SRWE MODULE 2 | COMPLETE PRACTICE QUESTIONS, ANSWERS &
STUDY GUIDE 2026/2027
Port Density - ANS ✔✔the number of ports available on a single switch
Frame Buffers - ANS ✔✔The ability of the switch to store frames while processing them.
ASIC - ANS ✔✔An integrated
circuit designed for a particular use
instead of for general-purpose uses. Use of this component in a switch allows for quick forwarding
decisions.
cyclic redundancy check (CRC) - ANS ✔✔Mathematical error-checking mechanism.
Error Checking - ANS ✔✔Checks if frame is free of physical and data-link errors before sending otherwise
frame is.
Ingress - ANS ✔✔Port where the message enters
Egress - ANS ✔✔The term used to describe frames leaving the device from a particular port
FCS - ANS ✔✔error checking process
Automatic Buffering - ANS ✔✔Provides flexibility to support a variety of Ethernet speeds
Collision domains - ANS ✔✔network segments that share bandwidth between devices; if two or more
devices try to communicate at the same time, a data collision will occur
Hub - ANS ✔✔Layer 1 network device that connects multiple end devices; sends frames out all ports
Microsegmentation - ANS ✔✔each connection is its own collision domain
Broadcast domain - ANS ✔✔all devices and media in a network segment that will forward broadcast
packets; bounded by layer 3 devices
Congestion - ANS ✔✔slow-down in network performance due to high traffic
Full-duplex - ANS ✔✔transmit and receive signals travel the network medium at the same time
MAC Table - ANS ✔✔Determines how to forward traffic through the switch; aka CAM
store and forward - ANS ✔✔The entire frame of data is received before any decision is made regarding
forwarding the data packet to its destination
