You are designing an AI solution that will analyze millions of pictures. You need to recommend a solution for storing the pictures. The solution must minimize costs.
Which storage solution should you recommend?

A. an Azure Data Lake store
B. Azure File Storage
C. Azure Blob storage
D. Azure Table storage

Q

You are configuring data persistence for a Microsoft Bot Framework application. The application requires a structured NoSQL cloud data store.
You need to identify a storage solution for the application. The solution must minimize costs.
What should you identify?

A. Azure Blob storage
B. Azure Cosmos DB
C. Azure HDInsight
D. Azure Table storage

A

Correct Answer: D

Table Storage is a NoSQL key-value store for rapid development using massive semi-structured datasets

You can develop applications on Cosmos DB using popular NoSQL APIs.
Both services have a different scenario and pricing model.
While Azure Storage Tables is aimed at high capacity on a single region (optional secondary read only region but no failover), indexing by PK/RK and storage- optimized pricing, Azure Cosmos DB Tables aims for high throughput, global distribution (multiple failover), SLA-backed predictive performance with automatic indexing of each attribute/property and a pricing model focused on throughput.

Q

You have several AI applications that use an Azure Kubernetes Service (AKS) cluster. The cluster supports a maximum of 32 nodes.
You discover that occasionally and unpredictably, the application requires more than 32 nodes.
You need to recommend a solution to handle the unpredictable application load.
Which scaling method should you recommend?

A. horizontal pod autoscaler
B. cluster autoscaler
C. manual scaling
D. Azure Container Instances

A

Correct Answer: B

To keep up with application demands in Azure Kubernetes Service (AKS), you may need to adjust the number of nodes that run your workloads. The cluster autoscaler component can watch for pods in your cluster that can’t be scheduled because of resource constraints. When issues are detected, the number of nodes is increased to meet the application demand. Nodes are also regularly checked for a lack of running pods, with the number of nodes then decreased as needed. This ability to automatically scale up or down the number of nodes in your AKS cluster lets you run an efficient, cost-effective cluster.
