Exam AZ-104 topic 4 question 47 discussion

Correct Answer: B The Linux diagnostic extension helps a user monitor the health of a Linux VM running on Microsoft Azure. It has the following collection and capabilities: - Metrics - Syslog - Files A: Azure HDInsight is a managed, full-spectrum, open-source analytics service in the cloud for enterprises. You can use open-source frameworks such as Hadoop, Apache Spark, Apache Hive, LLAP, Apache Kafka, Apache Storm, R, and more. C: Azure Performance Diagnostics VM Extension is used for Windows VM only. D: Azure Analysis Services is a fully managed platform as a service (PaaS) that provides enterprise-grade data models in the cloud.

Not correct. Answer is B. it is linux server accordingly Linux Diagnostic Extension should be used which download the Diagnostic Extension (LAD) agent on Linux server.

B is corerct

B is right

To monitor the metrics and logs of a Linux virtual machine in Azure, you can use the Linux Diagnostic Extension (LAD) 3.0. Therefore, the correct answer is: B. Linux Diagnostic Extension (LAD) 3.0 LAD is a solution provided by Microsoft to collect diagnostic data, logs, and metrics from Linux virtual machines running in Azure. LAD can be used to monitor key performance indicators (KPIs) such as CPU, memory, and disk usage, as well as collect system logs and custom logs. Option A, Azure HDInsight, is a cloud-based service that provides Apache Hadoop and Spark clusters for big data processing. Option C, the AzurePerformanceDiagnostics extension, is not a valid Azure service or feature. Option D, Azure Analysis Services, is a PaaS offering that provides enterprise-grade analytics and BI services in the cloud. It is not designed for monitoring Linux virtual machines.

Correct Answer is B

Answer B: Here's why... Some of the feature in "the AzurePerformanceDiagnostics extension" do not work for Linux VMs: (https://docs.microsoft.com/en-us/troubleshoot/azure/virtual-machines/performance-diagnostics#select-an-analysis-scenario-to-run) Where as the "Linux Diagnostic Extension (LAD) 3.0" doc mentions the question's two requirements Metrics and Logs in the first two sentances of the intoduction of this article: https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/diagnostics-linux-v3

I Luv Honey Because it is B For sure B the Linux diagnostic extension helps a user monitor the health of a Linux VM running on Microsoft Azure, In summary is used to monitor metrics and logs of Linux VM. It has the following collection and capabilities: New in LAD 4.0 This extension works with both Azure deployment models (Azure Resource Manager and classic). You can enable this extension for your VM and virtual machine scale set by using the Azure PowerShell cmdlets, Azure CLI scripts, Azure Resource Manager templates (ARM templates), or the Azure portal.

C. the AzurePerformanceDiagnostics extension

Answer is correct, supports both Linux and Windows https://docs.microsoft.com/en-us/troubleshoot/azure/virtual-machines/performance-diagnostics

https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/diagnostics-linux?tabs=azcli

Use the Linux diagnostic extension 4.0 to monitor metrics and logs: https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/diagnostics-linux?tabs=azcli Azure Performance Diagnostics VM Extension is for Windows: https://docs.microsoft.com/en-us/troubleshoot/azure/virtual-machines/performance-diagnostics-vm-extension

It is clearly B

Important For information about version 3.x, see Use the Linux diagnostic extension 3.0 to monitor metrics and logs. For information about version 2.3 and earlier, see Monitor the performance and diagnostic data of a Linux VM.

B The Linux diagnostic extension helps a user monitor the health of a Linux VM that runs on Microsoft Azure

Answer is B but question is outdated : https://docs.microsoft.com/en-us/azure/azure-monitor/agents/agents-overview Azure Monitor recently launched a new agent, the Azure Monitor agent, that provides all capabilities necessary to collect guest operating system monitoring data. While there are multiple legacy agents that exist due to the consolidation of Azure Monitor and Log Analytics, each with their unique capabilities with some overlap, we recommend that you use the new agent that aims to consolidate features from all existing agents, and provide additional benefits.
