Question 1

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?

Choose an answer to begin — your selection is scored in the full session.

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.

F-series

Question 2

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 3

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 4

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 5

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.

Question 6

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?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Memory-optimized VM family. Memory-optimized VM families (e.g., Azure E-series) are designed for workloads that require a high memory-to-vCPU ratio, such as in-memory analytics applications. The requirement of 64 GiB of RAM for 8 vCPUs (8:1 ratio) aligns with the memory-optimized profile, which offers up to 8 GiB per vCPU or more, ensuring the application's data fits entirely in RAM for low-latency processing.

Answer

Burstable VM family

Answer

Compute-optimized VM family

Answer

Storage-optimized VM family

Question 7

A reporting application will run on a single Azure VM and needs 8 vCPUs, 64 GiB of RAM, and a temporary local disk for cache. The team wants a size that satisfies the requirement without oversizing memory or paying for an unnecessarily large specialty series. Which two VM sizes meet the requirement best? Select two.

Accepted Answer

E8as_v5. The E8as_v5 is correct because it provides 8 vCPUs and 64 GiB of RAM, matching the requirement exactly, and includes a temporary local disk (SSD) for cache. It belongs to the memory-optimized Esv5 series, which is designed for memory-intensive workloads without oversizing, and the 'as' variant includes local temporary storage.

Answer

D8as_v5

Answer

F8s_v2

Answer

M8ms

Question 8

An application uses two Azure VMs in the same datacenter and must continue through planned maintenance and a single hardware host failure. The administrator does not need separate datacenter protection. Which option should be used?

Accepted Answer

Availability set. An availability set distributes VMs across multiple fault domains (hardware hosts) and update domains within a single Azure datacenter. This ensures that during planned maintenance (update domains) or a single hardware host failure (fault domains), at least one VM remains available. Since the requirement does not include separate datacenter protection, an availability set is the correct choice.

Answer

Availability zones

Answer

Proximity placement group

Answer

Virtual machine scale set

Question 9

A company is deploying two Linux application VMs in Azure for a production workload. The region supports availability zones, and the business requires the workload to stay online if an entire datacenter in the region becomes unavailable. Which deployment choice best meets this requirement?

Accepted Answer

Deploy the VMs across two availability zones in the same region.. Availability zones are physically separate datacenters within an Azure region, each with independent power, cooling, and networking. Deploying the two Linux VMs across two different zones ensures that if an entire datacenter fails, the VM in the other zone remains online, meeting the requirement for resilience against a full datacenter outage.

Answer

Place both VMs in the same availability set so Azure separates them across update domains.

Answer

Use a single larger VM size with premium SSD storage for better uptime.

Answer

Deploy the VMs in the same resource group and enable auto-shutdown.

Question 10

A container group runs a one-time import job in Azure Container Instances. After the job finishes successfully, it should not restart. Which restart policy should you choose?

Accepted Answer

Never. The 'Never' restart policy ensures that the container group does not restart after the job completes, which is ideal for a one-time import job that should run exactly once. Azure Container Instances supports three restart policies: Always, OnFailure, and Never. For a job that must not restart after successful completion, 'Never' is the correct choice because it prevents any automatic restart regardless of the exit code.

Answer

Always

Answer

OnFailure

Question 11

A business wants a line-of-business VM workload to keep running if one Azure datacenter in the region goes offline. Which two deployment choices should the administrator use? Select two.

Accepted Answer

Deploy the VMs in different availability zones.. Deploying VMs across different availability zones protects against a single datacenter failure. Each availability zone is a physically separate datacenter within an Azure region, with independent power, cooling, and networking. If one zone goes offline, the VM in the other zone remains operational, ensuring business continuity for the line-of-business workload.

Answer

Place the VMs in the same availability set.

Answer

Use a proximity placement group for the VMs.

Answer

Use a snapshot of the operating system disk.

Question 12

A line-of-business app runs on two VMs in an Azure region that supports availability zones. The business wants protection from a datacenter failure and wants the VMs placed in different physical locations within the region. Which deployment choice should be used?

Accepted Answer

Two availability zones with one VM in each zone. Availability zones are physically separate datacenters within an Azure region, each with independent power, cooling, and networking. Placing one VM in each of two zones ensures that if one datacenter fails, the other VM remains available. This directly meets the requirement for protection from a datacenter failure with VMs in different physical locations.

Answer

An availability set with two fault domains

Answer

A proximity placement group for both VMs

Answer

A single larger VM size with Premium SSD

Question 13

Based on the exhibit, what should the administrator do first to restore the missing data disk?

Accepted Answer

Create a managed disk from the snapshot, then attach it to the VM.. The snapshot represents the missing data disk, not the OS disk. To restore it, you must first create a managed disk from the snapshot (using Azure CLI, PowerShell, or portal), then attach that disk to the VM. This preserves the existing VM configuration and applications without redeployment.

Answer

Recreate the VM from the marketplace image and restore applications manually.

Answer

Convert the snapshot directly into an operating system disk and replace the VM.

Answer

Increase the VM size so that Azure automatically recreates the missing disk.

Question 14

Match each Azure VM access feature to the task it supports.

Accepted Answer

Azure Bastion: Provides secure RDP/SSH to VMs without public IP. Azure Bastion provides secure RDP/SSH without public IP; JIT restricts port access; NSGs filter traffic; Azure AD authentication enables identity-based login; Private Link ensures private connectivity; Firewall offers centralized control.

Answer

Azure AD authentication: Provides secure RDP/SSH without public IP

Answer

Private Link: Manages firewall rules centrally

Question 15

Based on the exhibit, what should the administrator do to meet the performance requirement without rebuilding the server?

Accepted Answer

Resize the VM to a larger SKU that provides more vCPU and RAM.. Resizing the VM to a larger SKU with more vCPU and RAM directly addresses the performance requirement by providing additional compute and memory resources to the existing server without requiring a rebuild. This is the correct approach because the VM's current SKU is insufficient for the workload, and Azure allows resizing within the same hardware family or to a compatible series, preserving the OS and application state.

Answer

Attach an additional data disk and move the application binaries to it.

Answer

Redeploy the VM from a different marketplace image.

Answer

Place the VM in an availability set to spread processing across hosts.
