EXTRON CONTROL SPECIALIST PRACTICE EXAMINATION
2026 QUESTIONS WITH ANSWERS GRADED A+
● Network. Answer: Collections of computers or hardware that is connected physically or
logically.
● Local Area Network. Answer: Uses physical wiring to connect devices. Comprised of
computers, peripheral devices, and local servers. The server provides access to shared apps,
printers, and disk storage.
● Decoder. Answer: Takes the encoded signal and converts it back to the original signal, or
into a new video or audio format.
● Encoder. Answer: Takes info from one video or audio format and converts it to another.
● Wireless Local Area Network (WLAN). Answer: Connects wireless devices to each other
using high frequency radio signals to communicate data. AKA wi-fi.
● Wide Area Network (WAN). Answer: Connects networks that are located in different
geographical locations. Provide communication as one large network for smaller networks or
LANs.
● Virtual Private Network (VPN). Answer: Lets users on less secure networks send and
receive data more securely. Also allow employees to be at home or travel and access their
company's network remotely.
● Virtual Local Area Network (VLAN). Answer: Virtual, logical connection of multiple
devices from different LANs into one network. For example, you can group multiple devices
together in a this network to reduce traffic across the larger network.
● Broadcast Domain. Answer: A collection of devices that receive broadcast traffic from
each other.
● Audio Video Local Network. Answer: Dedicated network specifically for providing secure
control of local AV devices without outside interference or intrusion. Similar to a VLAN since it
creates a separate broadcast domain for the AV devices. Allow the AV system to run even if
it's been disconnected from the LAN.
● Pro Series. Answer: This Extraon product series has an AV LAN port
, ● AV LAN Port. Answer: Provide Power over Ethernet, allowing communication with
supported devices such as touch panels.
● Ways a network can be classified.. Answer: Number of devices, scope, ability
● Intranet. Answer: Private network that resembles the internet. It is secured through
firewalls that hide its data.
● Extranet. Answer: a private network connecting more than one organization. It uses VPN
technology to allow limited network access
● Packet. Answer: units of data transmitted over the network. Before being sent, the data is
divided into manageable segments to that information can be transmitted more efficiently
instead of in a large, single file.
● Packet switching. Answer: A type of network communication in which data traffic is split
into parts.
● Destination. Answer: Packets are labeled with a ________ address.... for transmitting
across the network.
● sequence. Answer: Packets are labeled with a...... __________ number for transmitting
across the network.
● Devices. Answer: During transmission, the data packets travel through various
___________ to reach their destination.
● Reassembled. Answer: The original data is ____________ in the correct order, based on
the sequence number contained within the message packet.
● Internet Protocol. Answer: The set of rules that define how computers and devices
communicate over a network
● IPv4. Answer: The most common type of IP. Used by Extron.
● Transmission Control Protocol (TCP). Answer: defines the amount of traffic over the
network and is responsible for actual delivery of the data.
● Connection-oriented protcol. Answer: once a connection is established, packets can be
sent in two directions. TCP is considered this.
● TCP/IP. Answer: TCP and IP working together to control network data transmission.
