 Q 43. Which of the following is an optical digital data storage device?

A.   Floppy disk

B.   Micro SD

C.   BluRay disk

D.  Hard disk

ANSWER: C

EXPLANATION

Optical digital data storage

It is a storage method that uses the laser to store and retrieve data from optical media. For e.g. CD, DVD, BluRay disk, etc.

Magnetic storage media

It is a storage method that uses a magnetized medium to store and retrieve data. It includes hard disks, floppy disks, magnetic tape, magnetic stripes on credit cards, SuperDisk, Tape cassette, Zip diskette, etc.

Flash memory devices

An electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed, For e.g. Flash drive, Memory card, Compact Flash, SD Card, SSD, xD-Picture Card (EXtreme Digital Picture Card), SDHC card (Secure Digital High Capacity), NVMe (Non-Volatile Memory Express), MultiMediaCard, etc.

 Q 44.  Which of the following technique is used to prevent altering of data on suspected drives?

A.   Encryption

B.   Write blocking

C.   Imaging

D.  Cloning

ANSWER: B

EXPLANATION

Write Blocker

It is a tool designed to prevent any write access to the hard disk, thus permitting read-only access to the data storage devices without compromising the integrity of the data. A write blocking if used correctly can guarantee the protection of the chain of custody. NIST (National Institute of Standards and Technology) has issued a set of general guidelines for write blocking requirements:

1.     Not allow a protected drive to be changed.

2.     Not prevent any operations to a drive that is not protected.

3.     Not prevent obtaining any information from or about any drive.

 Q 45. To verify the integrity of the original Hard Disk, we use ____________

A.   Password

B.   Hash value

C.   Cryptography

D.  Blockchain

ANSWER: B

EXPLANATION

Blockchain

·       It is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system.

·       It is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.

·       Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger.

·       The decentralized database managed by multiple participants is known as Distributed Ledger Technology (DLT).

·       Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a hash.

Hash values

·       It can be thought of as fingerprints for files.

·       The contents of a file are processed through a cryptographic algorithm, and a unique numerical value – the hash value - is produced that identifies the contents of the file.

·       If the contents are modified in any way, the value of the hash will also change significantly.

·       Two algorithms are currently widely used to produce hash values: the MD5 and SHA1 algorithms.
