Exam AZ-400 topic 6 question 22 discussion

${{ parameters['solution'] }} # index syntax ${{ parameters.solution }} # property dereference syntax https://learn.microsoft.com/en-us/azure/devops/pipelines/process/templates?view=azure-devops#template-expressions

To reference the outputfile parameter in a YAML template for Azure Pipelines, you can use the ${{ parameters.outputfile }} syntax or the ${{ parameters['outputfile'] }} syntax. Both of these methods are valid and commonly used. So, the correct options are: A. ${{parameters.outputfile}} E. ${{parameters['outputfile']}}

Agree with answer

AE is the answer. https://learn.microsoft.com/en-us/azure/devops/pipelines/process/runtime-parameters?view=azure-devops&tabs=script Parameters are only available at template parsing time. Parameters are expanded just before the pipeline runs so that values surrounded by ${{ }} are replaced with parameter values. Use variables if you need your values to be more widely available during your pipeline run.

AE https://docs.microsoft.com/en-us/azure/devops/pipelines/process/templates?view=azure-devops#template-expressions

Answer correct A & B Parameters can be referenced with Template expressions. Template Expression there is 2 forms of syntax : ${{ parameters['solution'] }} # index syntax & ${{ parameters.solution }} # property dereference syntax https://docs.microsoft.com/en-us/azure/devops/pipelines/process/templates?view=azure-devops#template-expressions Regarding to C : this is Macro syntax and can be used to reference variables at runtime cant use it with parameters https://docs.microsoft.com/en-us/azure/devops/pipelines/process/variables?view=azure-devops&tabs=yaml%2Cbatch#runtime-expression-syntax

I always use ${{parameters.foo}} and sometimes maybe you will use it with IF then you can use: ${{ if eq(length(parameters.foo), 0) }}: Thus, only A and C fit in.

From what is seen from the link, I would take A and C

Should be A,C
