HOTSPOT
You need to configure Azure CDN for the Shipping web site.
Which configuration options should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

Answer:


Explanation:
Scenario: Shipping website
Use Azure Content Delivery Network (CDN) and ensure maximum performance for dynamic content while minimizing latency
and costs.
Tier: Standard
Profile: Akamai
Optimization: Dynamic site acceleration
Dynamic site acceleration (DSA) is available for Azure CDN Standard from Akamai, Azure CDN Standard from Verizon, and
Azure CDN Premium from Verizon profiles.
DSA includes various techniques that benefit the latency and performance of dynamic content. Techniques include route and
network optimization, TCP optimization, and more.
You can use this optimization to accelerate a web app that includes numerous responses that aren't cacheable. Examples
are search results, checkout transactions, or real-time data. You can continue to use core Azure CDN caching capabilities
for static data.

HOTSPOT
You need to correct the VM issues.
Which tools should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

Answer:


Explanation:
Box 1: Azure Backup
The VM is critical and has not been backed up in the past. The VM must enable a quick restore from a 7-day snapshot to
include in-place restore of disks in case of failure.
In-Place restore of disks in IaaS VMs is a feature of Azure Backup.
Performance: Accelerated Networking
Scenario: The VM shows high network latency, jitter, and high CPU utilization.
Box 2: Accelerated networking
The VM shows high network latency, jitter, and high CPU utilization.
Accelerated networking enables single root I/O virtualization (SR-IOV) to a VM, greatly improving its networking
performance. This high-performance path bypasses the host from the datapath, reducing latency, jitter, and CPU utilization,
for use with the most demanding network workloads on supported VM types.

Explanation:
Scenario:
You must minimize costs for all Azure services.
All Internal services must only be accessible from internal Virtual Networks (VNets).
Best for long-running scenarios where Durable Functions can't be used. Consider an App Service plan in the following
situations: You have existing, underutilized VMs that are already running other App Service instances.

You want to provide a custom image on which to run your functions. Predictive scaling and costs are required.


Note: When you create a function app in Azure, you must choose a hosting plan for your app. There are three basic hosting
plans available for Azure Functions: Consumption plan, Premium plan, and Dedicated (App Service) plan.
Incorrect Answers:
A: A Premium plan would be more costly. C: Need the VNET functionality.

Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the
answer area and arrange them in the correct order.
Select and Place:

Answer:


Explanation:
Step 1: Build a new application image by using dockerfile
Step 2: Create an alias if the image with the fully qualified path to the registry
Before you can push the image to a private registry, youve to ensure a proper image name. This can be achieved using the
docker tag command. For demonstration purpose, well use Dockers hello world image, rename it and push it to ACR.
# pulls hello-world from the public docker hub
$ docker pull hello-world
# tag the image in order to be able to push it to a private registry
$ docker tag hello-word /hello-world
# push the image
$ docker push /hello-world
Step 3: Log in to the registry and push image
In order to push images to the newly created ACR instance, you need to login to ACR form the Docker CLI. Once logged in,
you can push any existing docker image to your ACR instance.
Scenario:
Coho Winery plans to move the application to Azure and continue to support label creation.
LabelMaker app
Azure Monitor Container Health must be used to monitor the performance of workloads that are deployed to Kubernetes
environments and hosted on Azure Kubernetes Service (AKS).
You must use Azure Container Registry to publish images that support the AKS deployment.

following example:
[FunctionName("ResizeImage")]
public static void Run(
[BlobTrigger("sample-images/{name}")] Stream image,
[Blob("sample-images-md/{name}", FileAccess.Write)] Stream imageSmall)
{
