Here are some command prompt commands to know:

route print, or netstat -r (to show routing table)

netstat -n (to show ip sessions & port numbers)

tracert, pathping, mtr (linux) (to show hop distance / route to destination network)

See if you can understand this cheat sheet: http://www.aelius.com/njh/subnet_sheet.html

************************************************************** 

NOTE: In the Mike Myers Learnkey Video CompTIA Network+ it is stated that a subnet with All “zeros” or All “ones” cannot be used.  This used to be correct.  According to the below statement in RFC 1878.  This practice was officially declared obsolete in 1995. The below statement is a quote from wikipedia: http://en.wikipedia.org/wiki/Subnetwork

Subnet zero and the all-ones subnet:

The first subnet obtained from subnetting has all bits in the subnet bit group set to zero (0). It is therefore called subnet zero.[6] The last subnet obtained from subnetting has all bits in the subnet bit group set to one (1). It is therefore called the all-ones subnet.[7]

The IETF originally discouraged the production use of these two subnets at one point due to possible confusion of having a network and subnet with the same address.[8] The practice of avoiding subnet zero and the all-ones subnet was declared obsolete in 1995 by RFC 1878, an informational, but now historical RFC.[9]

Cisco Article: Link

According to RFC 950, “Traditionally, it was strongly recommended that subnet zero and the all-ones subnet not be used for addressing.”  RFC 950 was developed in 1985 and was replaced by RFC 1878, in 1995.  It is stated that in some cases with older network systems RFC 950 may still be of use (subnet zero and the all-ones subnet not for use).  However, RFC 950 is widely considered obsolete.

Here are some cabling standards to memorize:

Link: Good article on Ethernet Cables (Cat5e, Cat6), to include PoE

Link: PoE (Power Over Ethernet) Wikipedia

PI Manufacturing in Walnut, CA is an excellent resource for cabling needs.  They also have ‘Will Call”.

PI MFG Link: Cat5e, Cat6 cables
