VLSM stand for Variable Length Subnet Mask.VLSM originally
defined in RFC 1812, allows you to apply different subnet
masks to the same class address space.
Remember that the best subnet mask for point-to-point links
is 255.255.255.252(130).
VLSM allows you to use more than one subnet mask for given
class address.Remember the two major advantages of VLSM:
More efficient use of address and route
summarization/aggregation.
Static routing, because we first check the A.D value which
is administrative distance. A.D of static is 1 where as rip
having 120, eigrp -90 and ospf- unlimited. We consider the
best route is that who's A.D value lest like static routing.

The choices A,C and D are important to protect the assets

Dynamic NAT contains mulitple public IPs and when the user
needs to go to WAN he will get an IP. If all IPs are used,
the user must wait to get one public IP.
NAT Overloading has only one public IP and all users on the
LAN network are usig this IP but with different ports.
NAT Overloading is much better than Dynamic and static
since it is more secure and to save IPs.
