- A.
C:\users\user1\documents to c:\users\user1\documents
- B.
C:\documents and settings\user1\my documents to c:\users\user1\documents

- D.
C:\users\user1\my documents to c:\users\user1\documents
Correct Answer
B. C:\documents and settings\user1\my documents to c:\users\user1\documentsExplanation
In Windows XP, the user's documents are stored in the "c:\documents and settings\user1\my documents" directory. However, in Windows Vista and newer versions, the directory structure changes and the user's documents are stored in the "c:\users\user1\documents" directory. Therefore, when moving the user's files from a Windows XP PC to a Windows Vista PC, the correct corresponding directories would be "c:\documents and settings\user1\my documents" on the Windows XP PC to "c:\users\user1\documents" on the Windows Vista PC.Rate this question:

Which of the following are items that can be configured on a wireless router to make it more difficult for attackers to gain access? (Select TWO).
- A.
Change the wireless channel
- B.
Disable SSID broadcast
- C.
Change SSID from default
- D.
Enable DES encryption
- E.
Turn on port forwarding
Correct Answer(s)
B. Disable SSID broadcast
C. Change SSID from defaultExplanation
Disabling SSID broadcast and changing the SSID from default are two measures that can be taken to make it more difficult for attackers to gain access to a wireless router. Disabling SSID broadcast prevents the router from broadcasting its network name, making it harder for attackers to identify and target the network. Changing the SSID from its default value adds an additional layer of security, as attackers often target networks with default configurations. These two actions combined can help enhance the security of a wireless router and make it more challenging for attackers to gain unauthorized access.Rate this question:
