Backlogged Input Events is a metric that shows the number of input events that are waiting to be processed by the Stream Analytics job1. This metric indicates the performance and health of the job, as well as the input data rate and latency. If the Backlogged Input Events metric is high or increasing, it means that the job is not able to keep up with the incoming events and some events are not processed in a timely manner2.
Output Events is a metric that shows the number of output events that are emitted by the Stream Analytics job1. This metric indicates the output data rate and throughput of the job. It does not show how many input events were not processed by the job.
Out-of-Order Events is a metric that shows the number of input events that arrive out of order based on their timestamp1. This metric indicates the quality and consistency of the input data source. It does not show how many input events were not processed by the job.
Late Input Events is a metric that shows the number of input events that arrive after the late arrival window has expired1. This metric indicates the timeliness and reliability of the input data source. It does not show how many input events were not processed by the job.

When collecting Windows Event Logs using the Azure Monitor Agent (AMA) with a Data Collection Rule (DCR), filtering is done at the source using XPath queries. XPath is specifically designed for querying XML- based event log entries, including filtering by Event ID, Event Level, and Event Source.
According to Azure Monitor documentation, Windows Event Log data sources require XPath expressions, not SQL or KQL. KQL is used after ingestion for querying data in Log Analytics, while XPath determines which events are collected in the first place.
Since the requirement is to collect only system events with Event ID 1001, the correct query type for the DCR data source is XPath.
Final Answer: C. XPath

In Azure, storage account keys are managed through Azure Role-Based Access Control (RBAC) permissions.
The ability to list and regenerate storage account keys requires access to specific management operations on the storage account resource, not encryption scopes.
According to Microsoft Azure Administrator documentation, the permissions required to list and regenerate storage account keys are:
* Microsoft.Storage/storageAccounts/listkeys/action
* Microsoft.Storage/storageAccounts/regeneratekey/action
Only specific built-in roles include these actions, such as:
* Owner
* Contributor
* Storage Account Contributor
However, the role mentioned in the question - Storage Account Encryption Scope Contributor - is designed for a different purpose.
From Microsoft's official documentation for Storage Account Encryption Scope Contributor:
"Grants permissions to manage encryption scopes within a storage account. Does not grant access to manage storage account keys or data." This means that assigning the Storage Account Encryption Scope Contributor role gives the user permissions to configure encryption scopes (for example, enabling or modifying encryption at the blob container level), but not to list or regenerate access keys.
Therefore, the solution fails to meet the requirement of enabling User1 to list and regenerate keys.
To achieve the goal, the correct role would be:
# Storage Account Contributor
This role explicitly allows managing all storage account properties, including key management.
Key Point (Microsoft Official Documentation Summary):
* Storage Account Encryption Scope Contributor # Manage encryption scopes only.
* Storage Account Contributor # Manage storage account settings, including listing and regenerating keys.

Explanation:

This question focuses on establishing a Remote Desktop (RDP) connection to a virtual machine (VM) through Azure Bastion using the native RDP client (mstsc.exe) from your local device.
Let's break down each step according to Microsoft's official Azure Bastion documentation.
Step 1: Upgrade Bastion1 to the Standard SKU
The Basic SKU of Azure Bastion supports only browser-based connections (via Azure Portal).
To use Native Client (RDP/SSH) support, you must use the Standard SKU.
The Standard SKU introduces advanced features like:
Native Client support (RDP/SSH via Azure CLI or PowerShell)
Kerberos Authentication
Custom port support
Scale-out for concurrent sessions.
# Therefore, before using the Azure CLI to initiate an RDP session, you must upgrade Bastion1 to the Standard SKU.
Step 2: From Bastion1, select Native Client Support
After upgrading to the Standard SKU, you must enable Native Client Support for Bastion1.
This option allows Azure Bastion to forward RDP/SSH connections using the native client (mstsc.exe) instead of the browser interface.
Once enabled, you can connect to the VM using your local Remote Desktop client over a secure Bastion connection.
# Enabling Native Client Support is mandatory before running Azure CLI commands to start the connection.
Step 3: From Azure CLI on Device1, run az network bastion rdp
Once Native Client Support is enabled, you can establish the RDP session directly using the Azure CLI command:
az network bastion rdp \
--name < BastionName > \
--resource-group < ResourceGroupName > \
--target-resource-id < VMResourceID >
This command launches the RDP client (mstsc.exe) locally on Device1 and securely tunnels the session through Bastion1 using Azure's internal backbone network-no public IP needed.
# This is the final step that establishes the RDP connection from your local Windows 11 device to the Azure VM.
Incorrect Options Explained:
# From Bastion1, enable Kerberos authentication: Optional feature, not required for standard RDP access.
# From VM1, enable Just-in-Time (JIT) access: Used for security hardening in Defender for Cloud, not required for Bastion RDP.
# On Device1, run mstsc.exe: You don't manually run mstsc.exe; the Azure CLI command automatically launches it.
# Final Verified Answer (in correct order):
Step
Action
1
Upgrade Bastion1 to the Standard SKU
2
From Bastion1, select Native Client Support
3
From Azure CLI on Device1, run az network bastion rdp
Microsoft Documentation Reference:
Microsoft Learn # Use Azure Bastion with a native client (RDP/SSH)
Microsoft Learn # Azure Bastion Standard SKU features overview
Microsoft Learn # Connect to a VM using Azure Bastion and Azure CLI
These documents confirm that Native Client support is only available in Azure Bastion Standard SKU, and the az network bastion rdp command is used to launch the RDP session via the native client.
