The answers to these questions should be in your study guide. What study gudie are you using?
Anyway, here goes with my answers;
1, 156.100.11.37 with mask:255.255.240.0 will generate a number of subnets in the final octect, for example 156.100.11.0. These subnets, known as 'subnet-zero' are not usually allowed, however Cisco overcome this problem by putting a command in global config mode of ' ip subnet-zero', to tell the router to ise any subnet-zero it finds.
2, Multiprotocol routing is a router's ability to handle and process more than one routing protocol at a time.
3, Don't know, possibly a loop back test on an ethernet NIC card
4, None of the options you have listed are vaild Cisco commands. To see the value of the config register, try 'show version'
5, erase startup-config
Please remember that the people on this forum prefer that you attempt to read the relevant chapter in your study guide first, then if you still have a problem, post a message - and keep it to one or two questions at the most.
Hope this helps.

The resulting subnets from 156.100.11.37 255.255.240.0 are 156.100.0.0/20, 156.100.16.0/20, 156.100.32.0/20, 156.100.48.0/20, etc. 156.100.11.37 belongs to the first subnet (which has a host address range 156.100.0.1 through 156.100.15.255). Go with Hippo from now on.

I believe the question implies you end up in ROMMON (since the router is not booting properly...), so the answer should be o

Subnet zero is the first subnet you get. It is so called because it looks exactly like the major network you're subnetting (that is, with zeros in the host part of the major network). In your example:
Major net: 156.100.0.0/16
Subnets (with 255.255.240.0):
156.100.0.0/20 <-- looks like the major net
156.100.16.0/20
156.100.32.0/20
etc.
Better now?!
