Q111. An administrator notices that former temporary employees’ accounts are still active on a domain.
Which of the following can be implemented to increase security and prevent this from happening?
A. Implement a password expiration policy.
B. Implement an account expiration date for permanent employees.
C. Implement time of day restrictions for all temporary employees.
D. Run a last logon script to look for inactive accounts.
Answer: D
Explanation:
You can run a script to return a list of all accounts that haven’t been used for a number of days, for example 30 days. If an account hasn’t been logged into for 30 days, it’s a safe bet that the user the account belonged to is no longer with the company. You can then disable all the accounts that the script returns. A disabled account cannot be used to log in to a system. This is a good security measure. As soon as an employee leaves the company, the employees account should always be disabled.

Q116. Joe, an employee is taking a taxi through a busy city and starts to receive unsolicited files sent to his Smartphone. Which of the following is this an example of?
A. Vishing
B. Bluejacking
C. War Driving
D. SPIM
E. Bluesnarfing
Answer: B
Explanation:
Bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as mobile phones, PDAs or laptop computers, sending a vCard which typically contains a message in the name field (i.e., for bluedating or bluechat) to another Bluetooth-enabled device via the OBEX protocol. Bluetooth has a very limited range, usually around 10 metres (32.8 ft) on mobile phones, but laptops can reach up to 100 metres (328 ft) with powerful (Class 1) transmitters. Bluejacking is usually harmless, but because bluejacked people generally don't know what has happened, they may think that their phone is malfunctioning. Usually, a bluejacker will only send a text message, but with modern phones it's possible to send images or sounds as well. Bluejacking has been used in guerrilla marketing campaigns to promote advergames.
Q117. An insurance company requires an account recovery process so that information created by an employee can be accessed after that employee is no longer with the firm. Which of the following is the BEST approach to implement this process?
A. Employee is required to share their password with authorized staff prior to leaving the firm
B. Passwords are stored in a reversible form so that they can be recovered when needed
C. Authorized employees have the ability to reset passwords so that the data is accessible
D. All employee data is exported and imported by the employee prior to them leaving the firm
Answer: C
Explanation:
Since a user’s password isn’t stored on most operating systems (only a hash value is kept), most operating systems allow the administrator (or authorized person in this case) to change the value then the information/files/documents can be accessed. This is the safest way of recovery by an authorized person and is not dependent on those who leave the firm.
