Acollege has five campuses. each campus has ip phones installed. each campus has an assigned ip address range. for example, one campus has ip addresses that start with 10.1.x. x. on another campus the address range is 10.2.x. x. the college has standardized that ip phones are assigned ip addresses that have the number 4x in the third octet. for example, at one campus the address ranges used with phones include 10.1.40.x, 10.1.41.x, 10.1.42.x, etc. which two groupings were used to create this ip addressing scheme?
pick two
a. device type
b. support model
c. geographic location
d. department person

Based on the scenario, the two groupings that were used to create the ip addressing scheme is : 

a. Device type
c. Geographic location

This will be the most suitable because each campuses has an assigned IP address range

hope this helps 

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.
