Question 2

A build pipeline starts a containerized data-processing job every evening. Each run finishes in under 20 minutes, does not need persistent servers, and never receives inbound traffic. Which compute service best fits this workload?

Accepted Answer

Azure Container Instances. Azure Container Instances (ACI) is the best fit because it allows you to run a containerized job directly in Azure without provisioning or managing any underlying infrastructure. The workload is short-lived (under 20 minutes), requires no persistent servers, and has no inbound traffic, which aligns perfectly with ACI's pay-per-second billing and ability to start containers on demand from a build pipeline.

Question 3

A Linux VM deployed from a custom image shows only a black screen after reboot, and SSH never becomes available. The administrator needs to inspect the startup process without logging into the OS. Which two Azure features should be used? Select two.

Accepted Answer

Boot diagnostics. Boot diagnostics captures serial console output and screenshots of the VM during boot, allowing you to see kernel panics, driver failures, or bootloader errors even when the OS is unresponsive. Azure Serial Console provides a text-based console connection to the VM at the hypervisor layer, enabling interactive troubleshooting of the boot process (e.g., GRUB recovery, initramfs issues) without requiring network connectivity or SSH.

Question 4

A customer-facing application runs on two Azure VMs. The business wants the application to stay available even if one datacenter in the Azure region has an outage. Which availability option should the administrator use?

Accepted Answer

Availability zones. Availability Zones are physically separate datacenters within an Azure region, each with independent power, cooling, and networking. By deploying the two VMs into different zones, the application remains available if one entire datacenter fails, meeting the requirement for datacenter-level fault tolerance.

Answer

Availability set

Answer

Proximity placement group

Answer

Azure Load Balancer

Question 5

A stateless customer portal runs on Azure VMs and must keep serving traffic if an entire datacenter in the region fails. The operations team also wants the portal to add and remove instances automatically during daily spikes without managing a Kubernetes cluster. Which two Azure compute capabilities should the administrator configure? Select two.

Accepted Answer

Deploy the portal instances across availability zones.. Availability zones protect against a full datacenter failure by distributing VM instances across physically separate datacenters within a region. This ensures that if one datacenter goes down, the portal continues serving traffic from the other zones. Combined with a load balancer, this provides high availability for stateless workloads.

Answer

Place the VMs in an availability set within a single datacenter.

Answer

Create a proximity placement group for the portal VMs.

Answer

Use a single larger VM with premium managed disks.

Question 6

A Windows VM must install a monitoring agent, run a bootstrap script during provisioning, and download a configuration file from an Azure resource without storing any credentials in the script or on disk. Which two Azure compute features should the administrator use? Select two.

Accepted Answer

Use a Custom Script Extension to run the bootstrap actions after provisioning.. The Custom Script Extension (CSE) is the correct Azure feature to run a bootstrap script after provisioning because it executes a script on the VM during or after deployment, enabling installation of the monitoring agent and other configuration tasks. It is the standard method for post-deployment automation on Azure VMs, and it can reference a script stored in Azure Storage or a public URL without embedding credentials.

Answer

Enable boot diagnostics and review the serial console output.

Answer

Attach a read-only managed disk to store the configuration file.

Answer

Use an availability set to keep the bootstrap script highly available.

Question 7

A Windows VM must run a bootstrap script during provisioning to install a monitoring agent and write configuration files. The administrator does not want to log in interactively, and the script must be runnable again after the VM is rebuilt. Which two Azure compute components should be used? Select two.

Accepted Answer

Azure VM Agent. The Azure VM Agent (A) is required because it enables the VM to run extensions, including the Custom Script Extension. The Custom Script Extension (B) is the correct mechanism to execute the bootstrap script during provisioning without interactive login, and it can be reapplied to a rebuilt VM by redeploying the same ARM template or CLI command.

Answer

Boot diagnostics

Answer

Availability zone

Answer

Ephemeral OS disk

Question 8

A Windows VM must install an agent and copy a configuration file automatically after provisioning. The administrator wants Azure to run the setup step without logging into the VM manually. Which feature should be used?

Accepted Answer

VM extension. VM extensions are the correct Azure feature to automatically install agents and apply configurations during or after provisioning without manual login. The Custom Script Extension (CSE) specifically can execute a PowerShell or Bash script to install the agent and copy the configuration file, running as a post-deployment task via Azure Resource Manager (ARM) templates, Azure CLI, or PowerShell.

Availability set

Question 9

A reporting server will run an in-memory analytics workload that needs 8 vCPUs and 64 GiB RAM. CPU usage is expected to stay moderate, but the application benefits most from memory capacity. Which VM family should the administrator choose as the starting point?

Accepted Answer

E-series. The E-series (memory-optimized) VM family is designed for in-memory analytics workloads that require high memory-to-CPU ratios. With 8 vCPUs and 64 GiB RAM, the workload demands 8 GiB per vCPU, which aligns with E-series specifications (typically 8–16 GiB per vCPU). D-series offers a balanced ratio (4 GiB per vCPU) and would not provide sufficient memory capacity for this workload.

Answer

B-series

Answer

D-series

Answer

F-series

Question 10

A stateless web service runs on identical VMs and must keep serving traffic if Microsoft takes one datacenter out of service in the region. The load must also scale out automatically during peak hours, and instances should be spread across independent zone boundaries. Which two configurations should the administrator use? Select two.

Accepted Answer

Virtual machine scale set. A is correct because Virtual Machine Scale Sets (VMSS) provide built-in autoscaling capabilities that automatically adjust the number of VM instances based on demand (e.g., CPU or memory metrics), ensuring the web service scales out during peak hours. Additionally, VMSS supports spreading instances across availability zones, which protects against a single datacenter failure by distributing VMs across independent zone boundaries within a region.

Proximity placement group

Answer

Dedicated host

Question 11

After applying a custom image, a VM restarts to a black screen and never reaches the sign-in prompt. The administrator wants the fastest way to inspect the boot process without connecting to the guest OS. What should be used?

Accepted Answer

Boot diagnostics. Boot diagnostics captures serial console output and screenshots of the VM during the boot process, allowing you to inspect boot failures like a black screen without needing to connect to the guest OS. This is the fastest method because it provides immediate, out-of-band access to boot logs and visual state, even when the OS is unresponsive.

Question 12

A Linux VM restarts after a configuration change and now stops before the sign-in prompt. The administrator cannot use SSH. Which Azure feature should be checked first to inspect the startup process?

Accepted Answer

Boot diagnostics. Boot diagnostics captures serial console output and screenshots of the VM, allowing you to view kernel messages, boot logs, and the exact point where the startup process halts. Since SSH is unavailable and the VM stops before the sign-in prompt, this is the first Azure feature to check for troubleshooting the boot sequence.

Question 13

A build pipeline needs to run a Linux container for about 15 minutes whenever a request arrives. The job never needs inbound traffic, clustering, or persistent node management. A second workload is a public web app that needs built-in TLS, deployment slots, and autoscale. Which two Azure compute services should the administrator choose? Select two.

Accepted Answer

Azure Container Instances. Azure Container Instances (ACI) is the correct choice for the first workload because it allows you to run a Linux container on demand without managing any underlying infrastructure, and it supports a 15-minute execution time perfectly with its per-second billing and no requirement for persistent nodes or inbound traffic. Azure App Service is correct for the second workload because it natively provides built-in TLS/SSL termination, deployment slots for staging and swapping, and autoscale capabilities out of the box, making it ideal for a public web app.
