D. A DDoS knocks a webpage offline by spamming the IP with loads of traffic so it over loads the server.
Answer:
A network attached storage (NAS) device is a server connected to a network with the sole purpose of providing storage. NAS devices often use a RAID configuration. An external hard disk is a separate freestanding hard disk that connects with a cable to a USB or FireWire port on the system unit or communicates wirelessly. External hard disks have storage capacities up to 4 TB and more. A removable hard disk can be inserted or removed from a built-in or external drive. Removable hard disks have storage capacities up to 1 TB. A disk controller consists of a special-purpose chip and electronic circuits that control the transfer of data, instructions, and information from a disk to and from the system bus and other components in a computer. A hard disk controller may be part of the hard disk on the motherboard, or it may be a separate adapter card inside the system unit.

Explanation:
Formulas!D11: =C11*0.0675
4 / 7 (57.1%)
Feedback:
[-2] The formula in cell D11 does not reference the sales tax rate
[-1] The tax rate reference is not absolute
Copy the formula you used in cell D11 down to calculate the sales tax amount for the remaining transactions.

Feedback:
Construct a formula in cell E11 to calculate the total amount for transaction 578. Be sure to appropriately reference the transaction amount in cell C11 and the sales tax amount in cell D11 so that you can reuse your formula to calculate the total for the remaining transactions.
Formulas!E11: =SUM(C11:D11)

Feedback:
Copy the formula you used in cell E11 down to calculate the total for the remaining transactions.

Feedback:
Use the SUM function to calculate the “Grand Total” in for all transactions in cell E24.
Formulas!E24: =SUM(E11:E23)
