Answer:

Option 4 i.e., RDP, port 3389.

Explanation:

The User has informed the helpdesk with such an issue that involves the specialist to link to the remote server utilizing Remote Assist to access the user's screen with a quite informative and ambiguous error. Every attempt made by the technician to link to the virtual server outcomes in a message saying that the link has been denied.

So the combinations of RDP and port 3389 would be enabled on the remote computer’s firewall to allow this connection.

Where should you click to edit an existing formula?
user100 [1]

Answer:

You can edit the existing formula by clicking the cell in which formula is referenced, then edit the formula in the formula bar. (option c is correct)

Explanation:

This question is about how to edit the existing formula. In Excel, you can edit the formula. First, you have to click the cell in which the formula is written. Then you have to edit it in the formula bar. However, if you know and remember the formula, you can edit directly in the cell. But the best practice is to edit the formula in the formula bar.

Why other options are not correct.

  • In a cell that is referenced in the formula:

The cell that is referenced in the formula does not affect the formula. Because to edit something in the referenced cell, does not guarantee to affect the formula that you want to edit. To edit the existing formula, you click the cell in which formula is written, then edit it in the formula bar.

  • In the first blank cell of the worksheet

It is not necessary, that there would be a formula in the first cell. But, if there is a formula in the first cell, you should edit the formula directly in the formula bar.

  • In the status bar

You can't edit the existing formula in the status bar because the status bar is used for showing the status of actions you are doing in excel. The status bar is shown at the bottom of the excel sheet.
