Microsoft Microsoft Certifications AZ-104 Questions & Answers

• Question 131:

  You have an Azure subscription that contains an Azure virtual machine named VM1. VM1 runs a financial reporting app named App1 that does not support multiple active instances.

  At the end of each month, CPU usage for VM1 peaks when App1 runs.

  You need to create a scheduled runbook to increase the processor performance of VM1 at the end of each month.

  What task should you include in the runbook?

  A. Add the Azure Performance Diagnostics agent to VM1.

  B. Modify the VM size property of VM1.

  C. Add VM1 to a scale set.

  D. Increase the vCPU quota for the subscription.

  E. Add a Desired State Configuration (DSC) extension to VM1.

  Correct Answer: B

  If you have a CPU/performance issue then the solution is to scale up (increase VM size) or to scale out (scale set) given that the App does not support multiple instances then scale up is the obvious choice. Reference: https://docs.microsoft.com/en-us/azure/virtual-machines/windows/resize-vm

• Question 132:

  You have an Azure subscription named Subscription1.

  You deploy a Linux virtual machine named VM1 to Subscription1.

  You need to monitor the metrics and the logs of VM1.

  What should you use?

  A. Linux Diagnostic Extension (LAD) 3.0

  B. Azure Analysis Services

  C. the AzurePerformanceDiagnostics extension

  D. Azure HDInsight

  Correct Answer: A

  You can use extensions to configure diagnostics on your VMs to collect additional metric data. The basic host metrics are available, but to see more granular and VM-specific metrics, you need to install the Azure diagnostics extension on the

  VM. The Azure diagnostics extension allows additional monitoring and diagnostics data to be retrieved from the VM.

• Question 135:

  You have an Azure subscription that contains an Azure Storage account.

  You plan to create an Azure container instance named container1 that will use a Docker image namedImage1. Image1 contains a Microsoft SQL Server instance that requires persistent storage.

  You need to configure a storage service for Container1.

  What should you use?

  A. Azure Files

  B. Azure Blob storage

  C. Azure Queue storage

  D. Azure Table storage

  Correct Answer: A

  Microsoft have Docker Volume Plugin for Azure file storage which provides exactly this and it is used for Azure file shares.

  Azure File Storage volume plugin is not limited to ease of container migration. It also allows a file share to be shared among multiple containers (even though they are on different hosts) to collaborate on workloads, share configuration or

  secrets of an application running on multiple hosts. Another use case is uploading metrics and diagnostics data such as logs from applications to a file share for further processing.

• Question 136:

  You have an app named App1 that runs on two Azure virtual machines named VM1 and VM2.

  You plan to implement an Azure Availability Set for App1. The solution must ensure that App1 is available during planned maintenance of the hardware hosting VM1 and VM2.

  What should you include in the Availability Set?

  A. one update domain

  B. two fault domains

  C. one fault domain

  D. two update domains

  Correct Answer: D

  Microsoft updates, which Microsoft refers to as planned maintenance events, sometimes require that VMs be rebooted to complete the update. To reduce the impact on VMs, the Azure fabric is divided into update domains to ensure that not

  all VMs are rebooted at the same time.

  Incorrect Answers:

  A: An update domain is a group of VMs and underlying physical hardware that can be rebooted at the same time.

  B, C: A fault domain shares common storage as well as a common power source and network switch. It is used to protect against unplanned system failure.

  D. az storage blob copy start-batch D:\Folder1 https://contosodata.blob.core.windows.net/public

  Correct Answer: C

  The azcopy copy command copies a directory (and all of the files in that directory) to a blob container. The result is a directory in the container by the same name. Incorrect Answers:

  B: The azcopy sync command replicates the source location to the destination location. However, the file is skipped if the last modified time in the destination is more recent.

  D: The az storage blob copy start-batch command copies multiple blobs to a blob container.
