True or False: When connections are made to other systems using NetBIOS communications, the system will maintain a list of other systems connected. By viewing the contents of the name table cache, an investigator might be able to find other systems affected. ✔✔True
(A cache is duplicate data stored in a temporary location so a computer can rapidly access that data. In this case, the NetBIOS Remote Cache Name Table may contain a list of systems that a computer has connected to.
nbtstat - c can be used to view the cache of NetBIOS names on the host operating system)

What command can be used to view command history? ✔✔doskey /history & scroll up in the command window
(If a command window is open, the investigator can scroll up to see command history. But the attacker may have typed cls to clear the screen. Then, the investigator can use the doskey /history command to see the history.)

What files contain pool headers? ✔✔Pooltag.txt
(Windows memory manager generally allocates memory in 4KB pages. Sometimes, 4K would be too large and waste memory. So memory manager allocates several pages ahead of time thus keeping an available pool of memory.)
