DRAG DROP
You create an assembly named Assembly1.dll.
You need to ensure that Assembly1.dll can be deployed to the global assembly cache (GAC).
Which commands should you run? (To answer, drag the appropriate programs to the correct
locations. Each program may be used once, more than once, or not at all. You may need to
drag the split bar between panes or scroll to view content.)
Answer: 
I think it should be sn.exe and gacutil.exe
gacutil.exe command has not /out and /keyfile option,
but al.exe command has them.

1) sn.exe
2) al.exe
The following scenario outlines the process of signing an assembly with a strong name.
Assembly A is created with a strong name using one of the following methods:
1) Using a development environment that supports creating strong names, such as Visual Studio 2005.
2) Creating a cryptographic key pair using the Strong Name tool (Sn.exe) and assigning that key pair to the assembly using either a command-line compiler or the Assembly Linker (Al.exe). The Windows Software Development Kit (SDK) provides both Sn.exe and Al.exe.
