AVIXA CTS STUDY GUIDE 2026 QUESTIONS AND
SOLUTIONS RATED A+
✔✔Signal separation in racks: - ✔✔One signal type per bundle
✔✔Do not put speaker and microphone cables... - ✔✔In the same conduit to avoid
signal distortion
✔✔Keep cable away from? - ✔✔Electrical signals
✔✔.002 volts - ✔✔Mic level audio
✔✔.775 volts - ✔✔Line level audio
✔✔load safety ratio for equipment install? - ✔✔5:1
✔✔Point source speakers - ✔✔Deliver very loud sound from 1 location (array or cluster)
✔✔For ISO (most common) rated Hardware what kind of bolts - ✔✔8.8 for AV install
✔✔For mounting ASTM and SAE bolts - ✔✔Use no less than Grade 5
✔✔Distributed speakers - ✔✔Suspended overhead or installed in ceiling.
✔✔Node - ✔✔Any device that sends data
✔✔Every node has a$ - ✔✔MAC address
✔✔ST - ✔✔Stab and twist connector.
✔✔3 common network connections - ✔✔Cat, optical, WiFi
✔✔Multimode Fiber - ✔✔Shorter cable runs - bundles of info. Not as efficient as single
mode for distance.
✔✔Why is fiber popular? - ✔✔No EMI, high bandwidth, long distance, bend radius is
improved, more affordable, more reliable, safer, easy to terminate
✔✔Single mode fiber - ✔✔Capable of long distance , small core.
✔✔569 and 569 cat cables. - ✔✔Blue and brown go together.
✔✔SC Connector - ✔✔stab and click - Used a lot in AV
, ✔✔Lc - ✔✔Small connector
✔✔Star Lan - ✔✔Nodes Comnet to a central point
✔✔Mesh network - ✔✔All nodes connect to each other - expensive. Partial mesh is
more common. Popular
✔✔WAN - ✔✔Talks network to network - no longer uses Mac. Uses DNS
✔✔VLANs - ✔✔Logically separate networks within networks. Devices talk mostly to
each other and need to stay secure. Such as signage applications
✔✔VPN - ✔✔Secure tunnel between LANs - encrypted
✔✔IP - ✔✔Internet Protocol. The main delivery system for information over the Internet
✔✔IP address - ✔✔3 parts - network bit, host bits. Subnet mask
✔✔IPv4 Subnet Mask - ✔✔In IPv4 addressing, a 32-bit number that, when combined
with a device's IP address, indicates what kind of subnet the device belongs to.
✔✔IPv4 vs IPv6 - ✔✔IPv4: 32-bit number: 4 billion addresses; four sets of numbers
marked off by periods
IPv6: 128-bit addresses, able to handle up to 1 quadrillion addresses; almost unlimited
# of addresses
✔✔10. - ✔✔Local large networks
✔✔127. - ✔✔Reserved for loop back
✔✔255 - ✔✔Reserved Broadcast
✔✔224. - ✔✔Reserved multicast
✔✔172 - ✔✔Local medium networks (guest)
✔✔192 - ✔✔Reserved Small networks
✔✔240 - ✔✔Reserved experimental
✔✔Class b Local address medium - ✔✔172.16.0.1
