After you define variables, which command allows you to perform operations on them within your automation tasks?

Which of the following variables is used in Error Handling?

A locker administrator needs to take a long leave and wants to assign a back-up to perform Locker administrator tasks in their absence. The locker administrator does not want the back-up to add users to the existing lockers, but is comfortable with the back-up adding and editing existing credential variables of the lockers. The back-up can also change access levels of existing users inside the lockers.
How can the locker administrator achieve this?

Which of the following loops are offered by the AAE Client? (Choose three)

The locker administrator informs the developer to use the credentials from the locker that the developer has been provided access to. The developer logs into the control room to learn the names of the variables and use them during development but finds nothing created inside the locker. The developer creates their own credential variables inside the locker but is unable to use these credential variables during development.
