Exam PL-100 topic 1 question 2 discussion

Collection and Global variable: Global variables: Holds a number, text string, Boolean, record, table, etc. that can be referenced from anywhere in the app Collections: Holds a table that can be referenced from anywhere in the app. Allows the contents of the table to be modified rather than being set as a whole. Can be saved to the local device for later use. https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/working-with-variables

COLLECTION AND GLOBAL VARIABLE IT IS

Collection and Global Variable (to reference the value anywhere in the app, in this case all pages)

Collection and Global Variable

Collection and Global Variable is correct

Collection and Global variables.

Collection and Environment Variable are correct. https://learn.microsoft.com/en-us/power-apps/maker/data-platform/environmentvariables#use-data-source-environment-variables-in-canvas-apps

So, B. No, it does not

can't we have only one answer ?

It's collection and environmental Variable. The same answer on measure up.

Collection and Global variables can hold a dataset/table Context variable is used as parameter/simple value. Environment variable is used for controlling environment settings, across multiple apps. Use case: export/import solutions https://learn.microsoft.com/en-us/power-apps/maker/canvas-apps/working-with-variables

Collection & Global Variable.

Environment & Collection

Tabular data can be stored on a var in an array format, so Global or environment should be suitable options?

The requirement is: You need to configure the use of a suitable data store. Collection is local to the app, and also not across users, so data retrieval from the source is kept to a minimum once collected. Others: Environmental variable is more concerned with use of the app in different environments/solutions Global variable is temp data structure for ‘programming use’ between different app modules (screens) for speed enhancement: It is not a direct answer (seems Collection is a special type of global variable) “Using a Global variable (using Set() function) has a better performance than Context variable (using UpdateContext() function) within a canvas ap” https://powerusers.microsoft.com/t5/Building-Power-Apps/Variable-Types-and-Best-Practice/td-p/178042 https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/working-with-variables

Environment Variables are used to support easier solution export import to other tenants.

FYSA, Environment Variables are used with Power Automate, this question is specifically asking about a CANVAS app. So you would need to use Collections and a Global Variable.
