Which are not one of the application layer protocols?

• DNS

• FTP

• SMTP

• FNP

What is the name of the data connection commonly used for hard drives and optical drives?

• RAID
• ATX
• RAM
• SATA

1. When implementing__________________________, a mirrored volume stores data to two duplicate disks simultaneously. If one disk fails, data is present on the other disk, and the system switches immediately from the failed disk to the functioning disk. Mirroring provides fault tolerance for a single disk failure, but does not increase performance.

• RAID 1

• RAID 0

• RAID 5

• RAID 10

Which of the following uses striping without fault tolerance?

• RAID 1
• RAID 0
• RAID 5
• Expanded volume set

What is TCP used for?

• To send information across the internet in packets

• To ensure that information is sent to the correct computer

• To send mail across the internet

• To transmit webpages across the internet

Which RAID level provides disk mirroring?

• RAID 1

• RAID 3

• RAID 4

• RAID 50

1. A_____________________________ volume stripes data across mirrored pairs and across multiple disks for data redundancy. If a single disk fails, its data can be recovered using the mirrored information stored on the remaining disks. If two disks in the same mirrored pair fail, all data will be lost because there is no redundancy in the striped sets.

• RAID 10

• RAID 1

• RAID 5

• RAID 0
