| Welcome, quizfans!
OK the forum is pretty dead today so I decided to "kick it up a notch." Here's a couple i-Net+ questions for everyone to chew on. You are not allowed to reference material for these questions, once you read them, reply with your answer immediately from your knowledge. OK? Begin.
__________________
Question 1
Which of the following protocols does Microsoft's Active Directory rely upon?
A) IPX
B) LDAP
C) ADP
D) DHCP
-- For extra credit: The correct answer is based upon an earlier standard. Name it.
Question 2
What is the speed of a DS3 (Digital Service 3) line?
A) 1.544 Mbps
B) 2.048 Mbps
C) 43 Mbps
D) 100 Mbps
-- For extra credit: DS1, DS2, and DS3
lines are all composed of multiple
channels. How many channels are in a
DS1?

| DS3 lines are capable of supporting data transmissions up to 34.368 Mbps and E1 also called DS1 is a 30 channel digital line | |
|
| Question 1
B. LDAP
EC. X500 ?
Question 2
Never heard of it. So Ill throw a wild guess and say C. | |

| Ouch, this sure proved popular 
Nevertheless, 'everyone' did a nice job... Nothing wrong with guessing 
Here are the anxiously-awaited answers:
__________________
Question 1
B) LDAP - Lightweight Directory Access Protocol is used by a client to access a directory server, just like it is implemented in Microsoft's Active Directory. It is discussed in RFCs 1777, 1778, 1823, and 2253. It uses port 389.
A) IPX is not used by Active Directory.
C) ADP is an invented term (to my knowledge).
D) DHCP is used for dynamic configuration of IP hosts, and Active Directory does not rely upon it.
X.500 was the basis for LDAP, although the Lightweight indicates that LDAP has fewer features and uses less resources. Also, only LDAP supports TCP/IP.
Question 2
C) 43 Mbps is the speed of a DS3 line. DS3 is the same as a T3 line. A DS3 consists of 28 T1s, or 672 individual channels.
Some sites list the actual speed of a T3/DS3 as 45.736 Mbps... in the absense of 45 as an answer, 43 is the best answer.
A) 1.544 Mbps is the speed of a T1/DS1 line.
B) 2.048 Mbps is the speed of an E1 line.
D) 100 Mbps is not a valid line speed for any DS/T/E series carrier.
24 channels are in a full T1 or DS1. Each channel is 64 Kbps. I asked for the channel count of a DS1 instead of a DS3 to see if I would trip anyone up.
