Hot Area:
Answer:
Explanation:
Box 1: Azure Traffic Manager
Traffic Manager is a DNS-based traffic load balancer that enables you to distribute traffic optimally to services across global
Azure regions, while providing high availability and responsiveness. Because Traffic Manager is a DNS-based load-
balancing service, it load balances only at the domain level. For that reason, it can't fail over as quickly as Front Door,
because of common challenges around DNS caching and systems not honoring DNS TTLs.
Incorrect Answers:
Front Door is an application delivery network that provides global load balancing and site acceleration service for web
applications.
Box 2: Azure Load Balancer
Azure Load Balancer is a high-performance, ultra low-latency Layer 4 load-balancing service (inbound and outbound) for all
UDP and TCP protocols. It is built to handle millions of requests per second while ensuring your solution is highly available.
Azure Load Balancer is zone-redundant, ensuring high availability across Availability Zones.
Incorrect Answers:
Front Door is an application delivery network that provides global load balancing and site acceleration service for web
applications. Reference:

Question 4 Topic 7, Mixed Questions
Your company develops Azure applications.
You need to recommend a solution for the deployment of Azure subscriptions. The solution must meet the following
requirements:
Provision resource groups.
Support deployments across all Azure regions.
Create custom role-based access control (RBAC) roles.
Provide consistent virtual machine and virtual network configurations.
What should you include in the recommendation?
- A. Azure Policy
- B. Anomaly Detector
- C. Azure Resource Manager templates
- D. Azure Blueprints
Answer:
D
Explanation:
Resource groups: You can scope your deployment to a resource group. You use an Azure Resource Manager template
(ARM template) for the deployment.
Regions: If you have a template spec in one region and want to move it to new region, you can export the template spec
and redeploy it.
RBAC: Azure role-based access control (Azure RBAC) is the authorization system you use to manage access to Azure
resources. To grant access, you assign roles to users, groups, service principals, or managed identities at a particular scope.
In addition to using Azure PowerShell or the Azure CLI, you can assign roles using Azure Resource Manager templates.
Templates can be helpful if you need to deploy resources consistently and repeatedly
You can setup Virtual machines and virtual network configurations in an Azure Resource Manager template. Reference:

Question 10 Topic 7, Mixed Questions
You have an Azure subscription that contains two applications named App1 and App2. App1 is a sales processing
application. When a transaction in App1 requires shipping, a message is added to an Azure Storage account queue, and
then App2 listens to the queue for relevant transactions.
In the future, additional applications will be added that will process some of the shipping requests based on the specific
details of the transactions.
You need to recommend a replacement for the storage account queue to ensure that each additional application will be able
to read the relevant transactions.
What should you recommend?
- A. one Azure Service Bus topic
- B. multiple storage account queues
- C. one Azure Data Factory pipeline
- D. one Azure Service Bus queue
Answer:
A
Explanation:
A queue allows processing of a message by a single consumer. In contrast to queues, topics and subscriptions provide a
one-to-many form of communication in a publish and subscribe pattern. It's useful for scaling to large numbers of recipients.
Each published message is made available to each subscription registered with the topic. Publisher sends a message to a
topic and one or more subscribers receive a copy of the message, depending on filter rules set on these subscriptions.

Question 12 Topic 7, Mixed Questions
You have an Azure subscription.
You need to deploy an Azure Kubernetes Service (AKS) solution that will use Linux nodes. The solution must meet the
following requirements:
Minimize the time it takes to provision compute resources during scale-out operations. Support autoscaling of Linux
containers. Minimize administrative effort.
Which scaling option should you recommend?
- A. Virtual Kubelet
- B. cluster autoscaler
- C. horizontal pod autoscaler
- D. AKS virtual nodes
Answer:
B
Explanation:
About the cluster autoscaler.
AKS clusters can scale in one of two ways:
The cluster autoscaler watches for pods that can't be scheduled on nodes because of resource constraints. The cluster
then automatically increases the number of nodes. The horizontal pod autoscaler uses the Metrics Server in a Kubernetes
cluster to monitor the resource demand of pods. Reference:
https://docs.microsoft.com/en-us/azure/aks/cluster-autoscaler
Question 13 Topic 7, Mixed Questions

Question 14 Topic 7, Mixed Questions
You manage an on-premises network and Azure virtual networks.
You need to create a secure connection over a private network between the on-premises network and the Azure virtual
networks. The connection must offer a redundant pair of cross connections to provide high availability.
What should you recommend?
- A. Azure Load Balancer
- B. VPN Gateway
- C. ExpressRoute
- D. virtual network peering
Answer:
B
Explanation:
Every Azure VPN gateway consists of two instances in an active-standby configuration. For any planned maintenance or
unplanned disruption that happens to the active instance, the standby instance would take over (failover) automatically.
Reference:
https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-highlyavailable
Question 15 Topic 7, Mixed Questions
You manage an application instance. The application consumes data from multiple databases. Application code references
database tables using a combination of the server, database, and table name.
You need to migrate the application data to Azure.
To which two Azure services could you migrate the application to achieve the goal? Each correct answer presents a
complete solution.
NOTE: Each correct selection is worth one point.
- A. Azure SQL Managed Instance
- B. Azure SQL Database
- C. SQL Server in an Azure virtual machine
- D. SQL Server Stretch Database
Answer:
A D
Explanation:
A: The managed instance deployment model is designed for customers looking to migrate a large number of apps from on-
premises or IaaS, self-built, or ISV provided environment to fully managed PaaS cloud environment, with as low migration
effort as possible. Using the fully automated Data Migration Service (DMS) in Azure, customers can lift and shift their on-
premises SQL Server to a managed instance that offers compatibility with SQL Server on-premises and complete isolation of
customer instances with native VNet support.
D: Access your SQL Server data seamlessly regardless of whether it's on-premises or stretched to the cloud. You set the
policy that determines where data is stored, and SQL Server handles the data movement in the background. The entire table
is always online and queryable. And, Stretch Database doesn't require any changes to existing queries or applications - the
location of the data is completely transparent to the application. Reference:
