EXAMS 2026 COMPLETE QUESTIONS AND
ANSWERS GUARANTEED TO PASS
◉ Service Set Identifier (SSID). Answer: Wireless network name
◉ Wi-fi Protected Setup (WPS). Answer: Simplifies Wi-Fi
configuration but vulnerable to brute force attacks
◉ Stateful Packet Inspection (SPI). Answer: Firewall technique that
inspects incoming data packets to make sure they correspond to an
outgoing request
◉ Virtual Private Network (VPN). Answer: Establishes a secure
network connection, a way to protect your LAN's data from being
observed by outsiders
◉ Overloading. Answer: Technique where NAT translates the home
network's private IP addresses to a single public IP address
,◉ Port Address Translation (PAT). Answer: A port number is tracked
with the client computer's private address when translating to a
public address

◉ Straight-through. Answer: Transmit and receive signal pairs are
aligned end-to-end
◉ Crossover. Answer: Transmit and receive signal pairs are switched
◉ Uplink port. Answer: Allows the connection of a switch to another
switch without having to use a crossover cable
