What color is the wire conductor for pin 4 on a TIA-568 modular plug?

• White with blue stripe
• Solid orange
• Solid blue
• White with green stripe               

EXPLANATION

The TIA-568 cabling standard is as follows for both 568A and 568B configured cables:

TIA-568A

1. White with green stripe
2. Solid green

3. White with orange stripe

4. Solid Blue

5. White with blue stripe

6. Solid orange

7. White with brown stripe

8. Solid brown

For the TIA-568B standard:

1. White with orange stripe

2. Solid orange

3. White with green stripe

4. Solid Blue

5. White with blue stripe

6. Solid green

7. White with brown stripe

What is the common naming convention of PowerShell cmdlets and functions?

What is the common naming convention of PowerShell cmdlets and functions?

• Verb-Preposition-Noun
• Adverb-Verb-Noun
• Verb-Noun
• Adjective-Noun    

EXPLANATION

The common naming convention of cmdlets and functions in PowerShell is "Verb-Noun".

There are 3 primary rules for naming within this convention:

1. The Verb should be in the approved verb list.  To get the list of approved verbs, simply type "Get-Verb" in PowerShell.
2. The Noun should be singular, never plural.
3. Matching Nouns should work together and with the same object types; for instance, the object you get when you run Get-<Noun> should be able to be piped to a cmdlet to Set-<Noun>.

 What are the IDs assigned to ports like USB, Ethernet, and video ports called?

• MAC addresses
• I/O addresses
• Subnets
• Nodes         

EXPLANATION

Each I/O device connected to your computer is mapped to a unique I/O (Input/Output) address. These addresses are assigned to every I/O port on your computer, including USB, Firewire, Ethernet, VGA, and DVI ports, as well as any other ports your computer might have.

Which of the following conditions occurs when two packets are transmitted over a medium at the same time?

Which of the following conditions occurs when two packets are transmitted over a medium at the same time?

• Asynchronous
• Collision
• Synchronous
• Contention     

EXPLANATION

In a network, when two or more stations attempt to transmit a packet across the network at the same time, a packet collision occurs. This is not uncommon in a shared medium such as an Ethernet that has many computers in the same network segment. When a packet collision occurs, the packets are either discarded or sent back to their originating stations and then re-transmitted in a timed sequence to avoid further collision. Packet collisions can result in the loss of packet integrity or can impede the performance of a network
