 |
| ( | B | ) | | DMA4 |
|
| ( | C | ) | | DMA5 |
|
| ( | D | ) | | DMA6 |
|
| ( | E | ) | | DMA7 |
The Correct Answer is: A
The most chosen answer was [ B ] :: [ DMA4 ]

Your customer has bought a second hard disk and added it an existing computer. The first hard disk is having one primary partition and one Extended partition. The extended partition is divided into two logical drives D and E. When you install the second hard drive and format it, what would be the drive letter assigned to the first logical drive on the extended partition of first hard disk? Assume that the second hard disk has one primary partition and only one logical drive on the Extended partition.

| ( | A | ) | | "D" |
|
| ( | B | ) | | "E" |
|
| ( | C | ) | | "F" |
|
| ( | D | ) | | "G" |
|
| ( | E | ) | | None of the above |
The Correct Answer is: B
Explanation:
The
revised drive assignment looks as follows:
Drive
1: C (Primary Partition), E (First logical Drive), F (Second logical Drive)
Drive
2: D (Primary Partition), G( for
Logical drive on Extended Partition)
In
addition, please note the following:
DOS,
Windows3.1 Windows 95/ 98 operating systems share the following criteria:
1.
Each can have only one primary partition per hard disk
2.
The primary partition is automatically assigned a drive letter
3.
Each hard disk can have only one Extended partition
4.
You can create one or more logical drives in the Extended partition.
5.
The drive letters are assigned manually to logical drives.
How many devices, a 16 bit SCSI-2 can support?
(this question provided by simulationexams.com)
| ( | A | ) | | 8 |
|
| ( | B | ) | | 16 |
|
| ( | C | ) | | 7 |
|
| ( | D | ) | | 14 |
|
| ( | E | ) | | None of the above |
The Correct Answer is: B
Explanation:
For a 16-bit Wide SCSI, there are 16 possible
SCSI Ids, 0-15. A standard 8-bit SCSI can support only 8 devices (including SCSI
card), the Ids allows are 0-7.
SCSI ID - 0=bootable drive, 7=controller, 1-6=any
other devices
SCSI 3 ultra-wide - 16 devices, 0=bootable drive, 15=controller
