Question #81
A corporate network just implemented a 60-day password-warning banner.
Which of the following is most likely going to happen in 60 days?
- A . Password reset
- B . Password expiration
- C . Password reuse
- D . Password Implementation
Correct Answer: B
B
Explanation:
The most likely thing that will happen in 60 days after implementing a 60-day password-warning banner is password expiration. A password-warning banner is a message that appears on the screen when a user logs in to a system or network, informing them of how many days are left before their password expires. A password expiration policy is a security measure that requires users to change their passwords periodically, usually every 30 to 90 days. This policy helps to prevent unauthorized access or compromise of passwords by hackers or malicious insiders. Password reset is the process of changing or creating a new password for a user account when the user forgets their password or wants to change it for security reasons. Password reset can be done by the user themselves or by an administrator, depending on the system or network settings. Password reset does not necessarily happen in 60 days after implementing a 60-day password-warning banner, unless the user forgets their password or chooses to change it before it expires. Password reuse is the practice of using the same password for multiple user accounts or systems. Password reuse is not recommended as it increases the risk of compromise if one of the accounts or systems is breached by hackers or malicious insiders. Password reuse does not necessarily happen in 60 days after implementing a 60-day password-warning banner, unless the user chooses to use their old password for their new password after it expires. Password implementation is not a term used in security, but it may refer to the process of creating or enforcing password policies for user accounts or systems. Password implementation does not necessarily happen in 60 days after implementing a 60-day password-warning banner, unless there are changes in the password policies that require users to comply with them.

Question #82
A company has installed an application that only requires a workstation to function.
Which of the following architecture types is this application using?
- A . One-tier
- B . Two-tier
- C . Three-tier
- D . n-tier
Correct Answer: A
A
Explanation:
One-tier architecture is a type of architecture that uses only one layer or tier for an application or system. In one-tier architecture, the application logic, data, and user interface are all contained within the same layer or tier. One-tier architecture would be the best description of a technology that allows an application to run on a workstation without requiring any other components or layers. Two-tier, three-tier, and n-tier architectures are types of architectures that use more than one layer or tier for an application or system. In two-tier architecture, the application logic and data are separated into two layers or tiers. In three-tier architecture, the application logic, data, and user interface are separated into three layers or tiers. In n-tier architecture, the application logic, data, and user interface are separated into multiple layers or tiers.

Which of the following is the equivalent of 1 KB?
- A . 0.01 googol
- B . 1,000 bits
- C . 8,000 bits
- D . 8,000 bytes
Correct Answer: C
C
Explanation:
1 KB (kilobyte) equals approximately 8,000 bits. This calculation is based on the understanding that 1 byte consists of 8 bits, and a kilobyte is made up of about 1,000 bytes. Therefore, multiplying these values together gives us 8,000 bits for 1 kilobyte.

Question #86
A large payment website was breached recently. A user is concerned that the breach will affect account security on other sites.
Which of the following password best practices would mitigate this risk?
- A . Password history
- B . Password reuse
- C . Password expiration
- D . Password age
Correct Answer: B
B
Explanation:
Password reuse is the practice of using the same password for multiple accounts or services. Password reuse would increase the risk of account security on other sites if a large payment website was breached recently. If the attackers obtained the user’s password from the breached website, they could try to use it to access the user’s accounts on other sites. Password reuse should be avoided and different passwords should be used for different accounts or services. Password history, password expiration, and password age are not password best practices that would mitigate this risk. Password history is the record of previous passwords that a user has used for an account or service. Password expiration is the time limit for using a password before it needs to be changed. Password age is the length of time that a password has been in use.
