Topic 5: Misc. Questions
You are developing a multi-tier app named App1 that will be hosted on Azure virtual machines. The peak utilization periods for App1 will be from 8 AM to 9 AM and 4 PM to 5PM on weekdays.
You need to deploy the infrastructure for App1. The solution must meet the following requirements:
• Support virtual machines deployed to four availability zones across two Azure regions.
• Minimize costs by accumulating CPU credits during periods of low utilization.
What is the minimum number of virtual networks you should deploy, and which virtual machine size should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
You have the Azure resources shown in the following table.
You need to deploy a new Azure Firewall policy that will contain mandatory rules for all Azure Firewall deployments. The new policy will be configured as a parent policy for the existing policies. What is the minimum number of additional Azure Firewall policies you should create?
A.
0
B.
1
C.
2
D.
3
1
Explanation:
Firewall policies work across regions and subscriptions.
Place all your global configurations in the parent policy.
Note: Policies can be created in a hierarchy. You can create a parent/global policy that will contain configurations and rules that will apply to all/a number of firewall instances. Then you create a child policy that inherits from the parent; note that rules changes in the parent instantly appear in the child. The child is associated with a firewall and applies configurations/rules from the parent policy and the child policy instantly to the firewall.

You are designing a cost-optimized solution that uses Azure Batch to run two types of jobs on Linux nodes. The first job type will consist of short-running tasks for a development environment. The second job type will consist of long-running Message Passing Interface (MPI) applications for a production environment that requires timely job completion.
You need to recommend the pool type and node type for each job type. The solution must minimize compute charges and leverage Azure Hybrid Benefit whenever possible.
What should you recommend? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
You are designing a solution that will include containerized applications running in an Azure Kubernetes Service (AKS) cluster.
You need to recommend a load balancing solution for HTTPS traffic. The solution must meet the following requirements:
Automatically configure load balancing rules as the applications are deployed to the cluster.
Support Azure Web Application Firewall (WAF).
Support cookie-based affinity.
Support URL routing.
What should you include the recommendation?
A.
an NGINX ingress controller
B.
Application Gateway Ingress Controller (AGIC)
C.
an HTTP application routing ingress controller
D.
the Kubernetes load balancer service
Application Gateway Ingress Controller (AGIC)
Much like the most popular Kubernetes Ingress Controllers, the Application Gateway Ingress Controller provides several features, leveraging Azure’s native Application Gateway L7 load balancer. To name a few:
URL routing
Cookie-based affinity
Secure Sockets Layer (SSL) termination
End-to-end SSL
Support for public, private, and hybrid web sites
Integrated support of Azure web application firewall
Application Gateway redirection support isn't limited to HTTP to HTTPS redirection alone. This is a generic redirection mechanism, so you can redirect from and to any port you define using rules. It also supports redirection to an external site as well.

You are designing an Azure web app.
You plan to deploy the web app to the North Europe Azure region and the West Europe Azure region. You need to recommend a solution for the web app. The solution must meet the following requirements:
Users must always access the web app from the North Europe region, unless the region fails.
The web app must be available to users if an Azure region is unavailable. Deployment costs must be minimized.
What should you include in the recommendation? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
