  1. Password expiration

  2. Password reuse

  3. Password recovery

  4. Password disablement

Answer: A Explanation:

The password expiration setting determines that a user will not be able to log into a system without changing their password after the maximum password age has been reached.

Question No: 906 – (Topic 5)

One of the most basic ways to protect the confidentiality of data on a laptop in the event the device is physically stolen is to implement which of the following?

  1. File level encryption with alphanumeric passwords

  2. Biometric authentication and cloud storage

  3. Whole disk encryption with two-factor authentication

  4. BIOS passwords and two-factor authentication

Answer: C

Explanation: Whole-disk encryption only provides reasonable protection when the system is fully powered off. to make the most of the defensive strength of whole-disk encryption, a long, complex passphrase should be used to unlock the system on bootup. Combining whole-disk encryption with two factor authentication would further increase protection.

Question No: 907 – (Topic 5)

Which of the following security benefits would be gained by disabling a terminated user account rather than deleting it?

  1. Retention of user keys

  2. Increased logging on access attempts

  3. Retention of user directories and files

  4. Access to quarantined files

Answer: A Explanation:

Account Disablement should be implemented when a user will be gone from a company whether they leave temporary or permanently. In the case of permanently leaving the company the account should be disabled. Disablement means that the account will no longer be an active account and that the user keys for that account are retained which would not be the case if the account was deleted from the system.

Question No: 908 – (Topic 5)

An administrator implements SELinux on a production web server. After implementing this, the web server no longer serves up files from users#39; home directories. To rectify this, the administrator creates a new policy as the root user. This is an example of which of the following? (Select TWO).

  1. Enforcing SELinux in the OS kernel is role-based access control

  2. Enforcing SELinux in the OS kernel is rule-based access control

  3. The policy added by the root user is mandatory access control

  4. Enforcing SELinux in the OS kernel is mandatory access control

  5. The policy added by the root user is role-based access control

  6. The policy added by the root user is rule-based access control

Answer: D,F Explanation:

Enforcing SELinux in the OS kernel is mandatory access control. SELinux is Security Enhanced Linux which is a locked down version of the OS kernel.

Mandatory Access Control (MAC) is a relatively inflexible method for how information access is permitted. In a MAC environment, all access capabilities are predefined. Users can’t share information unless their rights to share it are established by administrators.

Consequently, administrators must make any changes that need to be made to such rights. This process enforces a rigid model of security. However, it is also considered the most secure security model.

The policy added by the root user is rule-based access control. The administrator has defined a policy that states that users folders should be served by the web server.

Rule-Based Access Control (RBAC) uses the settings in preconfigured security policies to make all decisions.
