You are implementing a RAID storage system and have found a system with eight 100 GB drives. How much storage space will you hav

asambeis [7]

Answer:

The space available will vary between 800 GB (100%) and 400 GB (50%) of the total disks, depending on the RAID level.

The OS will handle the RAID as a single disk.

Explanation:

Each RAID level implements parity and redundancy in a different way, so the amount of disks used for this extra information will reduce the space available for actual storage.

Usual RAID levels are:

<u>RAID 0:</u> does not implement any redundancy or parity, so you will have available 100% of the total storage: 8 x 100 GB = 800 GB

<u>RAID 1:</u> Duplicates all the information in one disk to a second disk. Space is reduced in half: 400 GB

<u>RAID 5:</u> Uses the equivalent of 1 disk of parity data distributed evenly on each disk, meaning the space available is $\frac{n-1}{n}$ of the total disks: $\frac{7}{8}$ of 800 GB = 700 GB

Writting and reading the information on a RAID storage is handled by a raid controller, either implemented in hardware or software. The OS will "see" a single disk and will read or write information as usual.

vitfil [10]

Answer:

C) OpenID Connect

Explanation:

The best option is OpenID Connect because is based in OAuth, and supports multiple web based and mobile clients, and supports REST.

With OAuth, we cannot make any user authentication just provide a token to access data.

RADIUS is a networking protocol, and Shibboleth is a single sign-on log-in system for computer networks and the Internet, both not support REST.

What type of storage drive contains multiple spinning platters?

Gala2k [10]

The type of storage drive that contains multiple spinning platters is called; Hard disk drives

<h3>What is the hard disk drive?</h3>

A computer hard disk drive (HDD) is a non-volatile data storage device. Non-volatile refers to storage devices that maintain stored data when turned off.

Now, the correct answer to the question is hard disk drives. This is because a hard disk drive is comprised of a stack of spinning metal disks known as platters. Each spinning disk has trillions of tiny fragments that could possibly be magnetized in order to represent bits (1s and 0s in binary code).
