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You need to retain Azure Firewall logs for long-term analysis in a Log Analytics workspace and also archive them in a storage account for compliance. What should you configure on the Azure Firewall resource?
Diagnostic settings
This is the Azure-native mechanism for routing logs and metrics to monitoring destinations.
A resource lock
Why wrong: A lock protects resource operations but does not export logs.
An availability set
Why wrong: Availability sets are for VM resiliency.
A VNet peering connection
Why wrong: Peering connects networks and has nothing to do with log export.

Correct answer & explanation
Diagnostic settings
Diagnostic settings on the Azure Firewall resource allow you to stream platform logs and metrics to a Log Analytics workspace for long-term analysis and to a storage account for archival and compliance. This is the only configuration that simultaneously supports both destinations for the firewall's log data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

An availability set
Why it's wrong here

A VNet peering connection
Why it's wrong here
Peering connects networks and has nothing to do with log export.
Common exam traps
The trap here is that candidates may confuse resource locks or VNet peering with logging configurations, but only diagnostic settings provide the dual-destination log routing required for both analysis and compliance archival.
Detailed technical explanation
Diagnostic settings use Azure Monitor's data collection pipeline to route resource-level logs and metrics to multiple destinations simultaneously via a single configuration. For Azure Firewall, this includes the AzureFirewallApplicationRule, AzureFirewallNetworkRule, and AzureFirewallDnsProxy logs, which can be sent to a Log Analytics workspace for KQL-based analysis and to a storage account (blob or ADLS Gen2) for immutable, long-term compliance storage. The retention policy for the storage account is set independently, allowing indefinite archival.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
