Hi! I have been posted content of ccna1 final exam (latest and only question.) I will post the answer and insert image on sunday. If you care, please subscribe your email an become a first person have full test content. Subcribe now Some question have not content because this question have images content. So that can you wait for me? SUNDAY 1. A user sees the command prompt: Router(config-if)# . What task can be performed at this mode? Reload the device. Perform basic tests. Configure individual interfaces. Configure individual terminal lines. 2. Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C. During this attempt, a frame was captured with the source MAC address 0050.7320.D632 and the destination MAC address 0030.8517.44C4. The packet inside the captured frame has an IP source address 192.168.7.5, and the destination IP address is 192.168.219.24. At which point in the network was this packet captured? leaving host A leaving ATL leaving...

ReplyDeleteUsing JNA, you can call Win32 Kernel32's GetVolumeInformation() to retrieve lpFileSystemNameBuffer parameter which receives the name of the file system, for example, the FAT file system or the NTFS file system http://msdn.microsoft.com/en-us/library/windows/desktop/aa364993(v=vs.85).aspx

What version of Java are you using?
ReplyDeleteIf Java 7 - Check out this API - http://docs.oracle.com/javase/7/docs/api/java/nio/file/FileSystems.html
Outside of that I know System.getProperty and Runtime have methods to grab information on the disk being used but nothing that specifically calls out the File System type (NTFS, FAT32, etc.)
