Sitting on your couch, recliner chair or on the floor and flipping through various television channels is not an uncommon practice in our society. The remote control allows you to stay in one place while doing so. How does the remote control of a television set work from a distance?

A

The remote generates a systematic series of gamma pulses that signal an ASCII code

B

The remote generates a systematic series of ultraviolet pulses that signal a binary code

C

The remote generates a systematic series of infrared pulses that signal a binary code

D

The remote generates a systematic series of microwave pulses that signal an ASCII code

Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. What inference can be drawn from the above?

A

All automatically controlled products and devices have microcontrollers.

B

Microcontrollers save money.

C

Both option 1 and option 2

D

Neither option 1 nor option 2

You want to provide Internet access for the clients on your network. You decide to use Network Address Translation (NAT). You have a Windows 2000 computer you try to establish a secure Virtual Private Networking session with. You try connecting to the Remote Windows 2000 computer using L2TP. You are unable to establish a connection with the remote node using L2TP. You are able to make a connection with another computer in your same office. Why are you unable to make a connection.to the remote location?

A

NAT does not allow for remote networking

B

L2TP does not work with Windows 2000 computers

C

You can not establish a L2TP connection behind a computer running NAT. The L2TP session fails because the IP Security packets become corrupted

D

You have not configured the NAT server to translate the IP Security packets

E

None of above
