What you will learn
- Explain what use application gateways and load balancers accomplishes in Cloud Infrastructure on Azure.
- Use the demonstrated command or workspace procedure to practise use application gateways and load balancers.
- Compare the visible output with your own training result and identify a likely failure.
Use application gateways and load balancers
Suppose you are working with a dedicated training subscription with cost alerts and minimal access. The subject is use application gateways and load balancers. Verify the active tenant and subscription before proceeding. Practise use application gateways and load balancers in a training environment, not by experimenting on a team’s live system. Read the command or UI step carefully: its target, options and access permissions matter. Compare the visible result with the stated goal and identify what would be different if the input were missing, a setting were invalid, or access were denied. Keep the result as your evidence.
- What matters: Verify the active tenant and subscription before proceeding.
- Practical syntax: In the example, az account show --query "{subscription:id,tenant:tenantId}" -o json is the first operation to understand. Read its flags and the context it targets.
- What to look for: For use application gateways and load balancers, inspect the result shown immediately after Example 1 and compare it with your practice run.
- Avoid a real-world mistake: While practising use application gateways and load balancers, follow this caution: An incorrect subscription or tenant can create costs and permission problems; verify both before a change.
Technical vocabulary
Use application gateways and load balancers
Verify the active tenant and subscription before proceeding.
Command
The tool instruction for this topic begins with az account show --query "{subscription:id,tenant:tenantId}" -o json. Read its target and options before using it.
Result
For use application gateways and load balancers, the example result is: {"subscription":"...","tenant":"..."}. Actual remote-service output depends on your environment.
Examples
Use use application gateways and load balancers
az account show --query "{subscription:id,tenant:tenantId}" -o json{"subscription":"...","tenant":"..."}Explanation: Verify the active tenant and subscription before proceeding.
Inspect the working context
az account show --query "{name:name,id:id}" -o json{"name":"Training subscription","id":"..."}Explanation: Confirm that this action will use the intended training subscription. The value shown is an illustration, so compare your actual response.
Investigate a problem
az account list --query "[].{name:name,isDefault:isDefault}" -o table(subscription list and default selection)
Explanation: Use this separate diagnostic command when checking use application gateways and load balancers. Interpret warnings and missing permissions before changing anything.
Practise and build
Try it: Use application gateways and load balancers
Repeat Example 1 for use application gateways and load balancers in a permitted lab. Change one safe input or setting, then record the real result rather than copying the sample Output above.
Check your approach
Verify the active tenant and subscription before proceeding. If the result differs, first inspect the active account or workspace and review your command or action.
Find the issue
Imagine that your training subscription is not in the expected state after this exercise. Identify the missing prerequisite or permission and write a safe diagnostic procedure.
Show a possible resolution
An incorrect subscription or tenant can create costs and permission problems; verify both before a change. Use the separate diagnostic example to gather evidence before applying a change.
Level project: Build a simple storage-and-app service
Use use application gateways and load balancers as a specific component of the project. Document the feature, why it belongs in the workflow, the steps taken and the verified state. Keep the result in your private learner portfolio.
Questions
01What does use application gateways and load balancers help you accomplish?
Verify the active tenant and subscription before proceeding.
02What action starts the use application gateways and load balancers demonstration?
az account show --query "{subscription:id,tenant:tenantId}" -o json
03What does the first Output tell you about use application gateways and load balancers?
The illustrated result is {"subscription":"...","tenant":"..."}; your environment may display other identifiers, counts or status information.
04What should you check if use application gateways and load balancers does not behave as shown?
An incorrect subscription or tenant can create costs and permission problems; verify both before a change.
Summary
Verify the active tenant and subscription before proceeding. You can now connect this feature to your level project. Before moving to Manage virtual machine disks and images, make sure the primary demonstration works or that you can explain precisely why it did not work in your chosen environment.
