AZ-304 Exam - Question 187

Question

You need to recommend a solution to deploy containers that run an application. The application has two tiers. Each tier is implemented as a separate Docker

Linux-based image. The solution must meet the following requirements:

✑ The front-end tier must be accessible by using a public IP address on port 80.

✑ The backend tier must be accessible by using port 8080 from the front-end tier only.

✑ Both containers must be able to access the same Azure file share.

✑ If a container fails, the application must restart automatically.

✑ Costs must be minimized.

What should you recommend using to host the application?

Examice · Accepted Answer

Azure Container Instances (ACI) is the appropriate solution for deploying the given application with two Docker Linux-based images. ACI allows for the creation of container groups, enabling both containers to be managed together and share the same Azure file share, which satisfies the requirement for both containers to access the same storage. Additionally, ACI supports networking controls that allow the front-end container to be accessible via a public IP on port 80 and the backend container to be accessible on port 8080 from the front-end. ACI also includes restart policies such as 'OnFailure', ensuring the application restarts automatically if a container fails. Importantly, ACI is a cost-effective solution compared to other options like AKS or Azure Service Fabric, aligning with the requirement to minimize costs.

arseyam · Answer

Azure Container Instances is the correct answer.
It has networking controls (public, private) and supports Restart policies set to "OnFailure" by default.

nicksu · Answer

I would say that when microsoft tells to use two containers - it would nearly always be the ACI, when there should be more containers or kind of orchestration, then it would be the AKS

gcpjay · Answer

The given answer is correct, but the reasoning is inadequate. We can have group both the container in an Azure Container Instance group and both can access the same Azure File share.

"two tiers" so 2 containers would do

C is the answer

MaoLi · Answer

“Azure Container Service will be retired on January 31, 2020, and is no longer recommended for new resources." go with AKS

Persistent storage;
To retrieve and persist state with Azure Container Instances, we offer direct mounting of Azure Files shares backed by Azure Storage.
Secondly has restart policy;

if anyone is interested, here's a comparison between ACI And AKS.

Az_Sasi · Answer

Why not AKS?
https://docs.microsoft.com/en-us/azure/container-instances/container-instances-overview
For scenarios where you need full container orchestration, including service discovery across multiple containers, automatic scaling, and coordinated application upgrades, we recommend Azure Kubernetes Service (AKS).

leo_az300 · Answer

answer is correct.
2 containers in one Azure container group. 
xpose port 80. port 8080 is only for internal use. 
Both container can access Azure File Share in Azure container Group. 
Set up Restart Policy to OnFailure. 
Cost is less than other 2 options.

poplovic · Answer

ACI is correct. 
1. Linux so we can use container group
2. Azure file share is very simple in ACI 
there is an example in MS doc

Tos_123 · Answer

A
Based on Microsoft AKS is the recommended solution for Linux containers

manderda · Answer

Why is Azure Service Fabric not possible?

BoxMan · Answer

Pretty certain it is correct with C.  The item about "restart automatically" is what AKS/Orchestrators do and ACI doesn't.

"Azure Container Instances enables a layered approach to orchestration, providing all of the scheduling and management capabilities required to run a single container, while allowing orchestrator platforms to manage multi-container tasks on top of it." from:
