CTS questions with accurate answers
• 1 Gbps Correct Answers o "Gigabit Ethernet"
o Deployed as network backbone
o Connects switches and routers, and servers with Gigabit Ethernet NICs
o Backwards compatible also
• 10 Gbps Correct Answers o Intended for use as a backbone
o Connects switches to each other
o Increased range of Ethernet connections
Allowed ISPs to use Ethernet for WANs
o Can interconnect clusters of servers
Communication pathway for supercomputers
o Connect an organization directly to an ISP site
o Connect switches within an ISP network
• 10 Mbps Correct Answers o "classic Ehternet"
o Sometimes still connects end nodes, like comps to switches
• 100 Mbps Correct Answers o "fast Ethernet"
o Connect end nodes to switches and network access equipment and
servers
,• 3 Characters of Color Correct Answers o Hue - attitude of color - red,
blue, green
o Greyscale - brightness and darkness, "value"
o Chroma - saturation or intensity
• NOTE: black is the absence of light
• 3 Types of Direct View Display types Correct Answers o Receivers
(TVs)
o Video Displays
o Computer Displays
• 40/100 Gbps Correct Answers o Main purpose is to aggregate slower
connections
o 40 Gbps used for data center applications
o 100 Gbps intended for aggregating 10 Gbps switches and providing
ISP and network backbones
• Access control list (ACL) Correct Answers o Rights of each user is
governed by this
o Controls what travels through router
o Configured on router
• Amplifier Correct Answers o Last before loudspeaker
o Takes signal from line level to loudspeaker level
,• Amplitude - Correct Answers magnitude of wave
o Intensity
o Larger = brighter
• Analog to Digital Conversion: Sampling Rate Correct Answers how
many times a digital sample is taken of the analog sample, per second
Ex. CD Sampling rate = 44.1kHz
Called Pulse Code Modulation (PCM)
Determines digital signal's accuracy
• Analyze the site for environment/benchmarking Correct Answers o
Determine contraints such as work hours, noise levels, security issues
o Take note of acoustics, lighting and seating.
Use meters for light and audio analysis
Not too detailed
• Application Correct Answers - activity or process that supports the end
user's communication need(s)
o i.e. - sales force education and coordination, product demonstrations,
musical performance etc.
• Application Layer Gateway (ALG) Correct Answers o Works in
parallel with firewall
o Examines each packet before forwarding along
o Needs firewall with NAT
, o Supports videoconferencing
o Need separate device for each firewall
• Application of color temperature Correct Answers o Video cameras
need electronic adjustments for what "white" it should be
o Monitors or projectors change whiteness based on lighting conditions
of environment
• Ask Questions: Types Correct Answers o Open questions - requires
more than a word or two to answer
Gets them talking
o Closed - for factual or specific information
o Directive - for when youre trying to persuade them that one of your
ideas will work well
Questions that suggest their own answer
• Audio
o Sound Reinforcement Correct Answers Combination of mics, audio
mixers, signal processors, power amplifiers, and loudspeakers that are
used to electronically amplify and distribute sound
• Audio signal levels Correct Answers o Mic level - mV
o Preamplifier - amplifies mic level to line level
o Line level - used for routing and processing
Can be 1.23 V for professional
