Description automatically generated
Box 1: 3
Scenario: App1 must meet the following requirements:
Be hosted in an Azure region that supports availability zones.
Maintain availability if two availability zones in the local Azure region fail.
A host group is a resource that represents a collection of dedicated hosts. You create a host group in a region and an
availability zone, and add hosts to it.
Use Availability Zones for fault isolation
Availability zones are unique physical locations within an Azure region. Each zone is made up of one or more
datacenters equipped with independent power, cooling, and networking. A host group is created in a single availability
zone. Once created, all hosts will be placed within that zone. To achieve high availability across zones, you need to
create multiple host groups (one per zone) and spread your hosts accordingly.
Box 2: 1
Scenario: App1 must meet the following requirements:
Be hosted on Azure virtual machines that support automatic scaling.
An Azure virtual machine scale set can automatically increase or decrease the number of VM instances that run your
application. This automated and elastic behavior reduces the management overhead to monitor and optimize the
performance of your application.

You have an Azure subscription that contains a storage account.
An application sometimes writes duplicate files to the storage account.
You have a PowerShell script that identifies and deletes duplicate files in the storage account. Currently, the script is
run manually after approval from the operations manager.
You need to recommend a serverless solution that performs the following actions:
Runs the script once an hour to identify whether duplicate files exist
Sends an email notification to the operations manager requesting approval to delete the duplicate files
Processes an email response from the operations manager specifying whether the deletion was approved
Runs the script if the deletion was approved
What should you include in the recommendation?
A. Azure Logic Apps and Azure Functions
B. Azure Pipelines and Azure Service Fabric
C. Azure Logic Apps and Azure Event Grid
D. Azure Functions and Azure Batch
Answer: A
Explanation:
You can schedule a powershell script with Azure Logic Apps.
When you want to run code that performs a specific job in your logic apps, you can create your own function by using
Azure Functions. This service helps you create Node.js, C#, and F# functions so you don’t have to build a complete
app or infrastructure to run code. You can also call logic apps from inside Azure functions. Azure Functions provides
serverless computing in the cloud and is useful for performing tasks such as these examples:

HOTSPOT
Your company has the divisions shown in the following table.
You plan to deploy a custom application to each subscription.
The application will contain the following:
A resource group
An Azure web app
Custom role assignments
An Azure Cosmos DB account
You need to use Azure Blueprints to deploy the application to each subscription.
What is the minimum number of objects required to deploy the application? To answer, select the appropriate options
in the answer area. NOTE: Each correct selection is worth one point.


Answer:


Explanation:
Box 1: 2
One management group for East, and one for West.
When creating a blueprint definition, you’ll define where the blueprint is saved. Blueprints can be saved to a
management group or subscription that you have Contributor access to. If the location is a management group, the
blueprint is available to assign to any child subscription of that management group.
Box 2: 2
Box 3: 4
One assignment for each subscription.
"Assigning a blueprint definition to a management group means the assignment object exists at the management group.
The deployment of artifacts still targets a subscription. To perform a management group assignment, the Create Or
Update REST API must be used and the request body must include a value for properties.scope to define the target
subscription." https://docs.microsoft.com/en-us/azure/governance/blueprints/overview#blueprint-assignment

Question: 81
HOTSPOT
You have an Azure Load Balancer named LB1 that balances requests to five Azure virtual machines.
You need to develop a monitoring solution for LB1.
The solution must generate an alert when any of the following conditions are met:
A virtual machine is unavailable.
Connection attempts exceed 50,000 per minute.
Which signal should you include in the solution for each condition? To answer, select the appropriate options in the
answer area. NOTE: Each correct selection is worth one point.


Answer:

Explanation:
Graphical user interface, text, application
Description automatically generated
Box 1: Data path availability
Standard Load Balancer continuously exercises the data path from within a region to the load balancer front end, all
the way to the SDN stack that supports your VM. As long as healthy instances remain, the measurement follows the
same path as your application’s load-balanced traffic. The data path that your customers use is also validated. The
measurement is invisible to your application and does not interfere with other operations.
Note: Load balancer distributes inbound flows that arrive at the load balancer’s front end to backend pool instances.
These flows are according to configured load-balancing rules and health probes. The backend pool instances can be
Azure Virtual Machines or instances in a virtual machine scale set.
Box 2: SYN count
SYN (synchronize) count: Standard Load Balancer does not terminate Transmission Control Protocol (TCP)
connections or interact with TCP or UDP packet flows. Flows and their handshakes are always between the source and
the VM instance. To better troubleshoot your TCP protocol scenarios, you can make use of SYN packets counters to
understand how many TCP connection attempts are made. The metric reports the number of TCP SYN packets that
were received.
Question: 82
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains
a unique solution that might meet the stated goals. Some question sets might have more than one correct solution,
