THE SCHEDULED TASKS GRAPHICAL ADMINISTRATIVE UTILITY IS CAPABLE OFMODIFYING TASKS CREATED WITH THE AT COMMAND

7.

Correct Answers: D

A. Incorrect:

The Scheduled Tasks graphical administrative utility is capable of

modifying tasks created with the AT command. Further, AT cannot display the

task because tasks that have been modified by the Scheduled Tasks are not visi-

ble to AT.

B. Incorrect:

The Scheduled Tasks graphical administrative utility can update tasks

created with the AT command, but makes the tasks invisible to the AT command-

line utility after they have been modified.

C. Incorrect:

The Scheduled Tasks utility does not duplicate tasks when making a

modification, but it does make them invisible to AT.

D. Correct:

The Scheduled Tasks utility and the AT command maintain entirely sep-

arate lists of scheduled tasks. Although the Scheduled Tasks utility can display

tasks created with the AT command, it cannot directly modify those tasks. To mod-

ify a task created with the AT command, the Scheduled Tasks utility removes the

task from the AT command’s list and adds the task to its own list. Therefore, tasks

created with AT become invisible to AT after being modified with the Scheduled

Tasks utility.
