Application Layer - correct answer the fifth layer this is essentially the data you have
requested being delivered to you.
Are ARP table entries permanent? - correct answer No the ARP table entries generally
expire after a short amount of time to ensure changes in the network are accounted for.
Autonomous System Number (ASN) - correct answer Numbers assigned to individual
autonomous systems. And are 32 bit numbers.
computer networking - correct answer The name we've given to the full scope of how
computers communicate with each other.
Cyclical redundancy check(CRC) - correct answer an important concept for data
integrity, and is used all over computing not just networking. this basically runs
calculations to make sure the product of the calculation matches up with the checksum
number received if not matched the data is thrown out.
data packet - correct answer An all-encompassing term that represents any single set of
binary data being sent across a network link.
Destination MAC address - correct answer the hardware address(or MAC) of the
intended recipient
Fiber cables - correct answer Short for fiber optic. Contain individual optic fiber, which
are tiny tubes made out if glass about the width of a human hair.
How are VLANS used? - correct answerThey are used to segregate different forms of
network traffic.
How does a Subnet mask work? - correct answerThey use AND operators to determine
if an IP address exists on the same network.
How does basic routing work in order? - correct answer1.the router receives data on
one of its interfaces.
2. The router examines the destination IP of the packet.
3. The router then looks up the destination network of the IP in its routing tables.
4. The router forwards the data out through the interface that is closest to the remote
network.
How does the operator AND work? - correct answerIt returns true if both values are
true.
, How does the OR operator work? - correct answerIt looks at each digit and if either of
them is true the result is true
How many columns will the most basic routing tables have? And what are they? -
correct answer4 columns which are the destination network, Next hop, Total hops, and
Interface.
How many network interfaces can a router have? - correct answerAt least two.
inter-network - correct answerA collection of networks connected together through
routers, the most famous of these being the Internet
Modulation - correct answera way of varying a voltage when traveling across cables.
protocol - correct answera defined set of standards that computers must follow in order
to communicate effectively.
the VLAN(Virtul LAN) header - correct answerIndicates that the frame itself is what's
called a VLAN frame
Transport Layer - correct answerThe fourth layer Sorts out which client and server
programs are supposed to get the data received. Such as how you can open multiple
websites on different tabs.
twisted-pair cable - correct answerfeatures pairs of copper wires twisted together.
Virtual LAN (VLAN) - correct answerA technique that lets you have multiple logical
LANs operating on the same physical equipment
What are data packets known as on the Ethernet level? - correct answerThey are
known as ethernet frames.
What are distance vector protocols? - correct answeran older standard for routers.
When using this protocol a router takes its routing table and the total hops of all
networks on the table and sends this list to every router directly connected to it.
What are exterior gateway protocols? - correct answerProtocols which are used for the
exchange of information between independent autonomous systems.
What are interior gateway protocols? - correct answerA protocol used by routers to
share information within a single autonomous system.
What are link state protocols? - correct answerEach router advertises the state of the
link of each of is interfaces. These interfaces can be connected to other routers or direct
connections to networks.
