Establishing a method to erase or clear cluster tips is an example of securing which of the following?
A.
Data in transit
B.
Data at rest
C.
Data in use
D.
Data in motion
Explanation:
A computer hard disk is divided into small segments called clusters. A file stored on a hard disk usually
spans several clusters but rarely fills the last cluster, which is called cluster tip. This cluster tip area may
contain file data because the size of the file you are working with may grow or shrink and needs to be
securely deleted. Data stored on the hard drive is called data at rest.
Incorrect Answers:
A: Data in transit is data that is being transferred over a network. However, cluster tips are used on hard
disks where data is stored. Data storage is referred to as data a rest.
C: Data in use is data being actively processed by an application. However, cluster tips are used on hard
disks where data is stored. Data storage is referred to as data a rest.
D: Data in motion is not a valid terms. The correct term is data in transit, which refers to data that is being
transferred over a network. However, cluster tips are used on hard disks where data is stored. Data
storage is referred to as data a rest.https://uwnthesis.wordpress.com/2013/07/10/ccleaner-how-to-configure-ccleaner-to-wipe-cluster-tipson-drive/
