Microsoft Azure

Q1. You need to create an application in Azure AD representing the Kineteco Web App so you can assign directory permissions to the app. To create the application identity, which command will you run?

  • bash az ad app permission grant -display-name $appName \ ...
  • bash az ad app credential create -display-name $appName \ ...
  • bash az ad app create -display-name $appName \ ...
  • bash az ad app permission ass -display-name $appName \ ...

Q2. You need to deliver a mobile push notification feature for the Kineteco Retail app, hosted in Azure App Service. The solution should minimize cost, complexity, and development effort. Which option should you choose?

  • Notification Hub
  • Event Grid
  • Twilio
  • Service Bus

Explanation: Twilio is an SMS notification app, also not from Microsoft. Event Grid can be techincally used for this purpose but it's a more generic event-broadcasting service. Service Bus is another generic publish-subscribe solution. Finally Notification Hubs are specifically designed for push-notifications.

Q3. Your application hosted in Azure App Service needs to retrieve secrets from Azure Key Vault. Which choice is NOT a way to authenticate to Key Vault?

  • service principal and a certificate
  • managed identity
  • service principal and a secret
  • shared access key

Reference: Azure Key Vault Developer's Guide lists 3 available methods. The shared access key does not exist in Azure at all, the closest term is shared access signature (SAS) but it's used to access Azure Storage only.

Q4. You added a persistent volume claim to your apps YAML manifest. When you attempt to deploy to an existing AKS cluster there is no persistent volume available. What should you do?

  • Do nothing. The API server will provision additional storage automatically
  • Add a data disk definition for the AKS cluster to your apps YAML manifest
  • Add a data disk to each Kubernetes cluster node and reattempt app deployment
  • Provision an Azure Files instance and reattempt app deployment

Q5. Your corporate web application is hosted in Azure regional data centres around the world. You need to route user requests to the closest service endpoint based on response latency. Which routing method should you use?

  • Application gateway
  • Front Door
  • API Management
  • Traffic manager

Q6. You are developing a release strategy for several related software components. You need to reference variable groups and secure files across multiple build and release pipelines. What is the most efficient way to store and reference these assets from the pipeline?

  • Add the assets to a git repository
  • Add the assets in Key Vault
  • Add the assets to an encrypted volume
  • Add the assets to a library

Q7. You need to grant full access for an app to a temporary Azure storage account. Configuring access should require minimum effort. Which option should you use?

  • Azure AD user account
  • Shared access signature
  • Shared key
  • Certificate

Explanation: Shared access signature exists exactly for the purpose of giving a temporary access. Azure AD user account is not temporary so it needs to be managed. Creating/revoking Certificates for temporary access is just too much hassle.

Q8. The Kineteco web app runs in an Azure Kubernetes Service. You need to monitor feature use and user navigation paths to identify where improvements are needed. What should you do?

  • Configure application insights cohort
  • Install the Log Analytics agent and configure Azure Monitor for Containers
  • Install the App Insights on AKS nodes
  • Add instrumentation to your app to send usage analytics with Application Insights.

Notes: Needs to be clarified. The Container Monitoring doc explicitly mentions that it's not for AKS. 3 and 4 look right

Q9. Which choice is not a valid trigger for an Azure functions?

Q12. You need to host a community website for your neighborhood association. The site contains static content, including HTML, CSS, and a few pages with client-side JavaScript. The site contains no sensitive information, and CORS support is unnecessary. The association has limited funds to pay for hosting, so the solution should be as inexpensive as possible. Which option should you use?

  • Azure Storage static website
  • static website with Azure CDN
  • App Service on Consumption plan
  • App Service on Standard plan

Q13. Your organization delivers a number of RESTful web services to customers around the world. You need to deploy cloud infrastructure to deliver these services to paying customers, including authentication, request throttling and routing of requests to the closest service endpoint. Which solution should you choose?

  • Front door
  • API Management
  • Traffic manager
  • Application Gateway

Hint: If you see the words REST and throttling - the answer is almost always API Management. It's the most expensive solution but is specifically designed to proxy the REST API.

Q14. You have a .NET app running on a VM Scale set. You need to monitor application performance without modifying the code. The solution should minimize the cost. What should you do?

  • Enable Network Performance Monitor on the VMs.

  • Create a service principal in Azure AD. Then add user to the AKS security group.
  • Create an App ID in Azure AD. Then create a service principal for the server app.

Q17. Which access protocol does Azure Files not support?

  • Network File System (NFS)
  • HTTPS
  • REST API
  • Server Message Block(SMB)

Reference: What is Azure Files? page mentions the supported protocols.

Q18. You are writing an app for a sales team. You need to implement security in SQL Server to ensure that sales representatives see customer financial information only for customers whom they manage. Your app must make this transparent to the user. Which SQL data security option should you choose?

  • Manually deprovision unneeded pods.
  • Do nothing. HPA will initiate scale down automatically.
