In PowerShell, what is the built-in alias for the ForEach-Object command ?

• %
• fe
• ?
• ^ 

EXPLANATION

In order to cut down on the amount of code you have to write, you get handy alias such as:

% - ForEach-Object
? - Where-Object

It just makes coding that much easier but can reduce the understandability of the code.

To what bridge on the motherboard is the CPU connected?

• Southbridge
• Northbridge
• Eastbridge
• Westbridge

EXPLANATION

The Northbridge is one of two chips in the chipset architecture on a PC motherboard. The second chip is called Southbridge.
Northbridge is connected directly to the CPU via the FSB (front-side bus) and is responsible for tasks that require the highest performance. Also RAM (and integrated graphics) is located on the Northbridge.

The convergence of traditional audio-video systems and high-bandwidth, low latency networking is know as what?

• AV Over IP
• Mesh AV
• HD BASE-T
• AV Over Fiber 

EXPLANATION

AV over IP uses existing or additional networking infrastructure to transport encoded AV streams from source to destination without requiring costly dedicated AV cabling and switching equipment.
This permits organizations to leverage their existing equipment and cabling often without significant modification.

If I twist the pairs as close as I can to the tip of an Ethernet connector, what am I reducing?

If I twist the pairs as close as I can to the tip of an Ethernet connector, what am I reducing?

• Power Redundancy
• Electromagnetic Radiation
• Mold Buildup
• Heat Dissipation 

  EXPLANATION

Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility. Compared to a single conductor or an untwisted balanced pair, a twisted pair reduces electromagnetic radiation from the pair and cross-talk between neighboring pairs and improves rejection of external electromagnetic interference.
