You do not need to configure a certificate authority on your network to use EFS.
<em>EFS</em> is the short form for<em> Encryption File System</em>. With EFS, users can encrypt their files and folders and even the entire content of a given drive. By encrypting these files and folders, the access to them are restricted and thus increasing, improving and enhancing the security level of the users' data.
In other words, even though there are other ways to restrict access (such as using <em>logon authentication</em> and <em>NTFS file permissions</em>), EFS allows to add another layer of security to data.
To <em>encrypt</em> and <em>decrypt</em> data files and folders in EFS, a <em>certificate authority (CA)</em> could be used. This is however not a requirement. In the case where there is no certificate authority, EFS will sign a default certificate that will be used for encryption. In other words, <em>EFS will generate its own certificate</em> if none does not exist.
<em>The following are other things to note about EFS</em>
i. EFS uses a public and private key pair to encrypt data.
ii. Users do not need to enable EFS. It is enabled by default.
iii. For EFS to encrypt a file, the NTFS file system must be used.
Since a certificate authority is not required on your network to use EFS, the correct option is:
(b) False.

Answer:
Let P(x) = x is in the correct place
Let Q(x) = x is in the excellent place
R(x) denotes the tool
Explanation:
a) Something is not in the correct place.
P(x) is that x is in the correct place so negation of ¬P(x) will represent x is not in the correct place. ∃x is an existential quantifier used to represent "for some" and depicts something in the given statement. This statement can be translated into logical expression as follows:
∃x¬P(x)
b) All tools are in the correct place and are in excellent condition.
R(x) represents the tool, P(x) represents x is in correct place and Q(x) shows x is in excellent place. ∀ is used to show that "all" tools and ∧ is used here because tools are in correct place AND are in excellent condition so it depicts both P(x) and Q(x). This statement can be translated into logical expression as follows:
∀ x ( R(x) → (P(x) ∧ Q(x))
c) Everything is in the correct place and in excellent condition.
Here P(x) represents correct place and Q(x) represents excellent condition ∀ represent all and here everything. ∧ means that both the P(x) and Q(x) exist. This statement can be translated into logical expression as follows:
∀ x (P(x) ∧ Q(x)
