EXAM 2024 LATEST PA AND OA EXAM SET WGU
VERIFIED EXAM
server - ANSWER: a computer that manages access to centralized services/resources
for other computers
hub - ANSWER: connects the router to the network, takes the data packets from the
router, and sends them to all the devices on the network (takes the electrical signal
and sends it to all the ports with devices connected to them)
switch - ANSWER: sends packets directly from the sender to the receiver without
other devices in the network being aware; a smarter hub
network interface card (NIC) - ANSWER: assigns each device its unique MAC address
router - ANSWER: the point of connection between TWO OR MORE networks that
forwards data packets between the networks
access point - ANSWER: interconnects wireless devices and provides a connection to
the wired LAN
modem - ANSWER: access point to the Internet; bridge between customer network
and ISP
-converts incoming analog data to digital and outgoing digital data to analog
Internet vs. internet - ANSWER: Internet = worldwide Internet
internet = a network of networks
twisted cables (STP or UTP) - ANSWER: inside the cable, 4 pairs (8 total wires) are
twisted together to reduce interference
-STP: shielded, uses mesh/foil shield to block further interference
-UTP: unshielded
fiber optic cabling - ANSWER: transmits data by using pulses of light and can transmit
over very large distances
- high security and not interfered with by radio signals
wireless ad hoc - ANSWER: LAN that is built as devices are added/connected to each
other; each device can connect to the central wireless device and each other
infrastructure network - ANSWER: normal LAN that adds an access point to allow for
wireless connection as well
analog vs. digital - ANSWER: -analog = sends data in waves
-digital = uses binary code
, star topology - ANSWER: all devices radiate out around a central hub/switch
ring topology - ANSWER: all devices are connected to two others and form a ring;
devices use tokens to determine access
bus topology - ANSWER: all devices are connected to a central cable in a line; devices
can only access the cable 1 at a time
mesh topology - ANSWER: all devices in a network are connected to all other devices
in that network
ipconfig - ANSWER: shows the IP configuration of your computer
ipconfig/all - ANSWER: shows more detailed information about network settings
ipconfig/flushdns - ANSWER: flushes the DNS cache, which clears any stored IP
addresses or other DNS records
DNS (Domain Name System) - ANSWER: translates a name (ex. www.google.com)
into its IP address
Nslookup - ANSWER: how you talk to the DNS server to find a domain name's (ex.
www.google.com) IP address
ping - ANSWER: tests communication to a remote device (no response = networking
issue, ping does not tell you where the issue is)
tracert - ANSWER: shows the path a packet takes between two hosts, also tests
communication to a remote device (no reply = networking issue, and tracert shows
you where the issue is)
route - ANSWER: shows the route packets will take to their destination
ARP-a - ANSWER: shows IP addresses and corresponding MAC addresses of remote
computers (showing you the ARP cache) (if you hear ARP, think MAC)
ARP (Address Resolution Protocol) - ANSWER: translates IPs into MAC addresses
(AKA physical addresses = MAC)
netstat - ANSWER: shows a list of all remote devices that your computer has
communicated with (active/recent TCP connections)
NMap - ANSWER: shows you what ports are open/closed (open = that port is
installed and listening for connections)
