Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
Answer:
you cannot obtain a new copy of the keys that you have stored on Hardware Security Module, because they are lost forever and a new copy cannot be obtained if a copy is not kept somewhere.
Explanation:
Hardware Security Module (CloudHSM) is a cloud-based hardware security module (HSM) that provides the user the opportunity to create and utilize your own encryption keys on the AWS Cloud. It is a fully managed service that takes care of time-consuming administrative activities such as software patching, backups, hardware provisioning, and high-availability for the user.
One of the key elements of the Hardware Security Module (CloudHSM) is that a copy of the keys stored must be kept somewhere because if keys are lost, they are lost forever and a new copy cannot be obtained if a copy is not kept.
Therefore, you cannot obtain a new copy of the keys that you have stored on Hardware Security Module, because they are lost forever and a new copy cannot be obtained if a copy is not kept somewhere.

Answer:
Moderate.
Explanation:
A breach of security can be defined as any incident which results in an unauthorized access or privileges to a network, computer, software application, classified informations or data and services. There are three (3) levels of impact on an individual or organization when there's a breach of security; low, moderate and high.
A moderate level breach of security could cause a significant degradation in mission capability to an extent and duration that the organization is able to perform its primary functions, but the effectiveness of the functions is significantly reduced. It causes a serious adverse effect on individuals, employees or organizational assets and operations.
<em>However, in order to prevent a breach of security, it is advisable to use the following programs: firewall, demilitarized zone (DMZ), Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) etc. </em>
